y = 2x + 3 - it's a linear function. We only need two points to plot the graph. Select two any x values and calculate the y values:
for x = 0 → y = 2(0) + 3 = 0 + 3 = 3 → (0, 3)
for x = -2 → y = 2(-2) + 3 = -4 + 3 = -1 → (-2, -1)
y > 2x + 3
Dot line an shading above the line (look at the picture).
Answer:
B.6
Step-by-step explanation:
When we add and subtract, we do it from left to right
13+ (-12) - (-5)
13+-12
13-12 = 1
1 - -5
A negative negative is a positive
1 +5
6
Answer:
B. 20
Step-by-step explanation:
64 ÷ 8 + 6(2)
64 ÷ 8 + 12
8 + 12

I’m not sure if this is right but this looks a bit like chemistry so maybe try to get from minutes to seconds as it becomes an ‘S’ which I’m assuming is seconds? so basically try to do dimensional analysis with it and see if that works. Don’t forget to square it though, that’ll throw you off.
( − 5 ) ( + 5 ) ( 2 + 2 5 )
