Answer:

(-3, 18) ; (-1, 6)

Step-by-step explanation:

y = x^2-2x + 3

y = -6x

-6x = x^2 - 2x + 3

x^2 + 4x + 3 = 0

(x+3)(x+1) = 0

x = -3

x = -1

Solution 1

x= -1

y = 6

Solution 2

x= -3

y = 18

What is the area of this figure?

Tomtit [17]

Answer:

85.1 (I think)

Step-by-step explanation:

2×2=4

5×2=10

5×6=30

(3×10)÷2=15

3squared+10squared=√109=10.44

5×10.44=52.2÷2=26.1

26.1+4+10+30+15=85.1

Solve for x. 4+3/5(15+2x)=25

erik [133]

If you would like to solve 4 + 3/5 * (15 + 2x) = 25 for x, you can do this using the following steps:

4 + 3/5 * (15 + 2x) = 25
3/5 * (15 + 2x) = 25 - 4
9 + 6/5 * x = 21
6/5 * x = 21 - 9
6/5 * x = 12 /*5/6
x = 12 * 5/6
x = 10

The correct result would be x = 10.

The bottom of a doorway to a building is 3.45 feet above the ground, and a ramp to the door for the disabled is at an angle of 6

Darya [45]

Answer:

The ramp should be 32.9 feet longer.

Step-by-step explanation:

When the ramp is at $6^{o}$ to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;
