Solve 48-5i=-4x+10yi

Answer:

Step-by-step explanation:

1) 6  and -5

x₁ + x₂  = 6 +(-5) = 1

x₁* x₂   = 6*(-5) = -30

x² -(x₁ + x₂)x + (x₁* x₂)=0

x² - x  - 30 = 0

2) 4 and 7

x₁ + x₂  =4 + 7 = 11

x₁* x₂   = 4*7 = 28

x² - 11x + 28 = 0

3) 1 and -10

x₁ + x₂  = 1 +(-10) = -9

x₁* x₂   = 1*(-10) = -10

x²  - 9x - 10 = 0

4) -9 and 0

x₁ + x₂  = -9 + 0 = -9

x₁* x₂   = 0

x² - (-9)x  = 0

x² + 9x = 0

5)2 and 6

x₁ + x₂  = 2 + 6 = 8

x₁* x₂   = 2*6 = 12

x² -8x + 12 = 0

8) 2 +√3  and 2 - √3

x₁ + x₂  = 2+ √3 + 2 - √3 = 4

x₁* x₂   = (2 + √3)(2 - √3) = 2² - (√3)² 4 - 3 = 1

x² - 4x + 1 = 0

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of (2a - 13) ÷ b/15 when a = -2/5 and b = -8.25 is  [tex]25\frac{75}{825}[/tex]

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(2a - 13) ÷ b/15

The value of (2a - 13) ÷ b/15 when a = -2/5 and b = -8.25.

= (2a - 13) ÷ b/15

= (2 x (-2/5) - 13) ÷ -8.25 / 15

= (-4/5 - 13 ) ÷ -8.25 / 15

= (-4 - 65) / 5 ÷ -8.25 / 15

= -69/5 ÷ -8.25/15

= -69/5 x -15/8.25

= 69 x 3 / 8.25

= 207 / 8.25

= 20700/825

We will write this in a mixed fraction.

= [tex]25\frac{75}{825}[/tex]

Thus,

The value of (2a - 13) ÷ b/15 when a = -2/5 and b = -8.25 is  [tex]25\frac{75}{825}[/tex]

Answer:

3:7

Step-by-step explanation:

The number of triangles is 6.

The number of squares is 8.

The total number of shapes is 14.

The unsimplified ratio of triangles to total shapes is 6:14.

The bigger number that both 6 and 14 can be divided by is 3.

That makes the ratio 3:7, and it cannot be simplified further.

Answer:

There are no factor that you can find that when two factors are multiply together your get a product of -20 and when you add then you get -12

Step-by-step explanation:

===================================================

Explanation:

Multiply the denominators to get 3*4 = 12. We'll use this value to set up the number of slices we start with.

If we started with 12 slices, then 1/3 of this is (1/3)*12 = 4 slices. So Carlos ate 4 slices. There are 12-4 = 8 slices left.

1/4 of that value is (1/4)*8 = 2 which is the number of slices given to his friend.

Divide the number of slices given to the friend (2) over the number we started with (12) to get 2/12 = 1/6

-----------------------

Another approach:

If Carlos ate 1/3 of the full pie, then there are 2/3 of it left.

1/4 of this is (1/4)*(2/3) = (1*2)/(4*3) = 2/12 = 1/6 which represents the fractional amount of the original pie given to the friend.

Answer:

52 %

Step-by-step explanation:

Total number of squares = 100

Number of shaded squares = 52

% of shaded squares

= ( 52 / 100 ) x 100

= ( 52 x 100 ) / 100

= 5200 / 100

= 52 %

Step-by-step explanation:

If 3 thermometers totaled -15, then they share that value equally.

The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists

Let x represent the number of cyclists.

Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:

Revenue = 60x + 15000

Also, the cost of the race is $18 per entry, hence:

Cost = 18x

They need to raise at least $57,000, hence:

Profit ≥ 57000

Revenue - Cost ≥ 57000

(60x + 15000) - 18x ≥ 57000

42x ≥ 42000

x ≥ 1000

Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclists

Answer:

∠ 5 = 122° , ∠ 6 = 58°

Step-by-step explanation:

∠ 5 and 122° are vertically opposite and are congruent , then

∠ 5 = 122°

∠ 5 and ∠ 6 are same- side interior angles and sum to 180°

∠ 5 + ∠ 6 = 180° , that is

122° + ∠ 6 = 180° ( subtract 122° from both sides )

∠ 6 = 58°

Step-by-step explanation:

The number of individuals that work for the company is 272 workers.

Given,

The Parker company employs 68 part-time workers.

This represents 4% of the total workforce.

We need to find out how many individuals work for the company.

Percentage is a fraction or a ratio in which the value of whole is always 100.

Find the total workforce.

Total workforce = 100%

We have,

4% = 68 workers

Multiply 25 on both sides.

25 x 4% = 4 x 68 workers

100% = 272 workers.

This means the number of individuals that work for the company is 272 workers.

Thus the number of individuals that work for the company is 272 workers.

The equation to represent this scenario is d(t) = -2t + 10.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, Harry starts 10 miles away from home.

For each minute his distance decreases by two miles.

Assuming no. of minutes to be 't' and distance to be d(t).
