A, E
Did the math to find the solution earlier, got right xoxo :)
The correct Option is (D) <span>y = -0.15x + 1.95
Explanation:
The linear (line) equation is:
y = mx + c
Where
m = slope = rise/run = -0.3/2 = -0.15 (negative sign indicates the downward slope)
c = y-intercept = 1.95 (in graph)
Plug in the values in line equation:
y = -0.15x + 1.95 (Option D)</span>
Answer:
82.31
Step-by-step explanation:
I believe this is correct, if it isn't feel free to let me know and I will fix it. I'm sorry in advance if this is incorrect.
X=number of boys.
y=number of girls.
we suggest this system of equation
x/y=9/7
x=y+116
We solve this system of equation by substitution method.
(y+116)/y=9/7
7(y+116)=9y
7y+812=9y
9y-7y=812
2y=812
y=812/2=406
x=y+116
x=406+116=522
answer: At the school there are 522 boys and 406 girls.
to chek.
522/406=1.2857...
9/7=1.2857...
The number of boys (522) is equal to 406+116=522.
Answer:
20 units squared
Step-by-step explanation:
Use pythagorean theorem to find third side of triangle
Take the sqr root of 20
So the side of the square is sqr root of 20
Area is length x width
The area of a square is 2 times s, where s is the length of one side since a square sides are all equal.
So
