ASAP Analyze the Error: What is the error in the way the calculation of the slope of the two points is set up and/or solved? Please be specific.
Answers
Answer/Step-by-step explanation:
Given two points on a line, (-4, 10) and (0, 2), the slope of the line is calculated as follows:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-4, 10) = (x_1, y_1) [/tex]
[tex] (0, 2) = (x_2, y_2) [/tex]
Plug in the values
[tex] slope (m) = \frac{2 - 10}{0 - (-4)} [/tex]
[tex] slope (m) = \frac{-8}{4} = -2 [/tex]
Slope = -2
The wrong formula was used. Slope is supposed to be change in y over change in x. Rather the difference of each coordinates was solved and divided by each other, which makes the whole calculation wrong.

As x increases, g(x) increases.
g(x) is greater than –2.50 for x values less than –1.
h(x) is less than –2.50 for x values greater than –2.
The input value for which g(x) = h(x) is between –1 and 0.

Polynomials of degree greater than 2 can have more than one max or min value. The largest possible number of minimum or maximum points is one less than the degree of the polynomial. The following examples illustrate several possibilities.

Answers
Answer: See explanation
Step-by-step explanation:
7.) 2 (x - 1) = 45
2x - 2 = 45
Add 2 to both sides
2x = 47
x = 23.5
8.) 5x - 2 = 2 (4)
5x - 2 = 8
Add 2 to both sides
5x = 10
Divide both sides by 5
x = 2
9.) x = 2 (30)
x = 60
10.) 3x - 6 = 2 (x)
3x - 6 = 2x
Add 6 to both sides
3x = 2x + 6
Subtract 2x from both sides
3x - 2x = 6
x = 6
2x + 1
Substitute x for 6
2 (6) + 1
12 + 1 = 13
2y = 13
Divide both sides by 2
y = 6.5

Susan has 20 pieces of candy in a bag: 6 mint sticks, 11 jelly treats, and 3 fruit tart chews. If she eats one piece every 5 minutes, what is the probability her first two pieces will both be jelly treats?
Answers
Answer:
55%
Step-by-step explanation:
1. You add all the candy together to show that all the candies added together equals 20.
11+6+3=20
2. You divide 11 by 20 to get the decimal
11/20=.55
3. To get the percentage you just have to multiply .55 by 100.
4. The final answer should be 55 %
Graph by finding the intercepts
9x-15y = 45
Answers
Answer:
Look at picture
Step-by-step explanation:
X intercept is when y = 0. so...
9x -15*0 = 45
9x = 45
x = 5. so the coordinate is (5,0)
Y intercept is when x = 0. so...
9*0 - 15y = 45
y = -3. so the coordinate is (0,-3)
then you plot these 2 points and draw a line going across them
If one angle of a triangle is 90°, then the other two add to 90°.
Write the To Prove statement
Answers
If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be.
180°-90°=90°
So the other two angles added together will have to equal 90°.

yesterday 170 guests at a hotel called for room service, and 255 guests did not call for room service. what percentage of the guests did not call for room service yesterday
Answers
Answer:
About 53% of guests did not call for room service
Step-by-step explanation:
Total number of guests is 170+255= 425 guests total
Number of guests who didn’t call room service divided by the total number of guests gives us the percentage of guests who didn’t call room service
255/425 = 0.529412
Multiply by 100 to get a percentage
= 52.9412%
We can round to 53%.

4x-6+3(2-x)=2x-(x-4)
How many solutions are there to this equation?
Answers
Answer:
No solution (0 solutions)
Step-by-step explanation:
Simplify it as shown below:
4x-6+3(2-x)=2x-(x-4)
4x-6+6-3x=2x-x+4. (on the left side the negative 6 and the positive 6 cancel out, and then combine like terms on both sides)
x=x+4
No solution
Answer:
no solutions
Step-by-step explanation:
Given
4x - 6 + 3(2 - x) = 2x - (x - 4) ← distribute and simplify both sides
4x - 6 + 6 - 3x = 2x - x + 4
x = x + 4 ( subtract x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution
Steven bought a new computer at the end of a sale. The price of the computer was $52 on the day he bought it. The next day it had been marked up by 40%. What was the new price after the sale?
Answers
Answer:
$72.80
Step-by-step explanation:
You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.
(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
The new price after the sale of a new computer is, $72.8
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The price of the computer was $52 on the day he bought it.
And, The next day it had been marked up by 40%.
Let the new price after the sale of a new computer = x
So, We can formulate;
⇒ x = $52 + 40% of $52
⇒ x = $52 + 40 × 52/100
⇒ x = $52 + $20.8
⇒ x = $72.8

Patrick invested money into a special savers bank account each year money in the account earns 4% interest after one year, the total amount of money in the account was £291.20 how much did Patrick invest?
Answers
Answer: £280
Step-by-step explanation:
After a year, the total amount that was in the account was £291.20 which according to the question is 4% more than the amount Patrick invested.
Assume the amount invested is x.
x + 0.04x = 291.20
1.04x = 291.20
x = 291.20/1.04
= £280
