Answer:

[tex]\left(x+5\right)^2- 33=0[/tex]

See explanation below for steps

Step-by-step explanation:

We are given the quadratic equation

[tex]x^2+10x-8 = 0[/tex]

and asked to rewrite it in the form
[tex]\left(x+a\right)^2=b[/tex]

Move 8 to the right side:
[tex]x^2+10x=8[/tex]

[tex]\mathrm{Rewrite\:in\:the\:form}\:x^2+2ax+a^2[/tex]
[tex]\mathrm{Solve\:for\:}a,\:2ax=10x:\quad a=5[/tex]

[tex]\mathrm{Add\:}a^2=5^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2+10x+5^2=8+5^2[/tex]

So we get the original equation as:
[tex]\left(x+5\right)^2=33[/tex]

which can be rewritten as
[tex]\left(x+5\right)^2- 33=0[/tex]

Here a = 5, b = -33

Answer:

∠ BAS = 122° , ∠ N = 89°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(2)

∠ BAS is an exterior angle of the triangle, then

19x + 8 = 6x + 11 + 75

19x + 8 = 6x + 86 ( subtract 6x from both sides )

13x + 8 = 86 ( subtract 8 from both sides )

13x = 78 ( divide both sides by 13 )

x = 6

Then

∠ BAS = 19x + 8 = 19(6) + 8 = 114 + 8 = 122°

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

(4)

11x + 31 is an exterior angle of the triangle , so

11x + 31 = 5x - 4 + 10x - 1

11x + 31 = 15x - 5 ( subtract 15x from both sides )

- 4x + 31 = - 5 ( subtract 31 from both sides )

- 4x = - 36 ( divide both sides by - 4 )

x = 9

Then

∠ N = 10x - 1 = 10(9) - 1 = 90 - 1 = 89°

The average  rate of change on the interval - 1≤ x ≤ 4 for the given equation is 7.4

What is Quadratic equation ?

Quadratic equation can be defined as the equation which is in the form of ax^2+bx+c = 0 .

Given to find the average rate of change on the interval -1<= x <= 4

for the equation y = x^2+4x+1

put x = -1 in the equation  y = x^2+4x+1

y(-1) = -1*-1 + 4(-1) + 1

= -1-4+1

= -4.

y(4) = 4*4 + 4*4 + 1

= 16 + 16 + 1

=33

average rate = y(-1) - y(4) / -1-4

= -4-33 / -5

= 37 / 5

= 7 . 4

Hence, The average  rate of change on the interval - 1≤ x ≤ 4 for the given equation is 7.4

Answer:

The number 25 is not a prime number

Answer: 20.15

Step-by-step explanation:

First, make the percentage into an actual number. So divide 65 by 100 (because percent is based off of 100) which gives you 0.65. Then multiply 0.65 by 31 which gives you 20.15. Have a good day ;)

Fairfax is 15.94 miles more in distance to Manchester than to Hillsboro

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the distance between Manchester and Newton be = 10.94 miles

Let the distance between Newton and Fairfax be = 13.57 miles

Let the distance between Fairfax and Hillsboro be = 8.57 miles

Now , the distance between Manchester and Fairfax = distance between Manchester and Newton + distance between Newton and Fairfax

Substituting the values in the equation , we get

The distance between Manchester and Fairfax = 10.94 + 13.57

The distance between Manchester and Fairfax = 24.51 miles

So , the difference between the distances A = distance between Manchester and Fairfax - distance between Fairfax and Hillsboro

Substituting the values in the equation , we get

The difference between the distances A = 24.51 - 8.57

The difference between the distances A = 15.94 miles

Hence , the distance is 15.94 miles

So, the slope of the given line is 2.

The slope of a line is a measure of the steepness of the line and is represented by the letter "m" in the equation of a line: y = mx + b. The slope is calculated by the ratio of the change in y to the change in x.

The equation of a line y = 2x - 10 is already in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope of the line is m = 2.

This means that for every unit increase in x, y will increase by 2 units. If we graph this line, we can see that it has a steepness of 2, which means it has a positive slope. A positive slope indicates that the line increases as we move to the right and a negative slope indicates that the line decreases as we move to the right.

The principal of interest 3415 naira, rate = 5% and time 4 yrs and 3 months​ is 4017.64 naira.

In the context of borrowing, principal refers to the initial sum of a loan; it can also refer to the balance still owed on a loan. For instance, the principal of a $50,000 mortgage is $50,000. If you pay off $30,000, the remaining $20,000 constitutes the principal balance.

The principal of a loan determines how much interest you will pay. When you pay a loan off each month, the amount first goes to pay off the interest that has accumulated; only then is the remaining amount applied to the principal. The only way to lower the monthly interest payment is to reduce the loan's principal.

The factors or multiples of the algebraic expression, x² - 36 are (x-6) and (x+6) .

Factorization of algebraic expressions is defined as the process of finding the factors of an expression which refers to finding two or more expressions whose product is equals to that expression. Some Identities which are used to Factorize Algebraic Expressions,

(a+b)² = a² + b² + 2ab

(a - b)² = a² + b² - 2ab

a² - b² = (a+b)(a -b) etc.

We need to factorise, p(x) = x² − 36.

The algebraic expression, p(x) can be factorised by using property, a² - b² = (a+b)(a-b). So, it can be written as x² - 6², comparing it with a² - b² , here a = x,

b = 6. Hence, (x² − 36) = (x+6)(x−6). Therefore, the required factors are (x+6)(x−6).

Answer:

x = 2

y = 5

Step-by-step explanation:

Brainly doesn't provide online graphing tools, so I will try to walk you through what to do.

First put both equations in slope-intercept form:

y + x = 7  →  y = -x + 7

3y - 6x = 3   →   3y = 6x + 3  →  y = 2x + 1

These are easy to graph now.  

For equation (1), place a point on the y-intercept (0,7), then draw a line with a slope of -1  (down one, over one, down one, over one, etc.).  The x-intercept is (7,0).

For equation (2), the y-intercept is point (0,1).  Draw a line with a slope of 2 (up 2, over 1, up 2, over 1, etc.)  The x-intercept is (-1/2, 0).

Where the 2 lines intersect is the solution.  They should intersect at point (2,5).

Using the percentage, the amount raised in the first three months is $840

How can I calculate the money raised in three months?

By the conclusion of the academic year, the Helping Hands Student Club hoped to have raised $3,000 for a project.

It has attained 28 percent of its objective after three months.

The following formula can be used to determine how much was raised within the first three months:

amount raised = 28% × 3000

amount raised = 28 / 100 × 3000

amount raised = 84000 / 100

Answer: The total clockwise moment of the weight of the diving board and the weight of the girl at about Point A can be calculated using the equation:

moment = force x distance

In this case, the force is the weight of the diving board (800 N) and the weight of the girl (600 N) and the distance is the distance from Point A to the support (2.5m).

So the total clockwise moment is:

moment = (800 N + 600 N) x 2.5 m = 1400 N x 2.5 m = 3500 Nm

The unit for moment is Newton-meter (Nm).

It's worth noting that in this problem, the clockwise moment is calculated by considering the force and the distance in the same direction, and the moment is positive, if the force is acting in a clockwise direction.
