Can someone plzzz tell me if #14. b. is right plzz
Answer:
14b.) RS = 60; ST = 36; RT = 96
Step-by-step explanation:
Since you have correctly solved for y = 7, all you need to do for b is to plug in y.
RS = 8(7) + 4 = 60
ST = 4(7) + 8 = 46
(You can add RS and ST or plug in for y for RT)
RT = 15(7) - 9 = 96

x +y = y-m
what is m
Answer:
m = -x
Step-by-step explanation:
x +y = y-m
subtract y on both sides which will cancel them out, we are left with
x = -m
multiply both sides by -1 to get rid of the -m
x × -1 = -x, -m × -1 = m
final answer: m = -x

Answer:
Y = 1/4x+2
Step-by-step explanation:
So to find the slope of the line you can use rise/run to do this you can pick two points and count how may squares is going up and how many is going to the left.
For this problem the two points can be (0,2) and (4,1) and if we count how many squares it goes up by we can see its 1 and if we count from (0,2) to (4,1) horizontally the space is 4

7x+y= 4
Substitution
Answer:
3x-4y=15
7x+y=4
Solve7x+y=4 for y:
7x+y=4
7x+y+−7x=4+−7x (Add -7x to both sides)
y=−7x+4
Step: Substitute −7x+4 for y in 3x−4y=15:
3x−4y=15
3x−4(−7x+4)=15
31x−16=15 (Simplify both sides of the equation)
31x−16+16=15+16 (Add 16 to both sides)
31x=31
(Divide both sides by 31)
x=1
Step: Substitute 1 for x in y=−7x+4:
y=−7x+4
y=(−7)(1)+4
y=−3(Simplify both sides of the equation)
Answer: x=1 and y=−3

Lenore lives in a state where sales tax is 10%. This means you can find the total cost of an item, including tax, by using the expression c + 0.10c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
Function is
f(c)=c+0.10cPut 84.00$

Evaluate the equation below.
p + 333 = 350
Answer:
17
Step-by-step explanation:
350-333 = 17
p = 17
Or...
Subtract 3 from both sides of the equation
p+333=350
+333−333=350−333
p = 17
Answer:
p=17
Step-by-step explanation:
p+333 = 350 (subtract 333 on both sides)
350-333 = 17
p = 17

The water jug for a basketball team was 7/8 full of water after the game the 8 players poured out 3/5 of the water in the jug. How much water is still there
The water left in the jug after the players poured out some water is 11/40
How to subtract fractionQuantity of water in the jug = 7/8Water poured out of the jug = 3/5Water remaining = Quantity of water in the jug - Water poured out of the jug
= 7/8 - 3/5
= (35-24) / 40
= 11/40
Therefore, the water still left in the jug us 11/40
