Im pretty sure it’s B because it tells your the area which is 40 and the length which is 4. I don’t know how to explain it but hopefully it kinda of helped and it’s right.
Answer:
t = 115
s = 60
g(x) = 10/23x - 10
Step-by-step explanation:
find s first since its easy (it goes up by 10's)
then take a pair from the table that corresponds such as 69 for x and 30 for g(x) and turn them into a fraction:
69/30
do the same for t:
t/50
equal 69/30 to t/50 and solve using cross multiplication:
69/30 = t/50 =
30t = 3450
/30 /30
t = 115
honestly had a little hard time finding the equation but basically I simplified the fraction 30/69 to get 10/23 for slope and then I insert a corresponding x and y value into y= mx+b with the slope value to find b.
Answer:
y=8 x=-6
Step-by-step explanation:
line them up
3x+10y=22
-3x-8y=-14
add the like terms to get
2y=8
divide by 2
y=4
plug in to any equation
3x+10(4)=22
3x+40=22
subtract 40
3x=-18
divide
x=-6
Answer:
B)
Step-by-step explanation:
-3x, and 7(x-4) are all terms.
