Basically f(x)=5x means whatever number you plug in will be your x coordinate, and the result will be your y coordinate.
(1,5) (2,10) (3,15) (4,20) and so on. 1,2,3 and 4 are x coordinates plugged into the equation, the y coordinate is whatever 1,2,3 and 4 multiplied by 5 is.
Answer:
Yes to both.
Step-by-step explanation:
It is true that

In fact, if you know that x/y=1, just multiply both sides by y to get x=y. On the other hand, if you know that x=y (and they are not zero), you can divide both sides by y to get x/y=1.
Since the two expressions are equivalent, you can always use Phil's or Don's expression, at will.
Answer:
The answer is H or J either those two and I'm sure of it.
Step-by-step explanation:
;)
Obtuse I think because 50+40+11=101
Answer:
The value of x = 5 and y = 2
The correct answer is last option
Step-by-step explanation:
From the figure we can see that, subtraction of two matrices.
The resultant matrix shows the corresponding terms difference.
<u>To find the value of x</u>
1/2(x + 3) - (3*(-1)) = 7
x/2 + 3/2 +3 = 7
x/2 +3/2 = 7 - 3 = 4
x + 3 = 8
x = 8 - 3 = 5
x = 5
<u>To find the value of y</u>
8/2 -3 (y +1) = -5
4 - 3(y +1)/ = -5
3(y +1) = 4 + 5 = 9
y + 1 = 9 / 3 = 3
y = 3 - 1 = 2
Therefore the value of x = 5 and y = 2
