Answer:
A) 90
Step-by-step explanation:
"The sum of two integers is 23" becomes
a + b = 23
"the positive difference of the same two integers is 13" becomes
a - b = 13 (difference means subtract)
Now solve the system..
a + b = 23
a - b = 13 *use addition or elimination method, since b has opposite coefficients...
2a = 36 ( we add the two equations together)
a = 18 (divide by 2 on both sides)
Since a = 18, 18 + b = 23, gives us b = 5. (18 + 5 = 23)
ab = (18)(5) = 90
I think the answer is D)
Hope this helps!!!!:)
Put the triangle inside of each other lining up the 90° angle corners.
Answer:
m=2
Step-by-step explanation:
6x - 3y + 6 = 0
Subtract 6x from both sides.
-3y + 6 = -6x
Subtract 6 from both sides.
-3y = -6x - 6
Find the GCF of both sides by, which, in this case, is -3. Divide both sides by the GCF, -3.
y = 2x + 2
Since the formula for linear equations is:
y = mx + b , 2 in the slope.
