given f(x)=x^3+x^2-x what is f(4)
Answer:
76
Step-by-step explanation:
Plug 4 in for each x
Answer:
76
Step-by-step explanation:
given f(x)=x^3+x^2-x what is f(4)
whenever u see f(4) it is telling you that whenever you see an x you would replace it with a 4 so you start substituting the x for 4's or replacing them (same thing XD) 4^3+4^2-4 4 times 4 times 4 = 64 + 4 times 4 = 16
64 + 16 - 4 = 76
This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions. Recipe: Serves 8 400 g oats 1.2 l milk 40 g sugar
Answer:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar
Step-by-step explanation:
This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions.
The ingredients for the recipe = Oats, Milk, Sugar
Hence:
For Oats
8 portions of porridge = 400g of oats
5 portions of porridge = x
Cross Multiply
8x = 5 × 400
x = 5 × 400/8
x = 250g of oats
For Milk
8 portions of porridge = 1.2 L of milk
5 portions of porridge = x
Cross Multiply
8x = 5 × 1.2
x = 5 × 1.2/8
x = 0.75 L of milk
For sugar
8 portions of porridge = 40g of sugar
5 portions of porridge = x
Cross Multiply
8x = 5 × 40
x = 5 × 40/8
x = 25g of sugar
Hence:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar

What equation in slope intercept form represents the line that passes through the two points?
(5,7), (6,-2)
Answer:
[tex]y = -9x +52[/tex]
Step-by-step explanation:
Given
[tex](x_1.y_1) = (5,7)\\[/tex]
[tex](x_2,y_2) = (6,-2)[/tex]
Required
Determine the equation in slope intercept form
First, we calculate the slope of the line:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
This gives:
[tex]m = \frac{7 - (-2)}{5 - 6}[/tex]
[tex]m = \frac{7 +2}{-1}[/tex]
[tex]m = \frac{9}{-1}[/tex]
[tex]m = -9[/tex]
Th equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - 7 = -9(x - 5)[/tex]
Open bracket
[tex]y - 7 = -9x +45[/tex]
Make y the subject
[tex]y = -9x +45+7[/tex]
[tex]y = -9x +52[/tex]
Solve the equation for x.

What is the rate of change of the following equation? y = -5/3x
Answer: -5/3
Step-by-step explanation:
In an equation y = mx + b, m is the value of the slope. The slope is the same as the rate of change. In this case, m = -5/3, thus the rate of change is -5/3.
The graph below represents one function, and the table represents a different function. How are the functions similar? How are they different?
Answer:
Step-by-step explanation:
they both go thur the point (0,-4) so they both have the same b in the slope intercept from of y =mx +b
but.. they have a different slope... m , the graph has a slope m of 4/3 while the table has a slope of 1 , both positive.. :)
The equation given by the graph is y = (4/3)x - 4 while the table is y = x - 4. Both equation have a y intercept of -4.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the point (3, 0) and (0, -4):
y - 0 = [(-4 - 0)/ (0 - 3)](x - 3)
y = (4/3)x - 4
From the table using (0, -4) and (2, -2):
y - (-4) = [(-2-(-4))/(2-0)](x - 0)
y = x - 4
The equation given by the graph is y = (4/3)x - 4 while the table is y = x - 4. Both equation have a y intercept of -4.

Explain.
Answer:

Step-by-step explanation:
Solve for x:
Apply the distributive property: -2x + -6 = -22Simplify: -2x - 6 = -22Add 6 to each side, so it now looks like this: -2x = -16Divide each side by -2 to cancel out the -2 next to x. It should now look like this: x = 8Apply the value of x to 4x:

Answer:
(d) 1 mile = 10 blocks
Step-by-step explanation:
The ballpark is 8 blocks west and 15 blocks north of Jeff's home. The Pythagorean theorem tells us the straight-line distance is ...
d² = 8² +15² = 64 +225 = 289
d = √289 = 17 . . . blocks
The problem tells us this represents 1.7 miles, so the proportion is ...
blocks/miles = 17 blocks/(1.7 miles) = 10 blocks/mile
The map scale is 1 mile = 10 blocks.

The graph shows the distance Kerri drives on a trip. What is Kerri's speed?
Driving Time and Distance
A. 25 miles per hour
B. 60 miles per hour
C. 75 miles per hour
D. 50 miles per hour
Answer:
Kerri's speed = 50 mile per hour. Therefore option (D) is true.
Step-by-step explanation:
Given the distance-time graph
It is clear from the distance-time graph that:
at Time = 1 hour, Distance = 50 milesat Time = 2 hours, Distance = 100 milesso the two points on the distance-time graph is:
(1, 50)(2, 100)Finding the slope between the points to determine the speed.
Please note that the slope between the points represents the speed or rate of change.
Speed = Rate of change = y₂-y₁ / x₂-x₁
= 100 - 50 / 2-1
= 50 / 1
= 50 miles per hour
Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.

Answer:
-7 =k
Step-by-step explanation:
y = 3x + k
Substitute 3 in for x and 2 in for y
2 = 3*3+k
2 = 9+k
Subtract 9 from each side
2-9 = k
-7 =k
