Answer:
m=2/5
b=3.8
Step-by-step explanation:
To find slope you need to use slope formula which is (y2-y1)/(x2-x1) so you need two points from the table and plug them into this. I'll use the first two points (-2, 3) and (-1, 5)
(5-3)/(3--2)
2/5
our slope is 2/5(m)
now to find the y int(b)
we have out slope intercept formula which is y=mx+b
plug in our slope
y=2/5x+b
now take a random point from our tabell and apply it to our equation I'll use (-2, 3) again.
3=2/5(-2)+b
3=-4/5+b
3=-0.8+b
add 0.8 to each side
3.8=b
b=3.8
An exponent is the same thing as a power. For example, 5 to the fourth power is the same as 5 with an exponent of 4.

Y = 8/cos60 = 16
x = sqr(16^2 + 8^2) = 8sqr(3) = 13.86 approx
Answer:
107
Step-by-step explanation:
8b^2 - 6c + 9
Let b=4 and c=5
8*(4)^2 -6(5)+9
Exponents first
8* 16 -30 +9
Then multiply
128 -30+9
Then add and subtract
107
