Answer:
(x, y) = (0, -1)
Step-by-step explanation:
The coefficients of x are opposites, so we can eliminate x by adding the two equations.
(6x +y) +(-6x -4y) = (-1) +(4)
-3y = 3 . . . . simplify
y = -1 . . . . . . divide by -3
Now, we need to find x.
6x -1 = -1 . . . substitute for y in the first equation
6x = 0 . . . . . add 1
x = 0 . . . . . . divide by 6
The solution is (x, y) = (0, -1).
Answer:
64/27
Step-by-step explanation:
(4/3)^3=(4/3)*(4/3)*(4/3)=64/27
The missing value for the coordinate pair that lies on the graph of the function. y=5^x (2, 25)
<h3>How to determine the missing values?</h3>
The equation of the function is given as:
y = 5^x
And the x value is given as
x = 2
To determine the missing value, we start by substituting 2 for x in the function y = 5^x
So, we have:
y = 5^2
Evaluate the exponent
y = 25
So, the complete coordinate is (2, 25)
Hence, the missing value for the coordinate pair that lies on the graph of the function. y=5^x (2, 25)

Answer:
£1.22
Step-by-step explanation:
Total cost: 5.95+1.62+0.25+2(0.48)=8.78
Change: 10-8.78=1.22
That's true! Example: a 60-60-60 degree triangle has 3 acute angles.
