Hey there,

Solve the equation:

x = 4 ✅

3x - 4 = 8

>> Add 4 to both sides :

3x - 4 + 4 = 8 + 4

3x = 12

>> Divide both sides by 3 :

3x/3 = 12/3

Therefore, your answer is x = 4

Answer:

x = 4

Step-by-step explanation:

Given equation:

To determine the value of "x", we need to isolate the "x" variable and it's coefficient. This can be done by adding 4 to both sides of the equation.

The next step in determining the "x" variable is to isolate the coefficient from the "x" variable. This can be done by dividing 3 both sides of the equation.

Therefore, the solution (x) is 4.

The value of the missing variable x in the diagram is; 4

In mathematics, two triangles are said to be similar provided that they have the same ratio of corresponding sides and equal pair of corresponding angles.

Now, from the given image, we can see that DE bisects AC into 2 equal parts and by virtue of the concept of similar triangles, we can say that;

DE/BC = 1/2

We are given;

DE = x + 1

BC = 4x - 6

Thus;

(x + 1)/(4x - 6) = 1/2

Cross multiply to get;

2x + 2 = 4x - 6

4x - 2x = 6 + 2

2x = 8

x = 4

That value of x is the missing value required in conclusion.

Answer:

y = -1/2x - 2

Step-by-step explanation:

Slope Intercept form: y=mx+b

You need to find the slope and y-intercept.

(0,-2) is the y-intercept which is the point on the y-axis that is intersected by the linear equation which is our slope line.

Now, we need to find our slope.

*This line is a negative slope*

Starting at our y-intercept [ (0,-2) ] we need to go to a point where the line intersects.

The red dot on the coordinate plane clearly represents it.

(2,-3) is the red point in which we need to go down 1 and over 2 to get there.

So our slope should be -1 / 2

Lastly, write in slope-intercept form:
y = -1/2x - 2

Answer:

(34.15, 47.85)

Step-by-step explanation:

[tex]n = (\frac{z*stddev}{ME} )^{2}[/tex]

stddev = 11.9

z = invNorm(

area = (1 + confidence interval)/2

mean = 0

stddev = 1

)

= invNorm(

0.995

0

1

)

≈ 2.576

n = 20

square root both sides

[tex]\sqrt{20} = 2.576 * 11.9 / ME[/tex]

multiply both sides by ME, divide both sides by √20 to isolate ME
ME = 2.576 * 11.9/√20

≈ 6.85

interval = mean ± ME
= (41-6.85, 41+6.85)

= (34.15, 47.85)

Answer:

[tex]x=4y^2-24y+30[/tex]

[tex](x-4.5)^2+(y-2.5)^2=23[/tex]

Step-by-step explanation:

Standard form of a sideways parabola:  [tex]x=ay^2+by+c[/tex]

Given equation:

[tex]4y^2-x-24y+30=0[/tex]

Add x to both sides:

[tex]4y^2-24y+30=x[/tex]

[tex]\implies x=4y^2-24y+30[/tex]

--------------------------------------------------------------------------------------------

Standard form of circle equation

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where (a,b) is the center and r is the radius)

Given equation:

[tex]2x^2+2y^2-18x-10y+7=0[/tex]

Group like terms:

[tex]2x^2-18x+2y^2-10y+7=0[/tex]

Divide by 2:

[tex]x^2-9x+y^2-5y+3.5=0[/tex]

Factor by completing the square for each variable:

[tex](x-4.5)^2-20.25+(y-2.5)^2-6.25+3.5=0[/tex]

Rearrange into standard form:

[tex](x-4.5)^2+(y-2.5)^2=23[/tex]

Therefore, the circle has a center at (4.5, 2.5) and a radius of √23

to get the equation of any straight line, we simply need two points off of it, let's use the points in the picture below.

Answer:

31/55 * 111

Step-by-step explanation:

For all the other products, the number before the slash is greater than, or equal to the number after the slash. This means that the fraction is greater than or equal to 1 and thus a bigger product. For 31/55 however, the value is less than 1 (0.56) and thus, the actual product will be less than 111.

The question is an illustration of the laws of cosine, the length of the third side is 6.7 units

The measure of the third side is calculated using the following law of cosine

a^2 = b^2 + c^2 - 2bc * cos(A)

So, we have:

a^2 = 8^2 + 11^2 - 2 * 8 * 11 * cos(37)

Evaluate the expression

a^2 = 44.44

Take the square root of both sides

a = 6.7

Hence, the length of the third side is 6.7 units

I took the Test it is 72

Answer:

x would be equal to 1.1

Step-by-step explanation:

Step 1:  Determine the value of x

I assume that the equation looks like this:  16/x = 45/3

Therefore, using the cross multiply method we can do (16*3) = (x*45)

This will give us 48 = 45x

Then we divide both sides by 45 so we can isolate x by itself

45x/45 = 48/45

x = 1.0667

Then we round to the nearest tenth

x = 1.0667

x = 1.1

Answer: x would be equal to 1.1

Answer:

x = 16/15, or (to the nearest tenth) x = 1.1

Step-by-step explanation:

Note:  there must be an " = " sign between the two fractions:

 16         45

------- = -------

   x           3

Also note that 45/3 reduces to 15:      16/x = 15

Multiplying both sides by x yields 16 = 15x, so that x must be  x = 16/15 = 1.1

Answer:

b=8

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 =c^2  where a and b are the legs and c is the hypotenuse

6^2 + b^2 = 10^2

36+b^2 = 100

Subtract 36 from each side

b^2 = 100-36

b^2 = 64

Take the square root of each side

sqrt(b^2) = sqrt(64)

b = 8

Answer:

31

Step-by-step explanation:

The median is the number that we find in the middle of the data.

So if we have a sequence of {1,2,3}

Then 2 is the median

If we have a sequence of {1,2,3,4,5}

Then 3 is the median

We look in the middle of 28,30,30,30,30,31,31,31,31,31,31,31,31

and we find 31 in the middle.

Note:

If the middle is something with 2 terms in the middle like

1,2,3,4

Then the median is the average of the two middle terms which is
