Please help! Geometry tangents
Ymorist [56]
Since ∠ABC is a right angle, we shall use Pythagoras Theorem to solve for x.

 \boxed {\boxed{a^2 + b^2 = c^2}}

x^2 + 7^2 = ( x + 5)^2

x^2 + 49 = x^2 + 10x + 25

10x = 49 - 25

10x = 24

x = 2.4

Answer: x = 2.4

Pls pls pls help for points
stepladder [879]

Answer:

see below

Step-by-step explanation:

g(x) = (x+2)^2 -1

The function is in the form

g(x) = a(x-h)^2 +k

where (h,k) is the vertex of the parabola

Rewriting

g(x) = (x+2)^2 -1

      = (x--2)^2 + -1

      The vertex is (-2,-1)

We can find another point by letting x =0

g(0) = (0+2)^2 -1

      =2^2 -1

      =4-1 =3

The second point is (0,3)

A line passes through (6,3) (8,4) and (n,-2) what's the value of n
andreev551 [17]
So the equation we are working with is y=mx +b. If you use the distance formula, you will find the slope. The slope is 1/2 and the y intercept is 0. your equation is y=1/2x. So plug in the point that it gives you.

-2 is your y value.

so it will look like this: (x could also be n)

-2=1/2x...solve....n=-4
