So we know the slope has to be -3 and the y intercept is 2. y intercept looks like (0,2). since we know this we automatically can rule out B since it has (0,0).

let’s find the slope of A
-9- -5
-3- - 1
the slope= -4/-2= 2
we know it’s not A because the slope is not -3

let’s find the slope of C
-17- -8
-5- -2
slope= -9/-3=3
we know it’s not C because the slope is not -3. we could directly assume that D is the answer no but we’ll still find the slope just to be sure

let’s find the slope of D
14-8
-4- -2
slope=6/-2= -3

the answer is D!!

Answer:

The width of the frame is 3 inches

Step-by-step explanation:

We are told that the inner rectangle is 10 inches by 16 inches.

It means the outer rectangle has to be (L = 10 + 2x) by (W = 16 + 2x),

Where x represents the width of the frame.

The perimeter of the frame is given by; p = 2L + 2W

p = 2(10+2x) + 2(16+2x)

We are given perimeter, P = 76

Thus;

2(10 + 2x) + 2(16 + 2x) = 76

Divide both sides by 2 to give;

(10+2x) + (16+2x) = 38

(10+16) + (2x+2x) = 38

4x = 38 - 26

4x = 12

x = 12/4 = 3

The width of the frame is x = 3 inches

Find the value of x. To the nearest Tenth.
ASHA 777 [7]
Tan 35 = x/12
⇒ 0.7 = x/12
⇒ x = 12 × 0.7
⇒ x = 8.4 cm

Answer:

ab • (11a + b + 1)  If its not im really sorry

Step-by-step explanation:

STEP one

 (((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)

STEP Two

 ((((3a2 • b) +  5ab) -  4ab) +  ab2) +  23a2b

STEP 3

STEP 4

Pulling out like terms

4.1     Pull out like factors :

  11a2b + ab2 + ab  =   ab • (11a + b + 1)
