The equation: y = 2x/3 + 4 is a line with infinite values for x. So unless you have a y-value to plug in to find the corresponding x-value all you can do is write the equation in terms of y.

x = 3(y-4)/2

The slope and intercepts on the other hand can be determined from the given equation. y= mx + b is slope-intercept form of a linear equation. "m" is the slope and "b" is the y-intercept. Plug in y = 0 to find the x-intercept.

I don’t know the answer to that one can you help me please

dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1: When dividing fractions, use “KFC”. It means Keep the first fraction, Flip the second one, and

Change it to multiplication

-4/20 ÷ -9/16 → -4/20 ∙ 16/-9

Step 2: Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end. It’s easier arithmetic to reduce at this step. The first fraction reduces because both the numerator and denominator are divisible by 4.

-1/5 ∙ 16/-9

Step 3: Multiply numerators and denominators together to get one fraction

(-16)/(-45)

Step 4: Cancel out the negatives, a negative divided by a negative is a positive. Our final answer is

16/45

Find the area of the shaded regions round the hundredth if needed.

inn [45]

1. Find the area of the circle. You know the radius = 10 in. Use
$a = \pi {r }^{2}$
2. Find the area of the (I'm assuming) equilateral triangle. Use the 30-60-90 rule to determine the length of half one of the edges, since you already know the hypotenuse of the 30-60-90 triangle. Multiply that value by 2 to get the length of one side. Then use
$a = \frac{ \sqrt{3} }{4} {l}^{2}$
to find the area, where l = length of one side.

3. Subtract the area of the equilateral triangle from the area of the circle to find the area of the shaded region.

Hope this helps. Let me know if you're confused!
