Answer:
y = 18
Step-by-step explanation:
Given
f(x) = 2x² ( substitute x = 3 )
y = f(3) = 2(3²) = 2(9) = 18
Answer:
x = 12/7
Step-by-step explanation:
in order to solve this formula x/4 + x/3 = 1
<u>solutio</u>n
x/4 + x/3 = 1
the first step to do is to take lcm of the left hand side
[3(x) + 4(x)] /12 = 1
[4x +3x]/ 12 = 1
7x/12 = 1
cross multiply
7x/12 = 1
7x = 12 × 1
7x = 12
divide both sides by 7
7x/7 = 12/7
x = 12/7

Equation of this line is K = -2J + 28
<u>Step-by-step explanation:</u>
Step 1:
The equation can be written in slope intercept form which is y = mx + b
Step 2:
Calculate slope of the line, m = (y2 - y1)/(x2 - x1)
⇒ m = (24 - 20)/(2 - 4) = 4/-2) = -2
Step 3:
Find y-intercept of the line
⇒ b = 28
Step 4:
Substitute values in the equation
⇒ K = -2J + 28
