What is the solution set for the equation 8=x^2-2 x

Answer:

m=0.7404, b=3.9117m=0.7404,b=3.9117

y=0.7404x+3.9117y=0.7404x+3.9117

x=18x=18

y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Residual

16-17.2389= -1.238916−17.2389=−1.2389

-

The residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Now, We know that;

Equation is,

y = bx + a

Where,

b = (xy) - (x) (y) / x² - y²

Here, We have;

x = 12.5

y = 13.17

(xy) = 211.17

Hence, We get;

b = (211.17 - 164.625) / (219.17 - 156.25)

b = 0.74

So, We get;

y = bx + a

13.17 = 0.74 × 12.5 + a

a = 3.92

So,

y = 0.74x + 3.92

y = 0.74 × 18 + 3.92

y = 17.24

Thus, the residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

Answer:

The length of BE is 5 units.

Step-by-step explanation:

ABCD is rectangle

AC is a diagonal and BD is a diagonal too.

Diagonals of rectangle are equal and bisect each other perpendicularly.

So, AE = BE

AE = 1/2 × AC

= 1/2 × 10

= 5

BE = 5

Hence the length of BE is 5 units.

Answer:

[tex]a=2;b=5;c=-20[/tex]

Step-by-step explanation:

Given:

Number tree is given.

Given hint: To get a number in the square multiply the numbers in the two circles connected to it.

[tex]a*(-4)=-8\\a=-\frac{8}{-4} \\a=2[/tex]

[tex]a*b=10\\2*b=10\\b=\frac{10}{2} \\b=5[/tex]

[tex]b*(-4)=c\\5*(-4)=c\\c=-20[/tex]

Therefore, final answers are:

[tex]a=2;b=5;c=-20[/tex]

Probabilities are used to determine the chances of events

The value of t is 16

The number of bricks is given as t

Let the number of red bricks be x.

So, the number of blue bricks would be t - x

So, the probability values are:

[tex]\frac{x -1}{t - 1} = \frac 13[/tex] --- when the both bricks are red

[tex]\frac{x}{t - 1} = \frac 25[/tex] --- when only the second brick is red

Divide both equations

[tex]\frac{x -1}{t - 1} \div \frac{x}{t - 1} = \frac 13 \div \frac 25[/tex]

Divide

[tex]\frac{x -1}{x} = \frac 13 \div \frac 25[/tex]

This gives

[tex]\frac{x -1}{x} = \frac 13 *\frac 52[/tex]

Evaluate the product

[tex]\frac{x -1}{x} = \frac 56[/tex]

Cross multiply

[tex]6x - 6 = 5x[/tex]

Collect like terms

[tex]6x - 5x = 6[/tex]

[tex]x = 6[/tex]

Recall that:

[tex]\frac{x -1}{t - 1} = \frac 13[/tex]

So, we have:

[tex]\frac{6 -1}{t - 1} = \frac 13[/tex]

[tex]\frac{5}{t - 1} = \frac 13[/tex]

Cross multiply

[tex]t -1 =15[/tex]

Add 1 to both sides

[tex]t = 16[/tex]

Hence, the value of t is 16

The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.

A linear equation is in the form:

y = mx + b

where m is the rate of change (slope) and b is the y intercept.

Given the line is x - 8y = 16:

8y = x - 16

y = x/8 - 2

The slope of the line is 1/8, the slope of the line perpendicular is -8. Hence, since it passes through (2 -2):

y - (-2) = -8(x - 2)

y = -8x + 14

The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.

When two lines intersect each other then the vertically opposite angles are equal. Then the correct option is A.

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

The diagram is shown.

We know that when two lines intersect each other then the vertically opposite angles are equal.

Then

x = 52° because they are vertically opposite angles.

Thus, the correct option is A.
