Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation for the given phrase is 10+x=-13 and the solution is x=-23.
The given phrase is "The sum of 10 and x is -13".
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Here, the sum of 10 and x is 10+x.
Now, the equation is 10+x=-13
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The solution is x=-13-10 (Transpose 10 to other side of the equation)
x=-23
Therefore, the equation for the given phrase is 10+x=-13 and the solution is x=-23.

in the bank until it reaches 9600 dollars?
Answer:
14.4
Step-by-step explanation:
Given that :
Principal = 4000
Interest (r) = 6.25% compounded annually
Calculate time, t, if final amount A = 9600
Using the compound interest formula :
A = P(1 + r/n)^n*t
A = final amount
n = number of times interest is applied per period
9600 = 4000(1 + 0.0625)^t
9600 = 4000(1.0625)^t
9600/4000 = 1.0625^t
2.4 = 1.0625^t
Take the log of both sides
0.3802112 = 0.0263289t
t = 0.3802112/0.0263289
t = 14.440811
t = 14.4 ( nearest tenth)

Answer:
perpendicular
Step-by-step explanation:
it is perpendicular because you flipped and negative the slope. if it was parallel the slope would be the same with no negative

Step-by-step explanation:
Answer:
x = -2
y = -3
Step-by-step explanation:
We can use either substitution or elimination for this problem. I will use elimination to solve this problem:
Step 1: Eliminate x by adding the 2 equations together
9y = -27
y = -3
Step 2: Plug in y into one of the original equations to get x
-9x + 4(-3) = 6
-9x -12 = 6
-9x = 18
x = 2
And we have our final answers!
