Answer: 15=10+5
Step-by-step explanation:
Subtract 55 from both sides.
15-5=a
Simplify 15-5 to 10.
10=a
Switch sides.
a=10

if you have 6 pounds and you use 0.75 pounds per then you can make 6/0.75 dinners = 8
Answer:
Hence, the following equations, when graphed, intersect at the point (4, 0):
x - y = 4 (1)
x + y = 4 (4)
Step-by-step explanation:
<em>" For the graph to intersect at the point (4,0) we mean that when y=0 , x must be equal to 4 or we could say that when x=4 then y=0".</em>
1)
x-y=4
now when y=0 then x=4.
Hence, the graph intersect at the point (4,0).
2)
-x-y=4
When y=0 in the equation then x=-4, Hence the point (4,0) does not lie on the graph of the given function.
3)
2x-y=7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
4)
x+y=4
When y=0 then x=4.
Hence the graph of the given function intersect at (4,0).
5)
2x + y = 7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
6)
2x + y = -7
When y=0 then x= -7/2.
Hence the graph of the function does not intersect at the point (4,0).
Answer:
Slope: 3.
Equation: y = 3x + 8.
Step-by-step explanation:
Lines that are parallel to each other will have the same slopes.
So, the slope of the new line will be 3.
Since we have the slope, and a set of coordinates the line passes through, we can find the equation. So far, we have y = 3x + b. x = -2, y = 2.
2 = 3(-2) + b
3(-2) + b = 2
-6 + b = 2
b = 8
So, the equation of the line will be y = 3x + 8.
Hope this helps!
