Answer with Step-by-step explanation:
If two lines on the same plane have different slopes, they are intersecting lines.
If two equations can be transformed to one form and they are equal, they are coinciding lines.
for parallel lines their slope (m) must be equal and their y-intercept (b) must be different.(y=mx+b)
-3x + 5y = 22 (equation 1) or 5y=22+3x
or
20y − 11 = 12x (equation 2)
or 20y=12x+11
Hence, we can see clearly the two lines have same slope 3/5 but y intercept is different
So, two lines are parallel
Hence, Correct option is:
c. parallel lines
We have been given a table that shows a linear relationship between x and y. We are asked to find the rate of change change of y with respect to x.
To solve our given problem, we will find the slope of the line passing through the given points.
Let us find slope of line using points and
.
Therefore, the rate of change of y with respect to x is .
let me edit your question as:
Which two equations are true?
<u>Eq1:</u>
(2×10−4)+(1.5×10−4)=3.5×10−4(3×10−5)+(2.2×10−5)
<u>Eq2:</u>
6.6×10−10(6.3×10−1)−(2.1×10−1)=3×10−1(5.4×103)−(2.7×103)
<u>Eq3:</u>
2.7×103(7.5×106)−(2.5×106)=5×100
Answer:
No one is true
Step-by-step explanation:
let's check each equation, if the values on both sides (left and right side) are equal then the equation is true otherwise false.
Using PEMDAS rule we are simplifying the equations as;
<u>Eq1:</u>
<u>Eq2:</u>
<u></u><u></u>
<u>Eq3:</u>
<u>we observed that none of the equation has two same values on both sides thus none of the three equations is true.</u>
<u>Also, no value of Eq1, Eq2 or Eq3 are same thus none of the equation is true</u>
