Find the x-coordinate of the vertex of a parabola if the x-intercepts are (3,0) and<br> (-9,0)

madam [21]

Answer:

x = -3

Step-by-step explanation:

The vertex lies on the axis of symmetry, whose x-coordinate is halfway between -9 and 3: x = -3

Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions

vaieri [72.5K]

Answer:

Infinite Solutions

Step-by-step explanation:

3(5x - 4) needs to be simplified

So we multiply 5x by 3

So 3 x 5x = 15x

Then we multiply -4 by 3

3 x -4 = - 12

Put those together we get 15x - 12

The same equation as the one on the right side

So since 15x - 12 = 15x - 12, the x variable can be any number

Find the equation perpendicular to the line y=−3x+5 that passes through point (2, 6).

Harlamova29_29 [7]

For a line to be perpendicular, the product of its slope and the given slope must be equal to -1
so..
$\frac{ - 1}{ - 3} = \frac{1}{3}$

now we need to find our y-intercept
we use the given coordinate and our new slope find this
$y - intercept = 5 \frac{1}{3} = \frac{16}{3}$

now to put these together into our final equation
$y = \frac{1}{3} x + \frac{16}{3}$
