What is the product of the polynomials (2x - x + 1)(x-3) ?

A. 2x3-7x2 + 3x - 3
B. 2r3-6x2 + 4x - 3
C. 2x3-7x2 + 4x - 3
D. 2x3 -6x2 + 3x - 3

Step-by-step explanation:

since they have the Same slop (1) and different y-intercepts then they're parallel and there isn't a solution for this.

Answer:

The perimeter is 37 inches (3 ft. 1 in.)

Step-by-step explanation:

24 + 13 = 37

12 x 2 = 24

6.5 x 2 = 13

Answer:

x^2 + 10x + 25.

Step-by-step explanation:

When you have questions like these, where there is an (x + something)^2,

you just need to put it into this form:

x^2 + ____x + ____.

For the first blank, add 5 + 5 in this case.

For the second blank, multiply 5 * 5.

5 + 5 = 10.

5 * 5 = 25.

So the final answer is:

x^2 + 10x + 25.

Answer: No

its okay i had to look it up to make sure i was right lol

Can i have brianliet plz

Answer:

No, I don't think so.

Step-by-step explanation:

I don't think this is a function because the triangle is made of multiple points. Some of these points share the same x point, so this concludes that a triangle on a graph is not a function.

Hope it helps!

Answer:

f(0)=9

Step-by-step explanation:

All you do is plug in x=0 into the function.

In this case:

f(x)=10^x+8

f(0)=10^0+8

f(0)=1+8

f(0)=9

Therefore, f(0)=9

Answer:

9

Step-by-step explanation:

You put 0 for x

10^0=1, so 1 +8 is 9

Answer:

x<-60

Step-by-step explanation:

just used photomath

Answer:

x<-60

work:

(-10) x/-10 > 6 (-10)

x< -60 flip sign because multiply by negative number

6 gifts. 6 yards of ribbon.

Again, what is the shape?

Answer:

46p + 31

hope it's helpful

Answer:

46p + 31

Step-by-step explanation:

Distribute : 5(6p + 5 ) to get 30p+25

Distribute : 2(8p + 3) to get 16p + 6

new expression : 30p + 25 + 16p + 6

Add these together to get : 46p + 31

Answer:

B.) (-5, 6)

Step-by-step explanation:

to solve algebraically, test the coordinate pairs in the equation [tex]y = -\frac{2}{5}x + 4[/tex]

to solve graphically, enter the equation [tex]y = -\frac{2}{5}x + 4[/tex] into a graphing calculator and graph the coordinate pairs as well to see which one is on the line.

(2, 3) is NOT a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

plug in 2 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

now plug in 3 for y.

your equation is now 3 = -2/5(2) + 4. begin simplifying by multiplying -2/5 and 2.

now add -0.8 + 4 to simplify the rest of the right side of the equation.

3 and 3.2 are not equal, therefore (2, 3) is not a solution.

(-5, 6) IS a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

plug in -5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

now plug in 6 for y.

your equation is now 6 = -2/5(-5) + 4. begin simplifying by multiplying -2/5 and -5.

now add 2 + 4 to simplify the rest of the right side of the equation.

6 and 6 are equal, therefore (-5, 6) is a solution.

although we have identified (-5, 6) as a solution, i'm still going to check the rest of the points just to be sure! :)

(6, 2) is NOT a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

plug in 6 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

now plug in 2 for y.

your equation is now 2 = -2/5(6) + 4. begin simplifying by multiplying -2/5 and 6.

now add -2.4 + 4 to simplify the rest of the right side of the equation.

2 and 1.6 are not equal, therefore (6, 2) is not a solution.

(-2/5, 4) is NOT a solution.

i see that they want to trick you with this one by using the values that are in other spots in the equation... that's crafty

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

plug in -2/5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

now plug in 4 for y.

your equation is now 4 = -2/5(-2/5) + 4. begin simplifying by multiplying -2/5 and -2/5.

now add 0.16 + 4 to simplify the rest of the right side of the equation.

4 and 4.16 are not equal, therefore (-2/5, 4) is not a solution.

as for finding the solution on a graph, enter the equation for the line as well as the coordinate pairs into a graphing calculator. here i used a handy little site called desmos in order to graph all of this. the first photo i attached contains what i entered into the calculator, and the second photo i attached shows the graph. as you can see, the only point that is actually on the line is (-5, 6), which is why (-5, 6) is a solution to [tex]y = -\frac{2}{5}x + 4[/tex] , and the other coordinate pairs are not solutions to that equation because they are not on the line.

i hope this helps! have a lovely rest of your day <3

Answer:

x = 31, y = 53, z = 96

Step-by-step explanation:

i got this question ina test so yea

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]

So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.

[tex]x_{1} = -9[/tex]  and [tex]y_{1} = 7[/tex]

[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)

[tex]\frac{-9 + x_{2} }{2} = 10[/tex]           [tex]\frac{7 + y_{2} }{2} = -3[/tex]

-9 + [tex]x_{2}[/tex] = 20         7 + [tex]y_{2} = -6[/tex]

[tex]x_{2} = 29[/tex]                    [tex]y_{2} = -13[/tex]

endpoint is (29, -13)

Answer:

a=9 , b=14

Step-by-step explanation:

Just do the operation (x+7)(x+2)

x(x)+x(2)+7(x)+7(2)

x^2+2x+7x+14

x^2+9x+14

So a=9 and b=14

Answer:

Lucas

Step-by-step explanation:

Katie's response would mean that no matter how many ants there are, there will only always be 6 legs, which is incorrect.

Lucas's response would mean that the number of ants would equal the total number of legs divided by 6, which is correct.

8.6+6.6>3.3 is true

6.6+3.3>8.6 is true

3.3+8.6>6.6 is true

Answer:

(3, 1/2)

Step-by-step explanation:

The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3.  The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.

Thus the midpoint of AB is (3, 1/2).
