Answer:
y=1.40x+8
Step-by-step explanation:
26=1.40x+8
18=1.40x
12=x
Answer:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
Answer: D
Step-by-step explanation:
Only option that has a not equal inequality sign just like the graph.
Answer: 1298 square feet
------------------------------------------------------
Work Shown:
Area of Rectangle on the Left = length*width = c*d = 24*20 = 480
Area of Rectangle in the center = length*width = c*b = 24*10 = 240
Area of Rectangle on the Right = length*width = c*e = 24*17 = 408
Area of top triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Area of bottom triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Add up the individual areas to get:
480+240+408+85+85 = 1298
The units are in square feet since this is dealing with area.
Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
