Answer:
It is not a function because there are two different y-
values for a single x-value.
Step-by-step explanation:
x values can repeat, as long as the function passes the vertical line test, you're good

Answer: the pre image is FGH
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The triangle was translated 4 units down.
It can not be A, because it would have needed to be translated up 4 units.
It can't be C, because they are not both images, one is the starting image or the pre-image and the other is after the translation or the image.
D is incorrect because it con be determined.

the function g is a transformation of f if g has a y-intercept at -1 which of the following functions could represent g
9514 1404 393
Answer:
A.
Step-by-step explanation:
The function f has a y-intercept of -5. The function g's y-intercept of -1 is 4 units up from that, so one way to represent g is ...
g(x) = f(x) +4
The required function is g(x) = f(x) + 4. Hence, Correct option is A.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.
According to the graph,
The given curve has y intercept at y = -5.
Which implies that when we add 4 to the function intercept shifts to y = -1 although it is the required intercept of new function g(x).
Thus, the required g is g(x) = f(x) + 4

Harvey flew south 300 miles. He changed planes and then flew east 500 miles. If he travels a straight path back home, how many miles will he fly? Round to the nearest mile.
Answer:
583 miles
Step-by-step explanation:
Let's draw this out (see attachment).
The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 300 and b = 500. Then:
300² + 500² = c²
90000 + 250000 = c²
340000 = c²
c = √340000 ≈ 583.1 ≈ 583 mi
Thus, the answer is 583 miles.

Let x = the length of the shorter piece of rope. x + (1/2)x = 24 (3/2)x = 24 (2/3)(3/2)x = (2/3)(24) x = 16 The lengths of rope are 16 feet and 8 feet. A student solves the problem to the left as shown. Which statements describe the solution? Check all of the boxes that apply.
Answer:
Step-by-step explanation:
Given the question
A rope is 24 feet long. It is cut into two pieces such that one piece is half the length of the other. Find the lengths of the two pieces of rope.
Options
The stated solution is correct (lengths of 16 feet and 8 feet).
Based on the way the variable is defined, the equation should be x + 2x = 24.
The equation is written correctly, but there is an error in solving the equation.
The way the variable is defined, and because x=16, the longer piece of rope would be 32 feet, which is not possible.
2
Let the length of one piece be x (shorter piece) and the other be y.
If the rope is cut into two pieces and 24ft long, then;
x+y = 24.......... 1
If one piece is half the length of the other, then x = y/2..... 2
substitute equation 2 into 1
y/2 + y = 24
take the LCM
y+2y/2 = 24
3y/2 = 24
cross multiply
3y = 48
Divide both sides by 3;
3y/3 = 48/3
y = 16 feet
Since x = y/2
x = 16/2
x = 8 feet
Based on the calculation above, I can conclude that;
- The student stated solution is correct (lengths of 16 feet and 8 feet)
- The way the variable is defined, and because x=16, the longer piece of rope would be 32 feet, which is not possible.
- Based on the way the variable is defined, the equation should be x + 2x = 24.

a) 12%
b) 20%
C) 25%
d) 33%
Answer: C) 25%
Step-by-step explanation:
Please help me it would mean a lot
42.5 i think
The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.
The graph below shows the relationship between time and distance traveled by a race
car moving at a constant rate and at its maximum speed. How long did it take the
race car to travel 480 miles?

0
0.5 1.5 2.5 3.5 4.5 5.5 6.5
Time (hours)
Answer:
t = 4.2 h
Step-by-step explanation:
We can calculate the time taken by the car to travel 400 miles, easily by taking a difference of time in graph between 0 miles and 400 miles value:
t₄₀₀ = 3.5 h - 0 h
t₄₀₀ = 3.5 h
Now, we calculate the constant speed of the car from the following formula:
s = vt
v = s/t
where,
v = velocity of the car = ?
s = distance covered by the car = 400 mi
t = time taken = 3.5 h
Therefore,
v = 400 mi/3.5 h
v = 114.28 mi/h
Now, for this uniform speed the time taken to cover the distance of 480 miles will be:
114.28 mi/h = 480 mi/t
t = (480 mi)/(114.28 mi/h)
t = 4.2 h
-2 -(-4) -2= ?
thx for the answer plz explain when u answer
Answer:
0
Step-by-step explanation:
-2-(-4)-2
We can break down the problem first. The beginning of the problem is...
-2-(-4)
Two negatives make a positive. An equivalent way to say this is
-2+4
-2+4=2
Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!
2-2=0
The answer to this is 0!
I hope you understood the explanation...have an amazing day!!!! :3
Emily wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with a length of 6m and a width of 2m. She decides on a scale of 1cm to 0.5m. If the kitchen door is 1.2m wide, how wide should the door be on the scale drawing? Be sure to include units
Answer:
2.4 cm
Step-by-step explanation:
The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)
She decides to draw 1cm for the original length of 0.5m=50 cm.
For this, the scaled dimension on the drawing=1cm and
the original dimention=50 cm
So, the scale-factor = 1/50.
As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.
So, the scaled width of the door is
[tex]120\times \frac{1}{50}=2.4 cm.[/tex]
Hence, on the drawing, the width of the kitchen door should be 2.4 cm.
On a map to cities are about 50 mm apart if the scale is 1 cm equals 15.5 miles how far apart are the two cities
Given:
On a map to cities are about 50 mm apart.
Scale is 1 cm equals 15.5 miles.
To find:
The distance between two cities.
Step-by-step explanation:
We have,
1 cm = 15.5 miles
It means
10 mm = 15.5 miles [1 cm = 10 mm]
Now,
10 mm on a map = 15.5 miles
1 mm on a map = [tex]\dfrac{15.5}{10}[/tex] miles
= 1.55 miles
50 mm on a map = 50 × 1.55 miles
= 77.5
Therefore, the two cities are 77.5 miles apart.

a = -1/2
Hope this helps :)
Answer:
a = -1/2
Step-by-step explanation:
-1/4a - 4 = 7/4a - 3
-a/2^2 - 4 = 7/ 2^2 a - 3
(-a) - ( 2^2) 4 / 2^2 = 7a/ 2^2 - 3
a = -1/2
I know this confusing but this how I got the answer.

Use the relation 2x+y=10 to find the missing values.
Answer:
x= 5 -y/2
y=10-2x
Step-by-step explanation:
solve for Y solve for X
2x + y= 10 2x+ y=10 subtract y from each side
-2x -2x -y=10 -y
y=10-2x 2x=10 -y
2x/2= 10 -y/2 multiply both sides by 2
x= 5 - y/2
