are they being multiplied or added or subtracted?
Answer:
(3, -1)
Step-by-step explanation:
3x +y = 8
-3x =-3x
Y=-3x +8 Substitute into 1st equation y=-3x+8
2x-7(8-3x+8)= 13 -3(3) + 8
2x-56+21x= 13 -9 +8
23x-56 =13 y = -1
+56= +56
23x = 69
23 23
x = 3
solution (3, -1)

Solving
[tex]\frac{x}{-6}[/tex] ≥ 12
Multiply both sides by - 6 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.
x ≤ - 72
Since x can equal 72 then there is a closed circle at x = - 72
Since x is less than 72 then the line points to the left.

Chris wants to ride on the Colossal Coaster at the amusement park. Admission to the park
costs $6 and each ride on the roller coaster costs an additional $0.50. Chris wants to spend less
than $12.50 in all. Find the number of times that Chris can ride on the roller coaster.
Solve using inequalities
Answer:
He can ride it 4 times
Step-by-step explanation:
Answer:
12 times
Step-by-step explanation:
$6 + $0.50 (x) < $12.50
x is the amount of times he can ride. Since he wants to spend less then 12.50 then he can't go more then 13 times but 13 is spending all his money so 12 times is $0.50 less then his specified amount he wants to spend.

15% of 95? and 3 1/2% of 100?
Answer:
15% of 95-14.25
3 1/2% of 100-3.5
Step-by-step explanation:
Answer:
15% of 95= 14.25
3 1/2% of 100= 3.5
Step-by-step explanation:
3 1/2% of 100= 3.5, because 1% of 100=1
15% of 95=14.25 because 10% = 9.5 and 5% of 95=4.75
4.75+9.5= 14.25

Answer:
1. 0.6 and 3/5
2. 9/20
3. 44%
4. 6/8, 80%, 17/20, 0.92
5. 1/2
Step-by-step explanation:
1. 0.6 is equal to 60% because it is both 60 out of 100.
3/5 times 20 is also equal to 60 out of 100.
2. 45% as a fraction is 9/20
3. 22/50 times 2 is 44/100, which is also 44%
4. 6/8 as a percent is 75%, and then 80%, 17/20 as a percent is 85%, and 0.92 as a percent is 92%.
5. 600 out of 1320 is roughly one half.

f(x) = log10 (x) + 5
Answer:
Find the asymptotes.
Set the argument of the logarithm equal to zero.
x+5=0 . Subtract 5
from both sides of the equation. x=−5
The vertical asymptote occurs at x=−5
Vertical Asymptote: x=−5
Find the point at x=−4
Replace the variable x with −4
in the expression.
f(−4)=log((−4)+5)
Simplify the result. Add −4 and 5
f(−4)=log(1) Logarithm base 10 of 1 is 0
f(−4)=0
The final answer is 0
Convert 0 to decimal. y=0
Find the point at x=5. Replace the variable x with 5
in the expression.
f(5)=log((5)+5)
Simplify the result. Convert 1 to decimal. y=1
Find the point at x=−3
Replace the variable x with −3
in the expression.
f(−3)=log((−3)+5)
Simplify the result.
log(2) . Convert log(2) to decimal. y=0.30102999
The log function can be graphed using the vertical asymptote at x=−5 and the points (−4,0),(5,1),(−3,0.30102999)
Vertical Asymptote: x=−5

Identify the sequence below as arithmetic, geometric, or neither. Then find the next two
terms.
15, 19, 23, 27,
The next term in the sequence, as, is?
The next term in the sequence, as is?
The given sequence 15, 19, 23, 27 is arithmetic and 31 and 35 are the next terms of sequence.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The given sequence is 15, 19, 23, 27
An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term.
Common difference=4
a is the first term which is 15
The standard form is aₙ=a+(n-1)d
We have to find the 5th term
a₅=15+(5-1)4
=15+16
=31
Now a₆=15+(6-1)4
=15+20
=35
Hence, the given sequence 15, 19, 23, 27 is arithmetic and 31 and 35 are the next terms of sequence.

Hello!
[tex]\large\boxed{x = 21}[/tex]
[tex]\frac{-x}{3} + 2 = -5[/tex]
Begin isolating for x by subtracting 2 from both sides:
[tex]\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7[/tex]
Further simplify by multiplying both sides by 3:
[tex]\frac{-x}{3} * 3= -7 * 3\\\\-x= -21[/tex]
Multiply both sides by -1 to cancel out the -x:
[tex]-x(-1) = -21(-1)\\\\x = 21[/tex]
