Answer:
160 because dat is so simple
Answer:
The equation is y = x + 9.
Step-by-step explanation:
We need to equation of SR
Slope = slope of UV = 3/2
= 1.
One point on SR is (-2, 7) so using the point-slope form of the equation:
y - y1 = m(x - x1)
Here m = 1, x1 = -2, y1 = 7:
y - 7 = 1(x - (-2))
y - 7 = x + 2
y = x + 9
Answer: 1
Step-by-step explanation:
Gcf of 3 : 1 * 3
Gcf of 12184 : 1 * 12184
2 * 6092
4 * 3046
8 * 1523 .......
Gcf of 1545: 1 * 1545
3 * 515
5 * 309
All the the numbers do not have any common number except 1 so therefore 1 is the only common number which makes It the GCF in all three numbers.
-3x + y = 4
Solve for y
y = 3x + 4
Plug this y value into the other equation.
-9x + 5y = -1
-9x + 5(3x + 4) = -1
Distribute 5(3x + 4)
-9x + 15x + 20 = -1
Subtract 20 from both sides
-9x + 15x + 20 - 20 = -1 - 20
-9x + 15x = -21
Combine like terms
6x = -21
Divide both sides by 6
6/6 x = -21/6
1x = -21/6
x = -7/2
x = -3.5 or -7/2
Plug this value into an equation to solve for y.
-3(-3.5) + y = 4
10.5 + y = 4
Subtract both sides by 10.5
10.5 - 10.5 + y = 4 - 10.5
y = -6.5
Check this answer by plugging the value of x into the other equation.
-9(-3.5) + 5y = -1
31.5 + 5y = -1
Subtract both sides by 31.5
31.5 - 31.5 + 5y = -1 - 31.5
5y = -32.5
Divide both sides by 5
y = -6.5 or -13/2
Therefore the solution is ( -3.5 , -6.5 )
