Answer:

3

Step-by-step explanation:

We'd just substitute the value provided to us with the variable.

-7(-1) - 2(2)

-7 * -1 = 7

The answer is the 3rd option, y>2/3x+3



This is because first of all, the slope is 2/3x I figured out it was 2/3 because I picked two points, (0,3) and (-3,1). Then I found slope which was 2/3x. I looked at the graph, and the y-int was 3 so good so far. Then I put y is GREATER because it’s shading above the line!!!

Without solving an equation, determine whether 1/4% of 80 is less than, equal to, or greater than 25% of 80?
Anettt [7]

1/4= 0.25%

25%>0.25

So, 25% of 80 is more than 1/4% of 80 and 1/4% of 80 is less than 25% of 80.

Find the measure of an angle in a regular polygon with 22 sides​
KonstantinChe [14]
Find the sum of the interior angles of a 22-gon. Since the polygon has 22 sides, we can substitute this number for n: (n 2)180˚= (22 2)180˚= 20180˚= 3600˚. Each angle of a regular polygon measures 157.5˚.

SCORPION-xisa [38]

Answer: Thus, the equation of a function stretched vertically by a factor of 2 and then shifted 3 units up is y = 2f (x) + 6, and the equation of a function stretched horizontally by a factor of 2 and then shifted 6 units left is y = f ( (x - 6)) = f ( x - ). Example: f (x) = 2x2.
