Answer:
x = 16 or -2
Step-by-step explanation:
If both lines are congruent, their magnitudes are equal.
To find the magnitude of a line, the equation to use is;
D = √(x2-x1)^2 + (y2-y1)^2
So for AB, we have
D = √(-2 + 11)^2 + (5 + 3)^2
D = √81 + 64 = √145
For the second line
The distance would be;
D = √x-7)^2 + (9-1)^2
D = √(x-7)^2 + 8^2
Equate both magnitude
√145 = √(x-7)^2 + 64)
Simply remove the square roots on both sides
145 = 64 + (x - 7)^2
145 -64 = (x -7)^2
81 = (x-7)^2
Thaw the square root of both sides
x - 7 = 9
or x -7 = -9
x = 9 + 7 or x = -9 + 7
x = 16 or -2

Jack and Jill went to Taco Bell. Jack bought three tacos and two burritos
and paid $5.40. Jill bought two tacos and one burrito and paid $3.10.
What is the individual cost of a taco? How much does a burrito cost?
(How do I write my two equations for this?? Pls and thank you!)
answer:
x = 0.80
y = 1.50
step-by-step explanation:
x = cost of tacos
y = cost of burritos
both equations:
3x + 2y = 5.40
2x + 1y = 3.10
^
turn this | into this |
v
y = 3.10 - 2x
then add it to the equation :
3x + 2 [ 3.10 - 2x ] = 5.40
3x + 6.2 - 4x = 5.40
-1x = - 0.8
x= 0.80
then add x = 0.80 to the equations to get :
3 [ 0.80 ] + 2y = 5.40
2.4 + 2y = 5.40
2y = 3
y = 1.5

Which equation represents f(x)? f(x) = RootIndex 3 StartRoot x + 6 EndRoot + 1 f(x) = RootIndex 3 StartRoot x minus 6 EndRoot + 1 f(x) = RootIndex 3 StartRoot x + 6 EndRoot minus 1 f(x) = RootIndex 3 StartRoot x minus 6 EndRoot minus 1
Answer:
A.
Step-by-step explanation:
The equation that represents function f(x) is (a) [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
The original function is given as:
[tex]y = \sqrt[3]{x}[/tex]
First, the function is translated 6 units left.
The rule of this translation is:
[tex](x,y) \to (x +6,y)[/tex]
So, we have:
[tex]y = \sqrt[3]{x + 6}[/tex]
Next, the function is translated 1 unit up.
The rule of this translation is:
[tex](x,y) \to (x,y+1)[/tex]
So, we have:
[tex]y = \sqrt[3]{x + 6} + 1[/tex]
Express y as a function of x
[tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
Hence, the equation that represents f(x) is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

What is the value of 10 - 2(
4-5)?
Answer:
12
Step-by-step explanation:
you would need to use BODMAS to work this out
as a result you would work out the value in the brackets which would equal to -1 so the question would look like this: 10-2(-1)
next you would do the multiplication due to the fact it comes next in the order
so you would end up with 10+2 which would equal to 12
Hope this helps
Answer:
12
Step-by-step explanation:
First we do 4-5 because of Order of Operations. So we get -1
Then we do multiplication because of Order of Operations and we get -2*-1=2
So now we do 10+2 and we get 12.
You may be asking why I did -2*-1.
It honestly doesn't matter.
Let's say I did 2*-1. We get -2.
Then we do 10-(-2) and If you subtract a negative, it's just adding basically. So we can put it as 10+2 and we get 12.

Is y=x+3.75 a proportional relationship? Yes or no
Answer:
NO
Step-by-step explanation:
if we plug in 1 = x, we get 4.75 = y. If this is proportional, then y/x will be the same in each scenario.
Let's plug in 2 = x to get y = 5.75. 5.75/2 = 2.875 DOES NOT EQUAL 4.75/1 = 4.75.
That means that the relationship is NOT proportional.
The easier way to tell is to see that there is a number being added, so it can't be a proportional relationship.
Answer:
No
Step-by-step explanation:
because if we put x=1 in equation y=x+3.75y=(1)+3.75y/x=4.75if that is proportional then y/x will be same in each scenarioand if we put x=2 then y=(2)+3.75y=5.27y/x=2.875so it is not equal, it mean that relation is not proportionalJanice bought 5.5 m of fabric.

Greg drove 300 miles at a constant speed in 5. The speed limit was 70 miles per hour. Was his rate greater than the speed limit?
The average speed of Greg will be 60 miles per hour.
To answer this question, we need to calculate Greg's average speed during the trip.
We can use the formula:
Average Speed = Total Distance / Total Time
In this case, Greg drove 300 miles in 5 hours, so:
Average Speed = 300 miles / 5 hours = 60 miles per hour
Since Greg's average speed was 60 miles per hour, which is less than the speed limit of 70 miles per hour, his rate was not greater than the speed limit.

Henry predicted whether he got answers right or wrong in his 50 question exam. He identified the 36 questions he thought he got right. It turns out that Henry got 5 questions wrong that he thought he got correct and he only got 11 of the questions wrong he had predicted. What is the percentage accuracy he had with predicting his scores?
Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%

A recipe for orange water says, "Mix 3 teaspoons yellow water with 1 teaspoon red water." For this recipe, we might say: "The ratio of teaspoons of yellow water to teaspoons of red water is 3:1 ." Write a ratio for 2 batches of this recipe and explain how you know it is equivalent to 3:1.
Answer:
The ratio of 2 batches of recipe is 6:2. Which is equivalent to 3:1 because if we multiply the ratio with same number it would give us equivalent ratio.
Step-by-step explanation:
When mix 3 teaspoon of Yellow water with 1 teaspoon of red water, we get ratio as 3:1
If we use 2 batches of recipe, the ratio is multiplied twice.
That's ratio of yellow water to red water is 3*2 :1*2 , which gives 6:2

Segment bisector is the line in half
The segment bisector of MN is JK and the measure of MN is 52.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The only bisector of MN is JK and it is at the midpoint of the line segment MN so it will be a bisector.
Now,
Since JK is the bisector of MN
M(JK) = (JK)N
26 = (JK)N
So,
MN = 2(26) = 52

A stadium has 55,000 seats. Seats sell for $42 in Section A, $24 in Section B, and $18 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,738,800 from each sold-out event. How many seats does each section hold?
Answer:
Section A = 27,500 seats
Section B = 14,800 seats
Section C = 12,700 seats
Step-by-step explanation:
Section A = $42
Section B = $24
Section C = $18
Revenue = $1,738,800
Total number of seats = 55,000
The number of seats in Section A equals the total number of seats in Sections B and C
A = B + C
A + B + C = 55,000
42A + 24B + 18C = $1,738,800
Substitute A = B + C into the equations
B + C + B + C = 55,000
42(B + C) + 24B + 18C = $1,738,800
2B + 2C = 55,000
42B + 42C + 24B + 18C = 1,738,800
2B + 2C = 55,000
66B + 60C = 1,738,800
Multiply (1) by 30
60B + 60C = 1,650,000. (1)
66B + 60C = 1,738,800. (2)
Subtract (1) from (2)
66B - 60B = 1,738,800 - 1,650,000
6B = 88,800
B = 88,800/6
= 14,800
B = 14,800
Substitute the value of B into
2B + 2C = 55,000
2(14,800) + 2C = 55,000
29,600 + 2C = 55,000
2C = 55,000 - 29,600
2C = 25,400
C = 25,400/2
= 12,700
C = 12,700
Substitute the values of B and 6 into
A + B + C = 55,000
A + 14,800 + 12,700 = 55,000
A + 27,500 = 55,000
A = 55,000 - 27,500
= 27,500
A = 27,500
Section A = 27,500 seats
Section B = 14,800 seats
Section C = 12,700 seats
Answer:
Section A has 27,500 seats
Section B has 14,800 seats
Section C has 12,700 seats
Step-by-step explanation:
To solve this, we will have equations:
let x = seats at section A
y= seats at section B
Z = seats at section C
we will get the following equation:
So from the question, x = y + z ..........(1)
x + y + z = 55,000 .........(2)
42x + 24y + 18z = 1,738,800 .... (3)
input equation (1) into (2)
y + z + y + z = 55,000
2y + 2z = 55,000...... (4)
so for exuation (3), input equation (1) into (3):
42x + 24y + 18z = 1,738,800
42(y + z) + 24y + 18z = 1,738,800
42y + 42z + 24y + 18z = 1,738,800
collect like terms:
66y + 60z = 1,738,800 ..... (5)
multiply equation (4) by -30. -30 is chosen to remove z from the equation so we could get what y is
-60y - 60z = - 1,650,000 ...... (6)
add equation (5) and (6)
6y + 0 = 88,800
y = 14,800 seats
Input the value of y into equation (4) to find z
2y + 2z = 55,000
2(14,800) + 2z = 55,000
29,600 + 2z = 55,000
2z = 25,400
z = 12,700 seats
To find the number of seats in section A we use equation (2)
x + y + z = 55,000
x +14,800 + 12,700 = 55,000
x + 27,500 = 55,000
x = 27,500 seats
To verify our answer to see if the number of seats in Section A equals the total number of seats in Sections B and C.
total number of seats in Sections B and C = 14,800 + 12,700 = 27,500
so number of seats in section A = B + C
