sergiy2304 [10]

Answer:

 13m²−35m+8−4m³

Step-by-step explanation:

Expand (1 − 4m)(m² − 3m + 8) by multiplying each term in the first expression by each term in the second expression.

1m² + 1 (−3m) + 1 ⋅ 8 − 4m ⋅ m² − 4m (−3m) − 4m ⋅ 8

Find the equation of the line shown
yuradex [85]

Answer:

y = 2x - 1

Step-by-step explanation:

The line shown is a straight line its equation is of the form.

y = mx + c

Where m is the slope and c is the y-intercept.

From the graph, the slope is

m =  \frac{rise}{run}

m =  \frac{2}{1}  = 2

The y-intercept from the graph is where the line intersects the y-axis, so c=-1

We substitute the values to get:

y = 2x - 1
