What is the equation of the line that passes through the point (−1,−5) and has a slope of −3?
Answer:
[tex]y=-3x-8[/tex]
Step-by-step explanation:
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
1) Plug the slope (m) into the equation
We're given that the slope is -3. Plug -3 into the equation
[tex]y=-3x+b[/tex]
2) Solve for the y-intercept (b)
To solve for b, plug the given point (-1,-5) into the equation as (x,y).
[tex]-5=-3(-1)+b\\-5=3+b[/tex]
Subtract 3 from both sides
[tex]-5-3=3+b-3\\-8=b[/tex]
Therefore, the y-intercept is -8. Plug -8 back into our original equation as b
[tex]y=-3x-8[/tex]

Kimberly collects data on the average temperatures in January in her state over the last 30 years. She then calculates the mean and median for the data set.
Kimberly decides to collect data from two more years and add them to her original data set. The first year, the average temperature is colder than it had been for any of her previous recorded data. The second year, the average temperature is warmer than for any of her previous data.
Which statement describes how adding the two new temperatures to Kimberly's data set could change the statistical measures?
A
The mean and median may both change.
B
The mean and median will both stay the same.
C
The median may change, but the mean will not change.
D
The mean may change, but the median will not change.
Answer:
D.) The mean may change, but the median will not change.
Step-by-step explanation:
By adding two new values to the existing dataset ; this two values are extreme values as described in the dataset.;
As the warmer will be the new minimum and the colder the new maximum .
The median value being the midpoint of the dataset when arranged in order will definitely not be affected by these new additions are at the beginning and end of the data set. Hence, the previous median points will Also be the new median points.
As for the mean, it has to do with calculation the average value, despite the number being at the extreme, the new points may take up any value and hence will affect the new sum and ultimately the obtained average.
Therefore,The mean may change, but the median will not change.

Answer:
A=330
Step-by-step explanation:
im not sure which is the length width height
but if length is 10
width is 3/5
height is 15
A=2(wl+hl+hw)=2·(0.6·10+15·10+15·0.6)=330
then the area would be 330
Decrease £120 by 12.5%
Answer:
£ 105.
Step-by-step explanation:
Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:
100 - 12.5 = 87.5
100 = 120
87.5 = X
87.5 x 120/100 = X
10,500 / 100 = X
105 = X
Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

None of the triangles are right triangles.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
For a triangle to be a right triangle, the Pythagorean theorem must be satisfied.
So,
Applying the Pythagorean theorem.

Bryce tried to solve an equation step by step. \qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}
Answer:
Bryce is wrong in step 1 because he did not distribute 3 over 5/3
Explanation
Given the steps taken by bryce as shown, we are to find where he made an error
[tex]\qquad\begin{aligned} \dfrac83&=3\left(c+\dfrac53\right)\\\\ \\ \dfrac83&=3c+\dfrac53&\green{\text{Step } 1}\\\\ \\ 1&=3c&\blue{\text{Step } 2}\\\\ \\ \dfrac13&=c&\purple{\text{Step } 3}\\\\ \end{aligned}[/tex]
Given the expression;
[tex]\dfrac83&=3\left(c+\dfrac53\right)\\\\ \\[/tex]
Step 1:Expand the bracket using the distributive law;
8/3 = 3c + 3(5/3)
Simplify
8/3 = 3c + 15/3
Step 2: Subtract 15/3 from both sides
8/3 - 15/3 = 3c+15/3-15/3
(8-15)/3 = 3c
-7/3 = 3c
Step 3: Multiply both sides by 1/3
-7/3 * 1/3 = 3c * 1/3
-7/9 = c
Swap
c = -7/9
From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect

Answer:
m∠ECD = 145°
m∠FCA = 35°
m∠PDF = 70°
Step-by-step explanation:
For ∠ECD:
- You can find this angle using supplementary angles. ∠ECD and ∠ECB are supplementary, meaning they add to 180°. Since the measure of ∠ECB is provided, you can subtract that from 180° to get m∠ECD:
180 - 35 = 145°, so m∠ECD = 145°
For ∠FCA:
- You can solve this problem using the Vertical Angles theorem. It states that vertical angles are congruent. ∠FCA's vertical angle pair is ∠ECB, which is 35°, so you can deduce that m∠FCA = 35°
For ∠PDF:
- You can find the measure of this angle by using supplementary angles like for ∠ECD. ∠PDC is supplementary to ∠PDF, and it's value is given. so you can find PDF by subtracting the value of ∠PDC from 180:
180 - 110 = 70°; m∠PDF = 70°
Which side lengths do not make a triangle ?
10, 15, 23
1, 2, 4
5, 6, 7
6, 8, 9
Answer:
1,2,4
Step-by-step explanation:
Okay so basically in a triangle, the sum of any two sides should be greater than the third remaining side. So if we had a triangle with sides A, B, and C, A+B>c, A+C>B, and B+C>A. If you look at 1,2, and 4, 1=2=3 which is less than 4. That is why that is not a triangle.
Probabilities. Please help
In throwing a dice, there are 6 possible outcomes, namely 1, 2, 3, 4, 5 and 6.
P=(no. of favourable outcomes)/(no. of possible outcomes)
When we multiply the probability of an event with no. of trials, the we get the expected frequency of that event.
1) P(getting 1)=1/6
expected frequency of getting 1
=P(getting)1)×no. of trials
=1/6×600=100
But it is given that one is scored 200 times, so it makes a large difference from expected frequency, which is 100.
Therefore, the dice is not fair.
2) P(getting a tail)=0.3
estimate for the number of times the coin will land on a tail
=expected frequency of getting a tail
=P(getting a tail)×no. of trials
=0.3×150=45
3)P(getting a six)=2/3
expected frequency of getting a six
=P(getting a six)×no. of trials
=2/3×300=200
4)P(getting a three)=0.5
expected frequency of getting a three
=P(getting a three)×350
=0.5×350=175
Three pizzas and four sandwiches cost $34. Three pizzas and seven sandwiches cost $41.50. How much does a pizza,
p, and a sandwich, s, cost?
Answer: p= $8 s= $2.50
Step-by-step explanation:
3p + 4s = 34 and 3p + 7s= 41.50
Since the number of pizzas DIDNT change between these two equations, we can use the total of the second equation to help us find the price of one sandwich.
41.50 - 34 = $7.5 for 3 sandwiches (7s-4s)
So how much is one sandwich? 7.50/3 = $2.50 for each sandwich
now that we know s, it’ll be much easier finding p. We can use one equation to find p.
3p + 4(2.5) = 34 (Solve algebraically)
3p + 10 = 34
- 10 | -10
3p = 24
3p/3 = 24/3
p = $8. Now you can check by substituting the variables!
