Answer:
The slope is -1
Y-intercept is (0, -6)
Equation is y = -1x - 6 or y = -x - 6 either is right
Step-by-step explanation:
We already know that the slope is negative because the line is pointed this way \ pointed up to the left.
You have to do rise/run to find the slope.
The rise is 6 and the run is 6
6/6 = 1 since the line is negative the slope is -1x or -x
The y intercept is -6
Use the point (-2, -4)
Plug in
-4 = -(-2) + b
-4 = 2 + b (subtract 2 on both sides)
-6 = b
y = -x - 6
Hope this helps ya!!
Answer:
g(f(x)) = 2x - 2
Step-by-step explanation:
to evaluate g(f(x)) substitute x = f(x) into g(x)
g(f(x)) = g(2x + 1) = 2x + 1 - 3 = 2x - 2
Answer: $11.30 per pound
Step-by-step explanation:
William spent $110.74 to buy 9.8 pounds of candy.
To find the cost per candy, divide the amount spent by the quantity of candy:
=Amount spent on candy / Quantity of candy
= 110.74 / 9.8
= $11.30 per pound
Answer:
Step-by-step explanation:
-5x-4y=-4 ...(1)
25x+ 20y = 20 ....(2)
multiply (1) by -5 you have : 25x+ 20y = 20 ....(2) same equation , same line
so : The system has infinitely solutions.
Answer:
The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)
Step-by-step explanation:
b=(6,3)
c=(-4,8)
a=2b+c
Replacing b and c in the equation above:
a=2(6,3)+(-4,8)
Multiplying:
a=(2*6,2*3)+(-4,8)
a=(12,6)+(-4,8)
Adding:
a=(12+(-4),6+8)
a=(12-4,14)
a=(8,14)
