Carlos spends at least 45 minutes each day on the internet. Write an inequality which could be used to describe the amount of time,x, that Carlis spends on the internet.
Answer:
x ≤ 45 mins
Step-by-step explanation:
At least can be changed into less than or equal to.
Also, at most would be greater than or equal to.
Therefore, you simply need a less than or equal to sign.
As the music plays,the volume changes In the beginning of the piece can be modeled by the equation s=10Ix-4I+50 where s represents the sound level in decibels and x represents the number of measures of music played. explain in words each step to find the following equation at what number(s) measures played would the sound level be at 80
Answer:
-127
Step-by-step explanation:
s = 101x-41+50
80 = 101x - 4+ 50
-101x
-181 = x - 4 +50
-181 = x -54
+ 54
-127 = x

using the fact that the black triangle represents the mean and/or the understanding of what a deviation is, explain why this balancing beam would stay balanced went to Blue circles are removed. Be thorough with your explanation and use Multiple sources of evidence
Answer: the left side is balanced with the right side
Step-by-step explanation:
Left side:
1 barrel (located at 2) is 1 unit from the fulcrum (triangle) → 1(1) = 1
2 barrels (located at 1) are 2 units from the fulcrum (triangle) → 2(2) = 4
1 barrel (located at 0) is 3 units from the fulcrum (triangle) → 1(3) = 3
Total = 8
Right side:
1 barrel (located at 6) is 3 units from the fulcrum (triangle) → 1(3) = 3
1 barrel (located at 8) is 5 units from the fulcrum (triangle) → 1(5) = 5
Total = 8
The distribution of the weight on the left side equals the distribution of weight on the right side so the beam is balanced.

The product of 5 and the difference of 9 and a number.
Answer: 5(9-x)
Step-by-step explanation:
Based on the question, let the number be represented by x.
From the question, we are informed that we've a product, this means that we need to multiply 5 by the difference of 9 and x.
In the order of operations, we've to multiply first before we subtract. Therefore, the equation will be written as:
= 5 × (9 - x)
= 5(9-x)

In the diagram m<8=11y+7 and m<3=y+17.What is m<2
Answer:
C. 150
Step-by-step explanation:
Given:
m<8 = 11y + 7
m<3 = y + 17
Required:
Find m<2
Solution:
m<8 + m<3 = 180 (supplementary angles and linear pair theorem)
11y + 7 + y + 17 = 180 (substitution)
Collect like terms
12y + 24 = 180
Subtract 24 from each side
12y = 180 - 24
12y = 156
Divide both sides by 12
y = 156/12
y = 13
m<2 = m<8 (alternate exterior angles are congruent)
m<2 = 11y + 7
Substitute y = 13 into the equation
m<2 = 11(13) + 7 = 143 + 7
m<2 = 150°
A line has a slope of - 1/4 and passes through point(-5/4,1)
What is the equation of the line?
Answer:
y= -1/4x - 1/4
Step-by-step explanation:
y - y1 = m(x - x1)
y - 1 = -1/4 (x -(-5/4))
y - 1 = -1/4x - 5/4
y = -1/4x - 1/4

If you multiply a number by four and then subtract negative ten, the difference is negative twenty-two. What is the number?
Answer:
n=-3
Step-by-step explanation:
To solve start with the 4n-10=-22
+10 to both sides and you get 4n=-12
Divide each side by 4 and you get n=-3
To check plug -3 in for n and you'll get the -2 once you solve it.

If the sales tax in Texas is 8.25%, what is the
total cost of a new backpack for $36?
Answer:
[tex]Total\ Cost = \$38.97[/tex]
Step-by-step explanation:
Given
[tex]Backpack = \$36[/tex]
[tex]Sales\ Tax = 8.25\%[/tex]
Required
Determine the Total Cost
Total cost is calculated as thus
[tex]Total\ Cost = Backpack + Backpack * Sales\ Tax[/tex]
[tex]Total\ Cost = \$36 + \$36 * 8.25\%[/tex]
[tex]Total\ Cost = \$36 + \$2.97[/tex]
[tex]Total\ Cost = \$38.97[/tex]

Answer:
Step-by-step explanation:
1) Composite functions are function of two or more functions to serve as one function. For example, given d(x) and g(x), we can write both as composite function as d(g(x)). We can call it function of a function. Hence, from the following function, the following options except option B are composite.
d(x)g(x) is the product of the two functions not a composite.
Option B is correct.
b) Given h(x) = x-1 and d(x) = 7x+3
H(3) = 3-1
H(3) = 2
d(2) = 7(2)+3
d(2) = 14+3
d(2) = 17
h(3)+d(2) = 2+17
h(3)+d(2) = 19 (option D)
c) Given t(x) = -x² + 7x + 1 and r(x) = 5x² - 2x + 8, we are to first find the function
t(x)-r(x)
t(x)-r(x) = -x²+7x+1-5x²+2x-8
t(x)-r(x) = -x²-5x²+7x+2x+1-8
t(x)-r(x) = -6x²+9x-7
Substitute x as 2
(t-r)(2) = -6(2)²+9(2)-7
t-r (2) = -6(4)+18-7
(t-r)(2) = -24+11
(t-r)(2) = -13 (option C)
d) If h(x) = 4x + 2 and g(x) = 3x - 1,
h-g = 4x+2-(3x-1)
h-g = 4x+2-3x+1
h-g = 4x-3x+2+1
h-g = x+3
h-g(4) = 4+3
(h-g)(4) = 7
e) If g(x) = x - 4 and h(x) = x + 5, we are to find f(x)h(x)
h(x)g(x) = (x-4)(x+5)
h(x)g(x) = x(x)+5x-4x-20
h(x)g(x) = x²+x-20
Hence the product of h(x) and g(x) is x²+x-20. Option D is correct
