11 more than x is less than. 3 (please)

Answers

Answer:

(11+x)-3

Step-by-step explanation:

11 more than x is another way of saying 11+x

And "less than 3" means subtracting 3 from the terms

So if you put that together it would be

(11+x) -3

The triangles are similar. Solve for x. Hint - draw the triangles separately.

Answers

Answer:

The answer is 18

Step-by-step explanation:

All you have to do is look at the length the left side of the triangle and see what you have to divide the larger number by to get the smaller number.

Then you have to divide the number on the bottom by the number that you had to divide the larger number by the side by.

Patty buys a new car and gets it appraised every few years. After owning the car for 3 years, its value is $15,000. After owning the car for 5 years, its value is $9,000.

If Patty gets her car appraised after owning it for 6 years, what will the car's value be in this indirect variation situation?

A. $7,500
B. $2,500
C. $6,000
D. $4,000

Answers

Answer:

c) 6000

Step-by-step explanation:

the car's value would be $6000 because in two years the car decrased by $6000. Divide that by 2, and get $3000. That's how much it decreases in one year. $9000-$3000=$6000

btw I can't help it the car's original value was $24,000

What is the value of x?
Enter your answer in the box
39
X=
102°

Answers

Answer:

x=39

Step-by-step explanation:

The interior angles add up to 180 degrees so you do 39+102, which is 141. Then you subtract 141 from 180 and then you get 39 degrees.

Correct answer:

39

Explanation:

The total value of the angles of the triangle is 180 so subtract 102 and 39 from 180.
180-39-102 = 39 :))

Answer:

Write a rule for g described by the transformation of the graph of f...

Answers

Answer:

[tex]g(x) = 4-4\sqrt{x}[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4\sqrt{x}+1[/tex]

1. 5 units down translation

2. Reflection in the x-axis

Required

Determine the resulting function g

1. 5 units down translation

This is defined by the rule:

A down translation is:

[tex]f'(x) = f(x) - b[/tex]

Where b is the number of units.

So, we have:

[tex]f'(x) = 4\sqrt{x} + 1 - 5[/tex]

[tex]f'(x) = 4\sqrt{x} -4[/tex]

2. Reflection in the x-axis

For a function f(x),

When reflected over the x-axis, it becomes -f(x)

So:

[tex]g(x) = -f(x)[/tex]

[tex]g(x) = -(4\sqrt{x} - 4)[/tex]

[tex]g(x) = -4\sqrt{x} +4[/tex]

[tex]g(x) = 4-4\sqrt{x}[/tex]

HELP ME PLEASE The roots of a quadratic equation can be found using the graph what are the roots of these equations?

Answers

Answer:
(-1,4)
Explanation:
On the left if you estimate it brings to a -1 and on the right if you count boxes bring to a 4
Hope its correct

Answer:

the roots of this quadratic expression are: x = -1 and x = 4

Step-by-step explanation:

You need to find at which x-values the graph crosses the x-axis (this is when y = 0, and therefore the roots of the quadratic equation represented via the graph).

In our case notice that the graph crosses the x-axis at the points:

x = -1 (on the left), and x = 4  (on the right)

Therefore the roots of this quadratic expression are: x = -1 and x = 4.

Answers

Answer:

The answer will be the following :

Step-by-step explanation:

Let's solve for x.

3x−2y=46x

Step 1: Add -46x to both sides.

3x−2y+−46x=46x+−46x

−43x−2y=0

Step 2: Add 2y to both sides.

−43x−2y+2y=0+2y

−43x=2y

Step 3: Divide both sides by -43.

−43x

−43

=

Use the linear combination method to solve the system of equations. Explain each step of your solution.
2x-3y=13
2x+4y=-8

Answers

Step-by-step explanation:

Equation 1: 2x - 3y = 13

Equation 2: 2x + 4y = -8

Subtract Equation 1 from Equation 2:

2x + 4y = -8

- (2x - 3y = 13)

=> 7y = -21, y = -3.

Then 2x - 3(-3) = 13, 2x + 9 = 13, x = 2.

The solutions are x = 2 and y = -3.
