Answer:
1.Solve the system of equations.
y = 2x^2 - 3
y = 3x - 1
a. no solution
b. (-1/2, 5), (2, -5/2)
c. (-1/2, -5/2), (2,5)
d. (1/2, 5/2), (2, 5)
2.how many real number solutions does the equation have 0 = -3x^2 + x - 4
a. 0
b. 1
c. 2
d. 3
3. solve the equation by completing the square. If necessary round to the nearest hundredth.
x^2 - 18x = 19
a. 1; 19
b. -1; 19
c. 3; 6
d. -3; 1
4. solve. x^2 - 81 = 0
a. 0
b. -9
c. -9, 9
d. 9
5. which model is most appropriate for the data shown in the graph below? (need wedsite to know the problem)
a. quadratic
Your answer would eventually be 10 doubled would be 20, 5 doubled would be 10 you multiply by 2
$540
6% = .06
“of” = multiply
so 6% of 9000 can be written as .06 x 9000 , which is 540

Answer:
(Choice A)
-4(3e + 4)
Step-by-step explanation:
This is the only answer that makes sense:
-7 - 12e - 9 [Distribute the 3 amongst all the other terms in parentheses]
Then you combine like-terms:
-16 - 12e
Finally, you factor out the Greatest Common Factor [GCF]:
-4[4 + 3e]
12e is NOT an option, so you are left with (Choice A).

Answer:
D
Step-by-step explanation:
Given that the dimensions of a solid are in proportion a : b, then
then the ratio of the area is a² : b²
Thus
scale factor = , then
area factor = = → D
