Answer:
y = 5/2x + 5
y = -1/2x + 11
Step-by-step explanation:
5x -2y = -10
-2y = - 5x -10
y = 5/2x + 5
3x + 6y = 66
6y = -3x + 66
y = -1/2x + 11

Write an equation in point-slope form of the line that passes through the given points. (-2,-5), (4,-1)
Answer:
Step-by-step explanation:
(-1 + 5)/(4 + 2) = 4/6= 2/3
y + 5 = 2/3(x + 2)
y + 5 = 2/3x + 4/3
y + 15/3 = 2/3x + 4/3
y = 2/3x - 11/3
the two lines below are parallel if the slope of the red line is 5 what is the slope of the green line
Answer:
5
Step-by-step explanation:
Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.

“Solve for x, given that
Answer:
x = 20
Step-by-step explanation:
If angle PQS is = 70° then
x + 10 + 4x - 40 = 70 add like terms
5x - 30 = 70 add 30 to both sides
5x = 100 divide both sides by 5
x = 20

In the similar triangles below, solve for the value of X.
9514 1404 393
Answer:
x = 8
Step-by-step explanation:
Corresponding segments are proportional.
(3x +1)/10 = (7x -1)/22
11(3x +1) = 5(7x -1) . . . . . . multiply by 110
33x + 11 = 35x -5 . . . . . . eliminate parentheses
16 = 2x . . . . . . . . . . . add 5-33x to both sides
8 = x . . . . . . . . . . divide by 2
Answer:
Solution :-[tex] \sf \bull \large \: \dfrac{3x + 1}{10} = \dfrac{7x - 1}{22} [/tex]

Is 0.709 better than 0.81 or is it twisted around?
Answer:
twisted.................
Anyone know how to solve this?
Answer:
b = 22
Step-by-step explanation:
Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle. We want to find the value of b. We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:
sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22

Divide 150 by 200:
150/200 = 0.75
Multiply by 100:
0.75 x 100 = 75%
The answer is 75%

18.1
17.3
15.9
16.4
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
[tex]a^{2} +b^{2}= c^{2}[/tex]
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
[tex]10^2+b^{2} =20^{2}[/tex]
Then, use the squares in the equation:
[tex]100+b^{2} =400[/tex]
Then, subtract 100 from both sides to isolate b:
[tex]b^{2} =300[/tex]
Finally, square root both sides to get your answer:
[tex]b=17.3205080757[/tex]
Then round to the nearest tenth which gives you 17.3.

A bag of a certain type of sand weighs 42 pounds and has a volume of 0.5 cubic feet. A sandbox has a volume of 16 cubic feet. Approximately how many pounds of sand will it take to fill the sandbox?
Answer:
1344
Step-by-step explanation:
2 bags of sand = 1 cu ft
2 bags of sand = 84 lbs
Sandbox holds 16 cu ft
16 cu ft * 84 lbs per cu ft = 1344 lbs
What is the solution set for StartAbsoluteValue 4 minus StartFraction x over 2 EndFraction EndAbsoluteValue = 8?
A.x = negative 24 and x = negative 8
B.x = negative 24 and x = 24
C.x = negative 8 and x = 8
D.x = negative 8 and x = 24
The solution to the set is .x = negative 8 and x = 24.
What is Absolute value?The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.
Given:
|4 - x/2| = 8
So, there are two possibilities
4- x/2 = 8 or 4 - x/2 = -8
-x/2 = 8-4 or -x/2 = -8-4
-x/2 = 4 or -x/2 = -12
x= -8 or x= 24
Hence, the solution to the set is .x = negative 8 and x = 24
