Write the equation of the line that passes through the points (5,0) and (-6, -1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
The equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]
Step-by-step explanation:
We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).
The general equation of point slope form is: [tex]\mathbf{y-y_1=m(x-x_1)}[/tex]
where m is the slope of line.
We need to know Slope m
Finding Slope m
Finding Slope m using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1[/tex]
Putting values and finding slope
[tex]Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}[/tex]
So , slope m is: [tex]\mathbf{m=\frac{1}{11}}[/tex]
Using point (5,0) and slope m =1/22 the equation of point-slope form is:
[tex]y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}[/tex]
So, the equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

i added a picture : Determine which of the lines, if any, are parallel or perpendicular. Explain.
write an equation of the line that passes through the given point and is perpendicular to the given line.
Answer:
1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9
Step-by-step explanation:
To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
9x10^7 is how many times as large as 3x10^-2
Answer:
3000000000 or 3x10^9 times bigger
Step-by-step explanation:
Power in mathematics is defined as the number you get when you get when you raise a number to an exponent
[tex]9 * 10^{7}[/tex] is 3000000000 or [tex]3 * 10^{9}[/tex] times as large as [tex]3 * 10^{-2}[/tex]
To calculate how many times [tex]9 * 10^{7}[/tex] is larger than [tex]3 * 10^{-2}[/tex] we would be dividing [tex]9 * 10^{7}[/tex] by [tex]3 * 10^{-2}[/tex] .This is expressed mathematically as:
[tex]\frac{9*10^{7} }{3*10^{-2}}[/tex]
= 3,000,000,000
or we express it as a power : [tex]3 * 10^{9}[/tex]
Therefore, is 3000000000 or times as large as

Choose the division equation that represents the fraction shown 1/7
Answer:
1÷7 is the answer
Suppose that the world's current oil reserves is R = 1820 billion barrels. If, on average, the total reserves
is decreasing by 18 billion barrels of oil each year, answer the following:
A.) Give a linear equation for the total remaining oil reserves, R, in billions of barrels, in terms of t, the
number of years since now. (Be sure to use the correct variable and Preview before you submit.)
R
B.) 14 years from now, the total oil reserves will be
billions of barrels.
C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted (all
used up) approximately
years from now.
(Round your answer to two decimal places.)
Answer:
A. R = -18t + 1,820
B. 1,568 billions of barrels
C. approximately 101.11 years
Step-by-step explanation:
To make our equation, we'll use the form R = mt + b. M represents how many billion barrels of oil are being lost each year, which we know is 18 billion. So -18 will be our m. B is how many total barrels of oil there are, which is 1,820. So 1,820 will be our b. Now the equation looks like this:
R = -18t + 1,820
We can use this equation to answer Part B.
Replace the t with 14:
R = -18(14) + 1,820
Now solve for R:
R = -18(14) + 1,820
R = -252 + 1,820
R = 1,568
14 years from now, there will be 1,568 billions of barrels left.
To solve part C, we need to find how many years it will take for all of the oil to be used up. After it's all used up, the total amount of oil will be 0, so we can replace R with 0 and then solve for t:
0 = -18t + 1,820
Subtract 1,820 from both sides to isolate -18t:
0 - 1,820 = -18t + 1,820 - 1,820
-1,820 = -18t
Divide both sides by -18 to isolate the t:
-1,820/-18 = -18t/-18
101.11 = t
After approximately 101.11 years, all of the oil will be used up.

Ben and his three friends were ordering pizza. They could spend at most $26. If a large
cheese pizza costs $22 and toppings are $0.65 each, how many toppings could they
get?
Answer:
6 toppings
Step-by-step explanation:
The t in this equation represents the amount of toppings.
22 + 0.65t = 26
-22 -22
0.65t = 4
0.65t/0.65 = 4/0.65
t = 6
They could get 6 toppings and the total would be $25.90.

Answer:
144
Step-by-step explanation:
Since the triangle is equilateral all the sides are equivalent, meaning you can make any 2 sides equal to eachother
4x + 32 = 12x
32 = 8x
x=4
Replace the x of one of the sides
12(4) = 48
and since we are finding the perimeter multiply 48 by 3 since there are 3 sides
48(3)

Answer:
<1 =100 (check explanation for why)
<2 = 80 (check explanation for why)
<3 = 100 (check explanation for why)
Step-by-step explanation:
You can get <1 from the given angle being a linear pair to <1, so:
180= 80+ <1
100= <1
You can get <2 from being a linear pair to <1, so:
180 = 100 + <2
80 = <2
You can get <3 from being a linear pair to <2
180 = 80 + <3
100= <3
Answer:
m<1= corresponding
m<2=vertical angle
m<3=consecutive interior angle

10. x² + 169 = 0
Algebra 2
Answer:
13i, -13i
Step-by-step explanation:
x^2=-169
169=(13)^2
x^2=-(13)^2
the square root of -1 is i ( imaginary number )
(-13)^2=(13)^2 so x is 13i and -13i
Answer:
13i
Step-by-step explanation:
So I would solve for x
This is zero term factoring
This is a square root factor and 169's square root is 13.
However we need to factor -169
This is where imaginary numbers come in. i= Square root of -1
13i would be the answer
If a piggy bank consists of quarters and dimes.
There are 4 more dimes than quarters and the total
value of all the coins is $4.60. How many quarters
and dimes are there in the bank?
Answer:
There are 12 quarters and 16 dimes
Step-by-step explanation:
Firstly, we need to know that a quarter is worth $0.25 while a dime is worth $0.10
There are 4 more dimes than quarters;
So if there are x quarters, there are x + 4 dimes
From the question we can get;
0.25(x) + 0.1(x + 4) = 4.6
0.25x + 0.1x + 0.4 = 4.6
0.35x = 4.6-0.4
0.35x = 4.2
x = 4.2/0.35
x = 12
X + 4 = 12 + 4 = 16
