Step-by-step explanation:
3x - x = 2x
2(x + 2) = 2x + 2
for every number of x, 2x + 2 would always be larger than 2x.
so there is no solution, since the given equation is 2x is greater than 2x + 2.
Answer: 50%
Step-by-step explanation:
If we can get a head tails combo in any order we could get a head/tails or a tails/head so there is a 50% probability of getting that combo in a trial
Well you can do it manually or use a calculator.
Answer is 98.66074
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
9x+7y=4
7y = - 9x + 4
y = -9x/7 + 4/7
Comparing with the slope intercept form, slope = - 9/7
If the line passing through the given point is perpendicular to the given line, it means its slope is the negative reciprocal of the slope of the given line.
Therefore, the slope of the line passing through (7,-4) is 7/9
To determine the intercept, we would substitute m = 7/9, x = 7 and y = -4 into y = mx + c. It becomes
- 4 = 7/9×7 + c = 49/9 + c
c = - 4 - 49/9 = -85/9
The equation becomes
y = 7x/9 - 85/9
