Hi there! Given the equation below.

[tex] \large{r + \sqrt{x} = 9}[/tex]

First is to subtract both sides by r-term to isolate x-term.

[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

[tex] \large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }[/tex]

Alternative Solution

[tex] \large{x = {r}^{2} - 18r + 81}[/tex]

Answer:

She pays $1060 for the phone.

Step-by-step explanation:

Deposit = $100

She pays $80 each month for a year. $80 x 12 = $960. Then we need to add the deposit with the monthly instalments to find the total. $100 + $960 = $1060

Total:

$1060

P=2(l+w)  

A= wl

80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

you then would have to find 2 numbers that would add up to make 42.

When you try 16*2+5*2= 32+10= 42 cm as your perimeter.

16*5= 80 cm^2 as your area.

Answer:

x = [tex]\frac{83}{36}[/tex]

Step-by-step explanation:

Given

x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )

x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = [tex]\frac{83}{36}[/tex]

the value of the product when A=2 b-3 and C= -2 :

(4a-5b)*(3a+4b-2c)

Answer:

0.05223

Step-by-step explanation:

0.05723 is 0.05223 greater than 0.005.

A decimal number is one in which the whole number component and the fractional component are separated by a decimal point. The decimal point is the dot seen in decimal numbers. The decimal point is followed by digits that represent a number less than one.

As an illustration, consider the decimal value 17.48, where 17 is the entire integer and 48 is the decimal portion.

When one number exceeds another, the phrase "more than" is used. Even greater than is utilised to compare the two weights.

Take the difference

0.05723-0.005=0.05223

Hence, 0.05723 is 0.05223 greater than 0.005.

Answer:

12s - 16t

Step-by-step explanation:

2(3s + t) + 2(3s - 9t)

6s + 2t + 6s - 18t

12s + 2t - 18t

12s - 16t

Answer:Perimeter of the rectangle =(12s -16t)centimeters.

Step-by-step explanation:

The perimeter of a rectangle is given as 2(l+w)

Given that  width of the  rectangle=(3s+t)centimeters. and

Length of the  rectangle=(3s-9t)centimeters.

Solving we have

Perimeter= 2(l+w)

Perimeter=2(3s+t +3s-9t)

Perimeter=2(3s+3s -9t+t)

Perimeter=2(6s-8t)

Perimeter=(12s -16t)centimeters.

Answer:

y = x²+8x+7

Step-by-step explanation:

according to the table, we get the point :

(-4, -9) as the vertex and (0, 7) as y-intercept

y = ax²+bx+c

=> the symetry axis :

x = -b/2a = -4

b=-4×2a = 8a

let a=1, => b = 8(1) = 8

y-intercept = (0, c) =(0, 7) => c =7

so, the equation might be :

y = x²+8x+7

Step-by-step explanation:

g(x) = x^2

g(3) = 3^2 =9

g(-3) = (-3)^2 = 9

g(3) + g(-3) = 9+9 =18

Answer:

18

Step-by-step explanation:

g ( x) = x²

g ( 3 ) = ( 3 )² = 9

g ( -3 ) = ( - 3 )²

g ( - 3 ) = 9

g( 3 ) + g ( -3 ) = 9 + 9 = 18

Answer:

4y - 3x = -25

Step-by-step explanation:

The equation of a line in point-slope form is expressed as

y - y0 = m(x - x0)

(x0, y0) is the point

m is the slope

Given

(x0, y0) = (3, -4)

Also given the equation;

8x + 6y = 15

Rewrite in standard form;

6y = -8x+15

y = -8/6 x + 15/6

y = -4/3 x + 5/2

Slope m = -4/3

Since the required line is perpendicular to the given line =,

Slope = -1/(-4/3) = 3/4

Substitute into the formula;

y - (-4) = 3/4(x-3)

y + 4 = 3/4(x-3)

4(y+4) = 3(x-3)

4y + 16 = 3x - 9

4y - 3x = -9-16

4y - 3x = -25

This gives the required equation

The opposite of a function is its inverse

The ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)

From the function, we have the following ordered pairs

(x,y) = (4,-2), (-2,-2), (-1,-2)

The inverse of a function (x,y) is (y,x).

So, we have:

(y,x) = (-2,4), (-2,-2), (-2,-1)

Hence, the ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)
