Answer:

$\boxed{\sf{b=4.5}}$

Step-by-step explanation:

To find the value of variable, you have to isolate the term of b from one side of the equation.

First, you subtract by 1.5 from both sides.

→ b+1.5-1.5=6-1.5

Solve.

Subtract the numbers from left to right.

⇒ 6-1.5=4.5

⇒ b=4.5

Therefore, the correct answer is b=4.5.

I hope this helps you! Let me know if my answer is wrong or not.

What are the solutions to x^2 + 8x + 7 = 0

Oksana_A [137]

So to solve this you need to reverse factor this problem

x^2 + 8x + 7 = 0

The common formula is this for factoring ax^2 + bx + c

Now you have to think what multplties to "c" and adds up to "b".

So in this case it's 7 x 1 = 7 and 7 + 1 = 8

So you set it up like this

(x + 7)(x + 1) = 0

So now you can check the factors by multiplying them together and see if it gets your original equation which is does.

So finally to get the answers you need to set each parenthesis to 0 and solve for x.

x + 7 = 0

x + 1 = 0

and we get x = -1 and - 7

You can also plug these two answers back into your original equation to see if it equals 0.

Find the limit as h goes to 0 of the quotient of the quantity 5 times the square of the quantity x plus h, minus 2 minus the qua

umka21 [38]

Expand
$\lim_{h \to 0} \frac{5(x^2+2hx+h^2)-2)-5x^2+2}{h}$

$\lim_{h \to 0} \frac{5x^2+10hx+5h^2-2-5x^2+2}{h}$

$\lim_{h \to 0} \frac{10hx+5h^2}{h}$

$\lim_{h \to 0} 10x+5h$
say h=0 so
10x

PLS HELP If |7 − 6y| > 30, whats the possible value of y?

Arte-miy333 [17]

Answer:

y<−23/6 or y> 37/6

Step-by-step explanation:

Solve Absolute Value.

|−6y+7|>30

We know either−6y+7>30or−6y+7<−30

−6y+7>30(Possibility 1)

−6y+7−7>30−7(Subtract 7 from both sides)

−6y>23

−6y /−6 > 23/−6

(Divide both sides by -6)

y<−23/6

−6y+7<−30(Possibility 2)

−6y+7−7<−30−7(Subtract 7 from both sides)

−6y<−37

−6y/−6< −37/−6

(Divide both sides by -6)

y> 37/6

Therefore the answer is

y<−23/6 or y> 37/6

I hope this helped you.
