Answer:
B
Step-by-step explanation:
y=x+2. let it eq 1
put y= - 2 and x=-4 in eq 1
-2 = -4+2
-2= -2
now put x= -3 and y= -1 in eq 1
-1 = -3+2
-1 =-1
now put x= -2 and y=0 in eq 1
0 = -2+2
0=0
now put x= -1 and y=1 in eq 1
1 = -1+2
1=1
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
What specifically do you need help with? range is the y-values and domain is the x-values. so if you write down each point you’ll have domain and range.... comment what else i can help with?
Answer:600 miles apart
Step-by-step explanation: one inch is 100 miles multiply that by 6 you get 600 miles
Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
