Answer:

B for the first one and it is correct.

x - 4 = - 7 for the second one and it is correct.

Step-by-step explanation:

Left hand panel

2x + 5 > 9 Subtract 5 from both sides.

2x + 5 - 5 > 9 - 5 Collect like terms

2x > 4 Divide by 2

x > 4/2

x > 2

Right Hand Panel

5x ≤ 30 Divide by 5

5x/5 ≤ 30/ 5

x ≤ 6

Your answer is Correct. (B)

Right hand panel

It's not the normal procedure. Usually when you have an absolute value the next step would be

x - 4 = 7 and you add four to both sides. The question is very poorly constructed and it is meant to fool you, but it didn't. You got this one right as well. Both correct.

WORTH 50 POINTS | Which is equivalent to 8/12 = x/9

kaheart [24]

$\\ \sf\longmapsto \dfrac{8}{12}=\dfrac{x}{9}$

$\\ \sf\longmapsto 12x=8(9)$

$\\ \sf\longmapsto 12x=72$

$\\ \sf\longmapsto x=\dfrac{72}{12}$

$\\ \sf\longmapsto x=6$

A bank quotes an interest rate as 0.06341 annual effective yield. What interest rate, compounded monthly, will provide that

Leviafan [203]

9514 1404 393

Answer:

0.06164

Step-by-step explanation:

The effective annual rate obtained by compounding nominal annual rate r monthly is ...

eff rate = (1 +r/12)^12 -1

Then the value of r is ...

r = 12×((eff rate) +1)^(1/12) -1)

For the given effective rate, that is ...

r = 12×(1.06341^(1/12) -1) ≈ 0.06164 . . . . nominal annual interest rate

What is the following sum 3b^2

densk [106]

The given expression is $3b^2*(\sqrt[3]{54a}) + 3*(\sqrt[3]{2ab^6})$

This can be simplified as :

= $3*b^2*(\sqrt[3]{27 *2*a}) + 3*(\sqrt[3]{2*a*b^6})$

We know that: $\sqrt[3]{27} = 3$

Similarly we also can simplify: $\sqrt[3]{b^6} = b^2$

So our expression will look like this:

= $3*3*b^2*(\sqrt[3]{2a}) + 3*b^2*(\sqrt[3]{2a})$

= $9b^2*(\sqrt[3]{2a}) + 3b^2*(\sqrt[3]{2a})$

= $\sqrt[3]{2a}*(9b^2 + 3b^2)$

= $\sqrt[3]{2a}*(12b^2)$

This can also be written as:

$12b^2(\sqrt[3]{2a})$

So the Answer is Option B
