HELP! WILL GIVE BRANLIEST!

Answer:

C and D are correct in my calculations, I'm confused.. ;w;

Step-by-step explanation:

4x + 9 + 79 - x + y = 180

4x - x + y + 79 + 9 = 180

3x + y + 88 = 180

3x + y = 180 - 88

3x + y = 92

y = 92 - 3x

A.) x = 64, y = 50

y = 92 - 3x

(50) = 92 - 3(64)

50 = 92 - 192

50 ≠ - 100

B.) x = 14, y = 152

y = 92 - 3x

(152) = 92 - 3(14)

152 = 92 - 42

152 ≠ 50

C.) x = 23.3, y = 22.1

y = 92 - 3x

(22.1) = 92 - 3(23.3)

22.1 = 92 - 69.9

22.1 = 22.1

D.) x = 14, y = 50

y = 92 - 3x

(50) = 92 - 3(14)

50 = 92 - 42

50 = 50

Step-by-step explanation:

Answer:  Part A:  y = x + 6

Part B:  y = 10

The attachment shows the graphs of these equations.

Step-by-step explanation:

Find the slope, and then the y-intercept. Then write the equation in  Slope-intercept form . y= mx+b

m is the slope. b is the constant, the y-intercept.

First find the slope:  rise/run  

Rise is the difference in y-values  10-7 = 3

Run is the difference between x-values  4 - 1 = 3

The Slope is 3/3   simplify:

m = 1

Use this calculated slope with values of y and x from either of the given coordinates and calculate b

y = mx + b

10 = 1(4) + b  The 1 is not necessary, its "implied" and invisible as a factor in multiplication

10 = 4 + b .  subtract 4 from both sides  10 - 4 = 4 - 4  + b

6 = b

Put these calculated values for m and b into the slope-intercept equation"

y = x + 6

_________

Part B: Step-by-step explanation:  Slope-intercept form . y= mx+b

First find the slope:  rise/run  

Rise is the difference in y-values  10 - 10 = 0

At this point you know that if the slope is 0, it is a horizontal line intersecting the y-axis at the y-value, 10

That graphed line will pass through All x-values.

Answer:

-1.5<-0.5 is the correct answer

Step-by-step explanation:

Answer: x=-4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Step 1: Flip the equation.

2x + 16 = 8

Step 2: Subtract 16 from both sides.

2x + 16 − 16 = 8 − 16

2x = −8

Step 3: Divide both sides by 2.

x = −4

Step-by-step explanation:

Step one:

given

let the total amount of her test be x

we are told that she complete 1/8x  test in 2/5 of  an hour

hence she completed 1/8x in 0.4 hours

let us find the rate at which she completes are test

rate= 1/8x/0.4

convert the numerator to decimal number for easy computation

rate= 0.125x/0.4

rate=0.3125x per hour

Step two:

Hence 1 hour she can finish 0.3125x *1

=0.3125x

She can finish 31.25 % of her test in 1 hour

or 1/16 of her test

27 * 3 = 81

81 * 3 = 243

Each term is 3x the number before it. Therefore:

3 * 3 = 9

The missing number is 9.

Answer:

The missing number would be 9.

Step-by-step explanation:

I found out that the rule is 3 multiplied.

3 times 3 = 9

9 times 3 = 27

27 times 3 = 81

81 times 3 = 243

Answer:

Step-by-step explanation:

Find the graph below;

The standard equation of a line is expressed as y = mx + b where;

m is the slope of the line

b is the y-intercept

Given the expression y = 8.5x

On comparing with the expression

mx = 8.5 x

m = 8.5

b = 0

This means that the line must pass through the origin as shown and the slope of the line is 8.5

The value given below is Discrete. Use the continuity correction and describe the region of the normal distribution that corresponds to the indicated probability:

Probability of more than 3 passengers who do not show up for a flight:

a)the area to the right of 3.5

b)the area to the left of 2.5

c)the area to the right of 2.5

d)the area to the left of 3.5

e)the area between 2.5 and 3.5

Answer:

A: the area to the right of 3.5

Step-by-step explanation:

Option A: The area to the right of 3.5 is the probability that there are more

than 3 passengers that don't show up for a flight.

Option B: The area to the left of 2.5 gives the probability that there will be fewer than 3 passengers that don't show up for a flight.

Option C: The area to the right of 2.5 gives the probability that there are more than 2 passengers that don't show up for a flight.

Option D: The area to the left of 3.5 gives the probability that there are fewer than 4 passengers that don't show up for a flight.

Option E: The area between 2.5 and 3.5 gives the probability that there are exactly 3 passengers that don't show up for a flight.

Thus, the correct option is A.

Answer:

the answer is 2 because between the points it goes up to and over 1 which make the slope 2/1 or 2.

Step-by-step explanation:

The slope is 2. You can figure it out by counting how many units you go up/down and dividing it by how many units you go left/right. This is called “rise over run”
