Find the solutions to the equation below check all that apply 4x2 -8x +3 =0

notka56 [123]

Answer:

Hello :

4x² - 8x +3 = 0

4 ( x² - 2x +3/4 ) = 0

4 ( (x² -2x +1) -1 + 3/4) = 0

4 ((x-1)² - 1/4 ) =0

(x-1)² - 1/4 = 0

(x-1)² - ( 1/2 )²=0

( x - 1 -1/2 ) ( x - 1 +1/2 ) = 0

( x - 3/2) ( x - 1/2) = 0

x - 3/2 = 0 or x - 1/2 = 0

two solutions : 3/2 ; 1/2

Here you have an equilateral triangle. Because of this you know that all angles are also the same as each other. We know that the angles in an equilateral triangle are 60°.

so let's set 7x + 4 = 60
Subtract 4 from both sides: 7x = 56
Divide both sides by 7: x = 8

yuradex [85]

Answer:

The grade you make on your exam varies directly with the number of correct answers. The constant of variation is 5

Solution:

Given, The grade you make on your exam varies directly with the number of correct answers you get on the exam.

Answering 15 questions correctly will give you a grade of 75 what is the.

We have to find what is the Constant of variation.

Now, according to the given information, grade  number of correct answer

Then, grade = c x number of correct answers, where c is constant of variation.

Now, substitute grade = 75 and number of correct answers = 15

$\text { Then, } 75=c \times 15 \rightarrow c=\frac{75}{15}=5$

Hence, the constant of variation is 5
