Answer:
Given the proposed interrogate, as well as the graph provided, the correct answer is B. Y = 1/2 x + 4
Step-by-step explanation:
To evaluate such, a comprehension of linear Cartesian planes are obligated:
Slopes = rise/run
X- intercept: The peculiar point in which linear data is observed to intersect the x-axis.
Y- intercept: The peculiar point in which linear data is observed to intersect the y-axis.
Slope: 1/2 as for every individual space endeavored, a space of 2 to the right is required.
Y- intercept: (4,0)
Thus, the ameliorated answer to such interrogate is acknowledged as B. Y = 1/2 x + 4.

Answer: The total amount is $14.99+4.95x.
Step-by-step explanation:
Let the number of songs be 'x'.
Cost of each song = $0.99
Amount paid to join an online music service = $14.99
Number of months = 5
So, According to question, we get that
Total amount =
Hence, the total amount is $14.99+4.95x.
A straight like is 180 degrees since you have 38 and wanna find the one beside it to complete the straight line you take 180-38=142 degrees.
Answer:
45 and 135degrees
Step-by-step explanation:
Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
In trigonometry, cosx = sin(90-x)
Hence:
Cos(8x+21) = sin(90-(8x+21))
Cos(8x+21) = sin(90-8x-21)
Cos(8x+21) = sin(-8x+69)
Substituting into the expression given, :
sin(-8x+69) = sin(-2x+51)
-8x+69 = -2x+51
-8x+2x = 51-69.
-6x = -18.
X = 18/6
X = 3
Since the angles 8x+21
Angle = 8(3)+21
Angle = 45
The angles represented in degrees are 45 and (180-45) = 135degrees
By direct calculation, we will see that the full price of each necktie is $29.
<h3>
How to find the complete price of each necktie?</h3>
Let's say that the full price of each necktie is f.
We know that Will each necktie costed $8 less than the full price, so he paid:
(f - $8) for each one.
Knowing that he bought 7 and paid a total of $147, we know that he paid:
$147/7 = $21
Then we need to solve:
(f - $8) = $21
Solving for f, we have:
f = $21 + $8 = $29.
So the full price of each necktie is $29.
