Answer:
2x - 5 if x ≤ 2
f(-1) = -7
Step-by-step explanation:
x ≤ 2 = (-1) ≤ 2
x > 2 = (-1) > 2
2x - 5
2(-1) - 5
-2 - 5
-7
Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5

What does n represents
In arithmetic, the number that divides another is referred to as divisor;
Take for instance;
This implies that when 5 is divided by 3, the remainder is 2
The bold text (divided by 3) means that 3 is the divisor of 5;
When compared to
We have that
n = 3
<em>Reason being that, n and 3 are in the same position base on order of appearance;</em>
Hence, n represents the divisor
Answer:
d. vertical line
Step-by-step explanation:
A line with an undefined slope is a vertical line
Slope is the change in y over the change in x
When the slope is undefined, it means that the x does not change, which is a vertical line
