Answer:
After solving we get (f.g)(5)=-115
But the correct option is not given in the question.
Step-by-step explanation:
We are given:
[tex]f(x) = 4x+3\\g(x)=-2x+5[/tex]
We need to find (f.g)(5)
First we will multiply f and g to find (f.g) i.e
[tex](f.g)(x)= f(x) \times g(x)\\(f.g)(x) = (4x + 3)(-2x + 5)\\(f.g)(x)=4x(-2x+5)+3(-2x+5)\\(f.g)(x)=-8x^2+20x-6x+15\\(f.g)(x)=-8x^2+14x+15\\[/tex]
Now putting x=5
[tex](f.g)(x)=-8x^2+14x+15\\Put \ x=5\\(f.g)(5)=-8(5)^2+14(5)+15\\(f.g)(5)=-8(25)+70+15\\(f.g)(5)=-200+70+15\\(f.g)(5)=-115[/tex]
So, after solving we get (f.g)(5)=-115
But the correct option is not given in the question.
What is the equation!!
Answer:
y = -5x - 2
Step-by-step explanation:
We have to use slope intercept form which is y = mx + b
mx is the slope and b is the y intercept. Let's start with the y intercept. The y intercept on this graph is -2 so lets see what it looks like to far
y = mx - 2
Next, we find the slope which is -5
y = -5x - 2
Answer:
y=-5x+-2

Answer:
C. x = 150
Step-by-step explanation:
This shape has 6 sides and vertices which represents a hexagon. A hexagon has a total of 720°.
We can make an equation and solve for x.
90 + 120 + 112 + 118 + x + 130 = 720
570 + x = 720
x = 150

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week.

Which function is the inverse of h(x) = 18x+7/3?
Answer:
f^-1 (x)= x/18 - 7/54
Step-by-step explanation:
The inverse function of h(x) is x/18 - 7/54
What is inverse function?The inverse function is defined as a function obtained by reversing the given function.
Given function h(x) = 18x+7/3
Let g(x) function is the inverse function of h(x)
Suppose y = h(x)
y = 18x+7/3
y-7/3 = 18x
y/18 - 7/54 = x
g(x) = x/18 - 7/54
Hence g(x) = x/18 - 7/54 is the inverse function of h(x)

Answer:
y = -3x -2 ( this is only for 5 )
Step-by-step explanation:
Step 1:
First, we need to understand that lines that are perpendicular have slopes that are opposites and reciprocals of each other.
Step 2:
So our initial equation is 2x-6y= 10. We want to rearrange this so that it is in slope-intercept form: y= 1/3x -(10/6). In this form, we can derive the slope of our new line. Because the slope is 1/3, our new slope is -3 ( based on step 1 ).
Step 3:
Now that we have the slope of our new line, we can use the point-slope formula to get our specific line that passes through ( 2, -8 ).
y - y1 = m( x - x1 )
y- ( -8 ) = -3( x - 2 )jhvjjfjhjfhcgch
y + 8 = -3x + 6
y = -3x -2 !

Explain why 3 : 2 and 9 : 8 are not equivalent ratios.
Answer:because 2 can’t go into 9 and 8 can’t go into 3
Step-by-step explanation
-
The ratio shows how many times one value is contained in another value.
3/2 ≠ 9/8
The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
3:2 and 9:8
We will simplify it in its simplest form.
3:2 = 3/2
This is the simplest form.
9:8 = 9/8
This is in its simplest form.
So,
3/2 is not equal with 9/8
If the two ratios are the same we can call them equivalent ratios.
Thus,
3/2 ≠ 9/8
The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios.

What value of x would make 3x-9 equals to 39
Answer:
x=16
Step-by-step explanation:
3 times 16 equals 48 minus 9 equals 39
Answer:
16
Step-by-step explanation:
To solve the equation you must isolate the variable.
3x-9=39
So first, add 9 to both sides
3x-9+9=39+9
3x=48
Then divide both sides by 3
3x/3=48/3
x=16
