Answer:
x= -5
y= -2
Step-by-step explanation:
From the equation y=x+3-------eqn 1
x+y= -7-------eqn2
x+(x+3)= -7 (since there is no value before the bracket is 1, so multiply by 1)
x+x+3= -7
2x+3=-7
2x=-7-3
2x=-10
x=-10/2
x=-5
Insert x value in equation 1
y= -5+3
y=-2
(a)
The unknown information is the amount of potting soil Emmanuel bought last week.
(b)
40 lb of potting soil is 4 lb more than 3 times p (the amount of potting soil he bought last week).
The equation:
(c)
The solution to the equation is 12.
(d)
Last week Emmanuel bought 12 lb of potting soil.
Answer:
The solution is (5 , 1)
Step-by-step explanation:
I'm not sure if this is a trick question, but the definition of a linear function prevents the function from having more than one y-intercept. x-values can't be shared in a function; there is a unique x value for every y value. at the y-axis, the value of x is 0. two y-intercepts would mean that x would be 0 for TWO points on the linear function, which doesn't pass the vertical line test and, therefore, isn't a function.
a graph CAN, however, have more than one x-intercept. the line y = 0, which passes the vertical line test and sits directly on top of the x-axis, has infinitely many x-intercepts and it is still a linear function.
If the bottom number is the same thing as 1 then it will be 1, if not, then it will be a mixed fraction
