Answer:

Step-by-step explanation:

Distribute 2 through the parentheses

Add the like terms : 6x and 4x
Like terms are those which have the same base.

The negative integers are always but added but posses the negative ( - ) sign.

Answer:
The function is equal to 
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(8,-1)
substitute

<u><em>Find the value of a</em></u>
Remember that we have the y-intercept
The y-intercept is the point (0,-17)
substitute
x=0,y=-17






therefore
The function is equal to

see the attached figure to better understand the problem
Answer:
-1/4
Step-by-step explanation:
For this equation, first divide both sides by 1.2, to get x+4y=15. Then, subtract x from both sides. Now, with 4y=-x+15, divide by 4. You should get y=-1/4x+15/4 (15/4=3 3/4 or 3.75). The formula y=kx=b, where k is slope, means the slope is -1/4.
Answer:
B
Step-by-step explanation:
table B: because when x increases y increases at the same rate and stay the same . the graph has proportional relation when it is a straight line passes through origin
for B :25/20=30/24=40/32=5/4
y=5/4 x
5x + 3 is a linear equation in one variable
