Answer:

there are only three simple steps (:

Step-by-step explanation:

1. identify the two points on the line

2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)

3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)

in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)

Solve the system equations <br> y=x^2-8 4x+y=-8

monitta

Insert y in the second equation and solve for x:

4x+(x^2-8)=-8
4x+x^2-8=-8
4x+x^2=0
x^2+4x=0

x = -4

Now you insers this x-value in the first or second equation (i use the first):
y=(-4)^2-8=16-8=8

Therefore the conclusion must be x=-4 and y=8

The nutrition fact on a particular snack food states that 40% of calories come from fat. If 20 of the total calories come from f

OleMash [197]

Answer:

The total calories in the food is 50.

Step-by-step explanation:

Given,

Calories coming from fat = 20

In percentile calories coming from fat = 40%

Solution,

Let the total calories in the food be 'x'.

And given that 40% of the total calories are coming from fat, which is 20.

That means x multiplied with 40% is equal to 20.

So framing the above sentence in equation form, we get;

$x\times40\%=20$

Now we have to remove the percentile.

For this we have to divide 40 by 100, then we get;

$x\times\frac{40}{100}=20\\$

Multiplying by 100 on both side, we get;

$x\times40=20\times100\\\\x=\frac{20\times100}{40}\\\\x=50$

Hence The total calories in the food is 50.
