Hey there! :)
Answer:
a. 3
b. -22
c. -2
d. -2
e. 5a + 8
f. a² + 6a + 3
Step-by-step explanation:
Calculate the answers by substituting the values inside of the parenthesis for 'x':
a. f(1) = 5(1) - 2 = 3
b. f(-4) = 5(-4) - 2 = -22
c. g(-3) = (-3)² + 2(-3) - 5 = 9 - 6 - 5 = -2
d. g(1) = 1² + 2(1) - 5 = 1 + 2 -5 = -2
e. f(a+ 2) = 5(a+2) - 2 = 5a + 10 - 2 = 5a + 8
f. g(a + 2) = (a + 2)² + 2(a + 2) - 5 = a² + 4a + 4 + 2a + 4 - 5 =
a² + 6a + 3
Answer:
The correct equitation is 60=\frac{3}{5}\times10060=

Step-by-step explanation:
To determine:
A flower show has an inventory of 60 tulips and 100 roses?
Information Fetching and Solution Steps:
A flower show has an inventory of
60 tulips
100 roses
So,
60=\frac{3}{5}\times10060=
5
3
×100
or
100=\frac{5}{3}\times60100=
3
5
×60
Other options can not be true as they do not satisfy the equation. For example,
60 = 3\times 10060=3×100 can not be true as the L.H.S ≠ R.H.S
Therefore, the correct equitation is 60=\frac{3}{5}\times10060=

×100 OR 100=\frac{5}{3}\times60100=

Answer:
Step-by-step explanation:
Let x and y represent amounts invested at 6% and 9%, respectively.
y = 3x +58 . . . . . . . the amount invested at 9%
0.06x +0.09y = 1097.19 . . . . . . total interest earned
__
Substituting for y, we have ...
0.06x +0.09(3x +58) = 1097.19
0.33x + 5.22 = 1097.19 . . . . . . . . . simplify
0.33x = 1091.97 . . . . . . . . . . . . subtract 5.22
x = 3309 . . . . . . . . . . . . . . . . divide by 0.33
y = 3(3309) +58 = 9985
$3309 is invested at 6%; $9985 is invested at 9%.
