Find the x- and y-intercept of the line. -4x +2y = 24

1 answer:

4 0

When y = 0, x will equal the x-intercept. So, plug in 0 for the y-value to find the x-intercept.

-4x + 2y = 24 Plug in 0 for y
-4x +2(0) = 24 Multiply
-4x = 24 Divide both sides by -4
x = -6

The x-intercept is (-6, 0).

When x = 0, y will be the y-intercept. So, plug in 0 for x and solve for y.

-4x + 2y = 24 Plug in 0 for x
-4(0) + 2y = 24 Multiply
2y = 24 Divide both sides by 2
y = 12

The y-intercept is (0, 12).

The product in scientific notation is 8*10^2

<h3>How to multiply and divide in scientific notation?</h3>

Here we want to find the product between 4*10^6 and 2*10^6, and write that in scientific notation.

First, we can solve the direct product:

(4*10^6)*(2*10^6) = (4*2)*(10^6*10^6)

Here we used the fact that we can multiply in any order we want.

Now we will use the property:

a^n*a^n = a^{n + m}

(4*2)*(10^6*10^6) = 8*10^{6 + 6} = 8*10^12
