III.     B. Help in making people a valuable resource

Answer:

The number is -1.

Step-by-step explanation:

Set up an equation:

Variable n = number

8 × n + 4 = -4

Use PEMDAS

8n + 4 = -4

Isolate the variable:

8n = -8

n = -1

Check your work:

8 × -1 + 4 = -4

-8 + 4 = -4

-4 = -4

Correct!

Answer:

-1

Step-by-step explanation:

Write out the equation in numbers.

1. Eight times a number = 8x

2. Added to four = +4

3. Is -4 = =-4

4. Now put it together- 8x + 4 = -4

5. Subtract 4 from each side- 8x = -8

6. Divide both sides by 8- x = -1

Yana though of a number she multiplied it by 8 subtracted 4 divided the result by 2, and got 30. What number did Yana think of

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

From the question we are told that:

Thought of Number x

Multiplied it by 8

 [tex]x*8=8x[/tex]

Subtracted 4

 [tex]8x-4[/tex]

Divided the result by 2

Answer:

Center (3, -8), radius = [tex]\sqrt{39}[/tex]

Step-by-step explanation:

The Standard Form for the equation of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

The center is the point (h, k) and the radius is r.

Match up the given equation with the standard form.

[tex](x-h)^2=(x-3)^2 \rightarrow h=3\\(y-k)^2=(y+8)^2 \rightarrow k=-8[/tex]

That last bit can be tricky, k = -8, not 8.  Watch the signs!

Answer:

B.    m = [tex]\frac{3}{2}[/tex], y-int = 3

Step-by-step explanation:

To find the slope of the line, we need to plot two points

(2, 6) (-2, 0)

m = slope

Then use the Slope-Formula to Solve for the slope

m = [tex]\frac{y2-y1}{x2-x1}[/tex]        

m = [tex]\frac{0-6}{-2-2}[/tex]

m = [tex]\frac{-6}{-4}[/tex]

m = [tex]\frac{6}{4}[/tex]

m = [tex]\frac{3}{2}[/tex]

The Slope is [tex]\frac{3}{2}[/tex]

The y-intercept is 3 because the line is going 3 units upwards on y axis!

Equation: y = 3/2x + 3

Slope: 3/2

y-intercept: 3

Answer:

m = 3/2      int- 3

Step-by-step explanation:

The line goes up 3 and goes right 2. The line crosses the y-intercept at 3.

Answer:

250

Step-by-step explanation:

create a proportion based on 10 berries to every one orange:

let 'b' = # berries

10/1 = b/25

cross-multiply to get:

b = 10(25)

b = 250

Answer:

the y intercept is 4

and frm that point to another spot on the line you go DOWN one unit (negative)

and two units to positive (to the right)  thus the slope is - 1 (down) and 2 positive to the right

-1/2 = slope

y = -1/2 + 4

Effective % Off » 25%

Answer:

$28.5

Step-by-step explanation:

100% - 25% = 75% (so you don't have to add or subtract anything)

38 * .75 = 28.5

=$28.5

Given:

Two lines intersect each other.

Consider the below figure attached with this question.

To find:

The value of x.

Solution:

If two lines intersect each other then the vertically opposite angles are congruent and their measures are equal.

In the given figure, the measures of two vertically opposite angles are (2x+29)° and (9x-13)°.

[tex]2x+29=9x-13[/tex]

[tex]2x-9x=-29-13[/tex]

[tex]-7x=-42[/tex]

Divide both sides by -7.

[tex]x=\dfrac{-42}{-7}[/tex]

[tex]x=6[/tex]

Therefore, the value of x is 6.

Answer:

Area of circle bounded by a 135 ° arc is 4.71 m ²

Step-by-step explanation:

Radius of circle, r = 2 m

Angle of the circle , θ = 135 °

Area of circle bounded by a 135 ° arc.

Using Formula

Area of circle = θ/ 360 × π × r ²

substitute the values,

Area of circle = 135 /360 × 3.14 × ( 2 m) ²

solve it

Area = 27 / 72 × 3.14 × 4 m ²

Area = 27 / 18 × 3.14

Area = 1.5 × 3.14

Area = 4.71 m ²

Therefore, Area of circle bounded by a 135 ° arc is 4.71 m ²

Answer:

D,0,2,-2

Step-by-step explanation:

2x^5-3x^3-20x=0

x(2x^4-3x^2-20)=0

x=0

or 2x^4-3x^2-20=0

put x²=t

2t²-3t-20=0

-20×2=-40

8-5=3

8×-5=-40

2t²-(8-5)t-20=0

2t²-8t+5t-20=0

2t(t-4)+5(t-4)=0

(t-4)(2t+5)=0

t=4

x²=4

x=2,-2

t=-5/2

x²=-5/2

it gives imaginary  root. so real rational roots are 0,2,-2

Answer:

D

Step-by-step explanation:

1) Factorise x

x(2x^4-3x^2-20) = 0

a product is equal to 0 when at least one factor is equal to 0.

so a solution is

x = 0

we have now to solve

2x^4 - 3x^2 - 20 = 0

we can put

x^2 = y

and we have

2y^2 - 3y - 20 = 0

it is now an equation of second degree

Δ = 9 + 160 = 169

y1 = (3 + 13)/4 = 4

y2 = (3 - 13)/4 = -10/4 = -5/2

for the previous relationship we have

x^2 = 4

x = 2

x = -2

x^2 = -5/2

a square number can’t be negative, so this equation is impossible.

In conclusion we can say that the original equation has three solution:

0, -2, 2

Answer: x = -1, -7

Step-by-step explanation:

I used internet

Answer:

x = -1   or   x = -7

Step-by-step explanation:

x^2 + 8x + 7 = 0

x^2 + 8x + ____ = -7 + ____

To complete the square, we add the square of half of the x-term coefficient to both sides.

x-term coefficient: 8

half of it: 4

square it: 4^2 = 16

We add 16 to both sides.

x^2 + 8x + 16 = -7 + 16

(x + 4)^2 = 9

x + 4 = +/- sqrt(9)

x + 4 = 3   or   x + 4 = -3

x = -1   or   x = -7
