The function f(x) represented by the straight line in the graph is
and f^-1(x) is
Answer:
f(x)=5x-2 f(x)^-1= (x+2)/5
Step-by-step explanation:
slope is 5 y intercept=-2
y=5x-2
for f(x)^-1 insted x write y so x=5y-2
x+2/5=y
pls help me with these
Answer:
18= -6x+11
19= 2(x+1)

Armando used algebra tiles to represent the product 3 x (2 x minus 1). An algebra tile configuration. 3 tiles are in the Factor 1 spot and are labeled + x. 3 tiles are in the Factor 2 spot: 2 are labeled + x and 1 is labeled negative. 15 tiles are in the Product spot: 2 are labeled + x squared, 4 are labeled + x, 1 is labeled negative x, and 4 are labeled negative. Which is true regarding Armando’s use of algebra tiles? He used the algebra tiles correctly. He did not represent the two original factors correctly. The signs on some of the products are incorrect. Some of the products do not show the correct powers of x.
Answer:
Some of the products do not show the correct powers of x.
Step-by-step explanation:
From the picture,
3x(2x - 1) = 6x² - 3x
The correct display on the tile should look like this :
_____+x ______ +x ______ +x
+x __ +x² ______+x² ______+x²
|
+x__ +x² ______ +x² ______+x²
|
- ___ -x _______ -x _______-x
+6x² - 3x
When rolling a die and flipping a penny, what is the P(4, H)? Make a table or diagram to help get your result.
P(4, H) =
Answer:
P(4, H) = 1/12
Step-by-step explanation:
Here we have two events, let's count the number of outcomes in each one of them.
Rolling a die.
Here we have 6 possible outcomes (1, 2, 3, 4, 5, 6)
Flipping a penny.
Here we have two possible outcomes (Heads = H, Tails = T)
The total number of outcomes in the combined event will be equal to the product between the number of outcomes for each event, so we have a total of:
6*2 = 12 events, that have the same probability.
We want to find P(4, H)
This is the probability of rolling a 4 in the die and heads in the penny.
This is one outcome, and we have a total of 12 outcomes (all with the same probability)
Then the probability of each event is equal and should be 1/12 (one over the number of possible outcomes)
We can conclude that the probability P(4,H) = 1/12
What is the volume ?
Help !!!
Answer:
210 m³Step-by-step explanation:
This is a triangular prism
The volume is:
V = BhV = 1/2*10*6*7 = 210 m³Answer:
Solution :-Volume = ½ × b × h
Volume = ½ × 6 × 10 × 7
Volume = 3 × 10 × 7
Volume = 210 m²

Mike is driving a Toyota Camry. He’s inflated his tire to the dealer-recommend level of 32 PSI. At what speed will Mike’s car start hydroplaning? With what tire pressure would his car start hydroplaning at 45 miles per hour? Use the formula v=10.35 square root p
Answer:
Part A
A speed of approximately 58.55 mph
Part B
A pressure of approximately 18.9 psi
Step-by-step explanation:
Part A
The parameter for the car are;
The tire pressure, p = 32 psi
The given equation determined for the speed, 'v', when a car will start hydroplaning is presented as follows;
v = 10.35·√p
Where;
v = The speed at which the car is moving when it will hydroplane in mpj
p = The pressure in the tire in psi
The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi is therefore;
v = 10.35 × √(32 psi) ≈ 58.55 mph
The speed at which hydro planning will start in Mike's car that has a tire pressure of 32 psi, v ≈ 58.55 mph
Part B
When a car is moving at, v = 45 mph, we have;
v = 10.35·√p
∴ The pressure in the car tire, p = (v/10.35)²
∴ at p = 45 mph, we have;
p = (45 mph/10.35)² ≈ 18.9 psi
The tire pressure at which Mike's car start hydroplaning, p ≈ 18.9 psi
Which of the following is an example of scale?
O 0.25 inches = 1 foot
O 26 feet x 19 feet
O 12 inches in 1 foot
Room holds 1427 rubber ducks
Pls help me :3
Answer:
12 inches in 1 foot
Step-by-step explanation:
In this problem, we need to find an example that is a scale.
There must be a relation between two units.
There are many types of units of lengths. These can be metre, cm, mm, foot, inches.
The relation between inch and foot is given by :
1 foot = 12 inch
So, we can say there are 12 inches in 1 foot.
Hence, the correct option is (c).

Answer:
80%of 25 is 20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
To solve we must first find what 80% is in decimal form.
to do this we can move the decimal place to the left 2 spots
80% ---> 0.80
We can now multiply this decimal by 25
25 × 0.80 = 20
Please help me out with this no links and no stealing points
Answer:
TQ = 24
Step-by-step explanation:
Δ RST and Δ RPQ are similar, thus ratios of corresponding sides are equal, that is
[tex]\frac{RS}{RP}[/tex] = [tex]\frac{RT}{RQ}[/tex] , substitute values
[tex]\frac{15}{35}[/tex] = [tex]\frac{18}{RQ}[/tex] ( cross- multiply )
15 RQ = 630 ( divide both sides by 15 )
RQ = 42
Then
TQ = RQ - RT = 42 - 18 = 24
Carol is comparing two rectangular tiles for a flooring project. The blue tile is 8 centimeters long and 6 centimeters wide. The yellow tile is is 70 milimeters long and 68 milimeters wide. Which tile covers the greater area? How much greater is the area. Use the sentence frame to answer.=: The_____ Tile covers more area by ________.
Answer:
The Blue Tile covers more area by 40 mm^2
Step-by-step explanation:
convert centimeter to millimeters
1cm = 10 mm
(6 x 10) by (8 x 10)
Area of a rectangle = length x breadth
60 x 80 = 4800
70 x 68 = 4760
difference = 4800 - 4760 = 40

label them linear or nonlinear.
1.) y= 3x^3 - 3
2.) y= 8.75x
3.) y= 10/x
Answer:
y=8.75x is the only linear
Step-by-step explanation:
it is single degree monomial. 1) isn't linear beacuse it is a degree 3 polynomial 3) isn't linear because it isn't a polynomial (polynomials can't have variables in the denominator)
