How many solutions 4(x-5)=3x+7

1 answer:

5 0

$4(x-5)=3x+7 \\ \\ 4x - 20 = 3x + 7 \\ \\ 4x = 3x + 7 + 20 \\ \\ 4x = 3x + 27 \\ \\ 4x - 3x = 27 \\ \\ x = 27 \\ \\$

The final result is: x = 27

Vanessa draws one side of equilateral ΔABC on the coordinate plane at points A(–2, 1) and B(4,1). What are the possible coordina

sukhopar [10]

Answer:

Possible C:

(1 , 1 + 3sqrt(3))

(1 , 1 - 3sqrt(3))

Step-by-step explanation:

AB = 6 units

Midpoint of AB is (1,1)

C would be at x = 1

So, (1,y)

(y-1)² + (1+2)² = 6²

(y-1)² = 36 - 9

(y-1)² = 27

y - 1 = 3sqrt(3)

y - 1 = -3sqrt(3)

y = 1 + 3sqrt(3)

y = 1 - 3sqrt(3)

84 2/3% to a fraction in lowest terms

RoseWind [281]

The evaluation of 84 2/3% to a fraction in its lowest term is $\mathbf{ \dfrac{127}{150} }$

<h3>What is a fraction?</h3>

Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.

From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.

$\mathbf{= 84 \dfrac{2}{3}\%}$

$\mathbf{= \dfrac{(84 \times 3)+2}{3} \%}$

$\mathbf{= \dfrac{254}{3} \%}$

$\mathbf{= \dfrac{254}{3} \times \dfrac{1}{100}}$

$\mathbf{= \dfrac{254}{300} }$

Divide both the numerator and denominator by (2)

$\mathbf{= \dfrac{127}{150} }$

What is the equation of the line that passes through the point (2,-4) and has a slope of -2

kvv77 [185]

Answer:

The answer is

$\huge y = - 2x$

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have

$y + 4 = - 2(x - 2) \\ y + 4 = - 2x + 4 \\ y = - 2x + 4 - 4$

We have the final answer as
