Answer:
undefined
Step-by-step explanation:
The x value does not change, which means it is a vertical line
Vertical lines have an undefined slope
we can check using
m = (y2-y1)/(x2-x1)
=(2- -2)/( -3 - -3)
= (2+2)/( -3+3)
4/0

Answer:
3q + 2p
Step-by-step explanation:
q + p + q + p + q = 3q + 2p
Answer:
(4,7), (-1,12)
Step-by-step explanation:
I will solve using elimination by subtracting one equation from the other.
y = x² - 4x + 7
- y = -x + 11
__________
0 = x² - 3x -4
0 = (x - 4)(x + 1)
x = 4, x = -1
We can plug in these values to get the corresponding y -values.
The solutions should be : (4,7), (-1,12)
Answer:
14
Explanation:
The given triangle is a right-angled triangle. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
Now, we have:
θ = 40°
opposite = 12 m
adjacent is the distance we want to find
Substitute with the givens in the tan formula to get the distance as follows:
tan (40) = 12 / distance
distance = 12 / tan (40)
distance = 14.3 which is approximately 14 m
Hope this helps :)
<em>Note:</em>
<em>Your questions sound a little unclear.</em>
<em>But, I am assuming your questions as:</em>
<em>''70% of x is 14 min. Find the value of x''.</em>
<em>So, I will solve assuming this statement which anyways would clear your concept. </em>
Answer:
The value of x = 20.
Step-by-step explanation:
Given
<em>''70% of x is 14 min. Find the value of x''.</em>
Thus,
70% of x = 14
70/100 × x = 14
0.7x = 14
divide both sides by 0.7
0.7x/0.7 = 14/0.7
x = 20
Therefore, we conclude that the value of x = 20.
