Jamie’s car is getting repaired. It costs $40 an hour and an extra fee of $225 for parts. Which expression represents Jamie’s costs to repair her car?
265 + h
225h + 40
40h + 225
225h + 40h
Multiply the price per hour by number of hours and then add the fee for the parts.
The answer would be 40h + 225

Match each diagram with a description and an equation.
Graphs such as line and tape diagrams can be used to represent equations.
The equation of the first diagram is y = 0.6x,and it represents a decrease by 0.4 or 2/5The equation of the second diagram is y = 1.83x,and it represents an increase of 5/11 or 0.83Diagram (a)
In this diagram, all the x boxes (5 boxes) are shaded, while all the y boxes (3) are shaded.
So, the equation is:
[tex]y = \frac{3}{5}x[/tex]
Express as decimal
[tex]y = 0.6x[/tex]
The ratio (0.6) is less than 1.
So, it represents a decrement.
And the decrement (d) is:
[tex]d = 1 - 0.6[/tex]
[tex]d =0.4[/tex]
Diagram (b)
In this diagram, all the x boxes (6 boxes) are shaded, while part of the y boxes (6 of the 11) are shaded.
So, the equation is:
[tex]y = \frac{11}{6}x[/tex]
Express as decimal
[tex]y = 1.83x[/tex]
The ratio (1.83) is greater than 1.
So, it represents an increment.
And the increment (d) is:
[tex]d = 1.83 - 1[/tex]
[tex]d = 0.83[/tex]

Answer:576
Step-by-step explanation:
Write an equation that relates the number of tennis balls (y), with the number of cans (x). (Do not put spaces between numbers, variables, and operations)
Answer:
y = 3x
Step-by-step explanation:
Since, line given in the graph passes through origin (0, 0), relation between the number of tennis balls (y) and the number of cans (x) will be proportional.
y ∝ x
y = kx
Here 'k' = proportionality constant
Since the given line is passing through (1, 3),
3 = k(1)
k = 3
Therefore, equation of the line will be,
y = 3x

An incomplete proof of 1- tanθcosθ/cscθ=cos^2 θ is shown.
Which of the following expressions could be used to complete the second step of the proof?
It's the fourth option, 1 - sinθ/cscθ. This is due to the cancellation of cosθ in the numerator:
1 - (sinθ/cosθ × cosθ)/cscθ = 1 - sinθ/cscθ

A summer camp counselor wants to
calculate a length, x, in feet, across a pond
as represented in the sketch. Segments AC
and DE intersect at B, and AEB and CDB
have the same measure. What is the distance
across the pond? Round to the nearest
hundredth.
Answer: 1600
Explanation: If angles E and D are the same with the lines intersecting at B, then that means that A and C are also the same, as the opposite angles formed at point B are also the same, so you have two similar triangles.
Similar triangles have proportional lengths. So we know length CD is 800 ft and its similar leg on the other side (AE) is unknown.
So we need to find two known lengths, one on the large and one on the small, that are similar.
BE is 1400 ft and BD is 700 ft. Those are you two known similar legs. So now we can use them in a proportion to find AE.
We will do the line ending at B over the line that doesn't include B.
Large triangle:
x
1400
Small triangle:
800
700
Set them up in a proportion:
x
1400
=
800
700
Solve for x:
⇒7x=11200
⇒x=1600 ft

Answer:
A. Rectangle
Step-by-step explanation:
Shown in the attachment are the four points graphed on a coordinate plane.
We can see that the opposite sides are parallel to each other and have the same length.
The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.
The answer cannot be C. Rhombus because of the same reason as above.
The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.
Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.
Using the diagram below determine which statement is NOT true.
Answer:
A

Explain how to write x^2+5x+6 as the product of two linear factors. Use complete English and math sentences.
Answer:
(x + 3)(x + 2)
Step-by-step explanation:
Given
x² + 5x + 6
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 3 and + 2 , since
3 × 2 = + 6 and + 3 + 2 = + 5 , then
x² + 5x + 6 = (x + 3)(x + 2) ← in factored form
