X = 3



-4 - 5x + 10x + 9 = 20

-4 + 5x + 9 = 20

5x + 5 = 20

5x + 5 - 5 = 20 - 5

5x = 15

5x/5 = 15/5

x=3

There is no solution to the following system of equations.
sergij07 [2.7K]

Answer:

True

Step-by-step explanation:

We are given that system of equation

x<3

y>3

We have to find that there is no solution of system of equation is true or not.

First we change inequality equation into equality equation

x=3

y=3

When x=0

0<3

It is true equation therefore, the shaded region towards the origin.

When y=0

0>3

It is false equation. Therefore, the shaded region above the origin.

From the graph

There is  no solution of system of equation.

Hence, option true is correct.

Write the equation of the line that passes through A(-3,-2) and B(1,6).
topjm [15]

Answer:

<h2>y = 2x+4</h2>

Step-by-step explanation:

A(-3,-2) and B(1,6).\\\\x_1 = -3\\y_1 = -2\\x_2 = 1\\y_2 =6\\\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1} \\\frac{y -(-2)}{x -(-3)} =\frac{6-(-2)}{1-(-3)}\\\frac{y+2}{x+3} = \frac{6+2}{1+3} \\\frac{y+2}{x+3} = \frac{8}{4} \\Cross-multiply\\4(y+2) =8(x+3)\\4y +8 =8x+24\\4y = 8x +24-8\\4y = 8x+16 \\OR\\ y = 2x+4

Find the output for the graph<br> y = -6x + 25<br> when the input value is 3.<br> =<br> y = [?]
avanturin [10]

<u><em>Answer</em></u>

x=\frac{11}{3}

<u><em>Explanation</em></u>

Based on the given conditions, formulate:: y=3

Substitute y=3 into y=-6x+25 :: 3=-6x+25

Rearrange variables to the left side of the equation: 6x=25-3

Calculate the sum or difference: 6x=22

Divide both sides of the equation by the coefficient of variable: x=\frac{22}{6}

Cross out the common factor: x=\frac{11}{3}

LaDonna is running for city council. She needs to get four fifths 4 5 of her votes from senior citizens and 40 comma 00040,000 v
Colt1911 [192]
She needs in total 40,000 votes, and from those 40,000, 4/5 need to be from senior citizens, now, 5/5 is a "whole", so 5/5 - 4/5 that leaves only 1/5.

therefore, of those 40,000 votes, 1/5 can be of non-senior citizens, how much is 1/5 of 40,000?  well, is just their product,

\bf \cfrac{1}{5}\cdot 40000\implies \cfrac{40000}{5}\implies 8000
