Answer:

you require two numbers m and n such that. x² + bx + c = (x - m)(x - n) where. m + n = b. and. mn = c. In the case where c = 22 and m & n are integers, we have. mn = 22. But, the (positive) …

Crank

we know that

the equation of the line in the point-slope form is equal to

y-y1=m(x-x1)

we have

y+6=45(x+3)  

so

the point is (-3,-6)

the slope is m=45

<u>With the slope and the point, find the second point</u>

m=45=\frac{4.5}{0.10}

the x-coordinate of the second point will be

-3+0.10=-2.90

the y-coordinate of the second point will be

-6+4.5=-1.5

the second point is (-2.90,-1.5)

How many solutions does the system have?
slavikrds [6]

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = 3x + 3 → (1)

y = - 2x + 3 → (2)

Substitute y = 3x + 3 into (2)

3x + 3 = - 2x + 3 ( add 2x to both sides )

5x + 3 = 3 ( subtract 3 from both sides )

5x = 0 , then

x = 0

Substitute x = 0 into (1)

y = 3(0) + 3 = 0 + 3 = 3

solution is (0, 3 ) → A
