42 = -7 ( z-3)
whats z?
Answer:
z = -3
Step-by-step explanation:
42 = -7 ( z-3)
42 = -7z + 21
21 = -7z
z = -3
Answer and Step-by-step explanation:
We have to solve for z. That means everything that is next to z has to move to the other side of the equation.
First, divide -7 from both sides of the equation.
-6 = z - 3
Now add 3 to both sides of the equation.
-3 = z
z is equal to -3.

What is the solution set of - lxl= -8?
Answer:
8
Step-by-step explanation:
The absolute value of |x| is x
-x = -8
Distribute the - on the other side but since two negatives make a positive:
- and - = +
x = 8

tan6x nhân tan7x= -1
Recall that
• tan(x) = sin(x) / cos(x)
• sin(x) sin(y) = - 1/2 (cos(x + y) - cos(x - y))
• cos(x) cos(y) = 1/2 (cos(x + y) + cos(x - y))
Then we can write
tan(6x) tan(7x) = (sin(6x) sin(7x)) / (cos(6x) cos(7x))
tan(6x) tan(7x) = - (cos(13x) - cos(x)) / (cos(13x) + cos(x))
Make this replacement in the original equation and simplify:
tan(6x) tan(7x) = -1
- (cos(13x) - cos(x)) / (cos(13x) + cos(x)) = -1
(cos(13x) - cos(x)) / (cos(13x) + cos(x)) = 1
cos(13x) - cos(x) = cos(13x) + cos(x)
2 cos(x) = 0
cos(x) = 0
Solving for x gives
x = π/2 + nπ = (2n + 1)π/2
where n is any integer. However, since 2n + 1 is odd, for any odd multiple of π/2, we would end up with
tan(6 (2n + 1)π/2) = tan((2n + 1)×3π) = tan(odd multple of π/2)
since odd×odd = odd, and cos(odd multiplie of π/2) = 0, which would make tan(6x) undefined.
Therefore there are no solutions to this equation.

Amy regularly works 20 hours per week at Hook's Dry Cleaners from Monday through Friday. She earns $13.10 per hour and receives double time pay for working Sundays. Next week she will work her regular 20 weekday hours, and an additional 8 hours on Sunday. What will her total gross pay be for the week?
please show work thanks!
Answer:
$471.60
Step-by-step explanation:
The double time rate is not specified in the question. But I will assume it's 2 times the normal rate. Therefore...
13.10 x 20 + 8 x (13.10 x 2)
Answer = $471.60
Claude's net pay for the month was $985.50.
If his gross pay is $1350.00, his net pay is what percent of the gross pay?
Hello ;)
We have :
Claude's net pay → $985.50
Claude's gross pay → $1350.00
We know that the gross pay represents 100 % of the salary.
So :
$1350.00 ⇔ 100 %
$985.50 ⇔ ? %
? = 985.5 × 100 ÷ 1350 = 73 %
Claude's net pay is 73 % of the gross pay.
:-)
Based on his net pay being $985.50 and his gross pay being $1,350.00, the net pay is 73% of the gross pay.
To find out how much of the percentage of something a variable is, you make the variable the numerator and the other measure the denominator.
In this instance that would be:
= Net pay / Gross pay x 100%
= 985.50 / 1,350 x 100%
= 73%
In conclusion, the net pay is 73% of the gross pay.

Find the 11th term of the arithmetic sequence -5x + 6, -9x + 11, -13x + 16
Answer:
11th term is -45x+56
Answer:
a_11 = -45x + 56
Step-by-step explanation:
An arithmetic sequence has a constant difference which can be found by subtracting a term from the next term.
constant difference = d = -9x + 11 - (-5x + 6)
d = -9x + 11 + 5x - 6
d = -4x + 5
The nth term of an arithmetic sequence is
a_n = a_1 + (n - 1)d
a_11 = a_1 + (11 - 1)(-4x + 5)
a_11 = -5x + 6 + 10(-4x + 5)
a_11 = -5x + 6 - 40x + 50
a_11 = -45x + 56

Can anyone please help me to find the area of this please
9514 1404 393
Answer:
√35 +3√7 -6 . . . square units
Step-by-step explanation:
The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.
Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.
The overall width is the sum of the given partial widths:
width = (√7 -2) + (2) = √7
Then the area of the bounding rectangle is ...
A = LW = (√5 +3)(√7) = √35 +3√7
The area of the upper right empty-space is ...
A = LW = (3)(2) = 6
Then The area of the shaded figure is ...
√35 +3√7 -6

Step-by-step explanation:
11 7/8 can be written as (11 + 7/8). If we find (11+7/8)², we know that √(11+7/8)² = (11+7/8), so we can compare (11+7/8)² with 129 and see which is bigger.
(11+7/8)² = (11+7/8) * (11+7/8)
= 121 + 7/8 * 11 + 7/8 * 11 + (7/8)²
= 121 + 77/8 + 77/8 + (7/8)²
77/8 is greater than 9 (8*9 = 72) but less than 10 (8*10=80). Rounding down to 7, we have
121 + 7 + 7 + (7/8)²
= 135 + (7/8)²
Even when rounding down, (11+7/8)² is greater than 129. Therefore,
129 < (11+7/8)²
square root both sides
√129 < (11+7/8)
We can apply a similar process for the next one.
(3+5/6)² = (3+5/6) * (3+5/6)
= 9 + 5/6 * 3 + 5/6 * 3 + (5/6)²
= 9 + 15/6 + 15/6 + (5/6)²
15/6 is less than 3 (6*3 = 18) but greater than 2 (6*2 = 12). Rounding down to 2, we have
9 + 2 + 2 + (5/6)²
= 13 + (5/6)² > 10
Even when rounding down, (3+5/6)² is greater than 10
(3+5/6)² > 10
square root both sides
(3+5/6) > √10
Write 63 as a product of as many factors a possible. Do not use 1 as a factor.
Answer:
7 x 9 = 63 7 is a FACTOR of 63
9 is a FACTOR of 63
7 and 9 are even DIVISORS of 63
63 is a MULTIPLE of 7 and 9
63 is a PRODUCT of 7 and 9
63 is evenly DIVISIBLE by 7 or 9
Writing 63 as a product of as many factors will be: 7 × 9, 3 × 21, 9 × 7 and 21 × 3.
The factors of 63 include 1, 3, 7,9, 21 and 63.
Since we've been given the information that we should not use 1 as a factor when multiplying according to the question, then the 63 as a product of its factors will be:
3 × 21 = 63
7 × 9 = 63
9 × 7 = 63
21 × 3 = 63

Suppose y varies inversely with x, and y = -1 when x = 6. What inverse variation equation relates x and y?
Answer:
y = -6/xStep-by-step explanation:
Inverse variation equation:
y = k/x, where k - coefficientWe have:
x = 6, y = -1Work out the value of k by substituting the values of x and y:
-1 = k / 6k = -1*6k = -6The equation is:
y = -6/xAnswer:
y = -6/x
Step-by-step explanation:
y varies inversely as x
So, y = k/x, where k is the constant of proportionality.
If y = -1 when x = 6,
Then, -1 = k/6 ===> k = -6
Therefore, y = -6/x

We see that this is an isosceles triangle. This means that two sides are the same length. . We can see that the sides DE and EF are marked with two orange lines, which shows that they are congruent.
We want to find the measure of angle D. We see that our two lines of equal length both create an angle with the hypotenuse DF. Since these lines are the exact same length, they are going to have to create the same angle. Even if you just eyeball it, the angles look to be the same.
So, our measure of angle D is going to be the same as angle F. Let's call this measure m and put it into an equation.
2m+92=180 (sum of all angle measures in a triangle is 180)
Subtract 92 from both sides.
2m=88
Divide both sides by 2
m=44
So, the measure of angle D is B. 44°.
