im very confused of this question i need help

Answer:

Step-by-step explanation:

Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.

So (x+1) and (x-5) are root for the parabola.

y = (x+1)*(x-5)

That is the quadratic equation for Question B.

Back to A, the x-coordinate of vertex of this parabola is at x=2.

This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

Answer:

16 inches

Step-by-step explanation:

1 foot is equivalent to 12 inches so the puppy will grow 16 more inches which is equal to 28 inches.

Answer:

40

Step-by-step explanation:

In word problems, the word "of" usually means multiply.  Thus, for example, 10% of $50 is $5.  This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply:    (1/10)(50) = 5

So, we often see equations like:

    R = (1/2)D        meaning R is 50% of D, or R is half of D

Let x = the number we want to find

This problem says:

 "12 is 30%       of    what number?"

  12 = (30/100) *        x

12 = (3/10)x

(10/3)12 = x             [multiply both sides by (10/3)]

    40 = x        

Checking (very important):      

 Is   12 = (3/10)(40)    ?

       12 = (3)(4)    ?

       12 = 12     ? yes

Answer:

40

Step-by-step explanation:

Let x = unknown number

30% = 30/100 = 0.3

If 12 is 30% of x, then

   30% of x is 12

⇒ 0.3x = 12

⇒ x = 12 ÷ 0.3

⇒ x = 40

Or, you can divide 12 by 3 to get 10% and then multiply this by 10 to get 100%:

12 ÷ 3 = 4 (so 4 is 10%)

4 × 10 = 40 (which is 100%)

Answer:

I'm not sure how I can show you because you have to plot the points, not give a straight answer but I'll give you an idea.

Step-by-step explanation:

POINT 1: For the first point you are going to find 4 on the X axis and go up by 3. Plot your point there

POINT 2: Find the number 2 on the X axis and go up by 6

BTW keep in mind that the X axis is the the horizontal line that divides the coordinate plane half. If you folllow my intrustions for the first 2 points, you'll get an idea of how to grph the 3rd point!

Hope this helps!

Answer:

(ab + cd + ac - bd)(ab + cd - ac + bd)

Step-by-step explanation:

(ab + cd)² - (ac - bd)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = ab + cd and b = ac - bd , then

= (ab + cd + ac - bd)(ab + cd - (ac - bd))

= (ab + cd + ac - bd)(ab + cd - ac + bd)

Answer:

$1,500

Step-by-step explanation:

Shannon just borrowed $6,000 and charged her for 4% for 2 years. So you will divide 6,000 / 4 which gives you $1,500.

Range of a function is the extent to which any function may be varied. The range of the given function y= -3sin(x)-4 is [-7,-1].

The range of a function is the extent to which any function may be varied.

We know that the general range of the function of sin(x) is between [-1,1].

-1 ≤ sin(x) ≤ 1. . . . . . . . . .(A)

As our required function is y = -3sin(x) - 4

Now, in order to get this function, we will multiply each side in Equation (A) by -3, therefore,

-3 ≤ -3 sin(x) ≤ 3

Further, subtract from 4 from each side of the equation.

-7 ≥ -3sin(x)-4 ≥ -1

Hence, the range of the given function y= -3sin(x)-4 is [-7,-1].

The equation y = 3x - 5 is an illustration of a linear equation

The slope is 3, and the y-intercept is -5

The equation of the table is given as:

y = 3x - 5

When x = -1, we have:

y = 3(-1) - 5 = -8

When x = 0, we have:

y = 3(0) - 5 = -5

When x = 1, we have:

y = 3(1) - 5 = -2

So, the complete table is:

x     y

-1    -8

0      -5

1       -2

A linear equation is represented as:

y = mx + b

Where:

m represents the slope and b represents the y-intercept.

By comparison, we have:

m = 3, and b = -5

Hence, the slope is 3, and the y-intercept is -5

Answer:

2 : 4 : 1

Step-by-step explanation:

First take common factors by factorization.

56 = 14 x 4 = 28 x 2

112 = 14 x 8 = 28 x 4

28 = 14 x 2 = 28 x 1

Remove the 28 common factor.

Therefore,

56 : 112 : 28

= 2 : 4 : 1

Answer:

The answer is 16x-4x+1, give me brainliest answer

Answer:

–16(x2 – 3x – 4)

first we have to distribuite

-16x^2+48x+64

then we have to look for a number that goes into all of these which is -16

x^2-3x-4

then multiply the first by the last

-4x^2

then we have to find a two number that adds to make -3 and multiples to make -4x2

now lets list the factors

2*2

4*1

then lets just plug in

(x^2+x)(-4x-4)

now we have to factor out

x(x+1)-4(x+1)

-16(x-4)(x+1)

Answer:

(4,5)

Step-by-step explanation:

5 units right means the line x so we do 9-5 and we get 4.

Down 4 units means the y line so we do 9-4 and we get 5.

X goes 1st and y goes second so it is (4,5)

y = 3x + 2 = 3 * x + 2

point (10 ; 32) on the line ?

so here we can read : x = 10 and y = 32

if x = 10

then y has to be = 3 * 10 + 2 = 30 + 2 = 32

so yes - on the line

same reasoning for the rest

The ordered pairs which does not lie on the graph of the function are (8,13).

Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.

The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.

We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.

First ordered pair is (10,32)

32=3*10+2

32=30+2

32=32

It lies on graph.

Second ordered pair is (8,13)

12=3*8+2

12=24+2

12≠26

So it does not lie on graph of function y=3x+2.

Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).
