Answer:
y = 14x + 10
Step-by-step explanation:
We are given two points, (x, y) = {(5, 80), (3, 52)}. The 2-point form of the equation for a line can be used to find the equation.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (52 -80)/(3 -5)(x -5) +80 . . . . . fill in the given values
y = (-28/-2)(x -5) +80 . . . . . simplify a bit
y = 14x -70 +80 . . . . . eliminate parentheses; next, collect terms
y = 14x +10
A hotel puts out 1 apple for every 3 orange as the fruit for their breakfast buffet. Write a ratio of apples compared to all the fruit. *
Answer:
1:4
Step-by-step explanation:
In the ratio:
Number of apples: 1
Number of oranges: 3
Total number of pieces of fruit: 3 + 1 = 4
apples : all fruit = 1:4
Answer: 1:4
The ratio of apples compared to all the fruit will be 1: 4.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
A hotel puts out 1 apple for every 3 oranges as the fruit for their breakfast buffet.
The ratio of apples compared to all the fruit will be given as,
Apple: Fruits = 1: (3 + 1)
Apple: Fruits = 1: 4

Happy Holidays! =)
[tex]\large\boxed{x = -\frac{5}{2} \text{ and } 1}}[/tex]
4x² + 6x = 10
Move 10 to the other side so we can factor the trinomial:
4x² + 6x - 10 = 0
Factor the GCF, or 2 out of the equation:
2(2x² + 3x - 5) = 0
Factor the terms inside of the parenthesis:
2(2x + 5)(x - 1) = 0
Disregard the coefficient of 2 and set each factor equal to 0:
2x + 5 = 0
2x = -5
x = -5/2
x - 1 = 0
x = 1
The values of x are -5/2 and 1.

Answer:
x=3.333 or 10/3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x-(2*(-6*x+18)+14)=0
Pull out like factors :
-6x + 18 = -6 • (x - 3)
to make 3x - (-12 • (x - 3) + 14) = 0
Pull out like factors :
15x - 50 = 5 • (3x - 10) to get
5 • (3x - 10) = 0
Solve : 3x-10 = 0
Add 10 to both sides of the equation :
3x = 10
Divide both sides of the equation by 3:
x = 10/3 = 3.333
Answer:
f
Step-by-step explanation:
substitue the y
3x=2(-6x+18)+14
distrubute
3x=-12x+36+14
combine like terms
3x=-12x+50
add -12x on both sides
15x=50
divide 15 on both sides
x=50/15
simplify
x=10/3

Find three consecutive even integers such that the sum of the second and third is 3 times the first integer.
Answer:
[tex]6[/tex], [tex]8[/tex] and [tex]10[/tex]
Step-by-step explanation:
Let [tex]x =[/tex] smallest consecutive even integer.
Since the second and third consecutive even integers can be expressed by our smallest even consecutive integer, we can express them as:
Second consecutive even integer = [tex]x+2[/tex]
Third consecutive even integer = [tex]x+4[/tex]
From "the sum of the second and third is 3 times the first integer", we can write:
[tex]x+2+x+4 = 3x[/tex]
[tex]2x+6 = 3x[/tex] (collect like-terms)
[tex]x=6[/tex]
∴ The first consecutive even integer is 6
Now, we can use substitution to find the values of the second and third consecutive even integers:
Second consecutive integer = [tex]x+2[/tex]
[tex]=6+2[/tex]
[tex]=8[/tex]
Third consecutive integer = [tex]x+4[/tex]
[tex]=6+4[/tex]
[tex]=10[/tex]
∴ The three consecutive even integers are [tex]6[/tex], [tex]8[/tex] and [tex]10[/tex].

Tanya is at a fair and has $30 to spend on x number of rides and y number of games. Each ride is $2 and each game is $3. The equation 2x+3y=30 represents this scenario. If Tanya does not play any games, how many rides can she go on?
Answer:
15 rides
Step-by-step explanation:
From the above Question we know that if Tanya goes on a ride, the Algebraic expression = 2x
Where x = number of rides
If Tanya does not play any games, how many rides can she go on?
Note that: Tanya has $30 to spend
This question is solved:
2x = $30
x = $30/2
x = 15 rides
Hence, if Tanya does not play any games she can go on 15 rides

Minnie is making tea. She knows that her tea tastes best if she lets her tea bag sit in the hot water for exactly fifteen minutes. However, depending how hot the water is, she may have to leave her tea bag in the water for 2 minutes more or less than usual. Write and solve an absolute value equation to describe this situation
Answer:
|x - 2| = 15 ; |x + 2| = 15
Step-by-step explanation:
Given that:
Wait time = 15 minutes
Variation in wait time depending on level of hotness = 2 minutes
X ± 2 = 15
x + 2 = 15 or x - 2 = 15
x = 15 - 2 = 13 or x = 15 + 2 = 17
Hence, to express the above as an absolute value equation :
|x - variation| = mean time
|x - 2| = 15 ; |x + 2| = 15
Put the following equation of a line into slope-intercept form, simplifying all
fractions.
6x – 15y = 135
Answer:
Step-by-step explanation:
Slope-intercept form means the equation of a line should be in this form:
[tex]y=mx+b[/tex]
So we re-write our equation into this form like this:
[tex]6x-15y=135\\-15y=-6x+135\\y=\frac{-6x+135}{-15} \\\\y=\frac{-6x}{-15}+\frac{135}{-15} \\\\y=\frac{2}{5}x-9 \\[/tex]

Select the correct locations on the graph
select the lines that represent functions
Step-by-step explanation:
Using the vertical line test, we can see which lines are functions, and which are not. If a vertical line were to hypothetically appear, would it touch more than one part of the line? If so, it is not a function.
The lines outlined in a black box are the correct answers.

Step-by-step explanation:
A plumber charges a flat fee of $50 plus an additional $20 per hour.
a) Write and equation in slope-intercept form to represent the total cost the plumber will charge
b) How much will it cost for the plumber to work for 4 hours
c) how many hours must the plumber work to obtain $180?
Answer:
a) cost = 50 + 20x, where x is the number of hours worked for.
plot cost on the y-axis and hours on the x-axis.
b) cost = 50 + 20 x 4 = $130
c) 180 = 50 + 20x
130 = 20x
6.5 = x
additional charges increment every hour, so the plumber must work for 7 hours before they obtain $180.
Step-by-step explanation:
which expression is equivalent to
2(3g-4)-(8g+3)?
-2g-1
-2g-5
-2g-7
-2g-11
Answer:
-2g - 11
Step-by-step explanation:
Expand the brackets, multiply 2 over 3g and -4. One plus and one minus make a minus.
2(3g-4) - (8g+3) = 6g - 8 - 8g - 3
Evaluate like terms.
6g - 8 - 8g - 3 = -2g - 11
A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth
Answer:
h= -20
t = -0.104 and -2.39s
Step-by-step explanation:
A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth
The velocity of the body at its maximum height is zero
V= dh/dt
dh/dt = 32t + 40
0 = 32t+40
-32t = 40
t = 40/-32
t = -1.25s
Substitute t = -1.25 into the expression
h(t)=16t^2+40t+4.
h(-1.25)=16(-1.25)^2+40(-1.25)t+4.
h = 16(1.5625)-50+5
h = 25-45
h =-20
Hence the maximums height is -20m
The ball will reach the ground at h = 0
Substitute
h(t)=16t^2+40t+4.
0 = 16t^2+40t+4
Divide through by 4
0 = 4t²+10t+1
Factorize
-10±√10²-4(4)/2(4)
t = -10±√100-16/8
t = -10±√84/8
t =-10+9.17/8
t = -0.83/8 and -19.17/8
t = -0.104 and -2.39s
