Answer is -2x^3 +25x-13
Answer:
(2x² - 5x² - 6x + 7) + (5x³ + x² + 4x - 13)
= -3x² - 6x + 7 + 5x³ + x² + 4x - 13
= 5x³ - 2x² - 2x - 6
Step-by-step explanation:
The price of a television is $245. The sales tax rate is 8%. What is the amount of sales tax?
Answer:
$19.60
Step-by-step explanation:
245 is 100% of the total.
x is 108% of the total.
245/100 = x/108
245(108) = 26460
26460/100 = 264.6
264.6 - 245 = 19.6

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
n = 5m
n = 2/3m - 13
Step 2: Solve for m
Substitution
Substitute in n: 5m = 2/3m - 13Subtract 2/3m on both sides: 13/3m = -13Divide 11/3 on both sides: m = -3Step 3: Solve for n
Define equation: n = 5mSubstitute in m: n = 5(-3)Multiply: n = -15Answer:
Step-by-step explanation:
5m = 2/3m - 13
15m = 2m - 39
13m = -39
m = -3
n = 5(-3)
n = -15

from edge about graphing an absolute value function
determine the domain and range of the function f(x)= -|x| + 2.
the domain of the function is__________
the range of the function is__________
the options are: all real numbers, all numbers greater than or equal to 2, and all numbers less than or equal to 2
Answer:
For the given function f(x)= -|x| + 2
the domain of the function is: All real numbers
the range of the function is: all numbers greater than or equal to 2
Step-by-step explanation:
We need to find the domain and range of the function f(x)= -|x| + 2.
Domain: Domain is defined as all the possible x values of x for which the function is true.
Range: Range is defined as all the possible y values.
So, For the given function f(x)= -|x| + 2
the domain of the function is: All real numbers (the function is true for all real numbers)
the range of the function is: all numbers greater than or equal to 2
(When solving the equation we will have value of f(x) equal or greater than 2)

( 30 points ) last one lol pleasee ?
Answer:
H
Step-by-step explanation:
Answer:
The answer is G because:
the y-intercept is -3 because that's what y is when x is 0
the slope is 2 because the y-values are going up by 6 every time and the x values are going up by 3. slope is rise/run (rise is y because it's axis is vertical and the run is x because it's axis is horizontal) so the slope is 6/3 or simplified to 2.
to write the equation you plug in the values above into the slope intercept form which is:
y = mx + b
where m is the slope and b is the y-intercept
so the answer is y= 2x -3 or G

(1.4 x 105)(2 x 107)
Answer:
31458

147 x 247 = 31,458
a=zm+z solve for m please help!!!!!
Answer:
(a-z)/z = m
Step-by-step explanation:
a = zm+z
Subtract z from each side
a-z = mz+z-z
a-z = mz
Divide by z
(a-z) /z = mz/z
(a-z)/z = m
expand (4x-2) (3x + 1)
Answer: i believe it is 12x²−2x−2
Step-by-step explanation:
(4x−2)(3x+1)
=(4x+−2)(3x+1)
=(4x)(3x)+(4x)(1)+(−2)(3x)+(−2)(1)
=12x²+4x−6x−2
=12x²−2x−2

Find the measure of each missing angle
Angle 21 =
Angle 22 =
Angle 23 =
What is the sum of angles 21,22 and 23?
Answer:
Step-by-step explanation:
Angle 21 is calculated like this:
180 - 70 - 50 = 60 because a line is 180 degrees.
Angle 22 = 50 degrees because it is opposite to the upper angle of 50 degrees.
Angle 23 = 70 degrees because it is also opposite to the upper angle of 70 degrees.
The sum of the angles would be
60 + 50 + 70 = 180 degrees
