Answer:
Step-by-step explanation:
The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
Answer:
y = 42 - 6 x

Step-by-step explanation:
Lines m and n are parallel, solve for the following values of x. Tell which theorem you used(name the angle pair)
Answer:
x = 90 (Alternate exterior angles)
Step-by-step explanation:
Given that,
Lines m and n are parallel.
We need to find the value of x.
Here, (180-x) will be equal to x as the alternate exterior angles are equal. So,
(180-x) = x
180 = 2x
x = 90
So, the value of x is equal to 90°.
Find the value of x in the figure shown.
Answer:
17Step-by-step explanation:
3x +39 =90
3x =90-39
3x=51
make it in fraction
3x over 3 equals to 51 over 3
simplify
= 51
Answer:
x = 17
Step-by-step explanation:
a straight line equals 180º so each side is 90º.
90 - 39 = 51
3 x __ = 51
3 x 17 = 51
so..x = 17
Which statement is true about a trend line?
A regression line and a trend line our opposite terms.
A regression line and trend wine are equivalent terms.

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).
Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.

Identify the number that does not belong with the other three. Explain your reasoning.
Answer:
To identify which integer does not belong with the rest, we must first evaluate each.
Step-by-step explanation:
[25.6...] is already evaluated. Therefore, let's move on to Integer b: [tex]\sqrt{x}[/tex], where is x is 48.48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3√48 = [tex]\sqrt{2}[/tex] * 2 * 2 * 2 * 3We have 1 perfect sqaure: [tex]\sqrt{2}[/tex] * 2When we multiply, we receive 2.Therefore, 2 * [tex]\sqrt{2 * 3}[/tex]When -51/2 is relatively prime, we receive -25 1/2Finally, the last integer is already simplified.Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.

Find the area of the shaded polygon.
Answer:
8 square unitsStep-by-step explanation:
Split the polygon into 3 triangles as pictured below
They have base and height:
4 and 3, 1 and 1, 3 and 1Find the area of 3 triangles and add up:
A = 1/2bhA = 1/2*4*3 + 1/2*1*1 + 1/2*1*3 = 6 + 1/2 + 3/2 = 8 square unitsAnswer:
8
Step-by-step explanation:
The lengths of the sides of triangle XYZ are written in terms of the variable m, where m ≥ 6. Triangle X Y Z is shown. The length of side X Y is m + 8, the length of side Y Z is 2 m + 3, the length of side Z X is m minus 3. Which is correct regarding the angles of the triangle? mAngleX < mAngleZ < mAngleY mAngleY < mAngleZ < mAngleX mAngleY < mAngleX < mAngleZ mAngleZ < mAngleY < mAngleX
Answer:
mAngleY < mAngleZ < mAngleX
Step-by-step explanation:
Since m ≥ 6
Let's assume m = 7
XY = m + 8 = 7 + 8 = 15
YZ = 2 m + 3 = 2(7) + 3 = 17
ZX = m - 3 = 7 - 3 = 4
When solved, the angles of the triangle are given below;
∠X = 113.58
∠Y = 12.45
∠Z = 53.97
Arranging in order;
∠Y < ∠Z < ∠X
The correct option is;
mAngleY < mAngleZ < mAngleX

What is the measure of the missing angle?
Answer:
79 degrees
Step-by-step explanation:
You add the two angles and get 79. Then you subtract it from 180 because it is a straight angle. 180-101=79
Answer:
79
Step-by-step explanation:
28+73+x=180
a straight line is 180. That's how I got what it is equal to.
28+73= 101
101+x=180
subtract
180-101= 79

Answer:
Step-by-step explain to solve for the maximum area, the first derivative should be solved and equate it to zero, then solve for x.
A = 37x - x^2
dA / dx = 37 - 2x
equate dA / dx = 0
0 = 37 - 2x
2x = 37
x = 37 / 2
x = 18.5 ft
so the maximum area is
A = 37x - x^2
A = 37( 18.5) - 18.5^2
A = 342.25 sq ft
so the answer is letter B
Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26 By what percentage has Rebecca's car insurance been reduced?
Answer:
Step-by-step explanation:
Rebecca's car insurance been reduced by 18%
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.
Percentage decrease = (Final value - initial value) / initial value × 100
Final value = £1675.26
Initial value = £2043
Percentage decrease = (2043 - 1675.26) / 2043 × 100
= 367.74 / 2043 × 100
= 0.18 × 100
= 18 %
Hence, Rebecca's car insurance been reduced by 18%

The distribution of tips given by customers who buy one cup of coffee is bimodal with a mean of $0.29 and a standard deviation of $0.1164. If a random sample of 50 tips from customers who buy one cup of coffee is selected, is it appropriate to calculate the probability of a sample mean being more than $0.32 using an approximately Normal model?
Yes, the population of all people who buy one cup of coffee is extremely large, so the shape of the sampling distribution of x is not a concern, and P(x> 32) = 0.0372.
Yes, since the sample size 50 is large enough, the sampling distribution for x would be approximately Normal, and P(x>32) = 0.0372.
Yes, since the sample size 50 is large enough, the sampling distribution for x would be approximately Normal, and P(x> 32) = 0.3983.
No, it is not appropriate to estimate the probability using an approximately Normal model because the population is not Normal, and the sample size is not reasonably large.
Answer:
Yes, the population of all people who buy one cup of coffee is extremely large, so the shape of the sampling distribution of x is not a concern, and P(x> 32) = 0.0372.
