What is the value of x is the solution to the equation -8(x + 3) = -10x - 5?

Answers

Answer 1

Answer:

x = 19/2

Step-by-step explanation:

1) Distribute

-8x-24=-10x-5

2) Add 24 to both sides

-8x-24+24=-10x-5+24

3) Simplify

- Add the numbers

-8x = -10x - 5 + 24

- Add the numbers

-8x = -10x+19

4) Add 10x to both sides

-8x+10x=-10x+19+10x

5) Simplify

- Combine like terms

2x = -10x+19+10x

-Combine like terms

2x=19

6) Divide both sides by the same factor

2x/2 = 19/2

7) Simplify

- Cancel terms that are in both the numerator and denominator

x = 19/2

In circle G with m \angle FGH= 86m∠FGH=86 and FG=16FG=16 units, find the length of arc FH. Round to the nearest hundredth.

Answers

The length of arc FH in the circle 8.37 units.

What is circle?

In mathematics, a circle is a closed two-dimensional shape that consists of all the points in a plane that are a fixed distance (called the radius) from a given point (called the center). Circles are used in many areas of mathematics and science, including geometry, trigonometry, and physics. They have important applications in areas such as engineering, architecture, and computer graphics.

Here,

To find the length of arc FH, we first need to find the measure of angle FGH in degrees. Since the sum of angles in a triangle is 180 degrees, we can use the fact that angles FGH and FGF are supplementary to find:

m∠FGF = 180 - m∠FGH = 180 - 86 = 94 degrees

Since FGF is an inscribed angle that intercepts arc FH, the measure of arc FH is twice the measure of angle FGF. So we have:

m(arc FH) = 2 × m∠FGF = 2 × 94 = 188 degrees

To find the length of arc FH, we need to know the circumference of circle G. Since we know that FG = 16 units, we can use this to find the radius of the circle:

r = FG/2 = 16/2 = 8 units

The circumference of the circle is then:

C = 2πr = 2π(8) = 16π

To find the length of arc FH, we need to find the fraction of the circumference that arc FH represents, and then multiply this by the total circumference. Since the measure of arc FH is 188 degrees out of a total of 360 degrees in the circle, we have:

Length of arc FH = (188/360) × C

Substituting the value of C, we get:

Length of arc FH = (188/360) × 16π

Simplifying and rounding to the nearest hundredth, we get:

Length of arc FH ≈ 8.37 units

ɪ ʀ x ᴅ ꜱ ᴄ ᴇ ɴ ᴛ

Answer:

e = 10

Step-by-step explanation:

In this question we are provided with an equation that is 9e + 4 = -5e + 14 + 13e . And we are asked to find the value of e .

Solution : -

[tex] \longrightarrow \qquad \: 9e + 4 = {-5e} + 14 + { 13e}[/tex]

Step 1 : As there are like terms in right side . So we are solving them and get :

[tex] \longrightarrow \qquad \: 9e + 4 = 14 + 8e[/tex]

Step 2 : Subtracting 4 on both sides :

[tex] \longrightarrow \qquad \: 9e + \cancel{4 }- \cancel{4 }= 14 + 8e - 4[/tex]

Now , cancelling 4 with -4 and subtracting 4 from 14 :

[tex]\longrightarrow \qquad \: 9e = 10 + 8e[/tex]

Step 3 : Subtracting 8e on both sides :

[tex] \longrightarrow \qquad \: {9e } - {8e } =10 + \cancel{ 8e} - \cancel{ 8e}[/tex]

On further calculating , we get :

[tex]\longrightarrow \qquad \: \underline{\boxed{\bold{ \frak{{e = 10}}}}}[/tex]

Therefore , value of e is equal to 10.

Verifying : -

We are verifying our answer by substituting value of e in given equation. So ,

9e + 4 = -5e + 14 + 13e

9 (10) + 4 = -5 (10) + 14 + 13 (10)

90 + 4 = -50 + 14 + 130

94 = -50 + 144

94 = 94

L.H.S = R.H.S

Hence, Verified.

Therefore, our value for e is correct .

The heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q=20930 joules (J) when m=1kg and T=5 degrees C. Find m when Q=8372 J and T=10 degrees C

Answers

Answer:

m = 0.2 kg.

Step-by-step explanation:

Joint variation:

Q = kmT where k is a constant.

Subsituting the given values:

20930 = k*1*5

k = 20930 / 5 = 4186.

So the relation is:

Q = 4186mT

When Q = 8372 and T = 10:

8372 = 4186 * m * 10

m = 8372 / (4186*10)

m = 0.2 kg.

Answer:

Below!

Step-by-step explanation:

The provided equation is in standard form. To convert it to slope intercept form, we need to have the y-variable isolated (as much as possible) on the L.H.S. Let's start the process by subtracting 6x both sides. This will isolate the y-variable and the cooeficient of the y-variable.

⇒ 6x + 2y = 12⇒ 6x - 6x + 2y = 12 - 6x⇒ 2y = 12 - 6x

To further isolate the "y" variable, let's divide 2 both sides. This will isolate the cooeficient of the y-variable. Once the cooeficient of the y-variable is fully isolated, we simply need to simplify the R.H.S (If needed). Then, the equation obtained is in slope intercept form.

⇒ 2y/2 = 12/2 - 6x/2⇒ y = 12/2 - 6x/2

LIkewise, since the R.H.S can be simplified, let's simplify the R.H.S. The equation we obtained for now is in slope intercept form, but the simplified equation would help us to graph the line.

⇒ y = 12/2 - 6x/2⇒ y = 6 - 3x

When we look at the slope intercept form formula (y = mx + b), we can see that "6" and "3x" needs to be switched.

⇒ y = -3x + 6                                                    (Slope intercept form)

Finally, lets plot the line on the graph. To plot the line on the graph, we need to determine the x-intercept and the y-intercept.

y-intercept: (0, 6)

The x-intercept is the R.H.S of the equation we obtained. Keep in mind that the "y" variable will be 0.

⇒ -3x + 6 = 0

Once we found the solution, we will determine two points of the line and lastly, we will plot the line on the graph.

⇒ -3x + 6 - 6 = 0 - 6⇒ -3x = -6⇒ -3x/-3 = -6/-3⇒ x = 2

Thus, we obtained the following points:

x-intercept = 2 ⇒ Point obtained: (2, 0)y-intercept = 6 ⇒ Point obtained: (0, 6)

→ Then, plot these points on the graph. Remember, x coordinate first.

→ Finally, we can draw a line through these points.

And we are done!
