7a: Let f(x) = 4x. The graph of f(x) is transformed into the graph g(x) by a vertical stretch of 2 units and a translation of 5

units right. What is the equation for g(x)?
7b: Let h(x) = 10x. The graph of h(x) is transformed into the graph of g(x) by a vertical compression of 1/2 and a translation of 3 units up. What is the equation for g(x)?

Vertical stretch means y values are multiplied by 2, so 2f(x).
Translation of 5 units to the right, means x values minus 5 (it does the opposite to what you might think)
So overall g(x) = 2f(x-5) = 2(4(x-5)) = 8(x-5) = 8x-40

Vertical compression means y values are halved
3 units up mean y values plus 3
So ½h(x) + 3 = g(x) = ½(10x) + 3 = 5x + 3

An 8 oz box of cocoa puffs costs $1.59 and a 2-pound box costs $6.79. which box is a better buy
VikaD [51]

Answer: 8 oz..

1 pound= 16oz if 8oz=1.59 so add it up 4 times 8+8+8+8= 32 which = 2 pounds total 8=1.59 8+8= 1.59x2=3.18 8+8+8=1.59x3=4.77 8+8+8+8/ 1.59x4= 6.36 so all of them eights will = up to 2 pounds and 8 is obviously less

How to add and subtract fractions
Nat2105 [25]
To add or subtract fractions , their denominator ( The one beneath the numerator, the one that divides the numerator ).

If they both terms have the same denominators you just have to add or subtract their numerators and stay with your denominator:

example: 3/5 + 4/5 = 7/5
2/3 - 1/3 = 1/3

But if the terms you are adding or subtracting do NOT have the same denominator , you have to make their denominator equal by equivalency :

Example : 2/3 + 1/6
I cant add 2/3 to 1/6 because they have different denominators. But if I multiply 2/3 by 2/2 it wil be 4/6:
4/6 + 1/6 = 5/6 !!
As 2/2 = 1 , I did not change the value but I changed the numerator and denominator of 2/3 :
If I multiply the numerator of a fraction by any number , but I do the same thing to the denominator, It creates a equivalency, where I dont change the actual values of the fraction.

I hope you understood my brief explanation , and please consider marking this awnser as Branliest if you think it deserves it. Thank you ! :)

Find the slope of the line below. Enter your answer as a fraction of
Levart [38]

Answer:

  • \boxed{\sf{\dfrac{3}{10}}}

Step-by-step explanation:

Use the slope formula.

<h3 /><h3>What is a slope?</h3>

Slope is a surface with one end higher than the other and with no steps. It proceeds at an angle. The path sloped down to the beach.

So, the property possessed by a line or surface that departs from the horizontal.

<u>Slope formula:</u>

\longrightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

(-6,-2) (4,1)

  • y₂=1
  • y₁=(-2)
  • x₂=4
  • x₁=(-6)

<u>Rewrite the problem down.</u>

\sf{\dfrac{1-\left(-2\right)}{4-\left(-6\right)}}

<u>Solve.</u>

1-(-2)=1+2

<u>Add.</u>

1+2=3

4-(-6)=4+6

4+6=10

\boxed{\sf{\frac{3}{10} }}

Therefore, the slope is 3/10, which is our answer.
