B. y= 3x -9
C. y= 3x + 8
D. y = 5x - 8
E. y = 2x - 8
F. y = 1/3x -8

Answers

Answer 1
A D E F all have the same y-int which is -8

Y=mx+b
B is the y intercept
M is the slope
Answer 2

Answer:

A, D, E, F

Step-by-step explanation:

They all have the same y-intercept -8.

The formula is like this y = mx + b

m = slope

Answer:

x = - [tex]\frac{41}{14}[/tex]

Step-by-step explanation:

Given

7(2x + 6) = 1 ← distribute parenthesis on left side

14x + 42 = 1 ( subtract 42 from both sides )

14x = - 41 ( divide both sides by 14 )

x = - [tex]\frac{41}{14}[/tex]

Answer:

GCF is Greatest Common Factor.

Explaination:

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

What is linear pair?

Linear pairs of angles are created when two lines cross at a single point. Angles are said to as linear if they are contiguous to one another following the junction of two lines. If two angles are adjacent and their measurements add up to 180°, they are supplementary. As a result, a pair of linear angles always sums to 180°.

In a linear pair, the total of the two angles is always 180 degrees.Angles that are next to one another are called linear pairs, however not all adjacent angles are linear pairs.A common vertex and common arm are shared by a pair of linear angles.

Given:

<1 = 5x-15

<2 = 90

<3 = 2x

Now, using Linear pair

5x - 15 + 90 + 2x= 180

7x + 75 = 180

7x = 180-75

7x= 105

x= 105/7

x= 15

Hence, the value of x is 15.

Answer:   -26

=================================================

Explanation:

Replace every x with -3

Then use the order of operations (PEMDAS) to simplify

y = -2x^2 + x - 5

y = -2(-3)^2 + (-3) - 5 ... x replaced with -3

y = -2(9) - 3 - 5

y = -18 - 3 - 5

y = -21 - 5

y = -26

Answer:

-26

Step-by-step explanation:

1. plug in -3 for all x's

  -2(-3)^2 + (-3) -5

2. combine like terms

  -2(-3)^2 - 8

3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)

  -2(9) - 8

4. peMdas. multiply -2 and 9 next.

  -18 - 8

5. pemdaS. subtract 8 from -18.

  -18 - 8 = -26

graph a line with a slope of -5 that contains the point (-3, -4)

Answers

Answer:

y = -5x-19

Step-by-step explanation:

Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.

Formula: y-y1 = m(x-x1)

m = slope

x1 = x-value

y1 = y-value

Answer:

y=-5x-15

Step-by-step explanation:

starts off in point-slope form:

y+4=-5(x+3)

distribute the 5:

y+4=-5x-15

subtract 4 from each side:

y=-5x-20
