Answer:
-28
Step-by-step explanation:
2xy=2(7)(-2)=14(-2)=-28
Answer:
y-5=-3(x-17)
y-5=-3x+51
y=-3x+46
compare with equation
y=mx+c
slope = -3
Step-by-step explanation:
Answer:
k<1
Step-by-step explanation:
1. Add 32 to both sides
-16k-32+32>-48+32
2. Simplify
-16k>-16
3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)
-16k/-16 = k
-16/-16 = 1
You're left with k < 1
Your number line graph should be an open circle at 1 going to the left.
-3, -2.5, -3/4, 1/4, 3.1, 16/5, 6. I can’t see the other numbers, so it’s just these
Answer:
b.
b.
Step-by-step explanation:
scientific notation should have one positive in front of the decimal point, then any number (>=1) of positions after the decimal point, followed by the multiplication with the property power of 10.
the only number not following that rule is b (2 positions in front of the decimal point).
4x - 2y = 6
2x - y = 3
are the same line, as we can multiply the second equation by 2 and get exactly equation 1.
so, both lines have the same slope and the same y-intercept. therefore, they have infinitely many solutions.
