Steps:
Reorder and gather like terms
5a+(2b-3b)+4
Collect coefficients of liked terms
5a+(2-3)*b+4
Calculate the sum or difference
5a-b+4
FINAL Answer: 5a-b+4
Answer:
A, C
Step-by-step explanation:
I had answered this earlier, so you better look back at that question.
To reiterate, use the Pythagorean Theorem a^2+b^2=c^2.
If a^2+b^2=c^2, it is a right triangle.
*remember that squaring a square root results in just the number inside the square root.
Answer:
£90
Step-by-step explanation:
Let M = Malachy's share
and P = Paul's share
and B = Brian's share.
We have three conditions:
(1) M = 2P
(2) P = 3B
(3) M + P + B = 150
Solve for B:
Substitute (2) into (3) (4) M + 3B + B = 150
(5) M + 4B = 150
Substitute (2) into (1) M = 2(3B)
(6) M = 6B
Substitute (6) into (5) 6B + 3B + B = 1 50
(7) B = 15
Solve for P:
Substitute (7) into (2) P = 3×15
(8) P = 45
Solve for M:
Substitute (8) into (1) M = 2×45
M = 90
Malachy gets £90.
Answer:
B) y=2x+3
Step-by-step explanation:
2x+3 2 is the slope it goes up two over one 2/1 or 2 and +3 is where the line intersects the y axis ( -3 would mean that the line intersected at -3 )
