−5=−8−x What is x? Solve for x

Answers

Hello there!

-5 = -8 -x
First, we need to get x isolated (put on one side of the equation by itself), and then divide by -1 to get rid of the negative sign.
Add 8 to both sides.
-5 + 8 = 3
-8 + 8 = 0
You are left with:
-x = 3
Now, we must divide both sides by -1 to solve for x.
-x / -1 = x
3 / -1 = -3
You are now left with the following solution:
x = -3

14x-(6+7x)

(Simplify answer)

Answers

14x-(6+7x)
=14x-6-7x
=14x-7x-6
=(14x-7x)-6
=7x-6x

We can simplify an expression by distributing if needed and combing terms if needed.

In the expression 14x - 6 + 7x the terms 14x and 7x are like terms. Because they both have the same variable and are to the same power.

14x - 6 + 7x
21x - 6

So, 21x - 6 is the answer.

The weight of 10 identical samples of a substance is 0.01 pound what is the weight of 10,000 samples

Answers

We use ratios here.

For every 10 samples, the total weight is 0.01 lb.

We write
10 / 0.01.

We want to find the weight of 10,000 samples.

We write
10,000/?

These two ratios must equal each other.

(10 / 0.01) = (10,000 / ?)

If you know how to cross-multiply, then we can do that here.
0.01 * 10000 = 10 * ?
100 = 10 * ?

The unknown value is 10, which is your answer.

Answer:

The weight of 10,000 samples is:

10 pounds.

Step-by-step explanation:

It is given that:

The weight of 10 identical samples of a substance is 0.01 pound.

i.e. 10 samples= 0.01 pound.

Now we are asked to find the weight of 10,000 samples.

Since,

10 samples= 0.01 pound.

1000×10 samples= 1000×0.01 pounds

i.e.

10000 samples= 10 pounds.

Hence, the answer is: 10 pounds.

#SPJ2

an airplane is flying from montreal to vancouver. the wind is blowing from the west at 60km/h. the airplane flies at an airspeed of 750km/h and must stay on a heading of 65 degrees west of north. what heading should the pilot take to compensate for the wind? what is the speed of the airplane relative to the ground?

Answers

Refer to the diagram shown below.

In order for the airplane to maintain a heading of 65° west of north, it actually heads at (65° +x) west of north at a speed of 750 km/h, to compensate for the wind blowing from west t east at 60 km/h.

The actual speed of the airplane relative to the ground is V km/h.

From geometry, obtain the triangle shown.
The speed of 750 km/h is opposite an angle of 155°, and the unknown angle x is opposite the wind speed of 60 km/h.

From the Law of Sines, obtain
[tex] \frac{sin(x)}{60}= \frac{sin(155^{o}}{750} \\ sin(x)= (\frac{60}{750})sin(155^{o})=0.0338[/tex]
[tex]x=sin^{-1}0.0338=1.937^{o}[/tex]

The heading that the pilot should take is 65 + 1.937 = 66.94° west of north.

The third angle of the triangle is 180 - (155 + 1.937) = 23.063°.
Use the Law of Sines to calculate V.
[tex] \frac{V}{sin(23.063^{o})}= \frac{750}{sin(155^{o})} [/tex]
[tex]V=( \frac{sin(23.063)}{sin(155)} )750=695.21\,km/h[/tex]

Answer:
The pilot heads approximately 67° (nearest integer) west of north.
The speed of the airplane relative to ground is 695.2 km/h (nearest tenth)

HELP QUICK !!!!!! Give an example of an absolute value problem with no solution

Answers

Here is an example of an absolute value problem with no solution 3+ |x+4| =0

Examples in real life and physics provide contexts for understanding situations where a direct solution is not possible or applicable.

An absolute value problem with no solution is one where the absolute value expression is set to a negative number. Since the absolute value of any number represents its distance from zero on a number line, it can never be negative. Consequently, an equation like |x| = -3 has no solution because there is no real number x that, when taken as an absolute value, results in a negative number.

Real-world Example...

In everyday life, think of a scenario such as locking oneself out of an encrypted system without any means of retrieval. The problem can't be solved directly (as there is no way to bypass encryption), but one might approach the matter sideways by resetting the system entirely, which doesn't address the original issue of being locked out.

Physics Context

In physics, an example of a situation where there is a force and a displacement but no work is done is when the force is applied perpendicular to the direction of the displacement. Since work is defined as the dot product of force and displacement, when the angle between them is 90 degrees, this product and thus work is zero.

(0, –12), (–6, 0), (2, 0)

Answers

Answer:

x-intercepts are (-6,0 and (2,0)

First option is correct.

Step-by-step explanation:

The given equation is [tex]y=x^2+4x-12[/tex]

For x-intercept, y=f(x)=0. Thus, we have

[tex]0=x^2+4x-12[/tex]

We can split the middle term as 4x = 6x-2x

Thus, the equation becomes

[tex]x^2+6x-2x-12=0[/tex]

Now, we make group

[tex](x^2+6x)+(-2x-12)=0[/tex]

Take GCF from each of the group

[tex]x(x+6)-2(x+6)=0[/tex]

Factored out the common term

[tex](x+6)(x-2)=0[/tex]

Apply the zero product property,

[tex]x+6=0,x-2=0[/tex]

Solve for x

[tex]x-6,x=2[/tex]

Thus, x-intercepts are (-6,0 and (2,0)

First option is correct.
