Answer:21x^2-16x-16
Step-by-step explanation:
(3x)(7x)+(3x)(4)+(−4)(7x)+(−4)(4) =
21x^2+12x−28x−16
21x^2−16x−16
Answer:
The equation of the line would be y = 2x - 5
Step-by-step explanation:
To find a line parallel to this one, note that parallel lines have the same slope. Since the first line has a slope of 2, then we know the second does as well.
Now we use that slope and the point in point-slope form and solve for y.
y - y1 = m(x - x1)
y + 7 = 2(x + 1)
y + 7 = 2x + 2
y = 2x - 5
Answer:
x = 0
Step-by-step explanation:
8 + 6x = 4 * 2
If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides
6x = 0
Divide 6 from both sides
x = 0
To test this, insert the value of x which is 0
8 + 6(0) = 4 * 2
Multiply 6 and 0
8 + 0 = 4 * 2
Multiply 4 and 2
8 + 0 = 8
Add
8 = 8
This equation is true as you can see so x is equal to 0.
Hope this helps.
