What is the solution of -17 = -2y + 13 – 8y?
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3

Determine the slope, the y-intercept and the
x-intercept of the line 4x - 3y - 42 = 0.
Answer: 3/4
Step-by-step explanation:
First we need to get the formula into slop form (Y = Mx + B) by moving Y to the other side. This can be done by adding 3y to both sides.
4x - 42 = 3y
or
3y = 4x - 42
Now that we have the formula, we need to divide everything by 3 in order to get 1y.
y = 3/4x - 14
In this formula, M is the slope, meaning your final answer is
3/4
Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 miles south. What distance, to the nearest tenth of a mile, would he travel if he took a direct flight from Portland to Denver?
1153.5 miles
1575 miles
425 miles
818.2 miles
Answer:
1153.5 miles (first answer choice)
Step-by-step explanation:
'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise'). Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:
d = √(1000² + 575²) = 1153.5 miles (first answer choice)

Mrs. C loans Mr. R $50 000 to start his magic shop. She charges him 20% interest compounded anually. how much will he own her in FIVE years? Show your work including the formula for calculating compound interest.
Answer:
2,000
Step-by-step explanation:
Answer: it should be 100,000
Step-by-step explanation:
If I am doing this right than 20% of 50,000 is 10,000. That will be 50,000. So 50,000+50,000=100,000.

The slope is -2, and the y-intercept is 6.
O The slope is -2, and the y-intercept is 12.
The slope is 2, and the y-intercept is 6.
The slope is 2. and the y-intercept is 12.
Answer:
slope is -2 and the y-intercept is 12
Step-by-step explanation:
a key thing to remember: x is always equal to 0 when finding the y-intercept.
so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12.
to find the slope use the equation: slope= change in y/change in x
you can use any two points to find this.
lets take the points of the x-intercept (6,0) and the y-intercept (0,12)
12-0/0-6
12/-6
-2 = slope

What is the midnumber between 1 and 7 ?
( 1 + 7 ) ÷ 2 =
8 ÷ 2 = 4
That was the direction now tell me what is the midpoint of point A and point B ?
midpoint of AB = ( A + B ) ÷ 2
m o AB = ( ( 14 , 15 ) + ( - 2 , 9 ) ) ÷ 2
m o AB = ( ( 14 - 2 , 15 + 9 ) ) ÷ 2
m o AB = ( ( 12 , 24 ) ) ÷ 2
m o AB = ( 12 ÷ 2 , 24 ÷ 2 )
m o AB = ( 6 , 12 )

Special Right Triangles (Radical Answers)
Answer:
x = [tex]5\sqrt{2}[/tex]
Step-by-step explanation:
We know that;
The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.
Therefore we can say;
5² + 5² = x²
25 + 25 = x²
50 = x²
[tex]\sqrt{50}[/tex] = x
We can simplify this further;
[tex]\sqrt{25} * \sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]
[tex]5\sqrt{2}[/tex] = [tex]\sqrt{50}[/tex]

What is the coefficient in the following expression? 5a2-7
Answer:
coefficient = 5
Step-by-step explanation:
Find the volume of this cylinder.
Round to the nearest tenth.
17 ft
8ft
[ ? ) ft3
Enter
Answer:
The answer is 3418.1 ft rounded to the nearest tenth.
Step-by-step explanation:
The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.
The area of the circular base can be calculated as
[tex]\pi \times {r}^{2} [/tex]
where r is the radius of the circular base, which is 8 ft.
The area of the circular base is
[tex]\pi \times {8}^{2} = 64\pi[/tex]
We also know the height of the cylinder is 17 ft.
Hence, the volume of the cylinder is
[tex]64\pi \times 17 = 1088\pi = 3418.0528...[/tex]
This will be rounded up to 3418.1 with the nearest tenth

Jim Part 2 Homework Algebra more June 3rd
Answers:
6. A) 120 plus or minus 17. A) (0, 22.7)8. B) When there are 0 people, the max noise is 22.7 dB9. D) 8910. B) The player had 318 at bats and 80 hits.========================================================
Explanations:
6. Plug in x = 65 and evaluate. You should get y = 120.2 which is fairly close to 120, give or take a decibel or so. 7. The y intercept is the value of b in y = mx+b. In this case, b = 22.7 and the location of the y intercept is (0, b) = (0, 22.7)8. Plug in x = 0 and you should get y = 22.7, which is the y intercept mentioned earlier. It means that if x = 0 people show up, ie the stadium is empty, then the noise level is 22.7 dB. This is probably unrealistic as there's no people around to make noises, unless there are machinery or similar making sounds. 9. Form the proportion 147/526 = x/317. Solve for x to get roughly x = 88.591, which rounds to 89. If we have 89 in this cell, then the row relative frequencies will fairly be the same (ie each row is pretty much identical after we compute the row relative frequencies) and that leads to a likely case we don't have association. 10. The point (x,y) = (318, 80) means x = 318 and y = 80 pair up together. The variable x is the number of at bats, and y is the number of hits.In this set of data, would the mean or median be affected more with a data point of 20? Explain.
Here is the data set:
{1, 2, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7}
Answer:
5 is the median
Step-by-step explanation:
The "median" is the "middle" of the set of numbers. Considering there are 13 total numbers, making it un-even, there can be an equal amount of numbers taken off of each side with a middle number remaining. That middle number will be your median..
