Answer:
g(7)= -4
Step-by-step explanation:
10-2(7)
10-14
=-4
The value of g(7) is -4.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
g(x) = 10 - 2x
For x = 7,
g(7) = 10 - 2 x 7
g(7) = 10 - 14
g(7) = -4
Thus,
g(7) = -4.

For all values of x, f(x) = x^2 + 1 and g(x) = x-5
(a) Show that fg(x) = x^2 - 10x + 26
(b) Solve fg(x) = gf(x)
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
Step(i):-
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
Step(ii):-
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5

a case of fruit weighs 53 kilogram and another weighs 47 kilograms how much weight must be removed from the first case and placed in the second is that they both equal
a . 2 kilograms
b . 4 kilograms
c . 6 kilograms
d . 8 kilograms
There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Fruit weight = 53 kilograms
And, Another weight = 47 kilograms
Now,
Let number of kilograms weights to remove and add = x
So, We can formulate;
⇒ 53 - x = 47 + x
Solve for x as;
⇒ 53 - 47 = x + x
⇒ 6 = 2x
⇒ 2x = 6
⇒ x = 3
Thus, There are 3 kilograms weight must be removed from the first case and placed in the second is that they both equal.

1. Two linear functions are shown below. Which function has the greater
rate of change?
Answer:
Function A
Step-by-step explanation:
Function A rate of change:
Using two given pairs of values, (4, 32) and (8, 44):
Rate of change = ∆y/∆x
= (44 - 32)/(8 - 4)
= 10/4
Rate of change = ⁵/2
Function B rate of change:
Using two points on the line, (2, 4.5) and (4, 6.5):
Rate of change = ∆y/∆x
= (6.5 - 4.5)/(4 - 2)
= 2/2
Rate of change = 1
Function A has the greater rate of change
Function A has the greater rate of change.
Here, we have,
Function A rate of change:
Using two given pairs of values, (4, 32) and (8, 44):
Rate of change = ∆y/∆x
= (44 - 32)/(8 - 4)
= 10/4
=5/2
Rate of change = 5/2
Function B rate of change:
Using two points on the line, (2, 4.5) and (4, 6.5):
Rate of change = ∆y/∆x
= (6.5 - 4.5)/(4 - 2)
= 2/2
Rate of change = 1
Function A has the greater rate of change.

The scatter plot shows the number of CDs in millions that were sold from 2011 to 2016. Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.
Answer:
slope -intercept form
y = -328.275 x + 3142.15
Step-by-step explanation:
Step(i):-
Given that the points are (2, 2485.6) and (6,1172.5)
The slope of the line
[tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]
[tex]m = \frac{1172.5-2485.6 }{6-2 }[/tex]
[tex]m = - 328.275[/tex]
Step(ii):-
Equation of the straight line passing through the Point (2,2485.6)
[tex]y - y_{1} = m(x-x_{1} )[/tex]
y - 2485.6 = (-328.275)(x-2)
y - 2485.6 = -328.275x+656.55
y = -328.275x+656.55 + 2485.6
y = -328.275 x + 3142.15
Final answer:-
slope -intercept form
y = -328.275 x + 3142.15
