The pattern is times 4, minus 2. So, 22 x 4 = 88-6 = 86, then 86 x 4 = 344-2 = 342

So,

**1, 2, 6, 22, 86, 342** is your answer

I think the pattern goes like this 1, 2, 6, 22, 86, 342

Question

Use elimination to find the value of x in the solution for the system of equations. 2x+2y=10,2x-3y=5

Solution 1

Elimination

2x+2y=10

2x-3y=5

multiply first equatn by -1

-2x-2y=-10

add to second equation

2x-3y=5

__-2x-2y=-10 +__

0x-5y=-5

-5y=-5

divide both sides by 5

-y=-1

muitply b-1

y=1

subsitue

2x+2y=10

2x+2(1)=10

2x+2=10

subtract 2

2x=8

divide 2

x=4

Question

Which statements about the graph of the function f * x equals x ^ 2 - 4x + 2 are true check all that apply

Solution 1

If the function is -x^2 -4x + 2 (you skipped the operator between -4x and 2), then:

1) The domain is all the real numbers (-infinity, + infinity)

2) The range is all the real numbers below 6, given that the vertex is (2,6) and the function opens down (because the coefficient of x^2 is negative).

3) The function increases over the interval (-infinity, 2) and decreases over the interval (2,+infinity).

4) The y-intercept is the value of the function when x =0, so it is 2 (positive).

Then, the only true statement is that the range is y such that y is 6 or below

Question

Please help!!! Mark is learning to snowboard. The club charges $10 per hour for snowboard lessons and $40 for the lift ticket and a snowboard rental. Which value represents the rate of change for this scenario?

Solution 1

H represents the number of hours:

**10h + 40**

(40 represents, well $40)

(40 represents, well $40)

Solution 2

the answer is 40 + 10h

Question

Which of the following are the correct properties of slope? Check all that apply.
A.The slope of a line is always positive.
B.If two lines have the same slope, then they are the same line.
C.A steep line has negative slope.
D.The slope of a line that moves up from left to right is positive.
E.Some lines have an undefined slope.

Solution 1

Using concepts for the **equation of a line**, the correct options are:

D.The slope of a line that moves up from left to right is positive.

E.Some lines have an undefined slope.

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

The** equation of a line** is given by:

In which m is the **slope **and b is the y-intercept.

Among the **properties **of the **slope**, there are:

- The
**slope**is the**rate of change**, that is, how much y changes when x changes by 1. - If the
**slope**is**positive**, the**line**is**increasing**, that is, it moves up from left to right,**otherwise**it is**decreasing,**that is, it moves down from left to right. - The
**higher**the**absolute value**of the slope, the**steeper**the line is. - Constant
**horizontal line**has slope**0**. - Constant
**vertical line**has slope**undefined**. - If two
**lines**are**parallel**, they have the**same slope.** - If two lines are
**perpendicular**, the**multiplication**of their**slopes**is**-1.**

Thus, the **correct options** are:

D.The slope of a line that moves up from left to right is positive.

E.Some lines have an undefined slope.

Question

Use the difference of squares theorem to find the solution of the following equation: v^2 = 252

Solution 1

V^2 = 252

v^2 - 252 = 0

(v - sqrt252)(v + sqrt252) = 0

so the 2 solutions are sqrt252 and - sqrt252

= 15.87 and -15.87 to nearest hundredth.

v^2 - 252 = 0

(v - sqrt252)(v + sqrt252) = 0

so the 2 solutions are sqrt252 and - sqrt252

= 15.87 and -15.87 to nearest hundredth.

Question

How do I solved this question. 1/3c=3/8;c=3/4

Solution 1

1/3c = 3/8

multiply both sides by 3:-

c = 3*3/8 = 9/8

c = 9/8 or 1 1/8

multiply both sides by 3:-

c = 3*3/8 = 9/8

c = 9/8 or 1 1/8

Question

Question

FIRST CORRECT ANSWER GETS BRAINLIEST!!! PLS HELP ME!!!!! ONEHUNDRED POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ruth was hauling a wide load out of portland. at 7:00 am she headed north from exit 102 at an average speed of 35 pmh. michael headed north from the same exit at 9:00 am in his pontiac. by 3:00 pm the same day michael was 20 miles ahead of ruth. what was michael's average speed

Solution 1

ruth was out of portland at 35mph at 7:00am

so at 9 am, she was 70 mile ahead of michael

but michael was 20 miles ahead by 3 pm.

so in 6 hours, he went past ruth by 90 miles which is 90/6 = 15mph

michael speed = ruth speed + 15

= 35 + 15

= 50mph

so at 9 am, she was 70 mile ahead of michael

but michael was 20 miles ahead by 3 pm.

so in 6 hours, he went past ruth by 90 miles which is 90/6 = 15mph

michael speed = ruth speed + 15

= 35 + 15

= 50mph

Question

Which number is larger 0.775 or 0.95

Solution 1

0.95 is greater because you can just add a zero to compare it so then it will be 0.950. So 0.775 < 0.950. You can also imagine what is bigger 775 or 950. 950 would be greater than 0.775.

Hope it helped :)

Question

The scores of several classmates on a language arts test are shown below: 86 points 87 points 87 points 94 points 95 points 82 points 78 points 89 points 80 points 84 points What is the median score for these students? 87.5 points 87 points 86.5 points 86 points

Solution 1

**Answer:**

Your answer would be 87.5

**Step-by-step explanation:**

The reason that I know is because 87 is the most used number in this situation which it then makes it 87.5.

Solution 2

**Answer:**

87.5 would be the correct answer!

**Step-by-step explanation:**

if you follow every set of points then the median would be 87.5
