How do you find the point slope form for the points (2,7) and (-1,9)?

Answers

Answer:

y = -2/3 x + 25/3

Step-by-step explanation:

The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.

Our equation needs to be in y = mx + b form.

We can plug in (2, 7) as our (x, y) and find b:

7 = -2/3 (2) + b

b = 7 + 4/3 = 25 / 3.

Therefore, our equation is y = -2/3 x + 25/3

Use the Equation(in the picture) and plug in your variables to find m(slope)

[tex]\frac{9-7}{-1-2} = \frac{-2}{3} = -0.67[/tex]

Answers

Answer:

the second one

Step-by-step explanation:

if the two given angles are the same, that means there is the same distance between their lines.

cbd is one angle, being shared by both of the points in the answer, does this make sense?

(a) An angle measures 83°. What is the measure of its supplement?
(b) An angle measures 65°. What is the measure of its complement?

Answers

supplementary angles add up to 180°, while complementary angles add up to 90°. to find the supplementary angle to 83° just subtract it from 180°.

180 - 83 = 97°

to find the complementary angle, just subtract 65° from 90°.

90 - 65 = 25°

97° is the answer to Part A, and 25° is the answer to Part B. hope this helps!

Step-by-step explanation:

This is because none of the numbers change places the only things that move are the parenthesis which correspond with the associative property.

If a = 3 what is the value of b in the equation 2a+b=13? And can you explain?

Answers

Answer:

b=7

Step-by-step explanation:

Plug 3 into a since a=3.

2(3)+b=13

Then solve for 2(3)

6+b=13

Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)

b=13-6

b=7

When there is a letter next to a number you multiply so it would be 2 x A and a is 3 so 2x3=6 but to get the answer you have to subtract 6 from the total 13 and you get 7

So the answer is 7!

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by

Answers

multiplying the numerator and denominator by (8+3i)

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

Given

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by

Expression; [tex]\rm \dfrac{4+2i}{8-3i}[/tex]

A complex conjugate is formed by changing the sign between two terms in a complex number i.e. a+ ib has conjugate a-ib and a- ib has conjugate like a+ ib.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

[tex]=\rm \dfrac{4+2i}{8-3i}\\\\= \rm \dfrac{4+2i}{8-3i}\times \dfrac{8+3i}{8+3i}\\\\= \dfrac{(4+2i) \times (8+3i)}{(8)^2-(-3i)^2}\\\\= \dfrac{32+12i+16i+6i^2}{64+9}\\\\=\dfrac{32+28i+6i^2}{73}[/tex]

Hence, The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

3⅞ is the answer to the question.

Step-by-step explanation:

The ten lightest tomatoes are in ¼, ⅜, ½, ⅝ and ⅞.

In ¼, there are 3 tomatoes, so that would be “¼×3=¾”.

In ⅜, there are 2 tomatoes, so that would be “⅜×2=¾”.

In ½, there are 3 tomatoes, so it would be “½×3=3/2”.

In ⅝, there is 1 tomato, so it would be “⅝×1=⅝”.

In ⅞, there is 1 tomato, so that would be “⅞×1=⅞”.

Now add all together:

¾ + ¾ + 3/2 + ⅝ + ⅞

= 5+5+7+6+8/8

= 31/8

= 3⅞
