Answer:

The equation y = 3x - 5 has 2 variables: x and y.

The equation y = 3x - 5 has infinite solutions.

Step-by-step explanation:

Using the image as a reference you could see how the equation y = 3x - 5 is put on a graph. To graph this you want to first start with knowing y=mx+b. M stands for you slope, x stands for your x value, b stands for the y-intercept, and y stands for the y value. You are given both your slope and y-intercept. First put down your y-intercept which is -5 at point (0,-5) (use the image as reference.) You are then given a slope of 3. To graph the slope on the graph you want to rise 3 and run one since 3/1 equals 3. This would then get you to the point (1,-2) where you could just do a straight line on your graph from the two points to get the rest of the line graphed.

The equation y= 1/2 x +4 is graphed below.which equation would intersect this line at (4, 6)?
Anton [14]

Answer:

we have the equation y = (1/2)*x + 4.

now, any equation that passes through the point (4, 6) will intersect this line, so if we have an equation f(x), we must see if:

f(4) = 6.

if f(4) = 6, then f(x) intersects the equation y = (1/2)*x + 4 in the point (4, 6).

If we want to construct f(x), an easy example can be:

f(x) = y = k*x.

such that:

6 = k*4

k = 6/4 = 3/2.

then the function

f(x) = y= (3/2)*x intersects the equation  y = (1/2)*x + 4 in the point (4, 6)

How do you solve this?
geniusboy [140]

Hello from MrBillDoesMath!

Answer:

x = 50


Discussion:

(4x +5) ( 2x - 2) =  8x^2 - 8x + 10x - 10        

                          = 8x^2 + 2x - 10                             (A)


(16x^8)/(2x^6)  + 90 =   8x^2 + 90                           (B)


Setting (A) = (B) gives

8x^2 + 2x - 10 = 8x^2 + 90

Subtract 8x^2 from both sides:

2x - 10 = 90

Add 10 to both sides:

2x = 90 + 10 = 100

Divide both sides by 2:

x = 100/2 = 50




Thank you,

PLEASEEE HELP ME WITH THISSS
zaharov [31]

Answer:

x=14

Step-by-step explanation:

This is asking for the ratio of A to B.

The x-10 is 1.

The 28 is 7.

Find the scale factor by executing 28/7=4.

So, you would want polygon A to be 4 in order to be proportional to polygon B.

Now, you can just guess and check that 14-10=4

Or, you can set up the equation as follows: x-10    =    4

                                                                         +10        +10

                                                                           x      =   14 is your answer.
