find the output,y, when the input x is -7.

Answer:

B.

Step-by-step explanation:

Plug in the x-values for x in the answer choices. The result will be the y-value of the table.

For example,

A. 3(-1)^2+3(-1)-2 = -2

That is not the y-value for -1, so A is not the answer.

B. 3(-1)^2-3(-1)-2=4.

4 works here, but make sure to try all the numbers.

3(0)^2-3(0)-2 = -2

3(3)^2-3(3)-2 = 16

B is the answer because with each x-value you substitute in for x,  you get its corresponding y-value.

(-1,4) (0,-2) (3,16)

Answer:

triangle A because the measurements would be the same. If you add 30 + 112, you get 150. Triangles add to 180, so the missing angle of the first one is 30.

this means triangle A has the same measurements as ABC

Answer:

None of those is right

But if you have to put something then try A and B

Step-by-step explanation:

Here's the right answer for each equation

A. 100

B. 1000

C. 1000

D. 10000

E. 100

So if the question was to select each equation that the number 100 makes true.

Then the answers would have been A and E

Answer:

AB = √37

BC = 2√5

AC = √41

Type: SCALENE TRIANGLE

Step-by-step explanation:

Given the coordinates

A(1, –9), B(0, –3), C(–4, –5)

We are to find the length of each sides first. Using the formula for calculating the distance between two points, we will have;

For A(1, –9) and B(0, –3)

AB = √(-3+9)²+(0-1)²

AB = √6²+(-1)²

AB = √36+1

AB = √37

For coordinates B(0, –3) and C(–4, –5)

BC = √(-5+3)²+(-4-0)²

BC= √(-2)²+(-4)²

BC = √4+16

BC = √20

BC = 2√5

For coordinates  A(1, –9), C(–4, –5)

AC = √(-5+9)²+(-4-1)²

AC= √(4)²+(-5)²

AC = √16+25

AC = √41

Since the sides of the triangles are all different, hence the triangle is a SCALENE triangle

Answer:

Smaller number = 4

Larger number = 13

Step-by-step explanation:

Smaller number = x

Larger number = 4x - 3

Sum of the numbers = 17

x + 4x -3 =  17   {Combine like terms}

   5x - 3 = 17    {add 3 to boht sides}

        5x = 17 + 3

        5x = 20      {Divide both sides by 5}

          x = 20/5

         x = 4

      Larger number = 4x - 3

                               = 4*4 -3

                                = 16 - 3

                                = 13

Answer:

y = -2x+7

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope, c = y-intercept

1) find the slope using the given coordinates

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

i) (3,1)

x1=3

y1=1

ii) (7,-7)

x2=7

y2=-7

substitute the values into the formula

[tex]m = \frac{ - 7 - 1}{7 - 3} [/tex]

[tex]m = \frac{ - 8}{4} [/tex]

[tex]m = - 2[/tex]

so now half of the equation is complete as we have the the value of m. substitute the value of m into the slope formula.

[tex]y = - 2x + c[/tex]

2) find the value of c

to find the value of c, we must substitute either coordinate into the half equation. so, i choose the coordinate (3,1). if you substitute the coordinate (7,-7) , you will get the same value of c.

(3,1)

x = 3

y = 1

[tex]y = - 2x + c[/tex]

[tex]1 = - 2(3) + c[/tex]

[tex]1 = - 6 + c[/tex]

[tex]1 + 6 = c[/tex]

[tex]c = 7[/tex]

substitute the value of c into the half equation and that is your straight line equation

[tex]y = - 2x + 7[/tex]

Answer:

5 3/4yd²

Step-by-step explanation:

Area of the pen = length × width

Given

Length = 3 5/6 yds

Width = 1 1/2 yards

Area = 3 5/6 × 1 1/2

Area = 23/6 × 3/2

Area= 23/4

Area = 5 3/4yd²

Hence t required area is 5 3/4yd²

Answer:

40?

Step-by-step explanation:

10 x 10= 100

but this is perimeter so it would be 10 by 4 sides

10x4=40

Answer:

40

Step-by-step explanation:

A square has equal sides, area is length times height, meaning the square root of 100 is one side of the square. [tex]\sqrt{100}[/tex] = 10, because 10(10) = 100

Now one side is 10 meters, a square has 4 equals sides so:

10(4) = 40

Or u can do it the long way, 10 + 10 + 10 + 10  = 40

Answer:

80.219

Step-by-step explanation:

0.14 + 80.079 =

80.219

Fourteen hundredths + Eighty + Seventy-nine thousandths = 80,480.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Fourteen hundredths = 1,400

Eighty = 80

Seventy-nine thousandths = 79,000

Then the addition will be

⇒ 1400 + 80 + 79000

⇒ 80,480

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

Let the middle number be x.

(x - 1)(x)(x + 1) = 21,924

You can solve that equation, or you can use logic.

The 3 numbers are going to be close to the cubic root of 21,924.

cubic root of 21,924 = 27.988 or approx 28.

Try 27, 28, 29

27 * 28 * 29 = 21,924

Answer: 27

The smallest number of the three consecutive numbers is 27.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Let the consecutive numbers be (x - 1), x, and (x + 1)

x(x - 1)(x + 1) = 21,924

(x² - x)(x + 1) = 21,924

x³ + x² - x² - x = 21924

x³ - x = 21924

We can assume that the numbers will be near the cube root of 21924.

Now,

∛(21924) = 27.899

Now,

The numbers can be 27, 28, and 29.

27 x 28 x 29 = 21924

Thus,

The smallest number is 27.

Answer:

Y=X+3

Step-by-step explanation:

The equation represents a line that is parallel to x = 0 will be y = x.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that there is an equation that represents a line that is parallel to x = 0. The equation will be calculated as below:-

y = mx + c

y = x slope will be equal to 1.

Therefore, the equation represents a line that is parallel to x = 0 will be y = x.

Vertical asymptote at x= -6 and 6. The zero is 0

Step-by-step explanation:

20 blue fish and 50 total

9514 1404 393

Answer:

Step-by-step explanation:

1. The vertical asymptotes are where the denominator is zero.

  x² -36 = 0

  (x -6)(x +6) = 0   ⇒   x = 6 or x = -6 . . . vertical asymptotes

The horizontal asymptote is the function value when x is large. Since the numerator is lower degree than the denominator, the ratio becomes near 0 as x gets large. The horizontal asymptote is y = 0.

The function value is zero when the numerator is zero:

  6x = 0   ⇒   x = 0 . . . . the zero of the function

A function graph is attached, with vertical asymptotes and zero shown.

__

2. You can work this problem by considering the ratios.

If 60% of fish are red, then 40% are blue. The difference in numbers is 60% -40% = 20% of the total number of fish. That difference is 10 fish.

The number of blue fish is 40% of the total, which is 2×20% = 2×10 fish.

There are 20 blue fish.

Answer:

u may need a calculator

Step-by-step explanation:

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

Answer:

Step-by-step explanation:
