Answer:
x=9
Step-by-step explanation:
Step 1: Subtract 10 from both sides.
2x+10−10=28−10
2x=18
Step 2: Divide both sides by 2.
2x /2 = 18 /2
Expand: f(x) = x4 − x3 + x2 + x −

How much would a man who weighs 50 pounds on the moon weigh on Earth?
Find the slope of the line passing through the points (-6, 2) and (-6, -1).
Answer:
3/0
Step-by-step explanation:
to find the slope use rise over run or y-y/x-x, in this case, 2-(-1)/-6-(-6)the negative and the subtraction sign cancel out resulting in something like this: 2+1/-6+6 equaling 3/0
I hope this helps have a nice day
In scientific notation
Jenifer bought 6 packages of hotdogs and 8 packages of rolls for $41.50. A package of rolls cost $0.85 less than a package of hotdogs. How much did each package of hotdogs cost?
Answer:
hotdogs 3.45
rolls 2.60
Step-by-step explanation:
6h + 8r = 41.5
r=h-.85
6h + 8(h-.85)=41.5
6h + 8h - 6.8 = 41.5
14h = 41.5 + 6.8
14h = 48.3
h=48.3/14
h=3.45
r=3.45-.85=2.6

A square board was attached to a wall. The board was divided by four squares and each square was colored either black or white. How many possible combinations of such coloring are there, if we cannot rotate the given board? PLEASE HELP QUICK! IM NEW AND I NEED ANSWERES! I HOPE BRAINLY DEOS NOT FAIL ME!
Answer:
24 combinations
Step-by-step explanation:
For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.
Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)
By the way, welcome to brainly.

Determine the slope of the table
A)2
B)5
C)-0.5
D)0.5
Answer:
C) -0.5
Step-by-step explanation:
Since the y₁ is decreasing, that automatically makes it a negative slope, and its decreasing by 0.5, so it's C!
plz help me I need it
b = 92 degrees (choice B)
c = 92 degrees (choice D)
d = 92 degrees (choice F)
================================================
Explanation:
Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180
a+b = 180
88+b = 180 ... plug in a = 88
b = 180-88 ... subtract 88 from both sides
b = 92
------------
Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.
Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.
Since b = 92, this means c = 92 and d = 92 also.

What is the slope of this graph
Plz help with graph polynomial
Answer:
(x + 1 ) is a factor
Step-by-step explanation:
Given a polynomial with roots x = a, x = b , then the corresponding factors are
(x - a) and (x - b)
From the graph
The roots are x = - 1 and x = 4 , thus factors are
(x - (- 1)) and (x - 4) , that is
(x + 1) and (x - 4)
(x + 1) is the required factor
What is the slope of this line?
Give your answer as a fraction in simplest terms.
Answer:

Here are ten numbers 3, 7, 2, 4, 7, 5, 7, 1, 8, 8, what is the mode, median, range and mean
3,7,2,4,7,5,7,1,8,8
Step-by-step explanation:
The median is the middle. You add and divide for the mean. The mode is the one that appears the most. And the range is the difference in between.
Answer:
Mode = 7
Median = 6
Range = 7
Mean = 5.2

6c + 2c = 8c
-1 + 11 = 10
Final: 8c + 10
what is the slope of the line on the graph?
Answer:
Step-by-step explanation:
So you need to take two points off the graph. (x,y) and (x,y)
After that use those points to plug it into this equation
your gonna want to take the Y points from both and subtract from each other.
Do the same for the X points.
Y2-Y1
X2-X1
You'll then divide The Y by the X and that the Rise over Run. When you graph that. That'll be your answer.
