-a^2+7b^4-2c^3
-(-4)^2+7(-2)^4-2(-3)^3
= -(16)+7(16)-2(27)
= -16+112-54
=-70+112
=42
Is Jason’s baseball card going up by 2% every year for example
Jason’s baseball card after 1 year is
25×(1.02)^(1)=25.5
It increased by 0.5 in amount after one year
We can actually make two equations here, slope-intercept form and point slope form. Firstly, we need to find the slope. We do that by finding the difference of the y coordinates, and then dividing that by the difference of the x coordinates. 3-(-4)/1-0 is 7. Our slope is 7, slope is m.
Point slope form is y - y1 = m(x - x1). We only need to worry about y1 and x1. Let’s plug our x and y values in. y - (-4) = 7(x - 0). Next, we should simplify this. y + 4 = 7x. Next, we need to isolate y. We do this by subtracting four from both sides. y = 7x - 4
Our point slope form equation is y - (-4) = 7(x-0), and our slope-intercept form is y = 7x - 4. Keep in mind that 7 is our slope, or m, and -4 is our y-intercept.
Answer:

Step by step explanation:
So I done 6x5 as if it was 600x5, then I would do 60x8
600x5=3000
60x8=480
3000+
480=
