Is the given value a solution of the inequality?
z + 2 > - 4; z = -8
Answer:
z = -8 is not a solution to the given inequality.
Step-by-step explanation:
Step 1: write the inequality
z + 2 > -4
Step 2: substitute z with the given value
-8 + 2 > -4
Step 3: evaluate the left side
-6 > -4
Step 4: is the last inequality above true or false?
Since -6 is less than -4, -6 > -4 is false.
Answer: z = -8 is not a solution to the given inequality.

In ΔTUV, the measure of ∠V=90°, the measure of ∠T=42°, and UV = 20 feet. Find the length of TU to the nearest tenth of a foot.
Answer:
29.9 feet
Step-by-step explanation:
sin 42= 20/x
X sin 42=20 cross multiply
X sin 42/sin 42 = 20/sin 42 Divide each side by sin 42
X = 20/sin 42 = 29.8895 ~ 29.9 feet

Find the inequality represented by the graph
Answer:
y<or equal to 5/2x + 5
Step-by-step explanation:
when graphing inequalities, the line is solid when the inequality is also "or equal to". also, the less than sign indicates that the area below the line will be shaded. the y intercept is the y value when x is 0, so + 5. the slope, calculated with rise over run, is 5/2x
I need help asap pleaseee
Answer:
Start from 1 and place a point. Go up up 9 rights then right one unit. Place a point and repeat (9 up and one right again)
Step-by-step explanation:
The slope is rise over run.
9 units up and 1 unit to the right.
b is the y-intercept.
(0, 1)
(1, 10)

Could I please have a step by step as well? Much appreciated!
Answer:
[tex]x = 7[/tex]
Step-by-step explanation:
1) Use Division Distributive Property: (x/y)^a = x^a/y^a.
[tex] \frac{1}{ {27}^{x - 8} } = 27[/tex]
2) Multiply both sides by 27^x - 8.
[tex]1 = {27} \times 27^{1 + x - 8} [/tex]
3) Use the product rule: x^a x^b = x^a+b.
[tex]1 = {27}^{1 + x - 8} [/tex]
4) Simplify 1 + x - 8 to x - 7.
[tex]1 = {27}^{x - 7} [/tex]
5) Use Definition of Common Logarithm: b^a = x if and only if logb (x) = a.
[tex] log_{27}1 = x - 7 [/tex]
6) Use Change of Base Rule.
[tex] \frac{ log_1 }{ log{27} } = x - 7[/tex]
7) Use rule of 1: log 1 = 0.
[tex] \frac{0}{ log_{27}} = x - 7[/tex]
8) Simplify 0/log_27 to 0.
[tex]0 = x - 7[/tex]
9) Add 7 to both sides.
[tex]7 = x[/tex]
10) Switch sides.
[tex]x = 7[/tex]
Therefor, the answer is x = 7.
I have a question that says " jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the whole book?" (I NEED HELP)
Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so [tex]\frac{3}{5}[/tex] will become [tex]\frac{5}{3}[/tex].
Now we do 75 times [tex]\frac{5}{3}[/tex]/
[tex]\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125[/tex]
So, there are 125 total pages in the book.

Write a simplified expression that represents the perimeter of an irregular quadrilateral with side lengths (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2).
Answer:
7 7/4 t - 1
Step-by-step explanation:
The perimeter of the quadrilateral is the sum of all the sides combined together
Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),
Taking the sum;
Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)
Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2
Collect like terms;
Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2
Perimeter = (9t-2t)/4 + 7t -1
Perimeter = 7/4 t + 7t - 1
Perimeter = 7 7/4 t - 1
