Answer:

(-5, 38) and

(5,18)

Step-by-step explanation:

x^2-2x+3=-2x+28\\ x^2-2x+3+2x=28\\ x^2 = 28-3=25\\ x^2-25=0\\ x^2-5^2 =0\\ (x-5)(x+5)=0\\ x = 5 \ or \ x=-5

so the solutions are

(-5, 38) and

(5,18)

Please help me I’m stuck on these questions :(
bagirrra123 [75]

Answer:

Step-by-step explanation:

4) Money per hour = Total Money / Total Hours

=> 240 / 8

=> $ 30 Per Hour

5) There is a line formula which is "y = mx + b".

In this, "m" is the slope.

"b" is the y-intercept.

"y" is the y-axis line.

"x" is the x- axis line.

y-intecept means that a point on the graph which has the x value as "0" and y value as anything.

Slope is rise / run.

So, by looking at the graph, we can tell that the y-intecept is (0,0). So, the y-intercept is 0.

Slope = y2 - y1 / x2 - x1

=> 10 - 0 / 2 - 0

=> 10/2

=> 5

So, the equation looks like y = 5x.

6) This is the same question as the above one.

=> Y - intercept = (0,5)

So, the y-intecept is +5.

Now, the equation is  y = mx + 5

=> Slope.

=> Slope of the points (0,5) and (2,8).

We used points (2,8) because the line passes through these points.

=> 8 - 5  /  2 - 0

=> 3 / 2

So, the equation is y = 3/2x + 5

7)  By looking at Rebecca's equation, we can tell that her hourly pay is $9.25.

For Andrew's hourly pay, we need to find the slope of the points.\

Slope = y2 - y1  / x2 - x1

=> 57 - 47.5  /  6 - 5

=> 9.5 / 1

So, the equation for Andrew looks like  y = 9.5x

So, we can tell that Andrew's hourly pay is 9.5.  Rebecca's hourly pay is 9.25

USING OLDER BROS ACC THIS IS HOW MUCH I NEED HELP PLEASE BE QUICK--------------------
lesya692 [45]
Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi 
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.
