Answer: y = 2x + 1
Step-by-step explanation:
Rewrite the equation in standard form:
x+2y=5
2y = -x + 5
y = -(1/2)x + (5/2)
A line perpendicular to this would have a slope that is the negative inverse of the reference line slope, -(1/2), here. The new slope would be 2. The y-intercept, (5/2), will change, so we'll just use b for the new y-intercept, and calculate it later:
y = 2x +b
We know that point (3,7) lies on the new line (it is a solution to the equation), so we can use this point to find the new y-intercept, b.
7 = 2*3 + b
b = 1
The perpendicular line is y = 2x + 1, and goes through point (3,7)

22) B. As the temperature decreases, hot chocolate sales increase.
What's the answer to this?
Answer:
1.5
Step-by-step explanation:
-1.5 + 1.5 will get you to 0
-1.5 + (-1.5) will get you -3. The other options are out of the question
Find the equation parallel to y = -x - 5 and passing through (-3, -3)
Answer:
y = -x - 6
Step-by-step explanation:
If it's parallel, then it means that the slope will remain the same. The slope is
-1.
To find the y-intercept, you need to plug the coordinates into the equation,
y = -1x + b
-3 = -1(-3) + b
-3 = 3 +b
-6 = b
The equation is y = -x - 6
Which of the following is closest to the circumference, in inches, of a circle that has a diameter of 12 inches?
Answer:
37.68 inches
Step-by-step explanation:
The formula for the circumference of a circle is 2πr.
The radius is 6, and 6⋅2 = 12 (diameter).
3.14 = pi.
12 ⋅ 3.14 = 37.68
Whichever answer is closest to 37.68 is your answer!

1/8 + 9/40 as a fraction in simplest form
Answer:
7/20
Step-by-step explanation:
9/40, 9 divided by 40 is 0.225. 1/8, 1 divided by 8 is 0.125. Add 0.225 and 0.125 you get 0.35. 35% (0.35) of 100 to a fraction is 7/20. 7 divided by 2 is 3.5 or 0.35, 20 divided by 2 is 10 or 1. So yeah. Hope This Helps :)

What is the likelihood that a point chosen inside the square will also be inside the circle ?It Chose one : A. is impossible ,B. it is unlikely, C it is likely D. it is certain
Answer:
C. It is likely
Step-by-step explanation:
Given
See attachment for diagram
For the square.
Let
[tex]Length = L[/tex]
So, the area is:
[tex]Area = Length^2[/tex]
[tex]A_1=L^2[/tex]
The side length of the square equals the diameter of the circle.
So:
[tex]diameter (d) = L[/tex]
The radius is:
[tex]r = \frac{1}{2}d[/tex]
[tex]r = \frac{1}{2}L[/tex]
The area is:
[tex]Area = \pi r^2[/tex]
[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]
[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]
[tex]A_2 = \frac{22}{28} L^2[/tex]
The likelihood that a point will be common to the square and the circle is:
[tex]Pr = \frac{A_2}{A_1}[/tex]
[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]
[tex]Pr = \frac{22}{28}[/tex]
[tex]Pr = 78.57\%[/tex]
The above probability is greater than 50% but less than 100%.
Hence, it is likely
Answer:
C. Likely
Step-by-step explanation:
all the points are in the circle so it's likely to choose a point inside the circle

solve for t
-18 = -3t
t = (_)
Answer:
3×6=18 t= (6)
I hope this helps by using division
Answer:
t = 6
Step-by-step explanation:
you want (t) by itself so you would divide both sides by -3. A negative divided by a negative is a positive. same goes for multiplying two negative numbers. The answer would be positive
if the line M is perpendicular to the line end, and the slope of line M is -3 / 2, what is the slope of line and? Write the slope in simplest form
(easy question, easy points)
Answer:
2/3
Step-by-step explanation:
All you do is find the reciprocal,
you take the equation, flip, then change the sign of the numerator. so,
In this it's already done, the sign on top is already changed and so is the equation fliped so we do the opposite,
which would give you 2/3 because the perpendicular line of 2/3 is -3/2 which makes them perpendicular to each other and there is your answer.

find the missing side lengths of the triangle 20 units 21 units
Answer:
29
Step-by-step explanation:
In a triangle, a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
Given this formula, we knoe c^2 is the product of 21^2 + 20^2.
This gives you 841. Now you just find the square root of 841 which is 29.
Hope this helps :)

i neex help on a equation
Answer:
-24a^10
Step-by-step explanation:
Given the equation −4a^5⋅6a^5
This can also be written as
−4a5⋅6a^5
= (-4*6)(a^5*a^5)
= -24(a^{5+5})
= -24a^10
Hence the required expression is -24a^10

The teachers in each class compared their results side by side and determined that class 1 had more variability than Class 2. Which of the following statements BEST describes the conclusion of the teachers?
A. It is not true because the median for each class is the same
B. It is not true because the maximum is the same for each class
C. It is true because the range of Class 1 is greater than the range of Class 2
D. It is true because the minimum for Class 1 is less than the minimum of Class 2
Answer:
c.
Step-by-step explanation:
since the range is bigger, it gives more variability when it comes to data plots

i need help with the last two. I forgot the formula and wondering if you will help me find which one is and isnt a triangle
Answer:
3. D) 26, 7, 31
4. B) 6, 34, 27
Step-by-step explanation:
Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.
#3:
2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.
12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.
14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.
7 + 26 is 33, which is greater than 31. So D would form a triangle.
D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.
#4:
17 + 18 is 35, which is greater than 19. So A would form a triangle.
11 + 22 is 33, which is greater than 25. So C would also form a triangle.
5 + 18 is 23, which is greater than 20. So D would form a triangle.
6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.
B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.
