Answer:

-9a + b

Step-by-step explanation:

For this problem, let us factor out the variable a from the terms containing the variable, and apply addition and the distributive property to simplify the terms.

-5a - 4a + b

= a ( -5 + -4 ) + b

= a ( -9 ) + b

= -9a + b

Hence, the simplified expression for -5a - 4a + b is -9a + b.

Cheers.

Answer:

m = -6/7

b = -2

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7

y = mx + b

m = -6/7

y = -6/7 x + b

Use point (-7, 4).

4 = (-6/7)(-7) + b

4 = 6 + b

b = -2

y = -6/7 x - 2

m = -6/7

b = -2

How do you factor and solve x^2-6x=-5
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

You need to bring the -5 to the left side.

x^2-6x+5=0

Wat two numbers, when multiplied equal to +5? Also when added make the middle term or -6?  -5 and -1.

(x-1)(x-5)  The x^2 would factor to be x*x

So the answer is the (x-1)(x-5)

11111nata11111 [884]

Answer:

139

Step-by-step explanation:

First we need to find diameter 132/3.14=42 rounded

Then we halve it to find radius 42/2=21

Formula for area is radius x radius x 3.14

21 x 21 = 441 x 3.14 = 138.74 round up is 139
