The product of 2x^3 and 6x^5 is

Answer:

The slope IS NOT 3.

So the statement is FALSE.

Step-by-step explanation:

y = mx + b

If we change the graph shown into the format shown above it would be:

y = 1x - 3

mx = slope

Slope = 1x

b = y-intercept

b = -3

To find the slope you must do:

[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]

y = rise

x = run

In the graph shown, the points are going up and shift to the right 1 unit.

So the slope is: 1x

Therefore, the statement, "The slope is 3" is actually false.

Answer:

= 5/29

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( 8-3)/(13 - -16)

    = ( 8-3)/( 13+16)

   = 5/29

Answer:

4w +7 = 5

Step-by-step explanation:

Have a nice day.

Answer:

4w + 7 = 5

Step-by-step explanation:

"sum" means addition (+), so we're to add two items:

item 1 to be added

"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).

Therefore, 4 x w = 4w

item 2 to be added

This is the number 7

The sum

4w + 7

Now, the sum, equals(=)  the number 5, therefore answer:

4w + 7 = 5

Given:

Length of a rectangular monitor screen is 5 in more than it's width.

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

To find:

The length and width of the screen.

Solution:

Let width of the screen be x inches.

Length of a rectangular monitor screen is 5 in more than it's width. So,

Length of screen = (x+5) inches

Area of screen is

[tex]Area=length\times width[/tex]

[tex]A_1=(x+5)\times x[/tex]

[tex]A_1=x^2+5x\text{ in}^2[/tex]

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

New length = 2(x+5) inches

New width = (x-1) inches

So, new area is

[tex]A_2=2(x+5)(x-1)[/tex]

[tex]A_2=(2x+10)(x-1)[/tex]

[tex]A_2=2x^2+10x-2x-10[/tex]

[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]

Area increased by  170 in².

[tex]A_2-A_1=170[/tex]

[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]

[tex]2x^2+8x-10-x^2-5x=170[/tex]

[tex]x^2+3x-10=170[/tex]

Subtract 170 from both sides.

[tex]x^2+3x-10-170=0[/tex]

[tex]x^2+3x-180=0[/tex]

Splitting the middle term, we get

[tex]x^2+15x-12x-180=0[/tex]

[tex]x(x+15)-12(x+15)=0[/tex]

[tex](x+15)(x-12)=0[/tex]

[tex]x=-15,12[/tex]

Width cannot be negative. So, x=12.

Width = 12 inches

Length = 12+5 = 17 inches

Therefore, the length of screen is 17 inches and width is 12 inches.

Answer:

x = 14

Step-by-step explanation:

These angles are complementary angles, meaning they have a sum of 90°.

4x + 1 + 2x + 5 = 90

6x + 6 = 90 (Added like terms.)

6x = 84 (Subtracted 6 on both sides.)

x = 14 (Divided 6 on both sides.)

[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]

[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]

[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]

[tex]\sf \longmapsto6x + 6 = 90[/tex]

[tex]\sf \longmapsto6x = 90 - 6[/tex]

[tex]\sf \longmapsto \: 6x = 84[/tex]

[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]

[tex]\sf \longmapsto \: x = 14[/tex]

Answer:

x=−8

Step-by-step explanation:

Let's solve your equation step-by-step.

−6=3/8x−2+

1/8x

Step 1: Simplify both sides of the equation.

−6=3/8x−2+1/8x

−6=3/8x+−2+1/8x

−6=(3/8x+1/8x)+(−2)

(Combine Like Terms)

−6=1/2x+−2

−6=1/2x−2

Step 2: Flip the equation.

1/2x−2=−6

Step 3: Add 2 to both sides.

1/2x−2+2=−6+2

1/2x=−4

Step 4: Multiply both sides by 2.

2*(1/2x)=(2)*(−4)

To find the difference between 2 numbers, subtract the bigger one from the smaller one. In this case, 8.4-(-2.2) = 8.4 + 2.2 = 10.6

Answer:

x = - 4

Step-by-step explanation:

Given

[tex]\frac{5}{3}[/tex] x + 4 = [tex]\frac{2}{3}[/tex] x

Multiply through by 3 to clear the fractions

5x + 12 = 2x ( subtract 2x from both sides )

3x + 12 = 0 ( subtract 12 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Answer:

Triangle ABC is not a right triangle because d) it doesn't have a pair of perpendicular sides

Step-by-step explanation:

Perpendicular sides mean that the slopes are "opposite reciprocals" of each other.

Example: slope is 1/2 and the perpendicular line's slope is -2

How? 1/2 changes to 2 (you flip it, reciprocal), and then from 2 to -2 (apply opposite sign)

So when you calculate the slopes of AB, AC, and BC, none of their slopes are opposite reciprocals of each other. You can calculate the slopes of each and compare them if you want to check.

I really hope this helps, do you think you can tell me if you got the answer correct? I'd feel really bad if you got it wrong because of me. All I know is that it's not a right triangle.

Answer:

im gonna assume the 10 - 20 is what the equation is = to if not x wouldnt be = to anything x = -1.5

Step-by-step explanation:

-2.25x + 8.75x = 10-20

-2.25x+ 8.75x = -10

6.50x = -10 divide both sides by 6.5

x = -1.5

Answer:

(8, 0 )

Step-by-step explanation:

Given the 2 equations

y = 8 - x → (1)

y = 5x - 40 → (2)

Substitute y = 5x - 40 into (1)

5x - 40 = 8 - x ( add x to both sides )

6x - 40 = 8 ( add 8 to both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Substitute x = 8 into either of the 2 equations and solve for y

Substituting into (1)

y = 8 - 8 = 0

Solution is (8, 0 )

Answer:

D.

Step-by-step explanation:

I have been doing this in Geometry.

We know perpendicular means opposite recipicoles and opposite slopes.

so.. the slope is 3 to get the y-intercept you do this.

(1, 2) Use the points it gave you and the slope 3 and put it is y=mx + b form

2 = 3(1) + b (I do this because I don't know what b is yet) (b = y-intercept)

2 = 3 + b (subtract 3 on both sides)

-1 = b

The equation is y = 3x - 1

Step-by-step explanation:

Given:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Able's older brother is twice as old as he is.

The combined age of all three siblings is 32.

To find:

The age of Able's younger sister.

Solution:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Age of Able's sister = (x-4)

Able's older brother is twice as old as he is.

Age of Able's older brother = 2x

The combined age of all three siblings is 32.

[tex]x+(x-4)+2x=32[/tex]

[tex]4x-4=32[/tex]

Add 4 on both sides.

[tex]4x=32+4[/tex]

[tex]4x=36[/tex]

Divide both sides by 4.

[tex]x=\dfrac{36}{4}[/tex]

[tex]x=9[/tex]

The age of Able is 9 years. So, age of his younger sister is

[tex]9-4=5[/tex]

Therefore, the age of Able's sister is 5 years.
