B/5>-1<br> Solve the inequality. Graph and check the solution.

Usimov [2.4K]

Answer:

b>-5

Step-by-step explanation:

$\frac{b}{5} > - 1$

Multiply by 5 to isolate b.

$b > - 5$

If you graph this on a line, it would be a hollow point facing the right, since it's any number greater than five, not including 5.

If you put any number greater than -5, you'll output greater than - 1.

$\bf \cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\
\cfrac{smaller}{larger}\qquad \cfrac{3}{4}=\cfrac{\sqrt{13}}{\sqrt{a}}\implies \cfrac{3}{4}=\sqrt{\cfrac{13}{a}}\implies \left( \cfrac{3}{4} \right)^2=\cfrac{13}{a}
\\\\\\
\cfrac{3^2}{4^2}=\cfrac{13}{a}\implies \cfrac{9}{16}=\cfrac{13}{a}\implies a=\cfrac{16\cdot 3}{9}$

Help Asap please).The total cost after tax to repair Deborah's computer is represented by 0.08 (50h) +50h, where h represents th

Svet_ta [14]

Answer:

0.08(50h)

Step-by-step explanation:

$0.08 (50h) +50h \\ = \frac{8}{100} (50h) + 50h \\ = 8\%(50h) + 50h \\$

Since, it took 50h to repair the computer so, 0.08(50h) represents the amount of tax Deborah has to pay. Which is 8% of 50h.

Simplify. 19x - 24x <br><br> What is the answer

Zepler [3.9K]

Answer:

x=0

Step-by-step explanation:

Simplifying

19x + -24x = 0

Combine like terms: 19x + -24x = -5x

-5x = 0

Solving

-5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '-5'.

x = 0

Simplifying

x = 0
