Simplified answer for 13x^8 + 18:
x x • (13x7 + 18)
Answer:
2x + y - 1 = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 2y + 4 = 0 ( subtract x + 4 from both sides )
- 2y = - x - 4 ( divide all terms by - 2 )
y = x + 2 ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 2 , thus
y = - 2x + c ← is the partial equation of the perpendicular line
To find c substitute (1, - 1) into the partial equation
- 1 = - 2 + c ⇒ c = - 1 + 2 = 1
y = - 2x + 1 ← in slope intercept form
Subtract - 2x + 1 from both sides
2x + y - 1 = 0 ← in general form
4/3 times 3/4 to cancel out
18 times 4/3
this will be 72/3
72 divided by 3 is 24
X = 24
Answer:
s = 6
Step-by-step explanation:
Goal is to isolate the variable (s)
1/2s = 4s - 21
Subtract 4s from both sides - this cancels out the 4s on the right side and moves it to the left side
1/2s - 4s = -21
To add or subtract fractions, they must have a common denominator
Convert 4s to a fraction over 2
1/2s - 8/2s = -21
Subtract the numerators and keep the denominators
-7/2s = -21
Remember the goal is to isolate the variable
In order to get rid of the -7/2, we multiply by its reciprocal (which is -2/7)
What we do to one side, we must do to the other (this means multiply by -2/7 on both sides
-7/2s × -2/7 = -21 × -2/7
s = -21 × -2/7
Negative × negative = positive
s = 42/7
Divide 42 by 7
s = 6
Answer: 42
Median and Mode is 42
Step-by-step explanation:
25, 35, 40, 42, 42, 50, 54
To find the median cross of numbers on each side when ordered from left to right from least to greatest, the number standing is the median.
To find the mode what number is repeated the most? 42 was numbered twice
