Answer:
Step-by-step explanation:
This is a right angled triangles and the summation of the other two angles must equal 90°
OR you can also say that the summation of all the angles in a ∆ must give us 180°
Therefore (2x+14) + (4x-26) = 90°
Expanding... By collecting all like terms, we have
2x+4x+14-26-90 = 0
6x - 102° = 0
Therefore, 6x = 102
x = 102/6
x = 17°

6.9/10. 78/100. Clueless (1995)
7.2/10. 64/100. We Are Who We Are (2020)
7.0/10. 76/100. Bill & Ted's Excellent Adventure (1989)
8.4/10. 80/100. Euphoria (2019)
5.9/10. 71/100. She's All That (1999)
Step-by-step explanation:
The answer is A.
The way you know this is by graphing the first function.
The second function is in a different format, so you just have to isolate Y.
-1/3x + y = -1
y= 1/3x -1 OR y= -1 + 1/3x
both of the functions have the same slope, but different y-intercepts. therefore, they'll never touch. making them infinite solutions.
it's also A because both of the slopes are positive, the slopes in graph D are negative.
So, the answer is A.

This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.
