B. -4, if its right gimme 5 stars, a thank you and a brainliest answer please
The sum is 4x³ + 3x² + 2x – 6.
Solution:
The correct question is given below.
(4x³ – 2x² + 3x – 1) + (5x² – x – 5). What is the sum?
<u>To find the sum of the polynomial:</u>
Sum of (4x³ – 2x² + 3x – 1) and (5x² – x – 5)
= (4x³ – 2x² + 3x – 1) + (5x² – x – 5)
Remove the parentheses.
= 4x³ – 2x² + 3x – 1 + 5x² – x – 5
Group like terms together.
= 4x³ – 2x² + 5x² + 3x – x – 1 – 5
Add the similar elements. i.e the element with same power.
= 4x³ + 3x² + 2x – 1 – 5
Subtract the constant terms.
= 4x³ + 3x² + 2x – 6
The sum is 4x³ + 3x² + 2x – 6.
We are given this explicit formula :
In order to find eighth term let us plug n as 8 in this formula:
subtracting 8-1 first using pemdas rule
multiplying 5 and 7
subtracting 35-6
c(8) = 29
So eighth term is 29.
Answer:
Neither
Step-by-step explanation:
To tell if lines are perpendicular or parallel just from the equations, you need to look at the slopes. So get the equations into slop-intercept form
(y = slope * x + y-intercept)
2x = 14 + y
-14 -14
2x - 14 = y OR y = 2x - 14
*So the slope of the first equation is 2*
4x + 2y = 10
-4x -4x
2y = -4x + 10
/2 /2
y = -4/2 + 10
*So the slope is -2*
For the lines to be parallel, the slopes have to be the same. For them to be perpendicular, the slopes have to be opposite (negative is the opposite of positive and vice versa) and reciprocal (A flipped fraction, so the reciprocal of 2 would be 1/2)
