**Answer:**

using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

**Step-by-step explanation:**

Given the expression

- 7a+49b - 35

Rewrite -35 as 5 · 7

Rewrite 49 as 7 · 7

so

= -7a + 7 · 7b - 5 · 7

as -7 is the common factor, so factoring out

= -7(a-7b+5)

Thus, using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Question

Pls help!(: 1. find f(0) and use the function f(x)=2|x+10|-6
2. find x if g(x)=20 use the function g(x)=x+1
3. find g(0)+f(1) using the functions f(x)=2|x+10|-6 and g(x)=x+1
Please explain Im confused..

Solution 1

** Question 1)**

Given the function

f(x) = 2|x+10| - 6

You need to remember that:

f(x) = y

f(0) means we need to determine the value of y at x = 0.

so substitute x = 0 in the function

Apply absolute value:

Thus,

** Question 2)**

Given the fuction

g(x) = x+1

substitute g(x) = 20 in the function

20 = x+1

x = 20-1

x = 19

Thus,

x = 0

** Question 3)**

Given the function

f(x)=2|x+10|-6

substitute x = 1 in the function

f(1)=2|1+10|-6

f(1)=2|1+10|-6

f(1) = 2|11| - 6

Apply absolute value:

f(1) = 2(11) - 6

f(1) = 22 - 6

f(1) = 16

Given the function

g(x)=x+1

substitute x = 0 in the function

g(0) = 0+1

g(0) = 1

Thus,

g(0)+f(1) = 16+1

= 17

Question

The area of a rectangular wall of a barn is 33 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn, The width is feet.?

Solution 1

**Answer:**

**Width = 3ft **

**Length = 11ft**

**Step-by-step explanation:**

Given parameters:

Area of rectangular wall = 33ft²

Unknown:

Length and width of the wall of the barn = ?

Solution:

So;

Area of a rectangle = length x width

Let the length = L

width = W

L = 8 + W

33 = (8 + W)W

33 = 8W + W²

W² + 8W - 33 = 0

W² + 11W - 3W - 33 = 0

W(W + 11) - 3(W + 11) = 0

(W - 3)(W + 11) = 0

W - 3 = 0 or W + 11 = 0

So; W = 3

To find the length;

L = W + 8

L = 3 + 8 = 11

Question

Keith and Sarah Robinson purchased 40 stamps, a mixture of 49 cent and 34 cent stamps. Find the number of each type of stamp if they spent $17.35.

Solution 1

There are 2 equation. First let 49 cent stamps be f and 34 stamps be t.

One equation would be f+t=40 the other one would be .49f+.34t=17.35. You can do substitution if you want or elimination.

Put the two in line

49f+34t=1735

f+t=40----> elimination

-34(f+t=40)--> solve

49f+34t=1735

-34f-34t=-1360 --->solve

---------------------

15f =375--> divide

f=25

Then put this on the first equation to find the other answer.

One equation would be f+t=40 the other one would be .49f+.34t=17.35. You can do substitution if you want or elimination.

Put the two in line

49f+34t=1735

f+t=40----> elimination

-34f-34t=-1360 --->solve

---------------------
