Answer: The correct answer is 8^2 or 64
Step-by-step explanation: Can I please get the brainliest answer.
Answer:
8²
Step-by-step explanation:
When we divide numbers with exponents that have the same bases, we can just subtract the exponents. So, 8^9/8^7 equals 8^(9-7) = 8^2 (Which equals 64, but it isn't a power).
(6y + 10) - (2y + 3)
Answer:
4y+7
Step-by-step explanation:
First, remove the unnecessary parenthesis. Add like terms (In this case it’s y) So it will be 6y-2y. Which gives you 4y. And then after that 10-3, which gives you 7. So your final answer is 4y+7!!

True of flase a point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS
Answer:
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
So what do you think the answer is true or false
Answer:
True
Step-by-step explanation:
That is possible since the x is on 0. It can flip and then it lands on (0,-2) I think.

Your mom sends you to the store to buy some meat for
your birthday party.
She gives you $65 and wants you to spend it all on
exactly 15 pounds of meat.
Chicken is $3 a pound.
Steak is $5 a pound.
Is her request possible? If so, how much of each meat
would satisfy your mom's request?

10 pounds of steak for 5 dollars each = $50
$65 - $50 = $15
5 pounds of chicken for 3 dollars each = $15
$15 - $15 = 0 10 pounds + 5 pounds = 15 pounds
Answer:Yes

What is the mode and range of the data set
18,22,20,21,24
Answer:
There is NO mode.
The range is 6.
Step-by-step explanation:
Mode is the most frequent number and in this case there are no repetitive numbers.
Range is the Max Number minus the Minimum Number. So in this case 24-18 which equals 6.
The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)
Answer:
C.) -5
Step-by-step explanation:
The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.
In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"
To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5
Evaluate f(x)=7x+7 when x=-9
Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56

Find the dimension of a rectangle whose with is 6 miles less than its length and whose area is 72 square tiles
Answer:
Length = 12
Width = 6
Step-by-step explanation:
Width = 6 miles less than length;
L = L
W = L - 6
Area = 72 ft²
Area = Length * width
Area = (L * L-6)
Area = L² - 6L
-
L² - 6L = 72
L² - 6L - 72 = 0
L² - 12L + 6L - 72 = 0
L(L - 12) +6(L - 12) = 0
L = 12 or L = - 6
L cannot be negative
Width = L - 6
Width = 12 - 6 = 6
Hence,
Dimension of rectangle :
Length = 12
Width = 6
