Find the slope of the line that passes through the points (2, -5) and (7, 1) Step 1: Choose (x1, y1) X1= ___ y1=___

Scientific notation is a way of expression really large or really small numbers.

For instance, 1000000 in scientific notation would be 1 x 10^6

Answer:

Scientific notation is way of writing very small or very large numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Answer:

1 : equal in force, amount, or value also : equal in area or volume but not superposable a square equivalent to a triangle. 2a : like in signification or import. b : having logical equivalence equivalent statements. 3 : corresponding or virtually identical especially in effect or function.

Answer:

The ratio for AD:DC is 2:3

Step-by-step explanation:

The given information are;

The ratio by which point B splits AC as AB:BC = 2:1

The ratio by which point D splits AB as AD:DB = 3:2

Therefore, we have;

The fraction of AC that is equal to AB is given as follows;

AB = 2/(2 + 1) × AC = 2/3 × AC

AB = 2/3 × AC

Similarly

BC = 1/3 × AC

Also the fraction of AB that is equal to AD is given as follows;

AD = 3/(3 + 2) × AB = 3/5 × AB

AD = 3/5 × AB

Therefore, the fraction of AC that is equal to AD is given as follows;

AD = 3/5 × AB = 3/5 × 2/3 × AC = 2/5 × AC

Therefore, DC = (1 - 2/5) × AC = 3/5 × AC

Which gives the ration of AD to DC or AD:DC as being;

AD:DC = 2/5 × AC : 3/5 × AC  = 2/5:3/5 = 2:3

The ratio for AD:DC = 2:3.

Answer:

PQ = 23, QR = 17

Step-by-step explanation:

PR = PQ + QR = 40

Substitute PR and QR into the equation above

40 = 5x - 2 + x + 12

Combine like terms

40 = 6x + 10

Subtract 10 from both sides

30 = 6x

Divide both sides by 6

5 = x

PQ = 5x - 2= 5(5) - 2 = 23

Remember, PR = PQ + QR

40 = 23 + QR

Subtract 23 from both sides.

17 = QR

PQ = 23

a negative slope

Answer:

Y=-16

Step-by-step explanation:

-3(6)+3

-18+2

y=-16

Answer:

-16

Step-by-step explanation:

We can evaluate y = -3x + 2 for x = 6.  Substituting 6 for x in y = -3x +2, we get:

y = -3(6) + 2 = -18 + 2 = -16

The equation  y = -3x + 2 has already been "solved" for y.  At this point you are evaluating this equation  at x = 6.

Answer:

123,876.3 = 7 sig figs

1,236,840= 7 sig figs

422000 = 3 sig figs

0.000000000000211= 3 sig figs

0.000238 = 3 sig figs

0.0000205 = 3 sig figs

Step-by-step explanation:

Leading zeros are not significant, trailing zeros with no decimal are not significant. Whole numbers are always significant.

Answer:

7

Step-by-step explanation:

Let’s think about this like a number line.

If we have a number line with the ends of F and H, and G is somewhere in between, it would look something like this.

F———-G———H

We know that FH = 19 and that FG is 12.

This means that GH will be the FH - FG

[tex]19 - 12 = 7[/tex]

So FG is 7.

Answer:

[tex]x =\frac{(2y-6)}{3}[/tex]

Step-by-step explanation:

2y = 3(2+x)  {Use distributive rule}

2y = 3*2 + 3*x

2y = 6 + 3x      {Subtract 3 form both sides}

2y - 6 = 3x       {Divide both sides by 3}    

[tex]\frac{(2y-6)}{3}=x[/tex]

Answer:

y=[tex]\frac{x+9}{n}[/tex]

Step-by-step explanation:

x/y=n-9

x= y(n-9)

x= yn-9n

-yn= -x-9n

yn= x+9n

y=[tex]\frac{x+9}{n}[/tex]

Answer: (6z-12) = (-12+6z)

Step-by-step explanation:

Okay, so what you want to do is multiply 3(2z-4) and you should get (6z-12). Then you do the exact same thing on the other side, -6(2-z), and you should get (-12+6z). Then you put those together, so it would look like (6z-12) = (-12+6z).

Answer:

18-ft.

Step-by-step explanation:

WHEW. Just buy it for 11.52. If you bought 18 yd of butcher paper from the 3 yd roll you would be spending almost 52 dollars!

Answer: 3-Yard roll or butcher paper

Step-by-step explanation:

3 Yards = 9 Feet. 3 yards is half of 18 feet. And the cost of 3 yards is only 2.88, And since it is half of the amount of 18 feet, we multiply by two. ($5.76). Meaning 3 Yards is better to buy.
