The formula for a quadratic function is y=ax^2+bx+c.
The vertex is h, k. This can be found by evaluating y to get k, and dividung -b by a in order to get h.

Hope this helps!

∠5 and ∠6 are complementary angles. m∠5=13°

Hatshy [7]

Since they are complementary angles, then the sum of the measure of both angles is 90
So, M/_5 + m/_6 = 90
13+ X = 90
x=77
measure of angle 6 is 77

A line has a slope of -3/4 and has a y intercept of 3. What is the x intercept of the line

natima [27]

Answer:

The x-intercept is 4

Step-by-step explanation:

We are given;

The slope of a line as -3/4

y-intercept is 3

We are supposed to determine the x-intercept;

We need to know that;

The slope of a line is given by the ratio of the change in y to the change in x

The coordinates of y-intercept are (0, 3)

Taking the x-intercept as a, then the coordinates of x-intercept is (a, 0)

But;

slope = Δ in y ÷ Δ in x

Therefore;

$\frac{0-3}{a-0}= \frac{-3}{4}$

Solving for a

$-3a = -12 \\ a =4$

Therefore, the x-intercept is 4
