The answer is -1.75
Answer:
4x+y=−3
Step-by-step explanation:
simplify −4(x+2).
Apply the distributive property.
y−5=−4x-4⋅2
Multiply −4 by 2.
y−5= --4x−8
Move all terms containing variables to the left side of the equation.
4x+y=−3
Answer:
Friend 1 (with 80 more tickets) gets 290
Friend 2 gets 210
Step-by-step explanation:
500-80 = 420 tickets |
^in order to figure out how many total tickets they got without the 80 extra
420/2 = 210 |
^divide by 2 to figure out how many tickets each friend had
210+80 |
^add 80 to figure out how many tickets friend one gets
<u>210</u><u> </u><u>+</u><u> </u><u>290</u><u> </u><u>=</u><u> </u><u>500</u>
1/2, 8/16, and a lot others.
Answer:
y = -6x + 5
Step-by-step explanation:
Perpendicular to the line:
find reciprocal of slope 1/6 => m= -6
Sub m = -6 and point (-3,23) into equation of a line
y = mx + b
23 = -6(-3) + b
23 = 18 + b
Isolate and find b
b = 5
Sub slope and b to get the equation
