Answer:
Step-by-step explanation:
Part A
2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections
PART B
y=1/3x^2 and y= 2/3x - 5
1/3x^2 = 2/3x-5
1/3x^2=2/3x-5
then u multiply everything by 3
1/3x^2*3 =2/3x *3-5*3
the three for 1/3*3 cancels out so you are left with
1x^2= 2x -15
1x^2-2x+15=0
You can not factor it and well i guess there is no intersection
im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b
Answer:
x=sqrt of 12
Step-by-step explanation:
First, you divide by 9 on both sides:
x^2= 108/9
Then you solve that:
x^2 = 12
Then you find the root of both sides:
sqrt (x^2)= sqrt (12)
and you get:
x= sqrt of 12 which is about 3.46... OR 2√3
We know that :
From the figure, We can notice that :
Ф Adjacent side length = 8
Ф Hypotenuse length = 11
Answer:
12/(n-1)=10/(n+3). 12n−1=10n+3 12 n - 1 = 10 n + 3
