Answer:
Gift card
Step-by-step explanation:
Given
Function 1 and 2
Required
Which has a negative slope
For the first function (Gift card), we have the following observation.
As x increases from 0, 1, 2 and then 3
The values of y keep reducing
This means that the gift card function has a negative slope
For the second function (calculator rental)
We have:
[tex]c = 10 + 5m[/tex]
The slope of function [tex]y =mx + b[/tex] is m
So, by comparison
[tex]m=5[/tex]
5 is positive,
This means that the gift card function has a negative slope

8 over 9 equal
Step-by-step explanation:
4*1 = 4
this indicates multiplication
8/9 = 0.88888888888 which when simplified would go back to 8/9 or .889
8 "over" 9 indicates division!
Jeff can build 7 birdhouses in 5 hours. Use a
proportion to find out how long it would take
him to build 30 birdhouses. (Round answer to
nearest whole number)
Answer:
21 hours
Step-by-step explanation:
We can use a ratio to solve
7 houses 30 houses
------------- = --------------
5 hours x hours
Using cross products
7x = 5*30
7x = 150
Divide by 7
7x/7 =150/7
x =21.42857143
Rounding to the nearest whole number
x = 21 hours
simplify 15 to the power of 18 over 15 to the power of 3
Answer:
15^18/(15^3)=15^15
Step-by-step explanation:
rule for quotients of similar bases with different exponents is:
(a^c)/(a^b)=a^(c-b)
15^18/(15^3)=15^15
Plzzz help I don’t have a lot of time
Answer:
7
Step-by-step explanation:
It’s a right angle, so you can add the two expressions togther to get 90, then isolate x.
(8r-6)+(5r+5)=90
13r-1=90 (combine like terms)
13r-1+1=90+1 (add 1, addition property of equality)
13r=91
13r/13=91/13
r=7
Which of the following illustrates the truth value of the given conditional statement?
p. 10 > 7
q. 10 > 5
p-~q
Answer:
T T → T
Step-by-step explanation:
Given :
p = 10 > 7
q = 10 > 5
Evaluating if the statements are true :
p = 10 > 7, This is TRUE, Because 10 is truly greater Than 7
q = 10 > 5, This is TRUE, Because 10 is truly greater Than 5
The statements are both True statements :
p = True ; q = True
True and True = True
T & T = T
T T → T

Answer:
a = 153.5 yd²
Step-by-step explanation:
horizontally divide the figure into a tringle and a trapezoid
triangle
a = (1/2)bh
a = (1/2)(19)(7)
a = 66.5
trapezoid
a = (b₁ + b₂)/2 * h
a = (19 + 10)/2 * (13 - 7)
a = 87
Combined
a = 66.5 + 87
a = 153.5

Answer:
(0, 3), (4, -5)Step-by-step explanation:
y = x² - 6x + 3y = -2x + 3Solve by substitution:
x² - 6x + 3 = -2x + 3x² - 4x = 0x(x - 4) = 0x = 0 ⇒ y = -2*0 + 3 = 3x = 4 ⇒ y = -2*4 + 3 = -5What is distributive property in math?
Answer:
The distributive property is one of the most frequently used properties in math. The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
distributive property is multiplying a number by a sum is the same as doing each multiplication separately.
for example: 2 (4 + 3 )
2 x 4 = 8
2 x 3=6
8+6=14

Step-by-step explanation:
what that two numbers when multiplied give 600 and when added give 59
Answer:
Step-by-step explanation:
Let the 2 numbers be x and y
From the problem we have that
x * y = 600 and x + y = 59
From x + y = 59 -> x = 59 - y
Plug x = 59 - y to x * y = 600 we have
(59 - y) * y = 600
-> 59y - y^2 = 600
-> -y^2 + 59y - 600 = 0
-> y = [tex](59 - \sqrt{1081})/2[/tex] or [tex](59 + \sqrt{1081})/2[/tex]
Then we could plug the answers in and find x because x = 59 - y
What is the solution of the equation, 8y = 4?
A. y = 1/2
B. y = 2
c. y = 12
D. y = 32
Answer: A, which is y = 1/2
Step-by-step explanation: To find the value of y, you would need to divide both of the sides by 8. This makes it so that 8y turns into just y. After you do this, you would find an answer of y = 1/2. Hope this was helpful! :)
Answer:
y = 1/2
Step-by-step explanation:
8y = 4
Divide each side by 8
8y/8 = 4/8
y = 1/2
A researcher collects demographic data on the marital status of the study subjects. The variable is measured as the number of years married on a scale of 0-75. What would be the most appropriate measure of central tendency
Answer:
Probably "Median"
The mode doesn't really make sense,
and "mean" would probably be skewed by people who get divorced quickly
I would suggest "Median" the number of years that 1/2 of the couples are above and 1/2 below
Step-by-step explanation:
Help me fast 50 points!!!!!!!!
Answer:
30
Step-by-step explanation:
There are 14 data points on the plot
The median is the middle value, which is between the 7th and 8th data points
Since it is even, we find the average of the 7th and 8th data points
Add the 7th and 8Th data points values and divide by 2
( 30+30)/2 = 60/2 = 30
The median is 30
Answer:
30
Step-by-step explanation:
Middle numbers are 30 and 30 so you add them and then divide by two:
[tex]\frac{30 + 30}{2}[/tex] = [tex]\frac{60}{2}[/tex]= 30
Please I need help in finding the diameter

Express 240g as a percentage of 2.5kg
Answer:
0.1%
Step-by-step explanation:
Given that 240 g of 2.5 kg
We have to express this in percentage
But we know that 1 kg = 1000 g, So first convert 2.5 kg to g
2.5 kg = 2.5 x 1000 g = 2500 g
The formula of "a" % of "b" is given as:
[tex]percentage= \frac{a}{b}[/tex] × 100
Hence, 240 g as a percentage of 2500 g is given as:
[tex]= \frac{250}{2500}[/tex] × [tex]100[/tex]
= [tex]\frac{1}{10}[/tex] = 0.1
Thus, the answer is 0.1 %
