(-8) + (+12) what is the answer to this can someone please write it out clearly?​

Answer and work down below. Let me know if you have any questions

Answer:

b

Step-by-step explanation:

because its math and it makes sense

Answer:

Substitute the 2nd and 3rd equations for x and y into the first equation.

Use the distributive property to simplify terms

Combine like terms to get 12z = -24

Solve for z = -2

Solve for x and Y by substituting z into 2nd and 3rd equations

Step-by-step explanation:

2x - y + 3z = -12

x = 3 + 2z

y = -6 - 5z

Substitute;

2(3 + 2z) - (-6 - 5z) + 3z = -12

Distribute;

6 + 4z + 6 + 5z + 3z = -12

Combine like terms;

12 + 12z = -12

Subtract 12 from both sides;

12z = -24

Divide by 12 to get z;

z = -2

Substitute z into x and y to get their values;

x = 3 + 2(-2)

x = 3 - 4

x = -1

y = -6 - 5(-2)

y = -6 + 10

y = 4

Now to check;

2x - y + 3z = -12

2(-1) - (4) + 3(-2) = -12

-2 - 4 - 6 = -12

-12 = -12

CORRECT!

4, Does not round

the second 4, rounds to 5 because of the 8,

then The 9 would round and be 30

if its a decimal then it would be 30.0

if not then i think it would be 30,500 or 29,500 if we were to stop at the 9 and not round it

Hello Person!!

Here's the correct answer choice! ^^

There are three steps.

The steps are at 8 from 0 to 1, at 12 from 1 to 2, and at 16 from 2 to 3.

Closed circles are on the left side of each step, and open circles are on the right.

Step-by-step explanation:

Because,

Given that y=4 is the equation

This is on the interval [0,3]

Since y=4 for all x, we get

when x=0, y=4. when x =1, y=4 and so on.

In other words, if we connect (0,4),(1,4)...(3,4) we get a horizontal line parallel to x axis passing through the above points from x=0 to x=3

ii) x=2 on [0,3]

Here x is constant but  y varies from 0 to 3

When y takes values from 0 to 3, x =2 always

Hence a vertical line placed parallel to y axis a a disance of 2 units from  y axis.

P.S Tell me if this is wrong....

Answer:2.5

Step-by-step explanation:

The correct answer is B. 2.3.

For us to know the equivalent decimals of a fraction, you have to use the numerator as the dividend, and the denominator will be your divisor.

The equation will be:

2 + ( 1 / 3 )

2 + (0.33333333)

= 2.333333

If you'll have it rounded off, you'll get the answer 2.3.

Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in

Circumference of circle= 2πr so, 2×5×π= 31.4 in

Answer:

Step-by-step explanation

1. area of a circle = πr²

2. circumference of a circle = 2πr

where diameter = 10 in.

                radius = 10 / 2 = 5 in

1. area of a circle = π(5)²

                            = 78.5 in²

2. circumference of a circle = 2πr

                                              = 2π(5)

                                             = 31.4 in

Answer:

v in (-oo:+oo)

1.13/64 = (11/8)*v // - (11/8)*v

1.13/64-((11/8)*v) = 0

(-11/8)*v+1.13/64 = 0

0.01765625-11/8*v = 0 // - 0.01765625

-11/8*v = -0.01765625 // : -11/8

v = -0.01765625/(-11/8)

v = 0.01284091

v = 0.01284091

Step-by-step explanation:

1 13/64 = 11/8x

Rewrite the left side as an improper fraction:

77/64 = 11/8x

Divide both sides by 11/8

77/11 = 7

64/8 = 8

X = 7/8

Answer:

y=2x^2+16x+30

divide 2 out: y=2(x^2+8x+15)

Then factor: y=2(x+5)(x+3)

Answer:

9.006

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since the figure is a right angled triangle we can use trigonometric ratios to find measure of ∠A.

To find ∠A we use sine

sin ∅ = opposite / hypotenuse

From the question

the opposite is 13

the hypotenuse is 15

So we have

[tex] \sin(∠A) = \frac{13}{15} \\∠A = \sin ^{ - 1} ( \frac{13}{15} ) \\ ∠A = 60.0735651...[/tex]

We have the final answer as

∠A = 60.07°

Hope this helps you

Step-by-step explanation:

Hey there!

Here;

As the figure shown is a Right angled triangle. Taking refrence angle as angle A, we get,

p= 13

h = 15

In ratio of sin there is p and h, So using sin ratio.

[tex] \sin( \alpha ) = \frac{p}{h} [/tex]

Put all values.

[tex] \sin( \alpha ) = \frac{13}{15} [/tex]

Simplify it.

[tex] \sin( \alpha ) = 0.86666666[/tex]

[tex] \alpha = { \sin}^{ - 1} (0.8666666)[/tex]

[tex] \alpha = 60.0732°[/tex]

Therefore the measure of angle A is 60°.
