The value of the dependent variable y is always four times(one fourth or four times) the value of the independent variable x. Show me how.
Pls help
Answer:
y=4x
Step-by-step explanation:
when x is 1 the y value is 4. this means each times x moves 1 across the x axis, the y value will go up 4 on the y axis. this means the equation has a slope of 4

Answer:
reflection across y-axis
Step-by-step explanation:
the shape flipped over vertically (y axis) and not horizontally (x axis), so it reflected across the y-axis and not the x-axis
Answer:
The answer is D) Reflection across y-axis.
Step-by-step explanation:
You can tell by looking at the labeled points that the shape was reflected that it was reflected across the y-axis. Think of it like a mirror: the image flipped across the y-axis, so we know that is the right answer.

Answer:
x = 12
Step-by-step explanation:
The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{x}{9}[/tex] = [tex]\frac{4}{3}[/tex] ( cross- multiply )
3x = 36 ( divide both sides by 3 )
x = 12
You take your brother and sister to a ballgame and buy them hats and shirts. The
shirts cost $11 each. Your brother wants 3 shirts and 4 hats while your sister
wants 2 hats and 2 shirts. If your total bill was $115, how much is a hat? *
Answer:
10$ per hat
Step-by-step explanation:
11$ x 5(shirts) = 55
115-55=60
60$ divided by 6(hats) = 10$ per hat

The measure of an angle is 32.9°. What is the measure of its complementary angle?
Answer: 57.1
Step-by-step explanation: To be complementary the angles have to add up to make a sum of 90.
90 - 32.9 = 57.1
The angles are 32.9 and 57.1.
A gardener will use up to 240 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least four times the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.

The distance y in miles) that Train A travels in x hours is represented by the equation y= 72x is train A or train B faster ?
Answer:
The speed of Train A = 72 miles per hour
The speed of Train B = 68 miles per hour
Therefore, Train A runs faster because the speed of train A is greater than the speed of train B.
Hence, Train A is faster than Train B
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-intercept
Train A)
The distance y (in miles) that Train A travels in x hours is represented by the equation:
y = 72x
comparing with the slope-intercept form of the linear/line equation
So, the rate of change or slope of Train A is: m = 72
As the slope represents the speed of the train.Therefore, the speed of Train A = 72 miles per hour
Train B)
Taking two points from the given graph of Train B
(1, 68)(2, 136)Determining the slope between (1, 68) and (2, 136)
(x₁, y₁) = (1, 68)
(x₂, y₂) = (2, 136)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [136 - 68] / [2 - 1]
= 68 / 1
= 68
So, the rate of change or the slope of the line = m = 68
As the slope represents the speed of the train.Therefore, the speed of Train B = 68 miles per hour
Conclusion:
As
The speed of Train A = 72 miles per hour
The speed of Train B = 68 miles per hour
Therefore, Train A runs faster because the speed of train A is greater than the speed of train B.
Hence, Train A is faster than Train B

find the length of EF in this Pythagorean theorem problem and show work please and thanks you
Answer:
I'm not sure if you can solve this with Pythagorean Theorem because as far as I know, you need sides not angle+side combination. Despite this, let's solve this one using sine law, cosine law or even tangent.
Step-by-step explanation:
[tex] \tan(61) = \frac{length \: of \: df}{24} \\ length \: of \: df = 24 \tan(61) \\ = 43.2971 \\ \\ \cos(19) = \frac{length \: of \: df}{length \: of \: ef} \\ length \: of \: ef \: = \frac{43.2971}{ \cos(19) } \\ = 45.7919[/tex]

HELP!! PLEASE!! HELP!!The following graph shows the relationship between the cost and distance of a taxi ride. What does the y-
intercept on the graph represent?
A. The cost is $2.00 before any miles are driven.
B. The taxi’s speed for the first two miles.
C. The taxi drives two miles before money is charged.
D. The cost of the taxi is $2.00 per mile
Answer:
A.)
Step-by-step explanation:
Hope this helps !
And if you want to can you mark me brainiest
Answer: A. The cost is $2.00 before any miles are driven
=======================================================
Explanation:
x = number of miles driven
y = total cost of driving x miles
When x = 0, the graph shows y = 2. This is shown as the point (x,y) = (0,2). This is the y intercept where the graph crosses the vertical y axis.
When x = 0, the taxi hasn't driven at all. So having y = 2 pair with this x value means that it costs $2 to get into the cab, even if the cab hasn't gone anywhere. This is the initial fee.
------------------------------------
Extra info:
Computing the slope of this line will get you the amount of money per mile charged. In other words, it will give how much extra money you pay per mile on top of the initial $2. In this case, the slope is 9/10 = 0.90, meaning that you pay 90 cents per mile.
The equation of this line is y = 0.90x+2

Debbie bought a computer for 25% off the list price. If the list price is $2,428, how much did Debbie spend?
Given:
Debbie bought a computer for 25% off the list price.
The list price = $2,428
To find:
The amount spend by Debbie.
Solution:
We have,
The list price = $2,428
Money spend by Debbie = List price - 25% of list price
[tex]=2428-\dfrac{25}{100}(2428)[/tex]
[tex]=2428-607[/tex]
[tex]=1821[/tex]
Therefore, the amount spend by Debbie is $1821.
Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in the same direction but at an average speed of 75 km/h. After driving for three hours Huong caught up with Asanji. How long did Asanji drive before Huong caught up?
Answer:
Asanji drove for [tex]5[/tex] hours before Huong caught up
Step-by-step explanation:
Let the time for which Asanji drove alone is "X" hours
Asanji and Huong met after three hours of driving of Huong.
Total time for which Asanji drove [tex]= X+3[/tex] hours
Thus, distance travelled by Asanji in [tex]X+3[/tex] hours is equal to distance travelled by Huong in [tex]3[/tex] hours
[tex]45 ( X+3) = 75 (3)\\[/tex]
On solving the above equation, we get -
[tex]45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2[/tex]
Asanji drove for [tex]3 + 2 = 5[/tex] hours before Huong caught up
