Answer:

2x^2+7x-4

Step-by-step explanation:

2x-x=x the 4+1=5 so x=5

Step-by-step explanation:

Answer: -2

Explanation: The -2 is called the x-coordinate

or horizontal move from the origin.

All points are written in the form (x, y).

Given:

The function is

[tex]f(x)=x^3-3x^2+5x-15[/tex]

To find:

The root of the function from the given possible roots.

Solution:

We have,

[tex]f(x)=x^3-3x^2+5x-15[/tex]

At x=-3,

[tex]f(-3)=(-3)^3-3(-3)^2+5(-3)-15[/tex]

[tex]f(-3)=-27-27-15-15[/tex]

[tex]f(-3)=-84\neq 0[/tex]

At x=-1,

[tex]f(-1)=(-1)^3-3(-1)^2+5(-1)-15[/tex]

[tex]f(-1)=-1-3-5-15[/tex]

[tex]f(-1)=-24\neq 0[/tex]

At x=1,

[tex]f(1)=(1)^3-3(1)^2+5(1)-15[/tex]

[tex]f(1)=1-3+5-15[/tex]

[tex]f(1)=-12\neq 0[/tex]

At x=3,

[tex]f(3)=(3)^3-3(3)^2+5(3)-15[/tex]

[tex]f(3)=27-27+15-15[/tex]

[tex]f(3)=0[/tex]

Since, the value of given function is 0 at only x=3, therefore 3 is a root of given function.

Hence, the correct option is D.

Answer:

The student did not distribute correctly

Answer:

B

Step-by-step explanation:

Complementary means that two angles add up to 90°.

We can make an equation to resemble the problem and solve for x.

(4x - 2) + (11x + 17) = 90

15x + 15 = 90

15x = 75

x = 5

Best of Luck!

Answer: X= -3

Step-by-step explanation: If f(x)= 3x-1

then you would do the math 3x-1= -10

which makes out to be x= -3

Answer:

y=-1/4x+3

Step-by-step explanation:

put it into y-y1=m(x-x1) form, which gives you y+3=-1/4x(x+0)

(side note: we change the y- to a y+ becuase the y in the point in negative. another side note, the slope is -1/4x because perpendicular slopes are opposite, in this case 4x (or 4/1x) is the opposite of -1/4 x)

then remove the parenthesis. y+3=-1/4x

then isolate y and balance the equation.

y+3-3=-1/4x-3

this gives you the answer of y=-1/4x-3.

Answer:

y=-2x-3

Step-by-step explanation:

The equation of the line in the slope-intercept form is y=x2−2.  

The slope of the perpendicular line is negative inverse: m=−2.

So, the equation of the perpendicular line is y=−2x+a.

To find a, we use the fact that the line should pass through the given point: −3=(−2)⋅(0)+a.

Thus, a=−3.

Therefore, the equation of the line is y=−2x−3.

Answer: y=−2x−3.

James still owes the 27 bucks

Answer:

27$

Step-by-step explanation:

65-38

Answer:

The answer to this question is given below in the explanation section

Step-by-step explanation:

This is a simple division question.

In division there are some terms used that are:

Dividend: The number which we divide is called a dividend. In this case, 425 is a dividend

Divisor: The number by which we divide is called the divisor. In our question, it is 15.

Quotient: The result obtained is called the quotient.

Remainder: The number left over is called the remainder.

So the answer to this question is:

452/15= 30.133

so the answer is 30.1333

Answer:

-3, 1, 2

Step-by-step explanation:

the range is the y- values

Answer:

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Step-by-step explanation:

Answer: On the first day, Shelly rode 10 miles on first day.

On the second day, Shelly rode 8 miles.

On the third day, Shelly rode 12 miles.

Step-by-step explanation:

Let x = distance rod eon first day.

Shelly rode her bike a total of 30 miles over a three-day period.

Then as per given,

Distance rode on second day = [tex]\dfrac45x[/tex]

Distance rode on third day [tex]=\dfrac32\times\text{ Distance rode on second day}[/tex]

[tex]=\dfrac32\times\dfrac45x=\dfrac{6}{5}x[/tex]

Total distance rode = [tex]x+\dfrac45 x+\dfrac65x=30[/tex]

[tex]\Rightarrow\ \dfrac{5x+4x+6x}{5}=30\\\\\Rightarrow\ \dfrac{15x}{5}=30\\\\\Rightarrow\ 3x=30\\\\\Rightarrow\ x=\dfrac{30}{3}\\\\\Rightarrow\ x=10[/tex]

Hence, She rode 10 miles on first day.

Distance rode on second day = [tex]\dfrac45\times10=4\times2=8\text{ miles}[/tex]

Distance rode on third day [tex]=\dfrac{3}{2}\times8=3\times4=12\text{ miles}[/tex]

Answer:

119 degrees

Step-by-step explanation:

We know that a full straight line is 180 degrees. This angle is 61 degrees, so we subtract 61 from 180.

180 - 61 = 119 degrees

I hope this helped, please mark Brainliest, thank you!

Answer:

119

Step-by-step explanation:

a line equals 180 degrees, so just subtract 61 from 180

Answer:

multiple --> the __ of 13 include 13, 26, 39..

factor --> the __ of 10 include 1, 2, 5, 10

in terms of --> solve for variable

range --> all possible values that can be generated by the function (output)

Step-by-step explanation:

this is too much explain im srry just trust me :D

you'll start to understand these eventually   hopefully

Answer:

Step-by-step explanation:

Given the equation

4x-2(3x-4)+4 = -x+3(x+1)+1

Open the parenthesis on both sides

4x-6x+8+4 = -x+3x+3+1

-2x+12 = 2x+4

Collect like terms

-2x-2x = 4-12

-4x = -8

Divide both sides by -4

-4x/-4 = -8/-4

x = 2

Hence the value of x is 2

Answer:

Is there a picture to go with the question??

Step-by-step explanation:

Perimeter of a rectangular plot = 36 m.

length of the plot

Let the length of the plot be x and it's breadth be y.

We know that,

Perimeter of a rectangle = 2(length + breadth)

⟹ 2(x + y) = 36

⟹ x + y = 36/2

⟹ x = 18 - y -- equation (1)

Also,

If length is increased by 6 m & breadth is decreased by 3 m , the area remains same.

Area of a rectangle = length * breadth

So,

(x + 6) * (y - 3) = xy

⟹ x(y - 3) + 6(y - 3) = xy

⟹ xy - 3x + 6y - 18 = xy

Substitute the value of x from equation (1).

⟹ - 3(18 - y) + 6y = 18

⟹ - 54 + 3y + 6y = 18

⟹ 9y = 18 + 54

⟹ y = 72/9

⟹ y = 8 m

Substitute the value of y in equation (1).

⟹ x = 18 - 8

⟹ x = 10 m

Hence,

Length (x) = 10 m

Breadth (y) = 8 m.

∴ The length of the plot is 10 m.

I hope it will help you.

Regards.
