Answer: a) = 10
b) = 16
Step-by-step explanation:
a) as x = 5 so putting the value of x in given equation
5 multiplied by 2 is equal to 10
b) Putting value of x in given equation
= (5 + 3) 2
According to BODMAS solve the brackets first
= 8 x 2
= 16

Answer:
(x, y) = (4, -4)
Step-by-step explanation:
A graphing calculator makes graphing very easy. The attachment shows the solution to be (x, y) = (4, -4).
__
The equations are in slope-intercept form, so it is convenient to start from the y-intercept and use the slope (rise/run) to find additional points on the line.
The first line can be drawn by staring at (0, -2) and moving down 1 grid unit for each 2 to the right.
The second line can be drawn by starting at (0, 2) and moving down 3 grid units for each 2 to the right.
The point of intersection of the lines, (4, -4), is the solution to the system of equations.
Answer:
169
Step-by-step explanation:
Square root means what number times its self is a different number. In this case, 13 times 13 = 169 so 13 times itself is 169.
Answer:
2
Step-by-step explanation:
The degree of a function is the highest power any single term is raised to.
x^2 is the term that has the highest degree, so in this case, the degree is 2.
For example; in x^5-x^4-3x^3; the degree would be 5 because the highest power x is raised to is 5.
