Step-by-step explanation:

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically  stretched by a scale factor of 4.

Table for the corresponding points will be,

x               w(x)                  r(x)

0                0                  0×4 = 0

15              60               60×4 = 240

30             120             120×4 = 480

45             180             180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

   and r(x) = 4[w(x)]

   r(x) = 4(4x) = 16x

  r(x) = 16x

Step-by-step explanation:

3x - 2y = 19 ...1

Replace y = x-7 in ...1

3x - 2(x-7) = 19

3x - 2x + 14 = 19

x = 19 - 14

= 5

Replace x = 5 in y = x - 7

y = 5 - 7

= -2

Step-by-step explanation:

s + 90 = 120

s = 120 - 90

s = 30

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Where s is the amount to spend.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Mirna earned $120 babysitting during spring break.

She needs to save $90 for the German Club trip.

She wants to spend the remainder of the money shopping.

This means,

The remainder amount,

= 120 - 90

= $30

We can write an inequality as,

s ≤ 120 - 90

s ≤ 30

Where s is the amount of money to spend on shopping.

Thus,

The most simplified inequality form of the amount of money s to spend on shopping is

s ≤ 30

Answer:

x=-7

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(3x+9)=24

Step 1: Simplify both sides of the equation.

−2(3x+9)=24

(−2)(3x)+(−2)(9)=24(Distribute)

−6x+−18=24

−6x−18=24

Step 2: Add 18 to both sides.

−6x−18+18=24+18

−6x=42

Step 3: Divide both sides by -6.

−6x /−6

= 42 /−6

Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

Answer:

f(-3) = 2

f(-1) = 2

f(8) = 1

Step-by-step explanation:

Yep! For any function f(x), you find the y value corresponding the x value. For example, in this question, it asks us to find f(-3). Therefore, you go to the line, x = -3, and see where it intersect the function (the y value). Your answer would be the y value.

The value corresponding to f(-3) seems to be 2.

The value corresponding to f(-1) seems to be -2.

The value corresponding to f(8) seems to be 1.

Answer:

B. [tex] y = 65x [/tex]

Step-by-step explanation:

Equation showing a proportional relationship between two quantities, is usually written as [tex] y = kx [/tex]. Where,

y = output/dependent variable

x = input/independent variable

k = constant of proportionality that exists between each pair of values given.

In this case:

y = trees planted

x = time (weeks)

To find the constant of proportionality, k, use any given pair as (x, y). Let's use (10, 650).

Substitute y = 650 and x = 10 into [tex] y = kx [/tex], and solve for the value of k.

[tex] 650 = k(10) [/tex]

Divide both sides by 10

[tex] \frac{650}{10} = k [/tex]

[tex] 65 = k [/tex]

[tex] k = 65 [/tex]

Substitute k = 65 into [tex] y = kx [/tex] to generate the equation that shows the proportional relationship in the table:

[tex] y = 65x [/tex]

The value of x for the given triangle will be 111°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The sum of all angles inside a triangle is 180°

So,

47° + x° + 22° = 180°

x = 180° - 69° = 111°

Hence "The value of x for the given triangle will be 111°".
