We analyze the linear function to find that it has equation
. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting into the given equation:
Hence,
or
, so there are both positive and negative values for
.
Answer:
y < x - 4
Step-by-step explanation:
First, move the x over to the other side by subtracting x from both sides. This will get you -y > -x + 4.
Divide both sides by -1 to get rid of the -1 in front of y. Since this is an inequality, dividing or multiplying by a negative number means that you have to flip the sign. We are dividing by a negative number, so flip > to <. The signs on both sides change to get y < x - 4.
A is 3 (5) + 4 (0)>24 this is false because 3 times 5 equals 15 plus 4 time 0 which is 0 is 15 and 15 is less than 24 not greater than 24
A. IS FALSE
b is 3 (4) + 4 (3)>24 this is false because 3 times 4 equals 12 and 4 times three equals 12
12 plus 12 equals 24 and 24 is equaled to 24 not greater than
B IS FALSE
c is 3 (-2)+4(9)>24
3 times -2 is -6 plus 4 times 9 which is 36 is 30 30 is greater than 24 so
C IS TRUE
17.99 + 0.83m = 140
0.83m = 140 - 17.99
0.83m = 122.01
m = 122.01 / 0.83
m = 147 <== Mike drove 147 miles
8x+8y=240
First, make the coefficient of y to be 1.
x+y=30
Then, subtract x on both sides.
y=30-x
Rearrange it if you want.
y=-x+30
