Answer:
A
Step-by-step explanation:
Answer:
x = 50 in
Step-by-step explanation:
Since it is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
14^2 + 48^2 = x^2
196 + 2304 = x^2
2500 = x^2
Take the square root of each side
sqrt(2500) = sqrt(x^2)
50 =x
x = 50 in
Answer:B & E
Step-by-step explanation:
We can first rearrange the function to isolate y. Then, we can find the slope as the function is in the form y=mx+b.

Since parallel lines have the same slope, we can put the slope of 3/4 into the point slope form to get the answer.
<em>For reference, the point-slope form is </em>

The first line is found in option E, so option E is one of the correct options.
We can also move the x to the other side, as two of the 5 options have both variables on the left (B and C).

If we multiply the whole equation by -4, we can get rid of the fraction.

Hence, option B is also correct.
ANSWER
C. 58°
EXPLANATION
The sum of the interior angles of a triangle is 180°.
We sum all the three angles to obtain,
.
We group like terms to get,
.
Simplify,
.
Combine like terms to get,
.
Simplify,
.
Divide both sides by 32 to get,
.
We substitute the value of x into the expression for
.
This implies that,
.
.
.
The correct answer is C
Let

, where

and let

be any real constant.
Given this definition of scalar multiplication, we can see right away that there is no identity element

such that

because
