if (x) = x+8 and g(x) = -4x-3, find (f+ g)(x).
A. (F+ 9)(x) = 5x +11
B. (f+9)(x) = -3x+5
C. (f+ g)(x) = 3x - 5
D. (f+ 9)(x) = -5x - 11
Answer:
Answer=B
(f+g)(x)=-3x-5
Step-by-step explanation:
f(x)=x+8.
g(x)=-4x-3.
(f+g)(x) means f(x)+g(x),So
(x+8)+(-4x-3)
(add all same terms together)
=(x+(-4x))+(8+(-3))
=-3x+5
so,
(f+g)(x)=-3x+5

The graph of f(x)=x2 is horizontally stretched by a factor of 2 and then shifted to the left 2 units and down 4 units. Which equation describes the function g that results?
Using shifting concepts, it is found that function g is given by:
[tex]g(x) = \frac{x^2 - 4x - 12}{4}[/tex]
--------------
Horizontally stretching a function f(x) a units is the same as finding [tex]f(\frac{x}{a})[/tex]Shifting a function f(x) a units to the left is the same as finding f(x - a).Shifting a function f(x) down a units is the same as finding f(x) - a.--------------
The parent function is:
[tex]f(x) = x^2[/tex]
--------------
Horizontally stretching by a factor of 2.
[tex]f(\frac{x}{2}) = (\frac{x}{2})^2 = \frac{x^2}{4}[/tex]
--------------
Shifting left 2 units:
[tex]f(\frac{(x-2)}{2}) = \frac{(x - 2)^2}{4} = \frac{x^2 - 4x + 4}{4}[/tex]
--------------
Shifting down 4 units:
[tex]g(x) = f(\frac{(x-2)}{2}) - 4 = \frac{x^2 - 4x + 4}{4} - 4 = \frac{x^2 - 4x + 4}{4} - \frac{16}{4} = \frac{x^2 - 4x - 12}{4}[/tex]

Bill is a builder.
On Monday he made mortar mix.
He used 24kg of sand and 5 kg of cement.
On Tuesday Bill will make the same type of mortar mix.
He will use 36 kg of sand.
How much cement does he need to make the same type of mortar mix?
Answer:
7.5 kg
Step-by-step explanation:
24 : 5
36 : x
x = 5 × 36 / 24
= 7.5 kg
Bill needs 7.5 kg of cement
Monday:
Sand = 24 kg
Cement = 5 kg
Tuesday:
Sand = 36 kg
Cement = x kg
Ratio of sand to cement
24 : 5 = 36 : x
24/5 = 36/x
Cross product
24 * x = 5 * 36
24x = 180
x = 180/24
x = 7.5 kg

Write it slope intercept form:
Slope= -1 Y intercept= 8
Answer:
y = -x + 8
Step-by-step explanation:
Slope-intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
We are given that the slope is -1 and the y-intercept is 8. We are asked to write the information in slope-intercept form. To do this, lets plug in -1 for m, the slope, and 8 for b, the y-intercept, into the equation for slope-intercept form.
y = mx + b
y = -1x + 8
y = -x + 8
So the slope intercept form would be y = -x + 8.

A. The parent function reflect across x-axis.
What is Function ?A relation between set of inputs & set of outputs is called function. In a function, for each element of input set there is exactly one element of the set of outputs.
What is Parent function ?The simplest form of a family of functions is called the parent function. A family of functions always share same highest degree & shape.
What is Absolute value function ?If a function has an algebraic expression in absolute value symbols, then the function is called absolute value function.
How to describing the transformation ?
The parent function y = |x| always go downwards & hence the curve opened upward.
So, The parent function y = |x| reflect across x-axis.

In the cafeteria, 100 milk cartons were put out for breakfast. After breakfast there were 40 milk cartons left. What is the ratio of milk cartons taken to total milk cartons put out for breakfast.
Answer:
3:5
Step-by-step explanation:
There were 100 milk cartons there and someone took 100-x=40. Add 100 on both sides 40-100=-60 so 60 milk cartons were taken. So the ratio would be 60:100, which can be simplified further 30:50 15:25 3:5.

The most a baker can spend on strawberries is $95.00. Strawberries cost $3.99 per pound, and the produce supplier charges a $15.20 delivery fee. The following inequality, where s stands for the number of pounds of strawberries, represents this situation:
Answer:
3.99s + 15.20 = 95.00
Step-by-step explanation:
you would put 's' next to the 3.99 because that's what your multiplying or having more than 1 of, then you would add the 15.20 because it's just a one time delivery fee.
Answer:
The answer is 20
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:
15 3/4
Step-by-step explanation:
You need to have like denominators before you add so you need to find the LCM (least common multiple) of the two numbers. Then you have to find how much you have to multiply each number by to get the multiple. Then you just have to remember that whatever you do to the bottom you do to the top.
1. 8 1/2 + 7 1/4 This is your equation.
2. 8 2/4 + 7 1/4 The LCM of 2 and 4 is 4. You multiply by two in the bottom to get 4 so you multiply by 2 at the top. (This is talking about the first fraction).
3. 15 3/4 Then you just add as you would normally add without changing the denominators an simplifying if you need to. (You don't need to simplify for this equation).
I hope this helped you.
