Answer:
Step-by-step explanation:
Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.
If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.
H(-2) = 2(-2)^2 - 3(-2)
= 2(4) - (-6)
= 8 + 6
= 14
Take 2 points
(3, 9) and (0, 3)
Slope = (Y2 -Y1) ÷ (X2 -X1)
<span>Slope = (3-9) / (0-3)
</span><span>Slope = -6 / -3
</span><span>Slope = 2
The equation will have the form </span><span>y = mx + b</span>
We can rearrange this to b = y -mx
Let's take one of the points (3, 9) and the slope (m) and enter it into the formula:
b = -9 -2*3
b= -3
Now we enter all that data into b = y -mx
and get
y = 2x -3
Answer:
y = 2x+6
Step-by-step explanation:
y-4=2(x+1)
Distribute
y-4 =2x +2
Add 2 to each side
y-4+4 = 2x+2+4
y = 2x+6
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
Answer:
B) 11√3 - 7√6
Step-by-step explanation:
√48 can be simplified to <em>4√3</em>, and √54 can be simplified to <em>3√6</em>.
The equation is now <em>7√3 - 4√6 + 4√3 - 3√6</em>.
This can be grouped into <em>(7√3 + 4√3) + (-4√6 -3√6)</em>.
We get 11√3 - 7√6.
