Please help me :) Will mark brainliest
Answer:
Option D
Step-by-step explanation:
y = x - 4
y = -3x
x - 4 = -3x
Subtract x from both sides;
-4 = -4x
Divide both sides by -4
x = 1
Substitute x;
y = x - 4
y = 1 - 4
y = -3
(x, y) = (1, -3)
A bag contains 4 yellow balls 5 red balls and 6 blue balls what is the probability of picking a yellow ball
Answer:
4/15
Step-by-step explanation:
there is a total of 15 balls and there is 4 yellow balls
The probability of picking a yellow ball
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
If the bad contains 4 yellow balls 5 red balls and 6 blue balls, the total outcome will be 15 balls
if a yellow ball is selected, the expected outcome will be 4
Pr(selecting a yellow ball) = 4/15
Hence the probability of picking a yellow ball is 4/15

10 bags of chips and 8 soda cans cost $15. 5 bags of chips and 5 soda cans cost $8. How much does a bag of chips cost? How much does a can of soda cost?
Answer:
One bag of chips costs $1.10
One can of soda costs $0.50
Step-by-step explanation:
1. Create a system of equations (b = bags of chips | s = soda)
10b + 8b = 15
5b + 5s = 8
2. Use the Elimination method by multiplying 5b+5s=8 by -2
10b + 8b = 15
-2(5b + 5s = 8)
=
10b + 8b = 15
- 10b - 10s = -16
(10b and -10b will cancel out, so you will only have s left)
=
-2s = -1
Divide by 2
Soda = 1/2, or $0.50
3. Plug in S (0.50) into an equation above and get B by itself
5b + 5(0.50) = 8
=
5b + 2.5 = 8
- 2.5 -2.5
5b = 5.5
Bag of Chips = $1.10

The volume of water in a tank is modeled by the function y = 1.15x3 – 0.1x2 + 2 where x is the number of minutes after the faucet filling the tank is turned on. What is the y-intercept of the graph, and what does it represent in this context? Choose from the drop-down menus.
Given:
The volume of water in a tank is modeled by the function
[tex]y=1.15x^3-0.1x^2+2[/tex]
where, x is the number of minutes after the faucet filling the tank is turned on.
To find:
The y-intercept and what does it represent in this context?
Solution:
We have,
[tex]y=1.15x^3-0.1x^2+2[/tex]
Substituting x=0, we get
[tex]y=1.15(0)^3-0.1(0)^2+2[/tex]
[tex]y=0-0+2[/tex]
[tex]y=2[/tex]
Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.
Answer:
The volume of water in a tank before the faucet filling the tank is turned on.

what is the product of 25 and (6/5n +31/4)
Answer:
30n + 193.75
Step-by-step explanation:
Product means multiplication so 25([tex]\frac{6}{5}n +\frac{31}{4}[/tex])
The first step is distribution of 25 to all numbers in ( ).
25([tex]\frac{6}{5}n[/tex]) is 30 and 25([tex]\frac{31}{4}[/tex]) is 193.75
Now we have the equation 30n + 193.75 which cannot be simplified further since the two variables are not like terms.

1. Sharon and Geordi both worked hard over the summer. Together they earned a total of $525. Geordi earned $75 more than Sharon.
(a) Write a system of equations for the situation. Use s for the amount Sharon earned and g for the amount Geordi earned.
(b) Graph the equations of the system on the graph provided
Answer:
s + g = 575
g = 75 + s
g = 325
s = 250
Step-by-step explanation:
Given that :
Total amount earned by Sharon and Geordi = $525
Also, Geordi earned $75 more than Sharon
Let amount earned by Sharon = s
Amount earned by Geordi = g
Equations :
s + g = 575 - - - equation 1
g = 75 + s - - - equation 2
Put g = 75 + s in equation 1
s + 75 + s = 575
2s + 75 = 575
2s = 575 - 75
2s = 500
s = 250
g = 75 + s
g = 75 + 250
g = 325
