Answer:
This equation has one solution so given statement is true.
Step-by-step explanation:
7a +4 – 2a = 7a + (-20)+4
5a + 4 = 7a - 16
5a - 7a = -16 - 4
- 2a = - 20
a = 10
This equation has one solution so given statement is true.

Answer:
The base = 8 cm and the altitude = 4 cm.
Step-by-step explanation:
b = a + 4 where b = base and a = the altitude.
Area = 1/2 * a * b = 16
Area = 1/2 * a * (a + 4) = 16
1/2 a^2 + 2a = 16
a^2 + 4a - 32 = 0
(a + 8)(a - 4) = 0
a = 4 .
b = 4+4 = 8.
Answer:
f(0)= 3-2^0 --> 3-1 =2
f(-1)= 3 - 2^-1 --> 3 - 1/2 -->5/2 = 2,5
Step-by-step explanation: F(0) means if x=0 so the first you just take x and replace it with 0 and the second you replace x by -1.
Something that is elevated by 0 is always going to be 1
Hope this make sense :)
