What is the solution to x 3 + x 2 ≤ 10x – 8?
Answer:
Solution: x ⩾ \frac{8}{5}
Step-by-step explanation:
x 3 + x 2 ≤ 10x – 8
Reorder the terms
3x + 2x ≤ 10x - 8
Collect like terms
5x ≤ 10x - 8
Move the variable to the left
5x -10x ≤ -8
Collect like terms
-5x ≤ - 8
Divide both sides
x ⩾ \frac{8}{5}

What is the rate if change for y = x - 4
Answer:
The rate of change is 1
Step-by-step explanation:
This is because the slope is x, and -4 is just the y-intercept, which has nothing to do with the slope. Because the slope is x, that means that it is positive 1.
Answer:
Rate of Change = 1
Step-by-step explanation:
Rate of Change = Slope = m
y = mx + b
y = (1)x -4
m = 1

Test this claim at the alpha of 0.02 by calculating the z-score and comparing it to the critical z-score (z subscript c r i t end subscript equals negative 2.05 right parenthesis.

The perimeter of rectangle is 48 cm. Find the sides of the rectangle if one of the sides is 12 cm longer than the other.
Answer:
L=W+12
2L+2W=48
2(W+12)+2W=48
2W+24+2W=48
4W=48-24
4W=24
W=24/4
W=6 ANS. FOR THE WIDTH.
L=6+12=18 ANS. FOR THE LENGTH.
PROOF:
2*18+2*6=48
36+12=48
48=48
Answer:
6 cm by 18 cm
Step-by-step explanation:
use x and x+12
2(x) + 2(x+12)=48
2x +2x+24=48
4x+24=48
4x=24
x=6 and (6+12)=18

d
The time it takes to use a 5 lb bag of dry cat food and the number of cats, if each cat eats the same amount of food per same time interval.
Answer:
I believe the answer is D
Step-by-step explanation:
Inverse proportion occurs when one value increases and the other decreases
D is the answer because as each cat eats the same amount of dry cat food, there is less dry cat food in the bag; so this is why D best answers the question.
Hope this helps!
Answer:
a is false, B is true,
Step-by-step explanation:A is false because the more hours you work, the more money you get.
B is true because if the volume is constant, the bigger the length, the smaller the width, or vice versa.

How many times do you need to regroup to add 873 + 465 ? Explain .
Answer:
2
Step-by-step explanation:
To find the answer to this question, we need to add the numbers according to their place. Etc if 1 and 4 are together in a hundreds place, we add them together. If both numbers add up together results in a number bigger than 9, we have to regroup.
First, let us find the ones place.
3+5=8
Since the result is not more than 9, we do not have to regroup.
Secondly, we find the tens place.
7+6=13
Since the result is more than 9, we have to regroup.
Regrouping counter:1
Thirdly, we find the hundreds place.
8+4=12
Regrouping counter:2
Hence, your final answer is 2.
The number of times we need to group when summing 873 and 465 is 2.
During addition of two numbers, values are added based on their place values, such that digits with the same place value are added together.
The highest single value that can be obtained when summing values without needing to regroup is 9.
Hence, each time two digits are added such that the value of the sum exceeds 9, then regrouping is required.
Adding 873 + 465
H __ T __ U
8 __ 7 __ 3
4 __ 6 __ 5
(3 + 5) = 8 ( NO NEED TO REGROUP)
7 + 6 = 13 (WE NEED TO REGROUP) SUM exceed 9
(8 + 4 + 1) = 13 (WE NEED TO REGROUP) SUM exceed 9
Hence, the number of times we need to regroup is 2.

This is because if you do 303+60=363 and then you do 363/11 you get 33. So x=60
60
Step-by-step explanation:Multiply both sides of the equation by 11:
303 + x =363
Move constant to the right side and change its sign:
x = 363 - 303
Then,subtract the numbers:
x = 60

Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{ - 2 + 3}{8 - 4} [/tex]
