For each function, what is the output of the given input? For f ( x ) = 4 x + 7 , find f ( 4 ) . 1
Answers
Answer:
let's see what to do buddy...
Step-by-step explanation:
To find the output of a number in a function, we must put it in the equation of the function instead of the x .
So to find output of ( x = 4 ) , we must put 4 instead of x in the equation .
Let's do it :
[tex]f(4) = 4 \times (4) + 7 \\ \\ f(4) = 16 + 7 = 23 \\ [/tex]
So the output number of ( x = 4 ) is 23 .

If the sales tax in Texas is 8.25%, what is the
total cost of a new backpack for $36?
Answers
Answer:
[tex]Total\ Cost = \$38.97[/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]

Answers
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
There are 15 students in my first period class. If 6 of the students in the class are boys, what percent of the students are boys?
A. 60%
B. 25%
C. 40%
D. 30%
Answers
Answer:
C
Step-by-step explanation:
If you were to multiply 15 by 40% it would equal 6.
No. of students in 1st class= 15
No. of boys = 6
Percentage of boys = 6/15 ×100
= 2/3×100
= 40%

Answers
Answer:
The answer is A
Step-by-step explanation:
The first thing to do is see which two lengths of EF and FG equals EG which is 23. If you add together B's options you get -12 and if you add C's options, you get 77. So that leaves us with the options of A and D. From there, just plug in each value of x and see which one gets you the right values. Hope this helps

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
Answers
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.
