3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.

4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2

5. When you look at the graph, when x=7, then y=80. So the student may get an 80.

How do you Subtract 9x^2 + 22x - 46 from 12x^2 - 8x + 12.
Luba_88 [7]

Subtract the x^2 terms from each other, then the x terms, then the ones without any x whatsoever.

(12x^2 - 8x + 12) - (9x^2 +22x-46)

First, we'll subtract 9x^2 from 12x^2

12x^2-9x^2- = 3x^2

Result: 3x^2

Next, we'll subtract 22x from -8x

-8x - 22x = -30x

Result: -30x

Finally, we'll subtract -46 from 12

12-(-46) = 12+46 = 58

Result: 58

Now, we can add these 3 results together.

First, we had 3x^2, then -30x, and finally 58.

Thus, our subtraction of

(12x^2 - 8x + 12) - (9x^2 +22x-46)

equals

3x^2-30x+58

1/2 + 1/3 - 1/4 = I don't know
larisa [96]
Use "PEMDAS"
First we'll add then subtract

\frac{1}{2} + \frac{1}{3} =  \frac{2}{6} +  \frac{2}{6} =  \frac{4}{6}= \frac{2}{3}

\frac{2}{3} -  \frac{1}{4} =  \frac{8}{12} -  \frac{3}{12} =  \frac{5}{12}

\frac{1}{2} +  \frac{1}{3} -  \frac{1}{4} =  \frac{5}{12}
