y = -4x + 6
y = -2x - 2
Solve for x and y
Answer:
(4,-10)
Step-by-step explanation:
You set them equal to each other.
You get x=4
Sub in 4 for one of the equations
y=-10
Solve for x in y = -4x + 6.
x = −y/4 + 3/2
Solve for x in y = -2x - 2.
x = −y/2 −1
Nothing can be done with y = -4x + 6 and y = -2x - 2

Answer:
$324 for 72 pints$306 for 36 quartslarger size is better dealStep-by-step explanation:
The cost of 72 pints is 72 times the cost of 1 pint:
72 × $4.50 = $324.00 . . . cost of 72 pints
The cost of 36 quarts is 36 times the cost of 1 quart:
36 × $8.50 = $306.00 . . . cost of 36 quarts
__
The price for quart containers is lower, so the larger size is the better deal.
Buddy and his team have been asked by NASA to make a space shuttle cake (a scale model shaped like the one to the left) for a fundraising event. The original space shuttle has a height of 184 ft and a wingspan of 78 ft. Buddy and his team decide to construct the cake on-site so that they do not have to worry about transporting it. Buddy decides to make a cake with a wingspan of 10 ft and asks one of his decorators, Ivette, to calculate the height of the cake. Ivette decides that the cake should be approximately 4 ft tall.
Answer:
Ivette is wrong and by a lot. The spaceship should be 23.59 feet high
Step-by-step explanation:
The relationship between the spaceship's height and width = 184 feet : 78 feet ≈ 92 : 39 ≈ 9.2 : 3.9. This means that for every 3.9 feet wide, the cake should be 9.2 feet high.
In this case, the spaceship is 10 feet wide, so it should be (10 / 3.9) x 9.2 = 23.59 feet high.
When you make scale drawings or scale cakes, you must keep the same proportions as the original model.

Eli's Diner sold 50 milkshakes last week. 60% of the milkshakes had whipped cream on top. How many milkshakes with whipped cream were sold?
Answer:
30 will be the number of milkshakes had whipped cream on top.
Step-by-step explanation:
Total number of milkshakes sold by Eli's Diner last week = 50
As 60% of the milkshakes had whipped cream on top.
Let x be the number of the milkshakes had whipped cream on top.
[tex]x=\frac{60}{100}\times 50[/tex]
[tex]x=\frac{60}{2}[/tex]
[tex]x=30[/tex]
Therefore, 30 will be the number of milkshakes had whipped cream on top.

Which of the following points would be on the graph of the equation y=−4x+6?(−4, −10)(−4, 22)(1, −10)(1, −2)
Answer:
Only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
Step-by-step explanation:
Given the equation
[tex]y=-4x+6[/tex]
Let us substitute all the given points to check which points satisfy the equation.
Substitute (-4, -10) in the equation
[tex]y=-4x+6[/tex]
[tex]-10=-4(-4)+6[/tex]
[tex]-10=16+6[/tex]
[tex]-10=22[/tex]
As the R.H.S ≠ L.H.S, hence (-4, -10) does not satisfy the equation.
Hence, (-4, -10) is NOT ON THE GRAPH of the equation
Substitute (-4, 22) in the equation
[tex]y=-4x+6[/tex]
[tex]22 = -4(-4)+6[/tex]
[tex]22 = 16+6[/tex]
[tex]22 = 22[/tex]
As the R.H.S = L.H.S, hence (-4, 22) satisfies the equation.
Hence, (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.
Substitute (1, -10) in the equation
[tex]y=-4x+6[/tex]
[tex]-10=-4(1)+6[/tex]
[tex]-10=-4+6[/tex]
[tex]-10=2[/tex]
As the R.H.S ≠ L.H.S, hence (1, -10) does not satisfy the equation.
Hence, (1, -10) is NOT ON THE GRAPH of the equation
Substitute (1, -2) in the equation
[tex]y=-4x+6[/tex]
-2 = -4(1)+6
-2 = -4 + 6
-2 = 2
As the R.H.S ≠ L.H.S, hence (1, -2) does not satisfy the equation.
Hence, (1, -2) is NOT ON THE GRAPH of the equation
Therefore, from the above analysis, we conclude that only the point (-4, 22) is ON THE GRAPH of the equation. Please also check the attached graph.

A deal is a deal, so here is a good one, let's see who gets it right. I had $10.00. My mom gives me $30.00, My dad gave me $30.00. My aunt and uncle give $100.00. I had another $10.00. How much money did I have?
Answer:
$180 in total!
Step-by-step explanation:
10 + 30 + 30 + 100 + 10 = 180
the uncle and aunt gave their money together, it didn't specify that they each gave 100
Answer:
The total amount of money i have is $180.
Step-by-step explanation:
Given information:
The money i have = $10
Mom gives = $30
Dad gives = $30
Aunt and uncle gives = $100
Now i had another $10
The total amount of money (x) i have is the sum of all money i receive.
x = 10+30+30+100+10
x = 180
Hence , the total amount of money i have is $180.
