1 answer:
Ipatiy [6.2K]4 years ago
5 0

Answer:

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= - 4x² - 6x - 1 + (- x² - 5x + 3) ← remove parenthesis

= - 4x² - 6x - 1 - x² - 5x + 3 ← collect like terms

= - 5x² - 11x + 2 → C

Given the parent graph
zzz [600]

Using translation concepts, it is found that the new function was reflected over the x-axis and vertically compressed by a factor of 3.

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

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The functions are given as follows:

  • Parent: f(x) = 4^x.
  • Translated: f(x) = -\frac{1}{3} \times 4^x.

The translated function was multiplied by -1/3, hence it was reflected over the x-axis(multiplication by negative number) and vertically compressed by a factor of 3(fraction of 1/3).

What is the sum or difference of 5/7 - 1/3
Hatshy [7]
ANSWER: 8/21

Step:
1. Find the GCF (Greatest Common Factor)
           The two denominator which is the bottom number have to be the same ALWAYS when adding and subtracting the fraction. So to find the GCF, you keep multiplying until you see the same number, only use the bottom number to find the GCF
      7: 7, 14, 21, 28
      3: 3, 6, 9, 12, 15, 18, 21, 24, 27
         GCF= 21

2.  5/7 -1/3
    Multiple both to get 21
        5/7 x 3/3 = 15/21
        1/3 x 7/7 = 7/21

3. Sove
     15/21 - 7/21
        = 8/21

A magic carpet is made with three colors of yarn. The ratio of each color in the carpet is shown below: 10 parts gold yarn 7 par
ioda

Answer:

There are 22.5 meters of silver yarn

Step-by-step explanation:

Gold yarn : bronze yarn : silver yarn

10 : 7 : 3

Gold yarn = 10

bronze yarn = 7

silver yarn = 3

Total ratio = 20

Total meters = 150 meters

How much silver yarn is in the magic carpet?

Quantity of silver yarn in the carpet = silver yarn ratio / Total ratio × total meters of yarn

= 3 / 20 × 150

= 450 / 20

= 22.5 meters

There are 22.5 meters of silver yarn

Bronze yarn = bronze yarn ratio / Total ratio × total meters of yarn

= 7 / 20 × 150

= 1,050 / 20

= 52.5 meters

Bronze yarn = 52.5 meters

Quantity of gold yarn in the carpet = gold yarn ratio / Total ratio × total meters of yarn

= 10 / 20 × 150

= 1500 / 20

= 75 meters

Gold yarn = 75 meters
