Serggg [28]

y = (x - 2)(x + 5)    First I would multiply (x - 2) and (x + 5) together

y = x² + 5x - 2x - 10

y = x² + 3x - 10


Next I would plug in a number for x to find its y value. I will plug in 0

y = 0² + 3(0) - 10

y = -10

(0, -10)   [this is the y-intercept (the y value when x = 0)]


Your answer is Graph A because the y-intercept is (0,-10)

What is the equation in the slope intercept form of the line that passes through the point (2,-2) and is perpendicular to the li
Igoryamba

Answer:

D

Step-by-step explanation:

The slope is 2/5 and the slope of the new line will be -5/2 because the negative reciprocal creates a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

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

y+2=-5/2x+10/2

y=-5/2x+5-2

y= -5/2x+3

What is equivalent to 9 3/4?
Nata [24]

Step-by-step explanation:

We need to say that 9^{3/4} is equivalent to what.

We know that, (3)² = 9

So,

9^{3/4}=((3)^2)^{3/4}\\\\=3^{3/2}

We can write 3^{3/2} =3\times 3^{1/2}

And 3^{1/2}=\sqrt{3}

So,

3\times 3^{1/2}=3\sqrt{3}

So, 9^{3/4} is equivalent to 3\sqrt{3}.

Hence, this is the required solution.
