What Values Of B And C Make ADEF AWVU?U46-9vD5b+36F12b-343cEwb =

Answers

Answer 1

Answer:

b = 10, c = 9

Step-by-step explanation:

For the triangles to be congruent by the HL postulate, then

UW = DF ( hypotenuse are congruent ), that is

12b - 34 = 5b + 36 ( subtract 5b from both sides )

7b  0 34 = 36 ( add 34 to both sides )

7b = 70 ( divide both sides by 7 )

b = 10

and

UV = EF ( legs are congruent )

4c - 9 = 3c ( subtract 3c from both sides )

c - 9 = 0 ( add 9 to both sides )

c = 9

Answers

Answer: 8

Step-by-step explanation: Given:

Total money Jervane can spend = $20.

Cost of a coffee = $3.

Cost of a donut = $2.

To find: Maximum number of donuts Jervane can buy.

Solution:

Let the number of donuts she can buy be .

She wants to spend no more than $20 in total.

So,

As the number of donuts can only be a natural number.

Hence, the maximum number of donuts that Jervane can buy are 8.

A function is defined as follows:

IN THE SCREENSHOT

For which x-values is f(x) = 4? Select all that apply.

-2
1
2
13

Answers

Answer:

f(x) = 4 for the values 2 and -2.

Step-by-step explanation:

Given

y = { x+6      x < -2

       x²        -2 ≤ x ≤ 3

      3x+1      x > 3 }

To determine

For which x-values is f(x) = 4

It is clear that:

The portion of the function f(x) = x² has the interval  -2 ≤ x ≤ 3

Now, if we enter x = 2 or x = -2 in f(x) = x² from the interval -2 ≤ x ≤ 3 we get the output 4.

i.e.

at x = -2,

f(-2) = (-2)² = 4

also

at x = 2,

f(2) = (2)² = 4

Therefore, f(x) = 4 for the values 2 and -2.

In the equation a and b represent the price per night for a room in hotel a and hotel b respectively w week s

Answers

Answer:

A = $80

Step-by-step explanation:

A = 240 - 20w

B = 320 - 30w

Equate both equations

240 - 20w = 320 - 30w

Collect like terms

240 - 320 = -30w + 20w

-80 = -10w

Divide both sides by -10

w = -80/-10

w = 8

Substitute w into equation A

A = 240 - 20w

= 240 - 20(8)

= 240 - 160

= 80

A = $80

if a system of linear equation has an infinite number of solutions, what do you know about the graph of the system?

a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed

Answers

Answer:

c. the lines are the same

Step-by-step explanation:

A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.

Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.

Hence, the correct answer would be option (C).
