22.25
multiply them by each other and you will get your answer 22.25
Y = 0.95x + 7.95
26 = 0.95x + 7.95
Solve for x
26-7.95 =0.95x
18.05/0.95 = x
X = 19 songs
ANSWER: D. 138
EXPLANATION:
6c^2-5d+8 when c=5 and d=4
=6x5^2-5x4+8
=6x25-5x4+8
=150-20+8
=138
Hope it helps!
Answer:
(-1,3)
Step-by-step explanation:
Graph the given system of equations
y=-x+2
make a table for each equation to graph it
Lets assume some value for x and find out y
x y=-x+2
-1 -(-1) + 2= 3
0 0+2 = 2
1 -1+2 = 1
Now make a table for second equation
y= 4x+7
Lets assume some value for x and find out y
x y= 4x+7
-1 4(-1) + 7= 3
0 4(0) + 7 = 7
1 4(1) + 7 = 11
The graph is attached below
Solution is (-1,3)
Answer:
In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.
