Consider these functions:
f(x) = -1/2x^2 + 5xf(x) = -1/2^2 + 5x
g(x) = x^2 + 2g(x)= x^2 + 2
What is the value of f(g(-2))?
Answer:
Answer is 12
Step-by-step explanation:
f(g(-2))
=f((-2)^2+2)

Valeria has been training for the Charlestown cruisers bike race. The first week she trained, she rode 5 days and took the same two routes each day. She rode and 8 mile route each morning and longer route each evening. By the end of the week, she had ridden a total of 115 miles. How many miles did valeria ride each evening
The number of miles covered every evening obtujwd using a system of equation is 15 miles.
Let the number of miles per evening = m
Number of days = 5 Number of miles per morning = 8 miles Total miles covered = 115 milesUsing the expression below :
Number of days(miles per morning + miles per evening) = 115 miles
5(8 + m) = 115
40 + 5m = 115
5m = 115 - 40
5m = 75
m = 75 / 5
m = 15 miles
Therefore, the Number of miles covered per evening is 15 miles.

Tammy has 35 coins nickels and quarters. In all she has $4.15. How many of each kind of coin does she have
The currency called the U.S dollar can be split into smaller forms or currency value of itself. Examples of these smaller forms are: dimes, nickels, pennies, and quarters.
Tammy has 23 nickels and 12 quarters.
Let's represent the number of:
Nickels = n
Quarters = q
It is important to note that the value of:
1 nickel = $0.05
1 quarter = $0.25
Tammy has 35 coins nickels and quarters. This statement can be represented using an algebraic equation below:
n + q = 35
This can be rewritten as :
n = 35 - q
In all, she has $4.15. This statement can be represented using an algebraic equation below:
0.05n + 0.25q = 4.15
We substitute 35 - q for n in the above equation.
0.05(35 - q) + 0.25q = 4.15
1.75 - 0.05q + 0.25q = 4.15
Collect like terms
- 0.05q + 0.25q = 4.15 - 1.75
0.2q = 2.4
Divide both sides by 0.2
0.2q/0.2 = 2.4/0.2
q = 12
Therefore, the number of quarters Tammy has is 12.
Solving for the number of nickels, we have the equation:
n = 35 - q
n = 35 - 12
n = 23
Therefore, the number of nickels Tammy has is 23.

Help me find x please!!!
Answer:
Step-by-step explanation:
2) 133 + a = 180 {Linear pair}
a = 180 - 133
a = 47
a +b = 180 {linear pair}
47 + b = 180
b = 180 - 47
b = 133
x = b + 30 {Exterior angle property}
x = 133 +30
x = 163
3) m + 35+ 35 = 180 {Angle sum property of triangle}
m + 70 = 180
m = 180 - 70
m = 110
z = 35 {alternate interior angles are congruent}
x = m + z
x = 110 + 35
x = 145

Mr. and Mrs. Smith's children all play different sports. They want to buy a combination of soccer
training sets, which each cost $149, volleyball training set, which each cost $127, and football
training sets which each cost $275. Let s represent number of soccer sets, v represent number of
volleyball sets and frepresent the number of football sets. Which expression represents the total
amount of money the Smiths will spend, before sales tax, based on the number of sports sets they
buy?
Answer:
149sx+127v+275f =
276
Step-by-step explanation:
multiply all the numbers than add you get the answer 149sx+127v+275f
149s + 127v + 275f is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.
What is Expression?An expression is combination of variables, numbers and operators.
The total amount of money the Smiths will spend on the soccer, volleyball, and football training sets can be represented by the expression:
149s + 127v + 275f
Here, 149s represents the cost of s soccer training sets,
127v represents the cost of v volleyball training sets, and
275f represents the cost of f football training sets.
To find the total amount of money the Smiths will spend based on the number of sports sets they buy, simply substitute the corresponding values of s, v, and f into the expression above and simplify.
Hence, 149s + 127v + 275f is expression represents the total amount of money the Smiths will spend, before sales tax, based on the number of sports sets they buy.

Which graph shows y=x^2+3x-4
Answer:
Third graph in the photo
Step-by-step explanation:
x^2+3x-4 can be factored as (x+4)(x-1). When y=0, x must be -4 or 1 to satisfy the equations, and thus the roots of the graph are at x=-4 and x=1. When x=0, y=(4)(-1)=-4. The only graph that satisfies both of these requirements is the third/last one.

Answer:
I believe it's also 74°
Step-by-step explanation:
Because AGF and CGE are congruent,so the angle measurement should stay the same
Answer:
CGE is 74°
Step-by-step explanation:
AGF = FGD
FGD = CGE
AGF = EGB
AGF = 74°
FGD = 74°
CGE = 74°
EGB = 74°
360° is a circle and CGA = BGD
74 + 74 + 74 + 74 + x + x = 360
296 + 2x = 360
2x = 360 - 296
2x = 64
2x/2 = 64/2
x = 32
CGA and BGD are 32
CGE is 74°
