I think the answer it’s c
Answer:
The correct answer is The function is a direct variation function with a constant of variation 1.5
Step-by-step explanation:
One way to see if this is a linear function is to see by how much the x and y increase each time:
x | y
10 | 18
14 | 24
18 | 30
X is increasing by 4 each time, and y is increasing by 6. This is a linear function. Divide the y by the x to get the slope.
6 ÷ 4 = 1.5
This is a linear function and its slope is 1.5.
Hope this helps,
1. y=mx+b
y=-1/4x-1
2. y=mx+b
y=3.5/2.5x+4
Answer:
x =
Step-by-step explanation:
Given
= - 4
Multiply both sides by 5
3ax - n = - 20 ( add n to both sides )
3ax = - 20 + n = n - 20
Isolate x by dividing both sides by 3a
x =
1) Simplify : - 4x + 3(2x + 5) - 3x + 12
breaking 3(2x + 5) we get,
Now, as per the PEMDAS rule let's shorten the like terms
<u>Correct option is C i.e. - x + 27</u>
2) Simplify : 3x + 3(x + 6) - 4 - 5x
breaking 3(x + 6) we get,
Again using the same rule we see,
<u>Correct answer is option C i.e. x + 14</u>
3) Expression : y[x² - 2(1 + 2)] ÷ y + 5²
In this case we are given that <em>x = 3</em> whereas <em>y = 7</em>
Putting the values of x and y we see,
<u>Henceforth, the final answer is 28</u>
