Answer:
A. Yes, because it passes the vertical line test.
Step-by-step explanation:
The vertical line test requires you to draw a vertical line through any part of the graph. If the line intersects the graph at only one point, the graph represents a function. This graph passes that test. As for the other answer choices, the "horizontal line test" is not a way to see if a graph represents a function. I hope this helps :))
Answer:
A. Yes, because it passes the vertical line test.
Step-by-step explanation:
The vertical line test states that you can draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function. In this case, the line doesn't intersect the graph more than once.

Answer:
A
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x , y ) → (- y, x ) , thus
X(1, - 1 ) → X'(1, 1 )
Y(3, 4 ) → Y'(- 4, 3 )
Z(5, - 1 ) → Z'(1, 5 ) → A
Answer:
A
Step-by-step explanation:
X(1, - 1 ) → X'(1, 1 )
Y(3, 4 ) → Y'(- 4, 3 )
Z(5, - 1 ) → Z'(1, 5 ) → A
HELP! Point A is located at (3, -1). It is moved 5 units to the left and 4 units up. Its new coordinates are:
Answer: (-2,3)
Explanation:
Subtract 5 from the x coordinate to move the point five units to the left. We go from (3,-1) to (-2,-1) after doing this.
Next up, add 4 to the y coordinate to shift the point up four units. We go from (-2,-1) to (-2,3)
===========================================================
Explanation:
Subtract 5 from the x coordinate to move the point five units to the left. We go from (3,-1) to (-2,-1) after doing this.
Next up, add 4 to the y coordinate to shift the point up four units. We go from (-2,-1) to (-2,3)
See diagram below. Point A is the initial point, B is the second step, and C is the final destination.
-----------
Another way to write out the steps is to use the transformation rule below
[tex](x,y) \to (x-5, y+4)\\\\(3,-1) \to (3-5, -1+4)\\\\(3,-1) \to (-2, 3)\\\\[/tex]
What is m∠A? Enter your answer in the box.
Answer:
∠A is 118 degrees
Step-by-step explanation:
every triangle is 180 degrees
(3x+13) + (x-8) +(x) = 180
simplify
5x + 5 = 180
-5 = -5
5x = 175
175 divided by 5 is 35
so x= 35
∠A= 3(35) + 13
3 times 35 is 105
105 + 13 = 118
so ∠A is 118 degrees

The probability of rain for the day of the race is 62%.
(a) What is the probability that it does not rain on the day
of the race?
Runners who complete the race in 2 hours 15 minutes or less
get a gold medal.
Bradley completed the race in 2 hours 13 minutes 22 seconds.
(b) Work out the difference between 2 hours 15 minutes,
and 2 hours 13 minutes 22 seconds.
a) 100%-62%=38%
b) 2h 15m- 2h 13m 22s= 15m- 13m 22s= (14m- 13m)+ (1m- 22s)= 1m+ 38s= 1m 38s

A typical dove weighs 345g. A typical duck weighs 1.2kg. What is the difference, in grams, of the weights of a duck and a dove?
Answer:
855 grams
Step-by-step explanation:
First convert the 1.2kg into grams.
1.2kg=1200 grams.
Now we have equal units of measurement. We then subtract: 1200g-345g=855g

Which equation represents h(x)?
Answer: The second choice: h(x) = (f(x))(g(x))
Step-by-step explanation:
f(x) = -15
g(x) = 15
h(x) = -225
-15 * 15 = -225
Therefore, h(x) is the distribution of f(x) and g(x).
Elise says, "If you subtract 16 from my number and multiply the difference by - 7, the result is
-154” what is Elise’s number?
Answer:
-6
Explanation:
Elise's number is x.
If you subtract 16 from her number -> x-16
and multiply the difference by 7 -> 7(x-16) = -154
Elise's number is -154/7+16 = -6

Anita has two options for how to invest $1,000. Plan A: put the 1,000 in an account that pays $100 per year. Plan B: put the 1,000 in an account that pays 5 percent interest per year. What statement is true? Plan A will be worth more than plan B after two years. Plan A will be worth more than plan B after one year. Plan B will be worth more than plan A after three years. Plan B will be worth more than plan A after four years.
Answer:
True Plan A will be worth more than plan B after two years.
True Plan A will be worth more than plan B after one year.
False Plan B will be worth more than plan A after three years.
False Plan B will be worth more than plan A after four years.
Step-by-step explanation:
plan A proves 10% Standard interest as it is $100 every year
plan B proves $50 per year Standard interest and may increase if this was CI interest as it may include interest on interest but nothing was mentioned that Plan B was CI type interest or any different from plan B type.
Because of this we can only agree option 1+2 out of 1-4 is true.
Oil prices are projected to increase by 125% by next August. A quart of oil currently costs $1.25. What is the projected cost of a gallon of oil next August? Round your answer to the nearest hundredth.
Answer:
$2.81
Step-by-step explanation:
1.25 is 100% of the price
125% + 100% = 225%
x = price by august
x = 225% (1.25)
225% = 2.25
2.25(1.25) = 2.8125 ≈ $2.81
Another way to see it:
[tex]\frac{1.25}{x}[/tex] = [tex]\frac{100}{225}[/tex]
225(1.25) / 100 = 2.8125
Answer:
11.25

Find the square number 7, 12, 20, 25, 27
Joe took $12 to the arcade. Each game cost $.50 to play. This situation can be modeled with the equation y + -.50 x+ 12. This represents the relationship between money Joe has remaining, y, and the number of games he plays, x. Use the function to determine the x-intercept.
State the Domain and Range for this equation in the context of the problem scenario?
Answer:
x-intercept: x=24
DOMAIN: (0,24) where x∈Natural Numbers
RANGE: (0,12) where y∈Natural Numbers
Step-by-step explanation:
Remain money = y
Number of games = x
Given function:
[tex]y=12-0.5x\\[/tex]
x-intercept:x-intecept is the value of x where y becomes zero.
Substitute y=0 in the given equation:
[tex]0=12-0.5x\\0.5x=12\\x=\frac{12}{0.5}\\x=24[/tex]
Domain:Domain is a set of all possible values of x.
x= No. of games (So x cannot be negative)
y= Remain Amount (So y cannot be negative)
So the minimum value of x is 0 because x cannot be negative.
Maximum value of x is the value for which y doesn't become negative. For any value of x>24, y <0 which is not possible.
So maximum value of x is 24
DOMAIN: (0,24) where x∈Natural Numbers
Range:
Range is a set of all outcomes of y for all possible values of x.
For x=0 , y =12
for x=24 , y = 0
So
RANGE: (0,12) where y∈Natural Numbers

Step-by-step explanation:
a pair of shoes is originally priced at 120 It is on sale for 35% off . Find the total percent that you would pay
Step-by-step explanation:
If the discount is 35% off. then the new price is 65% of what the old price is. So we multiply 120 x .65 = 78
Answer:
You pay 65% which is $78
Step-by-step explanation:
You'd pay 65% of the original price.
65% of the original price is 78
To do this you multiply 65% by 120
