solve by linear combination

add 1st and 2nd equation together to get

3x+2y=9


add 2nd and 3rd equation together to get

3x=23

divide by 3

x=23/3

sub into other one


3x+2y=9

23+2y=9

2y=-14

y=-7

Determine the y-intercept of the following parabola:<br> y = (x - 3)(x + 7)
Fofino [41]

Answer:

The y intercept is -21

Step-by-step explanation:

y = (x - 3)(x + 7)

To find the y intercept, set x =0 and solve for y

y = (0-3) (x+7)

y = -3*7

y = -21

The y intercept is -21

HELP QUICK PLS!!!
Tomtit [17]

Answer:

A

Step-by-step explanation:

The lateral surface area is given by pi*r*l, we can use trigonometry to find l. 8*sqrt(3)/l=sin(60), l=16 and r is given by tan(60)=8*sqrt(3)/r, r=8. The lateral surface area is 16*8*pi=128*pi

Solve the system of equations by the substitution method.
xeze [42]
We can substitute the second into the first, this gives:

x -5x = -24 =>
-4x = -24
x = 6

fill in this x value in the second equation:

y = -5*6 = -30

So the solution is x=6, y=-30

Find the distance between the points (4, 0) and (–3, 4).
Vaselesa [24]

Answer:

\huge\boxed{\sqrt{65}\approx8.062}

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have two points (4, 0) and (-3, 4).

Substitute:

d=\sqrt{(-3-4)^2+(4-0)^2}=\sqrt{(-7)^2+4^2}=\sqrt{49+16}=\sqrt{65}
