Answer:

slope = 6

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2.5, - 24) and (x₂, y₂ ) = (4.75, 19.5)

m = \frac{19.5+24}{4.75+2.5} = \frac{43.5}{7.25} = 6

iVinArrow [24]

Answer:

<u>The correct answer is A. 10 - 2</u>

Step-by-step explanation:

1. Let's make all the comparisons for the four alternatives:

A.  3 + 7 > 10 - 2 ⇒ 10 > 8, the comparison is correct because 10 is bigger than 8.

B.  3 + 7 > 9 + 4 ⇒ 10 > 13, the comparison is not correct because 10 is less than 13.

C.  3 + 7 > 7 + 3 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.

D.  3 + 7 > 8 + 2 ⇒ 10 > 10, the comparison is not correct because 10 is equal to 10.

<u>The only correct comparison is A. 10 - 2.</u>

If f(x)= 5x+4 and g(x)= -2+1...... 1) f(6) + g(-8) = ? 2) g(4)= ? 3) f(-2)= ? PLZ PLZ PLZ HELP ME I AM SOOOOO CONFUSED!!!!!!!!!!
MakcuM [25]

Answer:

See below.

Step-by-step explanation:

So we have the two functions:

f(x)=5x+4\text{ and } g(x)=-2x+1

1)

First, find the values of each function:

f(x)=5x+4\\f(6)=5(6)+4\\f(6)=30+4=34

g(x)=-2x+1\\g(-8)=-2(-8)+1\\g(-8)=16+1=17

Therefore:

f(6)+g(-8)\\=(34)+(17)=51

2)

Plug in the number into the function:

g(x)=-2x+1\\g(4)=-2(4)+1=-8+1=-7

3)

Like the last one:

f(x)=5x+4\\f(-2)=5(-2)+4=-10+4=-6
