Answer:
The first Answer is five because four times five plus ten is 30 and fives times six is 30
The second answer is X equals 3 because if you plug in 11x for y then add that to the existing x you get 12 and if you divide 36 by 12 you get 3
Step-by-step explanation:
Answer:
(5, -1)
Step-by-step explanation:
Midpoint = (x1 + x2 ÷ 2) , (y1 + y2 ÷ 2)
MP= (7 + 3 ÷ 2), (-5 + 3 ÷ 2)
= (10÷2), (-2÷2)
=(5), (-1)
MP= (5, -1)
I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
Answer:
k = 4 units
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
k² + 7.5² = 8.5²
k² + 56.25 = 72.25 ( subtract 56.25 from both sides )
k² = 16 ( take the square root of both sides )
k = 
= 4
Answer:
1.) yes
2.) no
Step-by-step explanation:
1.) Yes
3x - 2y = 1
3(5) - 2(7) = 1
15 - 14 = 1
1 = 1
2.) No
2x + 8y = 26
2(-3) + 8(-4) = 26
-6 - 32 = 26
-38 ≠ 26
