Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50
Simplify:
√144a^2b^4
A) 12ab
B) 12a^2b^4
C) 12ab^2
D) 12b√a
Answer:
Option C
Step-by-step explanation:
[tex] \sqrt{144 {a}^{2} {b}^{4} } [/tex]can be written as[tex] \sqrt{144 \times {a}^{2} \times {b}^{4} } [/tex]
[tex] = > \sqrt{144} \times \sqrt{( {a}^{2}) } \times \sqrt{( {b}^{4}) } [/tex]
[tex] = > 12 \times {a}^{ \frac{2}{2} } \times {b}^{ \frac{4}{2} } [/tex]
[tex] = > 12a {b}^{2} [/tex]

You check 20 batteries. Fourteen batteries do not have a charge. Out of the next 70 batteries that you check, how many would you expect to not have charge?
Answer:
Solution:
Check batteries=20
Battreies do not have charge=14
Out of the next batteries that you check=70
Expect to not have charge=30
Answer is 30.
Step-by-step explanation:
Number of batteries do not have charge from 20 batteries is 49 batteries
Numeric number based problem:What information do we have?
Number of batteries do not have charge from 20 batteries = 14 batteries
Using ration of total batteries to do not have charge batteries
Number of batteries do not have charge from 70 batteries = 70[14/20]
Number of batteries do not have charge from 70 batteries = 7[7]
Number of batteries do not have charge from 20 batteries = 49 batteries

We use GCD to solve this
the GCD of 32 and 24 = 8
8 is the greatest number of teams.
each team must have equal number of boys and girls so divided by two
8/2 = 4
4 girls and 4 boys

Answer and Step-by-step explanation:
You're told to find the ordered pair of point E.
E is found on the y-axis.
If you count upwards 8 units, you will see that point E is there.
So, Point E is at the coordinate (0, 8), where 0 represents 0 units on the x axis, and 8 represents 8 units up on the y axis.

A garden table and a bench cost S585 combined. The garden table costs S65 less than the bench. What is the cost of the bench?
Answer:
Bench costs $325
Step-by-step explanation:
Try setting up an equation
x = cost of garden table
y = cost of bench
equation 1: x + y = 585
We also know that the table costs 65 dollars less than the bench.
cost of garden table = bench - 65
or
equation 2: x = y - 65
Now just substitute equation 2 into equation 1
(y-65) + y = 585
and solve for y
2y-65 = 585
2y = 585 + 65 = 650
y = 325 = cost of bench

A car driving cross-country traveled 180 mites in 4 hours. At this rate of speed, how many mites further will the car travel in the next 3 hours?
Answer:
I'm sure you mean miles, but the car will travel 135 mites.
Step-by-step explanation:
(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

b) x = 12 y = 5
Step-by-step explanation:
a) since both equations begin with 'y =' you can set them equal to each other
4x - 6 = x - 8
3x = -2
x = -2/3
sub x value to find y:
y = 4(-2/3) - 6
= -8/3 + (-18/3)
= -26/3
