Jacob earns $7.25 an hour at his part-time job, and earns $9 each time he mows the lawn for his mother. He graphs the amount of hours he works at his job (x) and the number of lawns he mows (y) to determine how to earn at least $300. Which type of boundary line should he use in his graph?
A A dotted boundary line, because the values on the line should not be included in the solution set.
B A solid boundary line, because the values on the line should not be included in the solution set.
C A dotted boundary line, because the values on the line should be included in the solution set.
D A solid boundary line, because the values on the line should be included in the solution set.

A video game system and several games are sold for $652. The cost of the games is 3 times as much as the cost of the system. Find the cost of the system and the cost of the games.
Cost of the video game system: $
Answer:
The cost of the system is $163 and The cost of the games is $489
Step-by-step explanation:
∵ A video game system and several games are sold for $652
∵ The cost of the games is 3 times as much as the cost of the system
→ Assume that the cost of the system is $x
∵ The cost of the system = x
∴ The cost of the games = 3 × x = 3x
∵ The total cost of the system and the games = 652
→ Equate the sum of the cost of the system and the cost of the games
by 652
∴ x + 3x = 652
→ Add the like terms in the left side
∴ 4x = 652
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}=\frac{652}{4}[/tex]
∴ x = 163
∵ The cost of the system = x
∴ The cost of the system is $163
∵ The cost of the games = 3x
∴ The cost of the games = 3(163) = 489
∴ The cost of the games is $489

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
P = 2(w + h)
W = 12 correct to the nearest whole number
h = 4 correct to the nearest whole number
Work out the upper bound for the value P
(urgent please)
Answer:
p=32
Step-by-step explanation:
4+12=16
16×2=32
p=32
After substituting W = 12, h = 4, in the equation P = 2(w + h), P = 32
What is upper bound?"An element greater than or equal to all the elements in a given set."
What is equation?"It is an expression which contains an equal symbol."
For given question,
Given equation: P = 2(w + h)
W = 12, h = 4
After substituting these values in given equation,
⇒ P = 2 × (12 + 4)
⇒ P = 2 × 16
⇒ P = 32

A drive in movie charges $9 per car plus $2 per person in the car. The total cost for going to the drive in movie when you go on x people are in the car is f(x) = 2x + 9. How will the graph of this function change if the cost per car is changed to $6 ?
Step-by-step explanation:
f(x)= 2x + 9
Cost per car
Change 9 to 6.
f(x) = 2x + 6
Because 9 was the y-intercept and it was changed to 6, or 3 units down, the function would be be translated 3 units down

Solve the system by substitution, solve by elimination. Please do both & explain. Don’t answer if you don’t know. Will mark brainliest. Thank you :)
(1)
[1] x + 5y - 4z = -10
[2] 2x - y + 5z = -9
[3] 2x - 10y - 5z = 0
Eliminate x by adding -2[1] to [2], and adding -1[2] to [3]:
-2(x + 5y - 4z) + (2x - y + 5z) = -2(-10) + (-9)
-2x - 10y + 8z + 2x - y + 5z = 20 - 9
[4] -11y + 13z = 11
-(2x - y + 5z) + (2x - 10y - 5z) = -(-9) + 0
-2x + y - 5z + 2x - 10y - 5z = 9
[5] -9y - 10z = 9
Eliminate y by adding -9[4] to 11[5]:
-9(-11y + 13z) + 11(-9y - 10z) = -9(11) + 11(9)
99y - 117z - 99y - 110z = -99 + 99
-227z = 0
z = 0
Plug this solution into either [4] or [5] and solve for y :
[5] -9y - 10(0) = 9
-9y = 9
y = -1
Plug them both into either of [1], [2], or [3] and solve for x :
[1] x + 5(-1) - 4(0) = -10
x - 5 = -10
x = -5
(2)
[1] 2x - y + z = -4
[2] z = 5
[3] -2x + 3y - z = -10
Substitute [2] into [1] and [3]:
2x - y + 5 = -4
[4] 2x - y = -9
-2x + 3y - 5 = -10
[5] -2x + 3y = -5
Solve [4] for y :
2x - y = -9
2x + 9 = y
Substitute this into [5] and solve for x :
-2x + 3(2x + 9) = -5
-2x + 6x + 27 = -5
4x = -32
x = -8
Plug this into either [4] or [5] to solve for y :
[4] 2(-8) - y = -9
-16 - y = -9
y = -5

The value of the variable x will be 2. Then the radius of the circle will be 5.
What is the area of a circle?Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is x + 3. And the area of the circle is 25π. Then the equation will be
25π = π(x + 3)²
(x + 3)² = 25
x + 3 = 5
x = 5 - 3
x = 2
Then the radius will be
r = x + 3 = 2 + 3 = 5
The value of the variable x will be 2. Then the radius of the circle will be 5.
