Evaluate the expression when x=10, y=−2, and z=−5. −x2+6z/y=
Answers
- (10)2 + 6(-5)/(-2)
- 20 + -30/-2
- 20 + 16
4 ( I think)
Final answer:
The value of the expression −x2+6z/y when x=10, y=−2, and z=−5 is -85.
Explanation:
To evaluate the expression when x=10, y=−2, and z=−5, we substitute these values into the expression:
−x2+6z/y
−(10)2+6(-5)/(-2)
−100+(-30)/(-2)
−100+15
= -85
Therefore, when x=10, y=−2, and z=−5, the value of the expression −x2+6z/y is -85.

Answer:
f(17) = 48
Step-by-step explanation:
Since f(x) = 3x-3, to find the value of x when f(x) = 48 can be found by substituting 48 for f(x).
48 = 3x - 3
51 = 3x
17 = x
When x is 17, f(x) is 48.
Answer: x=51/3
Step-by-step explanation:
Make f(x)= 48
48=3x-3
Add 3 on each side
51=3x
Divide by 3
51/3
X=51/3

Answer:
y = 8
x = 3
Step-by-step explanation:
5x+y=23
3x+y=17
cancel out the Xs
15x + 3y = 69
-15x - 5y = -85
-2y = -16
y = 8
Plug in 8 for the Y in any of the equations it doesn't matter
3x + y = 17
3x + 8 = 17
3x = 9
x = 3

What is equation of line?
The set of points that make up a line in a coordinate system are represented algebraically by a line's equation.
An equation of a line is an algebraic expression that represents the several points that together make up a line in the coordinate axis as a set of variables, x, and y.
The given term is,
f(x) = 3/2x+2,
Substitute f(x) = y
y=3/2x+2 (1)
Since, the standard form of equation of line is y=mx+c
compare equation (1) which standard equation of line,
m=3/2, and c=2
On the graph of the line the points are, (-1.333, 0) and (0, 2).
