Answer:

x= 4 is a solution

Step-by-step explanation:

Answer:

When x = -3 is given, all you need to do is substitute and check if the answers in LHS and RHS are equal.

2x+4=8+x

2(-3)+4=8+(-3)

-6+4=8-3

-2 [tex]\neq[/tex] 5

NO SOLUTION

Answer:

Week 4

You have to make a function table.

Answer:

Answer:

9 weeks

Step-by-step explanation:

5x+75=10x+30

-5x        -5x

75=5x+30

-30      -30

45=5x

÷5    ÷5

9=x

x=9

it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

To determine the number of weeks it takes for both you and your friend to have the same amount of money in your savings accounts, we need to set up an equation.

Let's denote the number of weeks as 'x'. For you, the amount of money in your savings account after 'x' weeks can be calculated as follows:

Amount of money in your account = $75 + $5x

For your friend, the amount of money in his savings account after 'x' weeks can be calculated as:

Amount of money in your friend's account = $30 + $10x

To find the number of weeks where you both have the same amount of money, we set up the equation:

$75 + $5x = $30 + $10x

Simplifying the equation:

$5x - $10x = $30 - $75

-$5x = -$45

Dividing both sides of the equation by -5 gives us:

x = 9

Therefore, it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

Answer:

Step-by-step explanation:

Enter the image of each vertex as an ordered pair.

A -> A = (-7,7)

B -> B = (-1,3)

C -> C = (-4,2)

Graph the​ pre-image and image of  ABC. Choose the correct graph below.

Answer is C

Answer:

Here's a screenshot of the correct line:

The line with the slope of 3/5 and goes through the point (1,2) is y = 3/5x + 7/5

The equation of a straight line is given by:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the line has a slope of 3/5 and goes through the point (1,2). The equation of the line is given by:

[tex]y-y_1=m(x-x_1)\\\\y-2=\frac{3}{5}(x-1)\\\\y-2=\frac{3}{5}x-\frac{3}{5} \\\\y=\frac{3}{5}x+\frac{7}{5}[/tex]

Answer:

B. Domain: {1, 3.5, 5, 7.5, 9}

F. Range: {2, 6.50, 7.00, 9.00, 12.50}

Step-by-step explanation:

The set of input values make up the domain of the function, while the corresponding set of output values is the range of the function.

That is, the domain is the number of hours, while total cost is the total cost.

Domain would be: {1, 3.5, 5, 7.5, 9}

Range would be: {2, 6.50, 7.00, 9.00, 12.50}

Answer:

22.5 glasses of water

Step-by-step explanation:

Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.

Answer: The answer is k= -9

Step-by-step explanation:

this is how you solve it :

-8+k=-17

so then you add 8 to both sides so it would look like

-8+k+8=-17+8

then you simplify

after you simplify it would equal k=-9

THATS ALL :) have a good day

also could you please make me brainleast ???

Answer: 3x-2y=-7=  Slope = 3.000/2.000 = 1.500

 x-intercept = -7/3 = -2.33333

 y-intercept = 7/2 = 3.50000

2x+5y+=8

 Slope = -0.800/2.000 = -0.400

 x-intercept = 8/2 = 4

 y-intercept = 8/5 = 1.60000

Answer:

C. 3

Step-by-step explanation:

Formula for slope is given as [tex] m = {y_2 - y_1}{x_2 - x_1} [/tex]

The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).

Let,

[tex] (1, 5) = (x_1, y_1) [/tex]

[tex] (2, 8) = (x_2, y_2) [/tex]

Plug the values into the formula:

[tex] m = {8 - 5}{2 - 1} [/tex]

[tex] m = {3}{1} [/tex]

[tex] m = 3 [/tex]

Answer:

$1.80, $2.90, $4.00, $10.90

Step-by-step explanation:

For 9/10 mile, the price will be $1.80. For 2 miles, the price will be $2.90. For 3 1/10 miles, the price will be $4.00, and for 10 miles, the price will be $10.90. The relationship between distance travelled and the price is not proportional because it costs $1.00 for the first 1/10 mile and then for every additional 1/10 mile, it only costs $0.10. Hope it helps!
