Answer:
The number is 10
Step-by-step explanation:
Let x be the number
product is multiply
12 + (2x) = 4x -8
Subtract 2x from each side
12+2x-2x = 4x-2x-8
12 = 2x-8
Add 8 to each side
12+8 = 2x-8+8
20 = 2x
Divide by 2
20/2 = 2x/2
10 =x
Answer: To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations.
Step-by-step explanation: hope this helps
Answer:
The other coordinate is (-6,19)
Step-by-step explanation:
(4,-7)
(x,y)
[(4+x)/2 , (-7+y)/2] = (-1,6)
(4 + x)/2 = -1
4 + x = -2
× = -6
(-7 + y)/2 = 6
-7 + y = 12
y = 19
(Correct me if i am wrong)
The answer is x = 6

Answer:
Step-by-step explanation:
slope of required line=5
point is (-1,0)
reqd. eq. of line is
y-0=5(x-(-1))
y=5(x+1)
y=5x+5
