Answer:
f(-7) = -6
f(10) = 9
Step-by-step explanation:
Because -7 is less than 0 you can use the top equation -7 + 1 to get 6
Because 10 is greater than 0 you can use the bottom equation 10 - 1 to get 9

Determine whether the graph shows a positive correlation, a negative correlation, or no correlation. If there is
a positive or negative correlation, describe its meaning in the situation.
Answer:
The answer is A
Step-by-step explanation:
A city has a vacant lot in the shape of an isosceles trapezoid and the city workers are installing a fence around the lot. What length of fencing is required? Round the answer to the nearest meter. А 25 m B x 25 m 45° The length of fencing required is meters.
Answer:
Length of the fence required = 135 m
Step-by-step explanation:
Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid
Perimeter of ABCD = AB + BC + CD + AD
Since, AB = BC = EF = ED = 25 m
From the given right triangle BEC,
m∠EBC = m∠ECB = 45°
ΔBEC will be an isosceles triangle.
So, BE = EC
By Pythagoras theorem,
BC² = BE² + EC²
25² = 2(EC)²
EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m
And DC = (DF + EF + EC)
= EC + EF + EC [Since, DF = EC]
= 2EC + EF
= 35.4 + 25
= 60.4 m
Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25
= 135.4 m
≈ 135 m
Therefore, length of the fence required = 132 m

Jasmine took out a college loan of $55,000.00 for college for 10 years. The interest rate
is 4 7%. What will the total cost of the loan be for 10 years?
Answer:
57,585
Step-by-step explanation:
55,000.x4.7%=2585.
55000.+2585=57,585
Answer:
$57,337.50
Step-by-step explanation:
In order to get the answer we would have to add 55, 000 and 4 [tex]\frac{1}{4}[/tex]% of 55,000 (because of the interest rate). In order to find 4 [tex]\frac{1}{4}[/tex] % we would have to multiply 55, 000 by 0,0425. So now we get the following.
Total cost of the loan = 55,000 + 55,000 x 0.0425 = 55,000 + 2,337.5 =
57,337.5

Answer:
y=2x+1
Step-by-step explanation:
Input X=2 into the function, so y=2(2)+1, which is 5. This matches the table.
Answer:
It's the first one: y= 2x +1
Step-by-step explanation:
If you multiply 2 by 2, you'll get 4. then you add 1. You'll get 5.

For a fairground ride the maximum weight of a person is 100kg to the nearest kg.
What is the maximum a person can weigh to go on the ride safely
Answer:
The maximum a person can weigh to go on the ride safely is 100.5 kg
Step-by-step explanation:
The specification for the maximum weight of each person that goes on the ride = 100 kg
Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;
[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg

The graph of a system of two linear equations is shown. How many solution does the system of equation have?
A. No Solution
B. Infinitley Many Solutions
C. Two Solutions
D. One Solution
Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
Write an equation of the line that passes through (1, 2) and is perpendicular to the line y=13x+4.
Answer:
Step-by-step explanation:
y=-1/13x since it is perpendicular flip it and make it negative
Answer:
y = -1/13x + 27/13
Step-by-step explanation:
A perpendicular line will have the opposite reciprocal and sign.
So the perpendicular line slope to y = 13x + 4 would be -1/13
NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT
2 = -1/13(1) + b (b represents the y- intercept)
2 = -1/13 + b (add 1/13 to both sides)
y = -1/13x + 27/13 is the perpendicular line.
Hope this helps ya!!
A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the length of the third side if the second side is length s?
2s - 10
2s + 10
s - 10
s + 10
Answer:
side - equation - measurement
1st side - 2s - 65 - 55cm
2nd side - s - 60cm
3rd side - s - 10 - 50cm
Step-by-step explanation:
total = 165
side - s
1st side = 2s - 65
2nd side = s
3rd side = s - 10
1st side + second side + 3rd side = 165
2s - 65 + s + s - 10 = 165
2s + s + s - 65 - 10 = 165
4s - 75 = 165
4s = 165+ 75
4s = 240
s = 60
1st side = 2s - 65
= 2(60) - 65
= 120 - 65
= 55cm
2nd side = s
= 60cm
3rd side = s - 10
= 60 - 10
= 50cm
3rd side is represented by s - 10 as it is less than the second side by 10cm hence taking away the 10 from the side forming the equation s - 10
Answer:
s-10

Answer:
43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)
38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)
19 is what goes in the box
A store has apples on sale for $15.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $60.00? Complete the explanation.
The cost per pound of the apples on sale is $15.00
.
You can buy __ pounds of apples for $60.00.
Since 1 pound = 16 ounces, so there are about __ apples in each pound.
You can buy approximately __apples for $60.00.
Answer:
24 pounds of apples for $60
about 3 apples per pound
about 72 apples for $60
Step-by-step explanation:
$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds
5 out of 16 ounces equals about 3 apples per pound
24 pounds, with 3 apples in each pound, equals 72
Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15
