Which equation is the inverse of y = 7x2 – 10?
MrRissso [65]

we have

y=7x^{2}-10

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

x=7y^{2}-10

Step 2

Isolate the variable y

x=7y^{2}-10

7y^{2}=x+10

y^{2}= \frac{x+10}{7}

Square Root both sides

y=(+/-)\sqrt{\frac{x+10}{7}}

Step 3

Let

f(x)^{-1}=y

so

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}

therefore

<u>the answer is</u>

The inverse is  

f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}

Hey loves!!! Can any of you lovely people give me a hand?
posledela

Hey There!!

Your best answer will be A.

Step-by-step explanation:

Because, The SAS stands for Side Angle Side if you need two sides and then the angle needs to be between them.

The first one works because the angle is in-between the 2 sides. The second one really doesn't work very well. Because, It actually have 2 angles and it only need one. Well, The third one it doesn't work because the angle isn't between from both sides. The fourth one doesn't work at all they are only sides and no angles. Hope This helps <3!!

How are the measures of angles, arcs and segments formed by secant lines that intersect within a circle related?
Drupady [299]

Answer:

The answers below ._.

Step-by-step explanation:

A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.
