=k+2,b

=3k+2.
Therefore, the given system of equations will have infinitely many solutions, if
k+2

⇒
k+2

=

and

=

4
⇒
k+2

=

and
2

=
3k+2
4
⇒k+2=4 and 3k+2=8
⇒k=2 and k=2
⇒k=2
Hence, the given system of equations will have infinitely many solutions, if k=2.

plz sent with the equation right now plz plz
Answer:
The answer is 0.04a² - 0.04ab - 0.15b²
Step-by-step explanation:
(0.2a - 0.5b) ( 0.2a + 0.3b)
0.04a² + 0.06ab - 0.1ba - 0.15b²
0.04a² + 0.06ab - 0.1ab - 0.15b²
0.04a² - 0.04ab - 0.15b²
Thus, The answer is
0.04a² - 0.04ab - 0.15b²

i need hlep on this pls
It's not a typo that both answers are 24
======================================================
Explanation:
Each time the weight goes up by 1 ounce, the cost goes up by 24 cents. So the unit cost is 24 cents per ounce. This is exactly the slope of the line because the slope is the rate of change. It tells us how fast something is changing.
You can use the slope formula to answer this question, but I think it's easier to simply locate the point (1,24) and then note that slope = rise/run = y/x = 24/1 = 24. This shortcut only works because the line goes through the origin.
The equation of this line is y = 24x
x = number of ounces
y = cost in cents
Step-by-step explanation:both are 24
Solve this
3x + 2 = 26
Answer:
x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
Undo what is done to x. We see that x is multiplied by 3 and then 2 added. We undo these steps in reverse order.
3x +2 = 26 . . . . . . given
3x = 24 . . . . . . . . . subtract 2 from both sides of the equation
x = 8 . . . . . . . . . . . divide both sides of the equation by 3

Buffalo Bart’s Endless Wings charges $5.60 for sides and a drink, and then $0.40 per chicken wing. The Spicy Chicken charges $10 for sides and a drink, and then $0.20 per chicken wing. About how many chicken wings must be purchased so that the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken is the same?
Answer:
22.
Step-by-step explanation:
About 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.
Let's represent the number of chicken wings as "x".
The total cost at Buffalo Bart’s Endless Wings would be the sum of the initial cost for sides and a drink ($5.60) and the cost per chicken wing ($0.40 per wing times x):
Total cost at Buffalo Bart’s Endless Wings = $5.60 + $0.40x
The total cost at The Spicy Chicken would be the sum of the initial cost for sides and a drink ($10) and the cost per chicken wing ($0.20 per wing times x):
Total cost at The Spicy Chicken = $10 + $0.20x
To find the number of chicken wings where the total costs are the same, we'll set up an equation:
$5.60 + $0.40x = $10 + $0.20x
Now, solve for "x":
$0.40x - $0.20x = $10 - $5.60
$0.20x = $4.40
Divide both sides by $0.20:
x = $4.40 / $0.20
x = 22
So, about 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.

Describe and correct the error
|-13|-|13|
=-13-13
=-26
Answer:
The error is that the question equals -13-13.
Step-by-step explanation:
This is absolute value, so anything inside of the bars is positive. Since the first -13 has bars around it it would be positive. But since the second - is outside of the 13 with bars, the 13 stays negative, so it would be 13-13. Hope this helps! :)

How to include a negitive number (s) in a math problem
Answer:
Adding a negative number is the same as subtracting a positive number — that is, go down (to the left) on the number line. This rule works regardless of whether you start with a positive or negative number.
Step-by-step explanation:
Solve f(x) >0
F(x)= (x-1)(x+3)^2
AnSolve f(x) >0
F(x)= (x-1)(x+3)^2
Solve f(x) >0
F(x)= (x-1)(x+3)^2
Solve f(x) >0
F(x)= (x-1)(x+3)^2
