Answer:
x = -1, y= -5
Step-by-step explanation:
y=-x-6
y=x-4
Since both equations are equal to y we can set them equal to each other
-x-6 = x-4
Add x to each side
-x-6+x = x-4+x
-6 = 2x-4
Add 4 to each side
-6+4 = 2x-4+4
-2 =2x
Divide by 2
-2/2 = 2x/2
-1 = x
now find y
y = x-4
y = -1-4
y = -5
Answer:
y=x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-1)/(5-1)=4/4=1
slope is 1
y-y1=m(x-x1) where m=slope
y-1=1(x-1)
y-1=x-1
y=x-1+1
y=x
Answer:
1: she used the wrong formula
2: 36cubic feet
3: the strategy: knowing that to find the volume of a rectagle is l*w*h and subtituting in the correct numbers
Step-by-step explanation:
1: to find the volume of a rectangle is height*width*length
2: you multiply 6*5*1.2 and you should get 36 and sice you are finding volume it is cubic and the measurment
Answer:
on the x axis because it is reflected there
1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..

I'll do the others in a different answer!!
