Answer: y-1=-4(x+7)
Point-slope Formula: y-y1=m(x-b)
7,6, 8,5. 9,4, 10,3 ,11 ,2. 12,1
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
Step-by-step explanation:
there should 90 value
the value of triangle is 90
The x which achieve these statement is x=0.
