Find the equation of the line that passes through the points A (2, 3) and B (5, -7)
Answer:
10x+3y=29
Step-by-step explanation:
Given points:(x1,y1)=(2,3)
(x2,y2)=(5,-7)
We know, the equation of line passing through two points is given by,
y-y1={(y2-y1)/(x2-x1)}*(x-x1)
Hence,y-3={(-7-3)/(5-2)}*(x-2)
or,y-3=(-10/3)*(x-2)
or,3y-9= -10x+20
or,3y+10x=20+9
or,10x+3y=29 is the required equation.

PLEASE HELP!
Answer:
Step-by-step explanation:
The red sections are sectors of the circle. We need that area. We'll find one then multiply it by 2, since they're both the same.
[tex]A_s=\frac{60}{360}\pi (4)^2\\A_s=\frac{1}{6}\pi (16)\\A_s=8.377[/tex]and now we multiply it by 2 to get the red area:
[tex]A_s=16.754[/tex]
And now the area of the circle:
[tex]A_c=\pi (4)^2\\A_c=16\pi\\A_c=50.265[/tex] and now divide to get the percentage:
[tex]\frac{16.754}{50.265}*100=[/tex] 33.3%

Write an exponential function in the form y = ab" that goes through points (0,7)
and (9,3584).
Answer:
Step-by-step explanation:
I'm going to assume you meant y = ab^x. If this is not correct, leave a comment.
x = 0
y = 7
7 = a * b^0
anything to the zero power is 1
y = a*b^0
y = a*1
7 = a
So far what you have is
y = 7 * b^x
Now let
x = 9
y = 3584
3584 = 7 * b^9 Divide by 7
3584/7 = b^9
512 = b^9
If you knew how to use logs, that would be the surest way to do this question. However I'm going to make an assumption again and assume that you have not taken those yet.
So the easiest way is to find out what raised to the 9th power will equal 512
Could b = 5?
5^9 = 1 million 9 hundred thousand something. 5 is far too big. Make sure you understand why. 1 million is far greater than 512
So let's try b = 3
3^9 = 19 thousand which is still far too big. 19 thousand something is far larger than 512.
We have just one more number that we can try.
2^9 = 512 and we have it

The price of a bracelet is $1.29. If the tax rate is 5%, find the total cost of the bracelet
Answer:
Cost of bracelet = $1 and 35 cents
Step-by-step explanation:
Price before tax = $ 1.29
Tax Price = 5% of 1.29
[tex]=\frac{5}{100} \times 1.29\\\\= 6.45 \times \frac{1}{100} \\\\= 0.0645[/tex]
Therefore price after tax = 1.29 + 0.06245 = 1.3545
Ans : cost of bracelet = $1 and 35 cents

Write 8 as a percentage of 32
Plssss helppp
Answer:
25% of 32 is 8
Step-by-step explanation:
[tex]\frac{x}{100} * 32 = 8\\\\x = 25%[/tex]
Therefore, 25% of 32 is 8.
8 is 25% of 32.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We know that, 8/32=1/4
in percentage form, 8 of 32= 1/4×100
=25%
Hence, 8 if 25% of 32.

Write an equation for the line that is parallel to the given line and that passes through the given point. y = 1/2x - 8; (-6, -17).
Answer:
y = 1/2x - 14
Step-by-step explanation:
Parallel lines have the same gradient
So,
gradient for second line = gradient of the first line = 1/2
Also,
the line passes through (-6,-17)
So, we can find the y-intercept by substitution
y = mx + c
-17 = (1/2 * -6) + c
-17 = -3 + c
c = -14
So,
the equation is y = 1/2x - 14

Mary Lou is twice George’s age and Kate is one year younger than George. The sum total of their ages is 27. How old is each person?
Answer:
Mary Lou is 14
George is 7
Kate is 6
Step-by-step explanation:
let G = George's age
let 2G = Mary Lou's age
let G-1 = Kate's age
G + 2G + G-1 = 27
4G = 28
G = 7
2G = 14
G-1 = 6
