Step-by-step explanation:

1)  Simplify 2 /5y to 2y/5.

[tex]\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2[/tex]

2) simplify 1/5x to x/5.

[tex]\frac{2y}{5} +\frac{x}{5} -0.2y-6-2[/tex]

3) Collect like terms.

[tex](\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)[/tex]

4) Simplify.

The diameter of a circle is 15 m. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

Answers

Given that, the diameter of the circle 15 m. The circumference of a circle is 2πr. Then the circumference of the circle with the given diameter is 47.1  m.

What is circumference of a circle?

Circumference of a circle is also called its perimeter and it describes the overall area of the surrounding circular path. The distance round a circle is its circumference, but this cannot be used as a definition if, as in many elementary treatments, distance is defined in terms of straight lines.

In these conditions, the limit of the perimeters of inscribed regular polygons may be described as the circumference of a circle as the number of sides increases without constraint.  When describing abstract geometric forms as well as measuring real-world things, the term circumference is frequently used.

It is given that, the diameter of the circle = 15 m

radius r  = diameter/ 2 = 15 m/ 2 = 7.5 m

circumference of circle = 2 π r

                                       = 2 × 3.14 × 7.5 m

                                       = 47.1 m

What is the equation of the graph below?
А
y = 2(x + 4)2 – 2
B
y = (x – 4)2 – 2
C y = 2(x - 4)2 – 2
D
y = 2(x – 4)2 + 4

Answers

Answer:

f(x) = 1(x - 4)^2 - 2

Step-by-step explanation:

Recall that the vertex form of the equation of a parabola is

f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.

Looking carefully at the graph, we see that h must be 4 and k must be -2.

Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)

Saved $500 from his summer job so he would have spending money during the school year. He withdraws $12 from his account each week so a linear function models his plan. Mellissa made a similar plan. Compare the transactions

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Savings = \$500[/tex]

[tex]Withdrawal = \$12[/tex] weekly

Required

The question is incomplete as the linear function or table or graph of Melissa's plan is not given.

The available details can only be used to solve the function of the given individual

Let the number of weeks be w.

So: the amount left in w weeks is:

[tex]Amount = Savings - Withdrawal * w[/tex]

[tex]Amount = 500- 12* w[/tex]

[tex]Amount = 500- 12w[/tex]

Represent as a function

[tex]f(w)= 500- 12w[/tex]

To solve the amount left at the end of a certain week (say week 5), simply substitute 5 for w in [tex]f(w)= 500- 12w[/tex]

[tex]f(5) = 500 - 12 * 5[/tex]

[tex]f(5) = 440[/tex]

The red arcs mean those angles are the same.

When two angles are the same the corresponding sides are also the same.

5. X = 8

6. X = 11

7. 2x-16 = 8

Add 16 to both sides:

2x = 24

Divide both sides by 2:

X = 12

8. X + 19 = 8

Subtract 19 from both sides:

X = -11

the sum of the square of two consecutive positive integers is 85. Write a quadratic equation​

Answers

Answer:

2x^2 + 2x - 83 = 0

Step-by-step explanation:

Consecutive integers differ by 1

Let the first number be x

The next will be (x+1)

The sum of the squares of these two numbers is 85

so we have;

x^2 + (x + 1)^2 =85

= x^2 + x^2 + 2x + 2 = 85

2x^2 + 2x + 2-85 = 0

2x^2 + 2x - 83 = 0
