Step-by-step explanation:

[tex] = \sqrt{x} .4 \sqrt{x} [/tex]

[tex] = {x}^{ \frac{1}{2} } \times 4 {x}^{ \frac{1}{2} } [/tex]

[tex] = 4 {x}^{ \frac{1}{2} + \frac{1}{2} } [/tex]

[tex] = 4 {x}^{ \frac{2}{2} } [/tex]

[tex] = 4 {x}^{1} [/tex]

[tex] = 4x[/tex]

Hello there.

To answer this question, we need to remember some properties about the vertex of quadratic functions.

Let [tex]f(x)=ax^2+bx+c,~a\neq0[/tex]. Its vertex can be found on the coordinates [tex](x_v,~y_v)[/tex] such that [tex]x_v=-\dfrac{b}{2a}[/tex] and [tex]y_v=-\dfrac{b^2}{4a}+c[/tex], in which [tex]y_v=f(x_v)[/tex].

Using the coefficients given by the question, we get that:

[tex]x_v=-\dfrac{8}{2\cdot(-1)}\\\\\\ x_v=-\dfrac{8}{-2}\\\\\\ x_v=4[/tex]

Thus, we have:

[tex]y=f(x_v)=f(4)[/tex]

So the statement is true, because the [tex]x[/tex] coordinate of the vertex of the function is equal to [tex]4.~~\checkmark[/tex]

unfortunatly i need the inequality to graph it

Step-by-step explanation:

Answer:

-3/4

Step-by-step explanation:

Step-by-step explanation:

Realize that:

speed = distance / time and thus

time = distance / speed

Then the whole journey of 40/60 hours is the sum of (let's call them t1 and t2)

cycling: t1 = 2/y hours

running: t2 = 4/(y-4) hours

so we must simplify t1+t2=40 minutes (a.k.a. 4/6 hours):

2/y + 4/(y-4) = 4/6

let's multiply the first term by (y-4)/(y-4) and the second term by (y/y):

[tex]\frac{2(y-4)}{y(y-4)} + \frac{4y}{y(y-4)} = \frac46[/tex]

since they now share a common denominator:

[tex]\frac{2(y-4) + 4y}{y(y-4)} = \frac46[/tex]

[tex]\frac{6y-8}{y(y-4)} = \frac46[/tex]

cross-products:

[tex]6 (6y-8) = 4y(y-4)[/tex]

further simplification:

[tex]36y - 48 = 4y^2 - 16y[/tex]

[tex]4y^2 - 52y + 48 = 0[/tex]

[tex]y^2 - 13y + 12 = 0[/tex]

Step-by-step explanation:

6(x + 4) = 20

6x + 24 = 20

6x = 20 - 24

6x = -4

x = -4/6

x = -2/3

Answer:

⅔

Step-by-step explanation:

6(x + 4) = 20

(6 . x) + (6 . 4) = 20

6x + 24 = 20

6x = 20 - 24

6x = (-4)

x = (-4)/6

x = - ⅔

Answer:

m<h=59º

Step-by-step explanation:

126=6x-1+17+5x

126=11x+16

126-16=11x

120-10=11x

110=11x

10=x

6(10)-1=59

Answer:

m<H = 59°

Step-by-step explanation:

Use the theorem on the measure of an exterior angle of a triangle.

5x + 17 + 6x - 1 = 126

11x + 16 = 126

11x = 110

x = 10

m<H = 6x - 1

m<H = 6(10) - 1

m<H = 60 - 1

m<H = 59°

The solution is A = 10

The value of the equation A = a + 10 , when a = 7 is A = 10

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

A = a + 3   be equation (1)

when a = 7

Substitute the value of a = 7 in the equation , we get

A = 7 + 3

On simplifying the equation , we get

The value of A = 10

Therefore , the value of A is 10

Hence , the equation is A = 10

I hope you can follow the formula and solution.

Answer:

6m-27

Step-by-step explanation:

The equivalent expression of 9(4/3m- 5 - 2/3m + 2) is 6m/3 - 27.

The correct option is C.

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given;

The expression 9(4/3m- 5 - 2/3m + 2).

To find the equivalent expression:

Simplifying,

9(4/3m- 3 - 2/3m)

= 9(4m/3 - 2m/3 -3)

= 9{(4m-2m)/3 -3}

= 9 {2m/3 - 3}

= 6m/3 - 27.

Therefore, 6m/3 - 27 is the equivalent expression.

Answer:

x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°

Step-by-step explanation:

Given the quadrilateral in which the sum of its four angles is 360°.

We can establish the following formula to find the value of x, and determine the measures of each angle:

x° + 2x° + 3x° + 4x° = 360°

Combine like terms:

10x° = 360°

Divide both sides by 10 to solve for x:

[tex]\mathsf{\frac{10x^{\circ}}{10}\:=\: \frac{360^{\circ}}{10}}[/tex]

x = 36°

Substitute the value of x into each unknown angle measures:

x = 36°

2x° = 2(36)° = 72°

3x° = 3(36)° = 108°

4x° = 4(36)° = 144°

Verify whether the sum of the previously unknown angle measures equal 360°:

x° + 2x° + 3x° + 4x° = 360°

36° + 72° + 108° + 144° = 360°

360° = 360° (True statement).

Therefore, the following are the angle measures of the given quadrilateral: x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°

Answer:

The absolute value of any number (positive or negative) is always positive.

h+8=15

Subtract 8 from both sides.

h=7

:)

Answer:

7

Step-by-step explanation:

absolute value means the distance from zero.

the absolute value of -8 is 8 because it is 8 units away from 0.

thus, the equation can be written as h+8=15.

h=7 because 15-8=7

Answer:

x = 5

Step-by-step explanation:

For A to be parallel to B

the alternate exterior angles must be equal

13x - 8 = 9x + 12

Subtract 9x from both sides

4x - 8 = 12

add 8 to both sides

4x = 20

Divide both sides by 4

Because X=5, the equation is literally just asking 5x5=10. So, following the order of operations, I would do 5x5 first which equals 25 plus 10. Since 25+10=35.  The answer is 35. Hope this helps! :p

If Ally is given three different sums of the same sequence to calculate, and she completes the three problems in order C) The sums increase in value because even though you subtract 7 from each term you are still increasing the positive number that is being multiplied so they will increase.

The sums will not decrease in value because there is no subtraction.  They will not increase in value because of multiplication or addition.  The sums will not decrease in value because of the subtraction of 7 from each answer.

Thus, the sums will increase in value because of the increasing positive number that is being multiplied.

The mystery divisor to the question based on the information given is 18.

Dividing the first dividend 4 by the unknown divisor x and getting the first number 2 in the quotient and when the quotient 2 is multiplied by the divisor gives 36, so definitely, 4 cannot be used

Using 40 as the dividend, 40 divided by the divisor x gives 2 as the first quotient. And the first quotient 2 multiplied by the divisor x gives 36.

And to interpret this, 2x=36

Dividing through by 2x=36

x = 36/2

x = 18

So, the divisor is 18

Answer:

Step-by-step explanation:

Given :  Statement about proportional relationships  

To Find : Which statement is False

Solution:

proportional relationships

y ∝ x

=> y = kx    

Comparing with line line of equation

y = mx + c

m = k  , c = 0

TRUE

at x = 0 , y = 0

Hence graph of a proportional relationship must pass through (0, 0).

TRUE

y = kx  

=> y/x = k  hence

Each point (or pair) in a proportional relationship must share the same ratio.

Each point (or pair) in a proportional relationship must share the same difference.
