Solve for b -5/8b=10

1 answer:

4 0

-5/8b b=10

The new equation would look like this because we multiplied 8xb. 8 x b = 80

-5/80

Now if you divide -5 by 80 you get -0.0625

So -0.0625 is your answer

What is the equation of this line? y = -4× y = 4× y = - 1/4× y = 1/4×

sashaice [31]

The answer is the third choice: y=-1/4x.

We find this by remembering that slop is rise over run. Since the rise is -1 and the run is for we can make it -1/4 as the slope, which is next to the x term. Since the y intercept is at the origin we do not have a b term from the formula y=Mx+b.

Factor the following trinomial. (Hint: Solve the equations first.) x²-2x-2

Alex_Xolod [135]

Answer:

$(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2} -2x-2=0$

$a=1\\b=-2\\c=-2$

substitute in the formula

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}$

$x=\frac{2(+/-)\sqrt{12}} {2}$

$x=\frac{2(+/-)2\sqrt{3}} {2}$

$x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}$

$x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}$

therefore

$x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))$

A volley is 1800 cm long and 900 cm wide it is divided into two equal halves for each of the team. What is the area one team occ

madam [21]

Answer:

First of all, you'd divide 1800 by 2, which equals 900; then you divide 900 by 2, which is 450. Add those teo together and you'd get 1350, which is the answer.

Please let me know if this is wrong and I'll check it over
