0.4 = -9.8 -y + 2.8y

Answers

Answer 1

Answer: [tex]y=5.666667[/tex]   or   [tex]y=5 \frac{6}{9}[/tex] in fraction

Step-by-step explanation:

1. Simplify  -9.8-y+2.8y  to  -9.8+1.8y

0.4=-9.8+1.8y0.4=−9.8+1.8y

2. Regroup terms

0.4=1.8y-9.8

3. Add 9.8 to both sides.

0.4+9.8=1.8y

4. Simplify  0.4+9.8  to  10.2

10.2=1.8y

5. Divide both sides by 1.8

[tex]\frac{10.2}{1.8} =y\\[/tex]

6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667

5.666667 = [tex]y[/tex]

7. Switch sides.

[tex]y=5.666667[/tex]

Hope this helps and can you please mark me brainliest because I just need 1 more brainliest to become expert:)

cbjsabcakvscds

The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.

What is the inverse function?

Let the function f is given as

y = m(x + a) + c

Then the inverse function of the function f will be given by the swapping of x with y and y with x.

The function is given below.

f(x) = x⁴ + 7

The inverse function of f(x) will be

x = [g(x)]⁴ + 7

[g(x)]⁴ = x - 7

[tex]\rm g(x) = \sqrt[4]{x - 7}[/tex]

The function is valid for x ≥ 7.

The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.

Answers

Answer:

  an infinite number of ways

Step-by-step explanation:

The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.

So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."

__

One way to describe it is this:

The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.

__

* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.

Answer:

h = 18( I might be wrong though)

Step-by-step explanation:

If BE and ED are perpendicular, that means this angle is supplementary.

BEF = 3h-12

FED = 2h - 23

BEF + FED = 90

3h-12 + 2h - 23 = 90

5h - 35 = 90

5h = 90

h = 18 degrees

31

The expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

An expression that has a value of 31

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

A) 3√25 + 7-5

= 3(5) + 7 - 5

= 15 + 7 - 5

= 17

B) (3√25) +7-5

= (3x5) +7-5

= 15 +7-5

= 17

C) 3√25+ (7-5)

= 3x5 +2

= 17

D) 3(√25 + 7) - 5

= 3(5+7) - 5

= 36 - 5

= 31

Thus, the expression 3(√25 + 7) - 5 has a value of 31 after applying arithmetic operation option (D) 3(√25 + 7) - 5 is correct.
