Answer:
(10,0)
Step-by-step explanation:
When it comes to rotations by 90 degrees or 270 degrees, you just have to switch the order of x- and y- coordinates. Then find the sign by considering which quadrant will it be. In this case, it is originally on the positive y-axis and now it would be +ve x-axis.
Answer:
I Think the answer should be (B)
Let me know if its correct.
Step-by-step explanation:
when you average it you only use the final number of the scores for example 94 the last number is 4.
4+6+0+4÷100
= 10.04
Answer:cost of each donut =$4
and cost of each cup of hot chocolate =$2
Step-by-step explanation:
Step 1
Let donuts be represented as d
and cups of hot chocolate be rep as c so that
5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as
5 d+ 2 c= 24
And 2 donuts and 3 cups of hot chocolate costing 14$ will be expressed as
2d +3 c= 14
Step 2
Using elimination method,Multiply equation 1 by 3 and equation 2 by 2
15d+ 6c= 72----equation 3
4d+ 6c= 28-----equation 4
Subtracting equation 4 from equation 3 gives us
11 d=44
d= 44/11
d= 4
To find c, using equation 1
5 d+ 2 c= 24
5 x 4+ 2c=24
20+2c=24
2c=24-20
2c=4
c=4/2 =2
cost of each donut =$4
and cost of each cup of hot chocolate =$2
Rewriting in intercept form
4x+6y= 3 becomes
y= 4x/6 + 3 /6 = ⅔x + ½
it's m = 2/3
for the second line
6x + 9y = 7
y= 6x/9 + 7/9 = ⅔x +7/9
it's m = 2/3
so the two lines are parallel..
100% sure ,
don't forget to give brainliest if correct
