Provide in simplest form 12% of 40

1 answer:

7 0

To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8

(x1,y1) is (-4,-2) and (x2,y2) is (2,4)

olga nikolaevna [1]

Answer:

y = x+2

Step-by-step explanation:

(x1,y1) is (-4,-2) and (x2,y2) is (2,4)

Slope intercept form is y = mx+b

m = slope

b = add on

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute numbers

Slope = $\frac{4-(-2)}{2-(-4)}$

Two negatives = one positive

Simplify

$Slope = \frac{4+2}{2+4}=\frac{6}{6}=1$

The slope is 1

We can substitute y, x, and the slope

4 = 2*1 + b

4 = 2+b

b = 2

Slope intercept form is y = mx+b

Answer is y = x+2

Hope this helps :)

Products of equal value totaling $480 are sold to an audience of an unknown amount of people. the entrance fee is $10 per person

Sholpan [36]

Y = $\frac{10x+480}{x}$

This is because the total cost is 10x + 480 and then that needs to be divided by the amount of people.
