Answer:

  f(x) = {-x for x < 2; 2x-3 for x ≥ 2}

Step-by-step explanation:

The blue line extending to the left has a slope of -1 and a y-intercept of 0. Its equation is y = -x. That part of the definition of f(x) is applicable for values of x less than 2. (The open dot at (2, -2) tells you that point is not included.)

The red line extending to the right has a slope = rise/run = 2/1 = 2. The y-intercept can be found by extending the line to the y-axis, or from the computation ...

  b = y -mx

  b = 1 -2(2) = -3 . . . . . for the point (x, y) = (2, 1)

Then the slope-intercept equation for the red line is ...

  y = 2x -3

That part of the definition of f(x) is applicable for values of x ≥ 2. The solid dot tells you the point (2, 1) is included.

Putting these parts together, we get ...

  [tex]f(x)=\left\{\begin{array}{cc}-x&\text{if $x<2$}\\2x-3&\text{if $x\ge2$}\end{array}\right.[/tex]

Answer:

  120

Step-by-step explanation:

The dimension across the front in terms of cubes is ...

  5/3 cm = 5×(1/3 cm) = 5 cubes

The front-to-back dimension in terms of cubes is ...

  4/3 cm = 4×(1/3 cm) = 4 cubes

The height in terms of cubes is ...

  2 cm = 6×(1/3 cm) = 6 cubes

Then the volume in terms of cubes is ...

  V = LWH = 5×4×6 = 120 cubes

It will take 120 cubes to fill the prism.

Answer: 4/18

Step-by-step explanation:

The ratio 4:18 can be written as the decimal 0.22222222, so the value in the numerator is 4.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

Xavier writes a ratio out of 18 as the decimal 0.22222222.

Let's suppose the x out of 18 can be written as 0.22222222

x/18 = 0.22222222

x = 3.999999 ≈ 4

It means 4/18 can be written as 0.22222222

Thus, the ratio 4:18 can be written as the decimal 0.22222222, so the value in the numerator is 4.

Answer: soo

(4x^3+5x^2-3x-6)-(4x-5)

the answer is 4-^3+5x^2-7x-1

Step-by-step explanation:

Answer:

y = -1/2x + 2

Step-by-step explanation:

If you are talking about a linear equation then b=2

The slope is y2 - y1 / x2 - x1 so 2-0/0-4 = 2/-4 = -1/2

So put it all together in y = mx + b so y = -1/2x + 2

A) 72 in²

B) From the bottom right corner of the shaded square, draw a line either straight down or to the right.

C) 56 in²

Step-by-step explanation:

A) 8x9=72 in²

B) From the bottom right corner of the shaded square, draw a line either straight down or to the right.

C) The shaded area is 4x4=16, so you need to subtract that from the 72.

72-16=56 in²

Step-by-step explanation:

"Triples in size" means the growth factor is 3, so we expect to see that as the base of the exponent. That growth factor applies to a period of 6 minutes, or 1/10 hours. The number of 6-minute intervals in t hours is 10t, so we expect to see that as the exponent. The appropriate model could be written ...

Answer:

A. The interest cost $94.12 more than the electricity.

Step-by-step explanation:

2.97 x (10 years- 52 weeks in a year= 520) = 1544.40

P= PV x i / 1- (1+i)^-n

PV= 2879

I= .1389/12

N= 84 (7 years x 12)

53.78 x 84 = 4517.52

4517.52 - 2879 = 1638.52

1638.52 - 1544.40 = 94.12

A function assigns the value of each element of one set to the other specific element of another set. The correct graph is B.

A function assigns the value of each element of one set to the other specific element of another set.

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

The graph that represents the function can be chosen by substituting the values and checking the function.

Hence, the correct graph is B.

Answer:

angle 3x = 78°

angle opposite (4x + 30) = 226°

Step-by-step explanation:

It has 6 sides, so:

total interior angles sum = (180° x 6) - 360° = 720°

720° = 90° + 3x + 90° + 118° + (360° - (4x + 30°)) + 118°

combine like terms:

720° = 3x + 416° + (360° - 4x - 30°)

720° = -x + 746°

x = 26°

[tex]\Huge\boxed{C.61}[/tex]

Step-by-step explanation:

Hello There!

Remember this is the triangle angle rule:

The angles of a triangle MUST have a sum of 180

That being said we can find the missing angle by subtracting the given angles ( 87 and 32 in this case) from 180

so missing angle = 180 - 87 - 32

180 - 87 = 93

93 - 32 = 61

so we can conclude that the answer is c

Answer:

y = -1/2x - 5

Step-by-step explanation:

To solve this (and questions like it), use the formula for the equation of a line:

y=mx+c, where y and x are any given co-ordinates, m is the slope, and c is the y-intercept.

Since we know that the slope is -1/2, we can plug this into our equation to replace m:

y=mx+c

y=-1/2x+c

To find c, we plug in our co-ordinate (4,-7), so that c is the only unknown, and we can solve for it:

y=-1/2x+c

-7=-1/2(4)+c

-7=-2+c

c=-5

Now that we know c, we can finish off our equation:

y = -1/2x + c

y = -1/2x - 5
