Write the equation of the line that passes through (-3, -20) and (1, 4).
Answer:
y=6x-2
Step-by-step explanation:
first step: find the slope
equation to find slope: (y2-y1)/(x2-x1)
let x1, y1 be (-3, -20)
let x2, y2 be (1, 4)
(4 - (-20))/(1 - (-3)) = 24/4 = 6
plug in 6 and x,y to find b
4=(6)(1) + b
subtract 6 on both sides = -2=b
y=6x-2

joe measured a brick using a ruler with centimeters and got 9 cm. he then measured the same brick using a ruler with millimeters and got 90 mm. are these measurements equivalent?
Answer:
yes
Step-by-step explanation:
1 cm=10mm. if 1cm=10mm what about 9cm
Yes, they are equivalent when he got 9 cm and we got 90 mm while measuring it.
Calculation of the measurement:Since he used the ruler with centimeters and got 9 cm
And, if he used a ruler with millimeters and got 90 mm
So the measurement should be equal
As we know that 1 cm=10mm
So based on this, they are equivalent

The product of two consecutive positive integers is 1,332. Explain how you can write and solve a quadratic equation to find the value of the larger integer.
x - the larger integer (x>0)
x-1 - the smaller integer (the difference between two consecutive integers is always 1)
The product of two consecutive positive integers is 1,332
so:
x•(x -1 ) = 1332
x² - x = 1332
x² - x - 1332 = 0 ⇒ a = 1, b = -1, c = -1332
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-1)\pm\sqrt{1^2-4\cdot1\cdot(-1332)}}{2\cdot1}=\dfrac{1\pm\sqrt{1+5328}}{2}\\\\\\x_1=\dfrac{1+\sqrt{5329}}{2}=\dfrac{1+73}{2}=37\\\\x_2=\dfrac{1-\sqrt{5329}}{2}\ \not>\ 0[/tex]
x = 37
Answer:
The numbers can be written as x and x + 1. Set the product of the numbers equal to 1,332 to get x(x + 1) = 1,332. You can solve the quadratic equation by using the quadratic formula, completing the square, or factoring. When you solve the quadratic equation, you find that x = –37 and 36. Since the question asked for positive integers, the only viable solution is x = 36. To solve for the larger integer, you add 1 to 36 to get an answer of 37.

Four swimmers competed in the 100-meter freestyle.
Their times were 68.92 seconds, 72.3 seconds, 73.2
seconds, and 69.15 seconds.
If the lowest number represents the person who came
in first, what was the time of the person who came in
third place?
O 68.92 seconds
O 72.3 seconds
O 73.2 seconds
O 69.15 seconds
Answer: 72.3
Step-by-step explanation: least to greatest would be 68.92, 69.15, 72.3, 73.2
So with that information and knowing that the lowest number represents the person who came in first, then we know 72.3 is the person who came in third place.

(a) The perimeter of a rectangular field is 372 m.
If the width of the field is 87 m, what is its length?
Answer:
98 m
Step-by-step explanation:
Answer:
The length of the field is 99 m.
Step-by-step explanation:
First, multiply 87 by 2 to get 174. Then, subtract 174 (total of the two width sides) from 372 (total perimiter) to get 198. Lastly, divide 198 by 2, because 198 is the total of the 2 length sides, and you will get 99 m per length side.

#17, #18, #19
Answer:
they all equal 105°
Step-by-step explanation:
Answer:
∠ 2 = ∠ 5 = ∠ 7 = 105°
Step-by-step explanation:
∠ 2 and ∠ 3 are same- side interior angles and are supplementary, thus
∠ 2 = 180° - ∠ 3 = 180° - 75° = 105°
∠ 5 and ∠ 2 are vertical angles and congruent, thus
∠ 5 = 105°
∠ 2 and ∠ 7 are alternate angles and congruent, thus
∠ 7 = 105°

Answer:
Price(P) = $200
Maximum charge = 200
Step-by-step explanation:
Given:
Sales = 600 - 3p
Number of customer = 0
Find:
Price(P)
So,
600 - 3p = 0
3p = 600
Price(P) = $200
Revenue = [600 - 3p]p
600p - 3p²
Maximum charge = 200
