Mathematics
1 answer:
ololo11 [35]3 years ago
5 0

Answer:

Step-by-step explanation:

1. x^2-x-20=3x-15

x=5, x=1 substitute

y=3*5-15 = 0

y=3*(-1)-15 = -18

Solution: (5,0) & (-1,-18)

2. x^2+2x+3=x+5

x=-2, x=1 substitute

y= -2+5 = 3

y=1+5 = 6

Solution: (-2,3) & (1,6)

Solve the equation 4[c-3]=8<br> what are two ways to solving this equation
Alex17521 [72]

Answer:

Divide both sides by 4 to get c - 3 = 2 ( second to last choice)

Use the distributive property to get 4c - 12 = 8 (last choice)

Step-by-step explanation:

1. Use distributive property

4 times c = 4c

4 times 3 = 12

2. Since we are multiplying by 4, we can divide by 4 on both sides.

4(c - 3) divided by 4 = c - 3

8 divided by 4 = 2

I hope this helped and please mark me as brainliest!

Help me if you understand thanks sm

First, find the slope of the line using the formula for slope:

m = (y2 - y1) / (x2 - x1)

m = (4 - (-2)) / (-3 - 2) = -6/5

Then, use the point-slope formula using a point that you were given and the slope that you calculated.

y - y1 = m(x - x1)

y - 4 = (-6/5)(x + 3)

Then, simply get y alone.

y = (-6/5)x + 2/5
