what is the y - intercept
Answer:
The y- intercept is 1
Step-by-step explanation:
Since the line crosses the y-axis at 1, the y-intercept is 1. Like the x-intercept. The line crosses the x-axis at um.. I would say about -1.5, so the x-intercept is -1.5.

Calculate the slope of a line that passes through the following two points.
(5,-2) and (4, -8)
help please it’s due tonight
Answer:
the slope is 6 (6/1)
Step-by-step explanation:
Use the slope formula: y2-y1/x2-x1 ( i did the one that was further to the right ats the second pair rather than the order that you put it in)
Answer:
Yo, the slope of the line is 6 yo!
Step-by-step explanation:
You see, to find the slope of 2 points, Here's what ya do little fella: Pick any y-coordinate point(-2) or (-8). When you do, subtract -2 and -8 so in this case, -y - (-x) = -y + x. So, when done correctly, you get 6 because -2 - (-8) is equal to -2 + 8. Ya go to the x-coordinate. If you subtracted -8 from -2, you have to subtract 4 from 5. If you also subtracted -2 from 8, you have to subtract 5 from 4. So, it has to be in order. 5 - 4 = 1. So then, you divide your answer 6/1 = 6. So 6 is the slope people.

The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. What percent represents the amount of paper used this month? *
Answer:
You didn't include any image here, but numerically, the amount of paper consumed this month is 125% compared to last month.
If last month's consumption is represented by 4 equal shapes, then the current month's consumption will be 5 shapes.
If last month's consumption is represented by 8 equal shapes, then the current month's consumption will be 10 shapes.
this pattern keeps repeating.

Answer:
The answer is 144.
Step-by-step explanation:
The question said 6 gallons of water comes out every minute. So, if you multiply 6x24 you get the answer of 144.
Find the value of x. Then find the measure of each labeled angle
Answer:
x = 109
Top Right Angle = 109
Bottom Right Angle = 71
Step-by-step explanation:
Notice the two right angles on the left and recognize that the figure is a a quadrilateral (4 sides). That means it adds up to a total of 360 degrees.
(x-38) + x + 90 + 90 = 360
2x + 142 = 360
2x = 218
x = 109
(x - 38) = (109 - 38)
71 degrees for bottom right angle
109 for top right angle

A park is showing a movie on the lawn. The base of the screen is 6 feet off the ground and the screen is 22 feet high (see figure).
Answer:
A. 61.82°;
15.64°
B. 33.37°
Step-by-step explanation:
A.
✍️Angle of elevation from 15 ft:
A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 15 ft
Thus, we would have:
[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{15} [/tex]
[tex] tan(\theta) = 1.8667 [/tex]
[tex] \theta = tan^{-1}(1.8667) [/tex]
[tex] \theta = 61.82 [/tex] (2 d.p)
✍️Angle of elevation from 100 ft:
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 100 ft
Thus, we would have:
[tex] tan(\theta) = \frac{opp}{adjacent} = \frac{28}{100} [/tex]
[tex] tan(\theta) = 0.28 [/tex]
[tex] \theta = tan^{-1}(0.28) [/tex]
[tex] \theta = 15.64 [/tex] (2 d.p)
B.
✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:
Adjacent length = your distance from the screen = x
Opposite length = 22 + 6 = 28 ft
Angle of elevation = 40°
Tge trigonometric ratios formula to use would be:
[tex] tan(\theta) = \frac{opp}{adjacent} [/tex]
Plug in the values
[tex] tan(40) = \frac{28}{x} [/tex]
Multiply both sides by x
[tex] x*tan(40) = 28 [/tex]
Divide both sides by tan(40)
[tex] x = \frac{28}{tan(40)} [/tex]
[tex] x = 33.37 [/tex] (2 d.p)
What is the correct order of the steps used to derive the identity?
A.) 4, 3, 5, 1, 2
B.) 4, 5, 3, 1, 2,
C.) 3, 4, 5, 1, 2
D.) 3, 4, 1, 5, 2
The correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2
How to determine the correct order of step?The trigonometry identity is given as:
tan(2x)
When the tangent formula is applied, we have:
[tex]\tan(2x) = \frac{\sin(2x)}{\cos(2x)}[/tex] --- step 4
Expand sin(2x) and cos(2x)
[tex]\tan(2x) = \frac{2\sin(x)\cos(x)}{\cos^(x) - \sin^2(x)}[/tex] --- step 3
The option from the list that obey the above order is (a) 4, 3, 5, 1, 2
Hence, the correct order of the steps used to derive the identity is (A.) 4, 3, 5, 1, 2

Maya is going to an amusement park. The price of admission into the park is $10, and once she is inside the park, she will have to pay $2 for every ride she rides on. How much money would Maya have to pay in total if she goes on 15 rides? How much would she have to pay if she goes on rr rides?
cost for r rides
cost for 15 rides
Answer:
The cost of r rides = 2r + 10
The cost of 15 rides = $40
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the rate of changeb is the initial amountAssume that the cost of r rides is c
∵ The number of the ride is r
∴ x = r
∵ The cost of r rides is c
∴ y = c
∵ The price of admission into the park is $10 ⇒ initial amount
∴ b = 10
∵ She will have to pay $2 for every ride ⇒ rate of change
∴ m = 2
→ Substitute them in the form of the equation above
∴ c = 2r + 10
∴ The cost of r rides = 2r + 10
∵ She goes on 15 rides
∴ r = 15
→ Substitute it in the form of the equation
∵ c = 2(15) + 10
∴ c = 30 + 10
∴ c = 40
∴ The cost of 15 rides = $40

Answer:
x = 57, x = 111
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + 67 + 56 = 180
x + 123 = 180 ( subtract 123 from both sides )
x = 57
---------------------------------------------------------------------
Similarly
x + 47 + 22 = 180
x + 69 = 180 ( subtract 69 from both sides )
x = 111
We can say that:
In the first triangle, x = 57°In the second triangle, x = 111°Let's go!We must know that the sum of all the internal angles of a triangle is equal to 180°. So, just solve an equation to determine x in each triangle.
First triangle:67 + 56 + x = 180 → Sum:123 + x = 180 → We move 123 to the other side, changing its signal.x = 180 - 123 → Subtract:x = 57°Second triangle:22 + 47 + x = 180 → Sum:69 + x = 180 → We move 69 to the other side, changing its signal.x = 180 - 69 → Subtract:x = 111°________________
