Answer:
x intercept = -0.25
y intercept = 4
Step-by-step explanation:
1.- remove parenthesis
y-3 = 1/2x +1
2.- adjust to equal y
y = 1/2x +1 +3
y = 1/2x +4
3.- guess values for x to try in the simplified equation.
x = -0.25 | y = 0
x = 0 | y = 4
x = 2 | y = 5
x = -2 | y = 3
x = 4 | y = 6
x = -4 | y = 2
4.- graph all coordinates (x,y). Draw a line connecting each dotted coordinate.
Answer:
Step-by-step explanation:
2x+3+2x-12+4x-11=180 degree (sum of interior angles of a triangle)
8x-20=180
8x=180+20
x=200/8
x=25
Now , substitute the value of x.
Chicago=2x+3
=2*25+3
=50+3
=53 degree
Austin=2x-12
=2*25-12
=50-12
=38 degree
Atlanta=4x-11
=4*25-11
=100-11
=89 degree
Answer:
C
Step-by-step explanation:
well first you want to multiply 3.5 times 2.99 which gives you 10.465 and you round that it should be 10.47
Answer: She worked as a carpenter for 12 hours and a blacksmith for 18 hours.
Step-by-step explanation:
