Answer:
Step-by-step explanation:
We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).
So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).
The slope formula is given by:
So, by substitution, our slope is:
Now, we can use the point-slope form:
By substitution:
Distribute:
Adding 4 to both sides yields:
And we have our equation.
In this case, the y-intercept is 0.
To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the area of a rectangle:
2. Now, you must solve for the width:
Therefore, the answer is:
Answer:
x = 4
Step-by-step explanation:
Step 1: Write out equation
3x + 6 = 18
Step 2: Subtract 6 on both sides
3x = 12
Step 3: Divide both sides by 3
x = 4
Answer:
Option C is correct.
The solution is (3, -1)
Step-by-step explanation:
Substitution
Given the system of equation:
......[1]
......[2]
We can write equation [2] as;
d = e +4 ....[3]
Using substitution method;
Substitute the value of d in equation [1] we have;
Combine like terms;
Subtract 4 from both sides, we get
2e = -2
Divide both sides by 2 we get;
e = -1
Substitute the value of e = -1 in [1] we have;
d +(-1) = 2
d -1 = 2
Add 1 to both sides of an equation;
d = 3
Therefore, the solution for the given system of equation is, (3, -1)
75 percent is 12 which is 3/4 so make a proportion .75/12 = 1/x cross multiiply and you get 16
