Solve for x: 1/3(21-3x)=1/2(8-4x)
Answer:
x = -3
Step-by-step explanation:
[tex] \frac{1}{3} -(21 - 3x) = \frac{1}{2} (8 - 4x)[/tex]
[tex]21 - 3x = 3(4 - 2x)[/tex]
[tex]21 - 3 x = 12 - 6x[/tex]
[tex] - 3x + 6x = 12 - 21[/tex]
[tex]3x = - 9[/tex]
[tex]x = - 3[/tex]
Which is the graph of f(x) = 1/4 (4)^x ?
Answer:
The only graph that is fully shown.
Step-by-step explanation:
I did the math and the points check out.
The table below represents a function.
what could be the equation of the function?
===============================================================
Explanation:
Pick any two rows from the table to form the (x,y) points. I'll pick the first two rows.
Use the slope formula to find the slope of the line through (-6,9) and (-4,6)
m = (y2-y1)/(x2-x1)
m = (6-9)/(-4-(-6))
m = (6-9)/(-4+6)
m = -3/2
m = -1.5
Of the four answer choices, only choice C has a slope of -1.5 so that must be the final answer. Note how the y intercept is b = 0 due to the point (0,0).
So y = -1.5x can be written as y = -1.5x+0; however, it's easier to go with the first option.
As a check, let's try something like x = 2
y = -1.5x
y = -1.5*2
y = -3
This verifies the second to last row of values. I'll let you check the other rows.

HELP QUICK PLEASE !!!
WILL GIVE BRAINLIEST !
Answer:
theta = 4.5642792103077898247
Step-by-step explanation:
0 <= theta < 2Pi sin(theta) = 1/2
so
2Pi sin(theta) = 1/2
Pi sin(theta) = 1/4
sin(theta) = 1/(4Pi)
sin(theta) = .0795774715459
theta = arcsin(.0795774715459) = 4.5642792103077898247

a mans age today is four years less than five times the age of his oldest son. let a represent the son's age. write an expression to represent the man's age.
Answer:
m = 5s - 4
Step-by-step explanation:
Man = m
Son = s
the mans age is 4 years less than 5 times his sons age
5 times his sons age is 5s
4 less than that is 5s - 4
The man's age is 5s - 4 or m = 5s - 4

Answer and Step-by-step explanation:
1-6
a.
What you can do is plug in 6 and start by doing the first machine first, then the second. If this doesn't work, do the second machine, then the first machine.
The order that works is second machine, then first machine.
Second Machine:
y = [tex](6)^{2} -6[/tex] = 36 - 6 = 30
Plug into first machine now.
First Machine:
y = [tex]\sqrt{(30) - 5} = \sqrt{25} = 5[/tex]
We see that the result is 5.
b. If we were to do the order of second machine, then first machine, we will never get a negative result (or -5 for that matter), due to the fact that you can't algebraically square root a negative number.
However, if we were to do the order of first machine, second machine, we can get a negative number. To get -5, we plug in 6 for x in the first machine, getting an answer of 1. We plug this into the second machine, getting 1^2 - 6, which results in -5.
1-7. The absolute value of a value is the positive version of that value.
a. |54| = 54
b. [tex]-|-7\frac{3}{5}|[/tex] = [tex]-7\frac{3}{5}[/tex]
c. |3| - |-1| = 3 - 1 = 2
d. |2.2 - 5.13| = |-2.93| = 2.93

b. The amount of squares on each side of the figure increases by 1.
c. There would be 1 square, because we know that the pattern is there is 2 squares added to the next figure, 1 at each end. If we go back a figure, we take away 2 squares.
1-9.
a. -42 - 17 = -59
b. 8 - (-9) = 8 + 9 = 17
c. 8(-9) = -72
d. -42 ÷ (-7) = 6
e. -2(-3)(-4) = 6(-4) = 24
f. -18 - 7 = -25
g. [tex](-5)^{2}[/tex] = 25
h. [tex]-5^{2} = -(5)^2 = -(25)[/tex] = -25
i. [tex]\sqrt{49}[/tex] = 7
1-10. x = 2 Plug 2 in for x, then solve.
a. y = 7 - 3(2) = 7 - 6 = 1
b. y = [tex](2)^2 -1[/tex] = 4 - 1 = 3
c. y = [tex]\frac{18}{2}[/tex] = 9

A new cars salesperson, sold an average of $59,699 per day for the first 4 days she worked. The next 11 days she worked, she sold an average of $49,221. How much did she sell on average per day over the entire time she worked??
Answer:
5,000
Step-by-step explanation:
Solve using a weighted average like so:
{ (6 days)($34,000) + (4 days)($45,000) }/(6 days + 4 days) = $38,400
It doesn't appear as if the correct answer is listed in the choices? You can tell from the information given that the answer must be between $34,000 & $45,000!
Which of the following fractions has the greatest value?
3/4
5/8
5/6
5/9
3/7
We can see that 420/504 is the largest value among the fractions. the fraction 5/6 has the greatest value.
To determine which fraction has the greatest value, we can compare the fractions by finding a common denominator and comparing the numerators.
Let's find a common denominator for all the fractions, which is the least common multiple (LCM) of the denominators.
The denominators are 4, 8, 6, 9, and 7.
The LCM of 4, 8, 6, 9, and 7 is 504.
Now, let's convert each fraction to have a denominator of 504:
3/4 = (3/4) * (126/126) = 378/504
5/8 = (5/8) * (63/63) = 315/504
5/6 = (5/6) * (84/84) = 420/504
5/9 = (5/9) * (56/56) = 280/504
3/7 = (3/7) * (72/72) = 216/504
Comparing the numerators, we can see that 420/504 is the largest value among the fractions.
Therefore, the fraction 5/6 has the greatest value.
