The solution for given equation 4 + 2x - 3 = 4 is
<em><u>Solution:</u></em>
Given that we have to find the answer for the given equation
<em><u>Given equation is:</u></em>
4 + 2x - 3 = 4
Here we have to find the value of "x"
The value of the variable is found by adding, subtracting, multiplying or dividing both sides of the equation to simplify the equation and isolate the variable.
The goal is to have the variable on one side of the equation and numbers on the other.
From given equation,
4 + 2x - 3 = 4
4 - 3 + 2x = 4
1 + 2x = 4
2x = 4 - 1
2x = 3
Thus the solution for given equation is
Answer: y=-3/2x-13/2
Step-by-step explanation:
To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.
3x+2y=9 [subtract both sides by 3x]
2y=-3x+9 [divide both sides by 2]
y=-3/2x+9/2
Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.
-5=-3/2(-1)+b [multiply]
-5=3/2+b [subtract both sides by 3/2]
b=-13/2
Now, we know the equation is y=-3/2x-13/2.
Answer:
Eric rode 2 more miles per week than Kim rode.
Step-by-step explanation:
Find how many miles per week Kim rode by dividing the number of miles she rode by the number of weeks:
135/9
= 15
Find how many miles per week Eric rode:
102/6
= 17
So, Kim rode 15 miles per week and Eric rode 17 miles per week.
The answer is Eric rode 2 more miles per week than Kim rode.
Find the Z score of both:
Z =(X-μ)/σ
Z₁ = (60-80)/10 ==> -2
& Z₂ =(100-80)/10==>+2
& you will find on the Z score tables that the probability to be between
60 & 100 is 0.95 or 95%
Answer:
The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean. To determine the sum of squares, the distance between each data point and the line of best fit is squared and then summed up. The line of best fit will minimize this value.
