1 point 5. Mariah drew a model to match the equation below. 2/1/6 =12 What model best represents her equation? ​

Answer:

f(x) = 3 - 4x^2

Step-by-step explanation:

Quadratic Equation form:   f(x) = ax² + bx + c

Quadratic function has a x (variable) with and exponent of 2.

They also leave a curve line on a coordinate plane. As you can see on the picture. ↓

Answer:

x+9

Step-by-step explanation:

4x³+12x²-72x

=4x(x²+3x-18)

=4x[x²+6x-3x-18]

=4x[x(x+6)-3(x+6)]

=4x(x+6)(x-3)

Answer:

11/13

Step-by-step explanation:

3/13, 5/13, 7/13, 9/13, 11/13

3/13

3/13 + 2/13 = 5/13

5/13 + 2/13 = 7/13

7/13 + 2/13 = 9/13

9/13 + 2/13 = 11/13

Answer: 187 kilogram

Step-by-step explanation:

Let the kilogram of dates be represented by x.

Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:

= 1/10 × x = 17

0.1x = 17

x = 17/0.1

x = 170 kilogram

Date = 170 kilogram.

Cocoa powder = 17 kilogram

The total kilogram of date and cocoa powder used will be:

= 170 + 17

= 187 kilogram

Answer:

330.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 11%/100 = 0.11 per year,

then, solving our equation

I = 1500 × 0.11 × 2 = 330

I = $ 330.00

The simple interest accumulated

on a principal of $ 1,500.00

at a rate of 11% per year

for 2 years is $ 330.00.

Answer:

Answer:

9/5

Step-by-step explanation:

What I do is look at the bottom number and add that to the top number how ever many time the whole number is.

The mixed number to the equation would be 9/5

Answer:

I'd say D, if I'm wrong please let me know. but I'm 100% sure it's D

Answer:

There are 9 girls in the class and 17 boys in the class

Step-by-step explanation:

Set up a system of equations where b is the number of boys and g is the number of girls

b + g = 26

b = g + 8

Solve by substitution by substituting g + 8 as b into the top equation

b + g = 26

(g + 8) + g = 26

2g + 8 = 26

2g = 18

g = 9

So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:

9 + 8

= 17

So, there are 17 boys.

There are 9 girls in the class and 17 boys in the class.

What is your question?

Step-by-step explanation:

[tex](x + 1)(x - 6)(x + 7)[/tex]

[tex] {x}^{2} - 6x + x - 6(x + 7)[/tex]

[tex] {x}^{3} + 7x - 6 {x}^{2} - 42x + {x}^{2} + 7x - 42[/tex]

[tex] {x}^{3} - 5x {}^{2} - 35x - 42[/tex]

Answer:

The slope is m= 4 and the y intercept is b= 9

Step-by-step explanation:

The slope is found by using change in y over change in x, or rise over run. From the table, this means, how much does y change for every time x goes up. As you can see, every time x increases by one, y increases by 4. So that´s your slope. The y intercept is when the line crosses the y axis, where x=0. Because you already know the slope, and that when x is one, y is 13, all you have to do is to know that going backwards by one for x means going backwards by 4 for y, and 13-4 is 9.

Answer:

2/8

Step-by-step explanation:

Since both have the same denominator its just subtraction. If you have 3 pieces of pie and eat 1, you have 2 left.

3-1=2

Then just add the denominator back on the bottom!

Reminder: This only works if the denominator is the same.

Answer:

14

Step-by-step explanation:

1. Distribute

2(y + 3) + 2(4 - y)

2 + 6 + 2(4 − )

2. Rearange terms

2y + 6 + 2(4 - y)

2 + 6 + 2(- + 4)

3. Distribute

2y + 6 + 2(-y - 4)

2y + 6 - 2y + 8

4. Add numbers

2y + 6 - 2y + 8

2y + 14 - 2y

5. Combine like terms

2y + 14 - 2y

14

6. Solution

14

can i be brainiest...

Answer:

the answer is 14y

Step-by-step explanation:

this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.

Answer:

B - ( 1, 3 )  D - ( 1, -2 )

Step-by-step explanation:

Answer:

x = 144

Step-by-step explanation:

3/4x + 24 = x - 12

3/4x - x = -12 - 24

3/4x - 4/4x = -36

-1/4x = -36

x = -36/-1/4

x = 144

The function is decreasing on the interval (-∞,∞)

This means that, throughout the whole graph, the slope is negative.
