Which ordered pair is a solution to the equation y = 2x + 1?

A. (8, 17)
B. (9,16)
C. (10, 12)
D. (13, 17)

Answer:

D

Step-by-step explanation:

Multiply the numerator and denominator by the conjugate of the denominator.

Note that i² = - 1

The conjugate of 10 + 3i is 10 - 3i , then

[tex]\frac{(3+5i)(10-3i)}{(10+3i)(10-3i)}[/tex] ← Expand numerator/denominator using FOIL

= [tex]\frac{30-9i+50i-15i^2}{100-30i+30i-9i^2}[/tex] ← simplify

= [tex]\frac{30+41i+15}{100+9}[/tex]

= [tex]\frac{45+41i}{109}[/tex] → D

Step-by-step explanation:

You can plug it in to a calculator, or use pemdas: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

The correct answer is option (D).

To find from graph below which functions.

Coordinate geometry is defined as the study of geometry using the coordinate points.

First at the left side of the graph. The shape that it is an [tex]x^{3}[/tex]  function. also the filled in circle means inclusive. so that when x <= (whatever number). It is impossible to tell for sure with this graph if it is on 1. for the first part. the only answer that has less than or equal to is the last one, D. To look at the right side that it is open circle. It is >.

So, the answer is Option (D).

Step-by-step explanation:

Let the angles of quadrilateral be

X, 2x, 3x, 4x

Sum of all angles of quadrilateral = 360

X+2x+3x+4x = 360

10x = 360

X = 360/10 = 36

Ans: the four angles are

X = 36

2x = 2 X 36 = 72

3x = 3 X 36 = 108

4x 4 X 36 = 144

Answer:

Let x = the number of lbs of Type A coffee.

We know that this month's blend used 3 times as many pounds of type B coffee as type A coffee.

Total lbs of coffee = x + 3x

The total cost then is:

($ cost for Type A)(x) + ($ cost for Type B)(3x) = $717.60

$5.65x + $4.25(3x) = $717.60

$5.65x + $12.75x = $717.60

$18.40x = $717.60

x = 39 lbs

Answer:

x =  (2c - 3b + 5) / (c - b).

Step-by-step explanation:

c(x - 2) - 5 = b(x - 3)

cx - 2c - 5 = bx - 3b          Bring the terms in x to left side:-

cx - bx  - 2c - 5 = -3b        Bring  other terms to right side:-

cx - bx = 2c  - 3b  + 5

x(c - b) =  2c  - 3b  + 5         Divide both sides by c - b:-

x =  (2c - 3b + 5) / (c - b).

-150 = -50h

h = 3

Answer:

Step-by-step explanation:

This equation is of the form y = kx, where k is the constant of variation. In our case, this is 2/5. One thing that separates a direct variation from simply a line (although a direct variation does in fact represent a line when graphed), is that the graph of a direct variation will ALWAYS go through the origin. That means that it will never have the "+ k" at the end of its equation and its y-intercept is always 0.

Answer:

Boys: 21.22 Girls: 16.89

Answer: A

Step-by-step explanation:

Add all the data points and divide it by the number of the data points.

growth rate:

[tex]=\frac{8}{365}[/tex]Derek is not growing like a weed because the weed grows at 0.1 inch per day, while he grows at a rate of 0.022 inch per day.

The number of days in a year = 365

The question says that D'rek grew at the rate of 8 inches in the last year'

D'reks growth rate:

[tex]=\frac{8}{365}[/tex]

= 0.022 inch per day

From the calculation above, Derek is growing at the rate of 0.022 inch per day. But the question says that the weed grows at the rate of 0.1 inch per day

In conclusion, Derek is not growing like a weed, his growth rate differs from that of the weed.
