Answer:
Q = 4
Step-by-step explanation:
Q = 13 - 9
Step-by-step explanation:
3x²+4=31
3x²=31-4
3x²=27
x²=27÷3
x²=9
x=±3
Bc and ef are congruent so that means
4x-7 =2x+3 subtract 2x from both sides
-2x -2x
_________
2x-7 = 3 add seven to both sides
+7 +7
________
2x = 10 divide both sides by 2
__ ___
2 2
x=5 replace x with 5
4(5) -7= 13
2(5) +3=13
both bc and ef equal 13
Answer:
x=3, y=22. (3, 22).
Step-by-step explanation:
-5x+3y=51
y=10x-8
----------------
-5x+3(10x-8)=51
-5x+30x-24=51
25x-24=51
25x=51+24
25x=75
x=75/25
x=3
y=10(3)-8
y=30-8
y=22
Here, Original Equation: y = -2x - 5
Compare it with, y = mx + b
So, Slope(m) = -2
Parallel line slope = -2 [ Same ]
Now, y - y1 = m(x - x1)
y - 4 = -2(x + 8)
In short, Your Answer would be Option B
Hope this helps!
