What is the slope of (-3,0) and (2,7)

Mathematics
2 answers:
Morgarella [4.7K]3 years ago

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}       And plug in the two points

(-3, 0) = (x₁, y₁)

(2, 7) = (x₂, y₂)

(lines go from left to right, so the point furthest to the left is the 1st point)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{7-0}{2-(-3)}    [two negative signs cancel each other out and become positive]

m=\frac{7-0}{2+3}

m=\frac{7}{5}

Answer:

7/5

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, slope can be found using

y2-y2

x2-x1

So we just plug it in:

7-0

2+3

7/5 is your slope

What is the midpoint between -2-3i and 3+9i
Svetlanka [38]

Answer:

1/2 + 3i is the midpoint between -2-3i and 3+9i.

Step-by-step explanation:

Given the complex number

  • -2-3i
  • 3+9i

The formula to find the midpoint of two complex number (a + bi) and (c + di) is:

M=\frac{\left(a+c\right)}{2}+\frac{\left(b+d\right)i}{2}

M=\frac{\left(-2+3\right)}{2}+\frac{\left(-3+\left(9\right)\right)i}{2}

M=\frac{-2+3+\left(-3+9\right)i}{2}

M=\frac{1+6i}{2}

M=\frac{1}{2}+3i

Therefore, 1/2 + 3i is the midpoint between -2-3i and 3+9i.

Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the
Alenkinab [10]

Answer:

The estimated area is 416\frac{13}{16}\ ft^{2}

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft

14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft

step 2

Find the area of one wall

(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}

step 3

Multiply the area of one wall by 3

(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}

step 4

Convert to mixed number

\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}

x = 12√1.5

Step-by-step explanation:

Law of sines.

12/sin45 = x/sin60

x = 12(½√3) / (½√2)

x = 12√3/√2

x = 12√1.5
