Hey Mattchance666,

Lets solve this equation together,

The question we are enquiring is : What is the value of i ^20+1?

To solve this equation: we have to use the Power Reduction Rule.

Where I^n=I{n mod 4}

In this case: I^20 = I^{5*4+0}=I^0

1 + 1 = 2

Hope this helps,

Will Mark Brainlest help pleaseeeeee

Masja [62]

Answer:

h(2) = 7/4

h(-3) = -2

h(-2) = 11/(-8)

h(-3) - h(-2) = -(5/8)

Step-by-step explanation:

h(x) = (2x^2-x+1) / (3x-2)

h(2) = (2*2^2 - 2 + 1) / (3*2 - 2)

= (8 - 2 + 1) / (6 - 2)

= 7/4

h(-3) = {2*(-3)^2 - (-3) + 1} / {3*(-3) - 2}

= (18 + 3 + 1) / (-9 - 2)

= 22/(-11)

= -2

h(-2) = {2*(-2)^2 - (-2) + 1} / {3*(-2) - 2}

= (8 + 2 + 1) / (-6 - 2)

= 11/(-8)

h(-3) - h(-2) = (-2) - {11/(-8)}

= -(5/8)

Hope this will help. Please give me brainliest.

Mark and Don are planning to sell each other their marble collections at a garage sale. If Don has 1 more than 3 times the numbe

Volgvan

Answer: Mark has 28 marbles while Don has 85 marbles.

Step-by-step explanation:

Let x represent the number of marbles that Mark has.

Let y represent the number of marbles that Don has.

If Don has 1 more than 3 times the number of marbles Mark has, it means that

y = 3x + 1

The total number of marbles is 113. It means that

x + y = 113- - - - - - - - - - - - 1

Substituting y = 3x + 1 into equation 1, it becomes

x + 3x + 1 = 113

4x + 1 = 113

4x = 113 - 1 = 112

x = 112/4

x = 28

y = 3x + 1 = 3 × 28 + 1

y = 85

The slope of a line passing through H (-2, 5) is -3/4. Which ordered pair represents a point on this line?

oksano4ka [1.4K]

Answer:
(6,-1)

Explanation:
The slope of the line can be calculated using the following formula:
slope = $\frac{y2-y1}{x2-x1}$

We are given that:
slope = -0.75
point (x1,y1) is (-2,5)

We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.

For point (6,-1):
slope = $\frac{-1-5}{6--2}$ = -0.75 ........> accepted choice

For point (2,8):
slope = $\frac{8-5}{2--2}$ = 0.75 ........> rejected choice

For point (-5,1):
slope = $\frac{1-5}{-5--2}$ = 4/3 ........> rejected choice

For point (1,1):
slope = $\frac{1-5}{1--2}$ = -4/3 ........> rejected choice

Therefore, the first option is the only correct one.

Hope this helps :)
