Answer:

x = 0

Step-by-step explanation:

Line segment UV and line segment VW together form line segment UW.

UV + VW = UW

(5 + x) + (6) = (2x + 11)

5 + x + 6 = 2x + 11

x + 11 = 2x + 11

x + 11 - 11 = 2x + 11 - 11

x = 2x

x - x = 2x - x

0 = x

You can also verify the result by substituting x with our result 0.

5 + x + 6 = 2x + 11

5 + (0) + 6 = 2(0) + 11

11 + 0 = 0 + 11

11 = 11

Left side of the equation is the same as the right side of the equation, therefore the result x = 0 is correct.

GIVING A BRAINLIST PLZZ ASAP

Jobisdone [24]

Answer:

(b) Mr. Sánchez's class earned more money.

(a) $\displaystyle [42, 37] → [j, p]$

Step-by-step explanation:

{79 = p + j

{118,17 = 1,65p + 1,36j

−25⁄34[118,17 = 1,65p + 1,36j]

{79 = p + j

{−86 121⁄136 = −1 29⁄136p - j >> New Equation

__________________________

$\displaystyle \frac{-7\frac{121}{136}}{-\frac{29}{136}} = \frac{-\frac{29}{136}p}{-\frac{29}{136}}$

$\displaystyle 37 = p$ [Plug this back into both equations above to get the j-value of 42]; $\displaystyle 42 = j$

The next step is to plug the solution into the BOTTOM EQUATION to calculate the total money earned for each class:

Sánchez's class

$\displaystyle 61,05 = [37][1,65]$

Altogether, thirty-seven fruit pies cost $61,05.

Kelly's class

$\displaystyle 57,12 = [42][1,36]$

Altogether, forty-two bottles of fruit juice cost $57,12.

* Based on the calculation, it is perfectly clear that Mr. Sánchez's class earned more money by $3,93:

$\displaystyle 3,93 = -57,12 + 61,05$

I am delighted to assist you anytime my friend!

Please help me do question 21, 22 and 23. I am in 6th grade.

Pachacha [2.7K]

Question 21: 24 minutes

$\frac{3}{\frac{3}{2} } = \frac{x}{12}$

x = $(\frac{3}{\frac{3}{2} })(12)$

x = 24

Question 22: 20 centimeters

x = one side of the square

x² = 25

x = 5

4x = perimeter

4(5) = perimeter

20 = perimeter

Question 23: 17 sides

Hexagon = 6 sides

Octagon = 8 sides

Triangle = 3 sides

Total amount of sides = 6 + 8 + 3

Total amount of sides = 17

Consider the inverse function. Which conclusions can be drawn about f(x) = x2 + 2? Select three options. f(x) has a limited rang

PolarNik [594]

Answer:

f(x) has a limited range

f(x) has a maximum at the point (0, 2)

f(x) has a y-intercept at the point (0, 2).

Step-by-step explanation:

Given the function;

f(x) = x^2+2

The domain is the value of the input variables for which the function will exist. According to the expression given, the function exists on all real values of x. The same goes with range which deals with the output values. It also exists on all real values from 2 and above.

Hence f(x) have a limited range (since values less than 2 are not included compare to domain that exists on all real values) and does not have a restricted domain.

For the x intercept, x intercept occur at y = 0

substitute y = 0 into the function and get y

if y = f(x)

y = x^2+2

0 = x^2 + 2

x^2 = -2

x = 2i

Hence f(x) does not have an x-intercept of (2, 0)

For the y intercept, y intercept occur at x = 0

substitute x = 0 into the function and get y

if y = f(x)

y = x^2+2

y = 0^2 + 2

y = 2

Hence f(x) has a y-intercept at point (0, 2)

f(x) is at maximum if d(fx))/dx = 0

d(fx))/dx = 2x

since d(fx))/dx = 0

0 = 2x

x = 0

substitute x = 0 into the function

f(x) = x^2 + 2

y = 0^2+2

y = 2

Hence f(x) has a maximum at the point (0, 2)
