Answer:

so a perpendicular line's slope will be the opposite reciprocal

in 4r-10y=40 the slope of this line is 4/10(-a/b). So the slope of the perpendicular line would be -10/4 (-5/2) hope this helps!

Solve the inequality if possible 4(3-2x)>2(6-4x)

GenaCL600 [577]

Final Answer: No Solution

Steps/Reasons/Explanation:

Question: $4(3- 2x) > 2(6- 4x)$

Step 1: Divide both sides by $2$ .

$2(3 - 2x) > 6 - 4x$

Step 2: Expand.

$6 - 4x > 6 - 4x$

Step 3: Since $6 - 4x > 6 - 4x$ is false, we have no solution.

No Solution

Yolanda has finished 45 percent of her homework and she has finished 27 problems. How many problems was Yolanda assigned

masya89 [10]

If 45 percent of the homework is only 27 problems, she needs to figure out this:

What is 47 percent of 60?
or
47% x 60

Which is 27.

So, Yolanda was assigned 60 problems.

Select the two values of x that are roots of this equation.

makkiz [27]

Answer:

$\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}$

Step-by-step explanation:

Given :-

A quadratic equation is given to us.
The equation is 2x² + 7x +6=0

And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,

Given equation :-

$\implies 2x^2 + 7x +6=0$

Step 1: Find out the factors of 12 :-

We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .

And 3 + 4 = 7. So we will break the middle term into 3x and 4x .

Step 2 : Breaking the middle term :-

$\implies 2x^2 + 3x+4x +6=0$

Step 3: Take out common from terms :-

$\implies x(2x + 3) +2(2x +3)=0$

$\implies ( x +2)(2x+3)=0$

Step 4 : Equate them with 0 :-

$\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}$

Hence the correct options are C and D .

In the diagram below, lines a and b are parallel and cut by transversal, t. If angle 3 is 120 degrees, find the measure of angle

PolarNik [594]

Hi there!

Since angles 3 and 7 are corresponding angles, they are also congruent. This means that angle 3 is equal to angle 7. Therefore, the correct answer is C, 120 degrees.
