A)4x + y = - 4
B)4x - y = - 4
C)-4x - y = 4
D)-4x + y = - 4
Answer:
4x+y=-4
Step-by-step explanation:
gradient(m)=y2-y1/x2-x1
the line also passes through points (x,y) and (-2,4)
-4=4-y/-2-x
cross multiplying
8+4x=4-y
option(A):4x+y=-4

450/15 = 30
so the car can travel 30 miles per gallon
18*30 = 540
Answer:
540 miles
Step-by-step explanation:
Gallons: 15 18
Miles: 450 x
450 divided by 15 = 30
18 times 30 = 540

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (12, 5); m = -3
Answer:
y - 5 = -3(x - 12)
Step-by-step explanation:
Point slope form is: y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
Plug in the point and the slope:
y - y1 = m(x - x1)
y - 5 = -3(x - 12)
So, y - 5 = -3(x - 12) is the equation in point slope form of the line.
Answer:
y-5 = -3(x-12)

What is Highest Common Factor?The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one.
For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.
Given:
264627 and 305613
Now, prime factorizing both number
264627 = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 11 x 11
and, 305613 = 3 x 3 x 3 x 3 x 7 x 7 x 7 x 11

A fire hydrant is 30 in. tall and casts a shadow 8 in. long. how tall is a
nearby tree that casts a shadow 4 ft long?
Using proportions, it is found that a tree that casts a shadow 4 ft long is 180 in. tall.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a fire hydrant that is 30 in. tall and casts a shadow 8 in. long. We want to find the height of a tree that casts a shadow of 4 ft = 4 x 12 = 48 inches. Hence, the rule of three is given by:
30 in - 8 in
h in - 48 in
Applying cross multiplication:
h = 48 x 30/8
h = 6 x 30.
h = 180 in.

Write a proof for the biconditional using the conditional and converse.
A triangle is equilateral if and only if all the side lengths of the triangle are equal.
Answer: see below
Step-by-step explanation:
Hypothesis (p): A triangle is equilateral
Conclusion (q): The side lengths are equal
Conditional (p → q): If a triangle is equilateral, then its side lengths are equal.
The conditional statement is TRUE
Converse (q → p): If the side lengths of a triangle are equal, then it is equilateral.
The converse statement is TRUE
Since p → q and q → p are both TRUE, then it is biconditional.

What are the consecutive numbers?The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.
Given that the sum of 3 consecutive integers is 48.
We need to find the smallest of the integers.
Let assume the 3 consecutive integers are x, (x+1) and (x+2)

Answer:
u ≈ 5.7
Step-by-step explanation:
Using the Sine rule in Δ TUV, that is
[tex]\frac{t}{sinT}[/tex] = [tex]\frac{u}{sinU}[/tex] , substitute values
[tex]\frac{2.5}{sin26}[/tex] = [tex]\frac{u}{sin85}[/tex] ( cross- multiply )
u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )
u = [tex]\frac{2.5sin85}{sin26}[/tex] ≈ 5.7 ( to 1 dec. place )
A clothing store owner decided to track customers' reasons for returning items. She found that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item and 4% changed their mind about the purchase. The remaining customers returns gifts purchased for them. What is the probability that out of 40 returns on a given day, 20 are gifts that are being returned?
Answer:
0.102542
Step-by-step explanation:
Given that 9% of customers do not provide a reason, 29% say the item did not fit, 13% find a flaw with the item, and 4% changed their mind about the purchase.
So, the total percentage of items returned due to no reason, unfit, flaw, and due to changing mind
=9%+29%+13%+4%=55%
As the remaining customers returned gifts purchased for them, so, the percentage of customers who returned gifts =100-55=45%.
So, the fraction of customers who returned gifts=45/100=0.45.
Now, observe that if 1 item returned, there is a chance of 0.45 that the item is a gift.
Moreover, there are only two possibilities for any idem, i.e the idem was a gift or not a gift, so the number of total returned items can be considered a Bernoulli's population.
Let p be the probability of a returned item which is the same for all the returned items,
p=0.45
So, according to Bernoulli's theorem, the probability that out of n=40 returns on a given day, r=20 are gifts is
[tex]\binom{n}{r}p^r(1-p)^{n-r}=\binom{40}{20}(0.45)^{20}(1-0.45)^{40-20}[/tex]
[tex]=0.102542[/tex]
Hence, the probability that 20 returned items are gifts among the total 40 returned items is 0.102542.

If 1 foot ≈ 0.305 meter, approximately how many feet are in 8 meters? Round to the nearest tenth, if necessary.
Answer:
26.22 foot
Step-by-step explanation:
The relation between foot and meter is given by :
1 foot = 0.305 meter
We firstly find value of 1 meter in terms of foot.
So,
[tex]1\ m=\dfrac{1}{0.305 }\ \text{foot}[/tex]
To find no of foot in 8 meters, multiply [tex]\dfrac{1}{0.305 }[/tex] by 8 i.e.
[tex]8\ m=\dfrac{1}{0.305 }\times 8\ m\\\\=26.22\ \text{foot}[/tex]
So, there are 26.22 foot in 8 meters.

please mark me as brainlest
Answer: 32
Step-by-step explanation:
This is an example of an arithmetic sequence as the difference between the first 3 terms is constant. We can see that 4 is constantly being subtracted.
[tex]a_{n}=a+(n-1)d[/tex] is the formula for an arithmetic sequence.
[tex]a_{n}[/tex] = nth term
a = the first term in the sequence
n = term you are looking for (in this case 45)
d = common difference between the terms (in this case -4)
∴
[tex]a_{n}=a+(n-1)d[/tex]
[tex]a_{45} =208+(45-1)(-4)\\a_{45}=32[/tex]
What is the value of z?
Answer: 58 degrees
Step-by-step explanation:
We can see that this triangle is an isosceles triangle so that means the two bottoms angles will be equal
Point S must be equal to point U
z = 58 degrees
Check if this is true:
Angle sum of a triangle: 180 degrees
58 + 58 = 116
180 - 116 = 64
Point T is 64
58 + 58 + 64 = 180

D
The triangle represents delta notation change in y over change in x. the correct option is C.
What is the rate of change?The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another.
The average rate of change is calculated by the formula,
Rate of change = Δy / Δx
Here, the triangle represents the rate of change of the y coordinate with respect to the rate of change of the x coordinate.

Answer:
B both are proportional
Step-by-step explanation:
so i think by proportional its linear?
so the graph is linear because its a line and its a function, but for the table we first have to find the slope by using the equation
y2 - y1 / x2 - x1
(4, 1.31) and (8, 2.62) will be the points we will use
2.62 - 1.31 / 8 - 4
1.31/4
0.3275x
now i think we use a point we did not use yet sooo (16, 5.24)
we substitute
y = 0.3275x + b
5.24 = 0.3275(16) + b
5.24 = 5.24 + b
b = 0
so the equation would be
y = 0.3275x
now we check with the last point given
6.55 = 0.3275(20) ?
6.55 = 6.55
so i think the answer is both are proportional ?
