We need to get our equation to this form:
y = mx + b
that is the line equation with m slope and b y-axis intercept. So lets modify our equation:
<span>4x - 5y = 40
5y = 4x - 40
y = (4/5)x - 8
therefore the y-intercept is -8</span>

If x-y=5 then how does y=-2x-4
mixer [17]
Based on my knowledge, you’d set both equations equal to y, and then set both sides equal to each other then solve.

y=-5+x
y=-2x-4
-5+x=-2x-4
then solve from there

(this could be completely wrong, so don’t only go by my opinion)

How do I solve this?
Snowcat [4.5K]

Answer:

Step-by-step explanation:

First, let's find the area of the triangle. The Area of a triangle can be modeled as

b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24

To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16

16pi= approximately 50.24

50.24/2= 25.12

25.12 + 16 = 41.12

The area of the figure is approximately 41.12 ft^2

Hope this helps and please mark me brainliest, it really helps!
