Vestigating Slope and y-intercept
The graph of every nonvertical line crosses the y-axis. The y-interceptis
the y-coordinate of the point where the graph intersects the y-axis. The
x-coordinate of this point is always 0.
The graph represents the linear equation y=-}x+4.
STEP 1 Find the slope of the line using the points (0,4)
and (-3,6).

STEP 4 Find the value of y when x = 0 using the equation y =
= - 2 x +4.
Describe the point on the graph that corresponds to this solution.
STEP 5
Compare your answer in Step 4 with the equation of the line.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

step-by-step explanation:

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
