Replace a and b with their number value:
2a^2 + 5b = 2(3)^2 +5(4)
do the 3^2 first: 3^2 = 9
so now you have 2(9) +5(4)
now multiply both sets of numbers: 2 x 9 = 18 and 5 x 4 = 20
now add them:
18 +20 = 38
The answer would be C. 14.4
The answer is 3. Point and line symmetry
Answer:
It depends on what teacher you have.
Step-by-step explanation:
Both are very important.
Answer:
no solutions
Step-by-step explanation:
The lines are parallel since they have the same slope
y = mx+b where m is the slope
They have different y intercepts (b)
The will never intersect so they have no solutions
