Answer:
x=12
Step-by-step explanation:
Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.
Now looking at the question, we know one side is 90 degree since it is a right triangle.
180-90=90
This let us know that the remaining two angles will have to add up to equal to 90 degrees.
2x+1+5x+5=90
First, combine like terms.
7x+6=90
Now we have to get x by itself, subtract 6 on both sides then divide by 7.
7x=84
x=12

Step-by-step explanation:
(3, -1) and (-1, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5+1)/(-1-3)
m=6/(-4)
m= -3/2
Slope-intercept:
y - y1 = m(x - x1)
y + 1 = -3/2(x - 3)
y + 1 = -3/2x + 9/2
y = -3/2x + 7/2
Standard form:
y = -3/2x + 7/2
3x + 2y = 7
2y = -3x + 7

Intercepts:
Write the ordered pair describing the coordinates of each intercept.
1. x-intercept: -6 2. y-intercept: -2.3 3. y-intercept: 3/4
Find the x-intercept and y-intercept for the graph of each equation.
4. y = 3x – 9 5. y = 5x + 10 6. y=1/2 x+4
7. y = 12 – 6x 8. 2y = -6x + 8
Use the x-intercept and y-intercept to graph each equation.
9. y=-1/2 x-3 10. y = 2x + 4
x-intercept: ______ x-intercept: ______
y-intercept: ______ y-intercept: ______
Graph your answers from #4 and #8 from above.
11. y = 3x – 9 12. 2y = -6x + 8
Answers
The y-intercept is the point where the function crosses the y axis at x=0
1. It is an x-intercept, so y = 0. The ordered pair would be (-6, 0)
2. It is a y-intercept, so x = 0. The ordered pair would be (0, -2.3)
3. It is a y-intercept, so x=0. The ordered pair would be (0, 3/4)
To find the x-intercept, set y = 0. To find the y-intercept, set x=0
4. y-intercept: y = 3(0) -9. y = -9 The y-intercept is at (0, -9)
x-intercept: 0 = 3x -9. 9 = 3x. x = 3. The x-intercept is at (3, 0)
5. x intercept: 0 = 5x +10. -10 = 5x. x = -2. The x-intercept is at (-2, 0)
y-intercept: y = 5(0) + 10. y = 10. The y-intercept is at (0, 10)
If you look at finding the y-intercepts in the two problems above, you may see there is a pattern forming. The y-intercept is the number that your adding or subtracting that is located after the x (ex. y = 4x - 2 - the y-intercept would be -2)
9. First, find the x and y-intercepts. The y intercept is -3 You’d graph that at (0, -3). 0 = -1/2x - 3. -1/2x = 3. x = -6 so the x-intercept is at (-6, 0). If you only need to graph 2 points, then you can graph just those two points and draw a line between them.
To graph y=-1/2x + 3, start at the y-intercept and use the slope (-1/2) to find other points. Because your slope is -1/2, you’d go down 1 unit and then to the right 2 units. That would be your next point. If you wanted your line to go further up, go up one unit and then to the left 2 units. That would be your next point.

Anita typed 390 words in 6 minutes. At the rate, how many words can she type in 10 minutes?
Answers
Answer:
She can type 650 words in 10 minutes.
Step-by-step explanation:
390 divided by 6 is 65. Anita types 65 words per min. 65 times 10 is 650. Therefore she types 650 words in 10 mins.
Answer:
650 words
Step-by-step explanation:
So you divide 390 by 6 so that you can figure out how many words she types per minute.
390/6= 65
So she types 65 words per minute,
Then you multiply 65 by 10 because thats how many minutes your trying to figure out.
65*10= 650
You have a summer job that pays time and half over time ( if you work more than 40 hours) after that is 1.5 times you hourly rate of $7.00/ hr.
Answers
Answer:
Step-by-step explanation:
Having a job that pays at $7 per hour is quite nice. And the question says that if he does overtime, he gets 1 and a half times the normal price of $7. This means that, for every overtime he works, he will get paid at
7 * 1.5 = $10.5
The question didn't state what, but if it's anything to go by the wages expected to be paid then I'd say the job isn't worth it if it's overly stressful. I said so because most jobs out there aren't really about the workers, but the money instead.

Explain how we know that the sine of 270 degrees is -1. State one other value of θ such that sinθ=1.
Answers
Solution :
Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.
We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :
(1 cos θ, 1 sin θ).
And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.
Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).
So the value of sin 270° = -1.
One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.
What is the surface area of the cylinder?
226.08 cm²
678.24 cm²
1,356.48 cm²
452.16 cm²
Answers
Answer:
452.16
Step-by-step explanation:
i got it right on test
The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
We have to given that;
Height of cylinder = 6 cm
And, Diameter of cylinder = 12 cm
Hence, We get;
⇒ Radius of cylinder = 12 / 2 = 6 cm
We know that;
The formula for the total surface area of a given cylinder whose radius is r and height is h is,
TSA = 2πr (h + r)
Hence, We get;
TSA = 2πr (h + r)
TSA = 2 × 3.14 × 6 (6 + 6)
TSA = 37.68 × 12
TSA = 452.16 cm²
Thus, The surface area of the cylinder is,
⇒ TSA = 452.16 cm²

The highest elevation in Delaware is 106 feet higher than the highest elevation in Florida. Louisiana's highest elevation is 190 feet higher than Florida's highest elevation. If you climbed from sea level to the highest points in Delaware, Florida, and Louisiana, you would only climb 1331 feet. How high is the highest elevation in each of the three states?
Answers
Answer:
Florida = 345 feets
Delaware = 451 feets
Louisiana = 535 feets
Step-by-step explanation:
Given that:
Let :
Highest elevation in Florida, = x
Highest elevation in Delaware = x + 106
Highest elevation in Louisiana = x + 190
Sum of highest elevation in the 3 states = 1331 feets
Hence,
x + x + 106 + x + 190 = 1331
3x + 296 = 1331
3x = 1331 - 296
3x = 1035 feets
x = 1035 / 3
x = 345 feets
Hence,
Highest elevation in Florida, = x = 345
Highest elevation in Delaware = 345 + 106 = 451
Highest elevation in Louisiana = 345 + 190 = 535
