The perimeter of rectangle WXYZ is 34 inches. A scale factor of 1.75 is used to dilate rectangle WXYZ to rectangle ABCD. What is the perimeter of rectangle ABCD?
Answer:
59.5 units
Step-by-step explanation:
A rectangle is a quadrilateral (has four side) in which opposite sides are parallel and the diagonals bisect each other. The perimeter of a rectangle is:
Perimeter = 2(length + breadth) = 2(l + b)
The perimeter of rectangle WXYZ is 34 inches. Therefore:
34 = 2(l + b)
l + b = 17
Rectangle ABCD is formed by dilating rectangle WXYZ by a scale factor of 1.75. Let l' = length of ABCD and b' = breadth of ABCD hence:
Length of ABCD = l' = 1.75l
Breadth of ABCD = b' = 1.75b
Perimeter of ABCD = 2(l' + b') = 2(1.75l + 1.75b) = 2(1.75)(l + b) = 3.5(l + b)
Perimeter of ABCD = 3.5(17) = 59.5 units

A student is working two jobs over the summer to pay for a new car. The student gets paid $25 for each lawn that
is mowed (C)and $15 for each pool that is cleaned (y). The student wants to earn $750 to pay for a down payment
on a car.
• Create a model in standard form to represent this linear relationship.
• Identify the x-intercept. Explain what this means in the context of the problem.
• Identify the y-intercept. Explain what this means in the context of the problem.
Identify two combinations that are solutions to this equation. Explain what these combinations mean in the
context of the problem.
Answer:
Step-by-step explanation:
- 25x + 15y = 750
- (30, 0) are coordinates of x-intercept. If there is no pool-cleaning job student has to do 30 lawn-mowing.
- (0, 50) are coordinates of y-intercept. If there is no lawn-mowing job student has to do 50 pool-cleanings.
- ( 15 , 25 ) mean 15 lawn-mowing and 25 pool-cleanings
$25(15) + $15(25) = $750
$375 + $375 = $750

Write the equation in point-slope form for the line that passes through the given point and has the given slope. (1, 2), slope 3
Answer:
y-y1 = m(x-x1)
y - 2 = 3(x-1)
y=3x-3+2
y=3x-1
Step-by-step explanation:
first you type down point slope formula
then you plug in the information you have point (1,2) 1 is x1 and 2 is y1 m is 3 because m = slope
then you have to distribute the 3 to the x and the -1 and then isolate y
(how to isolate the y) you must do the opposite of -2 which is +2 whatever you do on one side you have to do to the other
then you combine like terms 3x is alone and -3 +2 equals -1
there is your answer hope that works.
find the zeros of the polynomial x square-3 and verify the reationship between the zeros and the coefficient.
Answer:
√3, and -√3
Step-by-step explanation:
to find the zeros or roots of the polinomial x²-3 make it equal to zero and solve for x
x²-3=0 add 3 to both sides to isolate x
x² = 3 squareroot both sides
√x²= √3
x= ±√3 are the two zeros

Answer:
6.75 miles
Step-by-step explanation:
First, you need to find the unit rate by dividing 27/2. This equals 13.5. Then, multiply this by 1/2 to get 6.75 miles.

Suppose a bird is 500 feet above the ground. It descends at a steady rate. After 10 seconds, it is 250 feet above the ground.
a) Write an equation that gives the height of the bird as a function of time. Be sure to define your variables!
b) After how many seconds will the bird land on the ground?
Answer:
500-10x=250
x=how much the bird descended in a second
the bird will land on the ground in another 10 seconds.
Step-by-step explanation:
the bird will land on the ground in 10 seconds since it descended 250 ft in 10 seconds so that is 25 ft per second. then do 250/25 and you get 10. that is how you know the bird will land on the ground in 10 seconds.
Answer:
a) [tex]h(t)=500-25t[/tex]
b) [tex]t=20[/tex]
Step-by-step explanation:
a)
Let [tex]h[/tex] = height above ground
Let [tex]t[/tex] = time
Because the bird descended down to 250 feet in 10 seconds with a steady rate, that means it descends 25 feet per second.
∴ [tex]h(t) = 500-25t[/tex]
b)
To find the time it takes until the bird reaches the ground, [tex]h[/tex] must equal [tex]0[/tex]:
[tex]0=500-25t[/tex]
[tex]25t=500[/tex]
[tex]t=20[/tex]
∴ It takes 20 seconds for the bird to reach the ground.

(-2,8), (r, 4), m =-1/2
Answer:
[tex]r=6[/tex]
Step-by-step explanation:
Make an equation in point-slope form where:
the equation is [tex]y-y_{1}=m(x-x_{1})[/tex]m is the slopey1 and x1 are the corresponding coordinate points [tex](x_{1},y_{1})[/tex]Insert the known values:
[tex](-2_{x1},8_{y1})\\\\m=-\frac{1}{2} \\\\y-8=-\frac{1}{2} (x-(-2))\\\\y-8=-\frac{1}{2} (x+2)[/tex]
Use the distributive property:
[tex]-\frac{1}{2} (x+2)\\\\-\frac{1}{2}(x)-\frac{1}{2}(2)[/tex]
Simplify. Turn the 2 into a fraction by converting to the fraction [tex]\frac{2}{1}[/tex] , which is still equal to 2:
[tex]-\frac{1}{2}(2)\\\\-\frac{1}{2}*\frac{2}{1}[/tex]
Multiply across:
[tex]-\frac{1}{2}*\frac{2}{1} =-\frac{2}{2} =-1[/tex]
Re-insert into the equation:
[tex]y-8=-\frac{1}{2}x-1[/tex]
Solve for y. Add 8 to both sides (to isolate y using inverse operations):
[tex]y-8+8=-\frac{1}{2}x-1+8\\\\y=-\frac{1}{2}x+7[/tex]
Now insert the y value of the other point to find r (which will have the same value as x):
[tex](r_{x},4_{y})\\\\4=-\frac{1}{2}x+7[/tex]
Simplify the fraction by multiplying. Add 1 as the denominator for x:
[tex]-\frac{1}{2}*\frac{x}{1}[/tex]
Multiply across:
[tex]-\frac{1}{2}*\frac{x}{1}=-\frac{x}{2}[/tex]
Re-insert:
[tex]4=-\frac{x}{2} +7[/tex]
Subtract 7 from both sides (to isolate the variable using inverse operations):
[tex]4-7=-\frac{x}{2} +7-7\\\\-3=-\frac{x}{2}[/tex]
Multiply both sides by 2 (to undo the fraction using inverse operations):
[tex]2(-3)=2(-\frac{x}{2}) \\\\-6=-x[/tex]
Divide both sides by -1 (to make the variable positive, since two negatives make a positive):
[tex]\frac{-6}{-1} =\frac{-x}{-1} \\\\x=6[/tex]
Therefore, the value of r is 6.

Which is correctly written in standard form of y=-6/7x+12
Answer:
6x + 7y +84
Step-by-step explanation:
The linear equation y = -(6/7) x + 12 in the standard form will be 6x + 7y - 84 = 0.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation in standard form is given as,
ax + by + c = 0
Where -a/b is the slope of the line and c/b is the y-intercept of the line.
The linear equation in slope-intercept form is given below.
y = -(6/7)x + 12
Convert the equation into a standard form. Then we have
y = -(6/7)x + 12
y = (-6x + 84) / 7
7y = - 6x + 84
6x + 7y - 84 = 0
The linear equation y = -(6/7) x + 12 in the standard form will be 6x + 7y - 84 = 0.

Answer:
Each smoothie was $4.5.
Step-by-step explanation:
We know that he has $50 to use, and after he used it he had $14 left. That means he used $36.

Over which interval does g have a negative average rate of change? Please answer ASAP!
Answer:
b
Step-by-step explanation:
when x is -2, y is 7
when x is -1, y is 5
we can see y is decreasing and it continues to decrease until x is 3
The average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that:
A function g(x) is shown in the table.
As we know the average rate of change of a function can be given:
The average rate of change = change in y values/change in x values
For the interval [1, 5]
The average rate of change = (2-0)/(5-1) = 2/4 = 1/2
For the interval [-2, 3]
The average rate of change = (-5-7)/(3+2) = -12/5
For the interval [-5, 0]
The average rate of change = (3-0)/(0+5) = 3/5
For the interval [-4, -1]
The average rate of change = (5-2)/(-1+4) = 3/3 = 1
Thus, the average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.
