Answer:
y=9x+75
Step-by-step explanation:
since we know that the slope must be the same for two lines to be proportional, we are gonna start there.
so our equation is: y= 9x + b
we need to find b to complete our equation, so substitute in the points we were given.
3 = 9(-8) + b
so now,
3 = -72 + b
now we have to isolate b to find out what it is,
3 = -72 + b
+72 +72
so now: 75= b
Put that back into the starting equation: y = 9x + 75
Keenan buys an embroidery machine for $1,400. He uses it to embroider T-shirts. His total profit in dollars from selling the T-shirts is represented with the function f(x) = 12x − 1,400. When the machine breaks, he pays $135 to have it fixed. How does that cost affect a graph of Keenan’s profit function?
Answer:
the graph shift down 135 units
Step-by-step explanation:
when there is no fixing cost:
f(x)=12x-1400
when there is fixing cost (0ne time): 12x-(1400+135)
the graph shift down 135 units

Multiplying a measure
by a scale to produce a
reduced or enlarged
measure
Answer:
we conclude that:
If the scale factor > 1, the image is stretchedIf the scale factor < 1, the image is reducedIf the scale factor = 1, the image and object will be congruentStep-by-step explanation:
A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.
The image can be obtained by multiplying the measure of the original object by a scale factor.
If the scale factor > 1, the image is stretched
If the scale factor < 1, the image is reduced
If the scale factor = 1, the image and object will be congruent
For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.
Dilation with scale factor 2, multiply by 2.
(x, y) → (2x, 2y)A(2, 2) → (2(2), 2(2)) = A'(4, 4)
So, the image point A'(4, 4) is enlarged.
Dilation with scale factor ½, multiply by ½.
(x, y) → (½x, ½y )A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)
So, the image point A'(1, 1) is reduced.
Therefore, we conclude that:
If the scale factor > 1, the image is stretchedIf the scale factor < 1, the image is reducedIf the scale factor = 1, the image and object will be congruentworking on a song for someone I used to love

What is an equation of the line that passes through the points (-3, 8) and (4, 1)?
Answer:
The equation of the line is:
[tex]y=-x+5[/tex]
Step-by-step explanation:
Given the points
(-3, 8)(4, 1)Finding the slope between the points
[tex]\left(x_1,\:y_1\right)=\left(-3,\:8\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{1-8}{4-\left(-3\right)}[/tex]
[tex]m=-1[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = -1 and the point (-3, 8)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-1\cdot \left(x-\left(-3\right)\right)[/tex]
[tex]y-8=-\left(x+3\right)[/tex]
Add 8 to both sides
[tex]y-8+8=-\left(x+3\right)+8[/tex]
[tex]y=-x+5[/tex]
Therefore, the equation of the line is:
[tex]y=-x+5[/tex]

Solve by factoring. Check your answer.
[tex]x^2-4x=0[/tex]
Please show all your work and explain all steps. Thanks :)
Answer:
[tex]x=0,4[/tex]
Step-by-step explanation:
Factor out the common terms from the given terms:
[tex]x^2-4x=0[/tex]
You can factor out x from both:
[tex]x(x-4)=0[/tex]
Rewrite, setting each equal to 0:
[tex](x)(x-4)=0\\\\x=0\\\\x-4=0[/tex]
Simplify the second equation by solving for x:
[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]
Therefore, x=0 or x=4

1.) Select the correct equation for the following situation. Mariana had 134
crystals in her collection. This was 38 less than Rajesh's collection. How
many crystals are in Rajesh's collection?
38r = 134
r+ 38 = 134
r - 38 = 134
38 - r = 134
Answer:
r minus 38 equals to 134 this might be m not certain
The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .
Let us consider that, Rajesh had r crystals.
Mariana had 134 crystals in her collection.
Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.
So, [tex]r-38=134[/tex]
Now, find crystals present in Rajesh collection.
[tex]r-38=134\\\\r=134+38=172[/tex]
Thus, Rajesh have 172 crystals .

for a given input value of n, the function h outputs a value of m to satisfy the following equation.
m+1=-2(n+6)
write a formula for h (n) in terms of n
h(n)=
Answer:
h(n) = - 2n - 13
Step-by-step explanation:
Given
m + 1 = - 2( n + 6) = - 2n - 12 ( subtract 1 from both sides )
m = - 2n - 13, that is
h(n) = - 2n - 13

If m_ABD = 64°, and mZCBD = 30°,
then m ABC = [?]°
Answer:
34 degrees
Step-by-step explanation:
If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)
Step 1.CBD + ABC = ABD
Step 2. Substitute
30 + ABC = 64
Step 3. Isolate ABC
34 = ABC
ABC is 34 degrees
9514 1404 393
Answer:
34°
Step-by-step explanation:
It should be fairly intuitive that the two smaller angles add to give the value of the larger one. (Even if it's not, the angle sum theorem tells you this is true.)
∠ABC + ∠CBD = ∠ABD
∠ABC + 30° = 64°
∠ABC = 34° . . . . . . . . . subtract 30° from both sides of the equation

The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers. Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see. As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger. Again, this is true for all + or - parabolas. ....... Can consider brainlist*:)

–24 + 12d = 2(d – 3) + 22
Answer:
d = 4
Step-by-step explanation:
Answer:
d = 4
Step-by-step explanation:
–24 + 12d = 2(d – 3) + 22
–24 + 12d = 2d - 6 + 22
–24 + 12d = 2d + 16
–24 + 12d - 2d = 16
12d - 2d = 16 + 24
10d = 16 + 24
10d = 40
d = 4
