What is the product of x^2 - 2x + 3 and x +1?
1) x^3 - x^2 + x + 3
2) x^3 - 2x^2 + 3x
3) x^2 - 3x +2
4) x^2 - x+4

Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (0, - 3)

m = [tex]\frac{-3-5}{0-4}[/tex] = [tex]\frac{-8}{-4}[/tex] = 2

The line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = 2x - 3 ← equation of line

Answer:

C 13 inches

Step-by-step explanation:

Because the plant grows two inches every week so if by the second week it is 7 inches tall just add 3 more weeks or 6 inches of growth to the 7 inches and you get your answer 13 inches

Answer:

y= -4x +3

Step-by-step explanation:

① Rewrite the equation in the form of y=mx+c, to find the gradient of the given line, m.

x -4y= 20

4y= x -20

y= ¼x -5 (÷4 on both sides)

∴ Gradient of line= ¼

② Find the gradient of the new line.

The product of the gradients of perpendicular lines is -1.

¼(gradient of line)= -1

gradient of line

= -1 ÷¼

= -1 ×4

= -4

③ Substitute the value of the gradient into the equation.

y= -4x +c

④ Find the value of c by substituting a pair of coordinates.

When x= 2, y= -5,

-5= -4(2) +c

-5= -8 +c

c= -5 +8 (+8 on both sides)

c= 3

Thus, the equation of the line is y= -4x +3.

Answer:

g(x) will be 4 units under f(x), and will be parallel.

Step-by-step explanation:

The only thing changing is the constant, or y-intercep. This is shown in -4, so 4 units lower. Slope will stay the same because it has not been modified in the expression for g(x).

Answer:

The graph of g(x) is the graph of​​ ​f(x)​ translated 4 units down.

Step-by-step explanation:

Answer: -1 would be greater than negative two, along with 20, 1000.

-2 is a negative number, so any number that is -1 or higher is greater than -2

5.00 for 2 loaves is $2.50 a loaf.

She wants 5 loaves for $12.50

5*2.50= $12.50 so she is correct.

Step-by-step explanation:

Answer:

3 times

Step-by-step explanation:

Firstly we calculate the number of minutes between 8 and 11 am

The number of hours is 3 hours

The number of minutes is 180 minutes since 1 hour is 60 minutes

Now out of 180, to know the number of times that they both leave, we need to get the multiples of both between 0 and 180

The multiples are;

60, 120, 180

This means that they leave together 3 times

The list of single digit primes is {2,3,5,7}. The largest prime is 7, so B = 7 is the largest possible value.

Also note how 707,747 rounds to 708,000 when rounding to 3 significant figures.

Answer:

[tex]V=15.62\ cm^3[/tex]

Step-by-step explanation:

The volume of a cube is given by the formula :

V = s³, where s represents the side length of the cube

The side length of Marie's cube is [tex]2\dfrac{1}{2}\ cm[/tex]. We need to find the volume of her cube. For this, we can use the formula of the volume of a cube such that,

[tex]V=(2\dfrac{1}{2})^3\\\\=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.62\ cm^3[/tex]

So, the volume of her cube is [tex]15.62\ cm^3[/tex].

Answer:

28 pints of yellow paint needed

Step-by-step explanation:

Mixture of green paint = 9 pints of blue paints : 12 pints of yellow paint

Blue paint : yellow paint = 9 : 12

To make the same shade of green paint using using 21 pints of blue paint, how much yellow would you need?

Let

x = pints of yellow pint needed

Blue paint : yellow paint = 21 : x

Equate the ratios to find x

Blue paint : yellow paint

9 : 12 = 21 : x

9/12 = 21/x

Cross multiplication

9 * x = 12 * 21

9x = 252

Divide both sides by 9

x = 252 / 9

= 28

pints of yellow pint needed = x

= 28

Answer:

In the first picture is B

In the second is C

Step-by-step explanation:

Answer:

the first one is A. 2n + 2 and the second is C. 3(y + 2)

Step-by-step explanation:

So for the first one, 5n + 2 - 3n, is basically combining the factors with the variable n, so you subtract 3n from 5n, giving you 2n + 2, or A.

The second one is kinda reverse. You have to find the one that makes the most sense via Distributive Property. So what you do is separate 3 from the others and put y + 6 in parentheses, like this:

3(y + 6)

But this isn't the answer, as if you do the distributive property with this answer, you would get 3y + 18, and that's not what we want to get. So what we have to do is divide 6 by 3, giving us 2, thus giving us our answer of C.
