Answer:
a. the answer is incorrect
b. 1
Step-by-step explanation:
step 1) 6x=48
step 2) 48/6
step 3)x=3
For a) you would start at positive 4 then go up 2 then right 2 and repeat that
I believe it is 58 for the answer
Answer:
Tess = 71 y/o
Nina = 63 y/o
Katy = 55 y/o
Step-by-step explanation:
First step: divide their age equally.
189÷3 = 63 years old / person
Second step: calculate the different between their age.
Tess>Nina>Katy
Different between:
Katy and Tess
= 16 years
Nina and Katy
= 8 years
Tess and Nina
= 16–8
= 8 years
Third step: Calculate their age.
Tess = 63+8
= 71 years old (because she is 8 years older than Nina and 16 years older than Katy)
Nina = 63 years old ( it doesn't change because she is in the middle)
Katy = 63–8
= 55 years old (because she is 8 years younger than Nina and 16 years younger than Tess)
To confirm, you can sum their age and check the age differences like what have been told in the question either it is correct or not.
71+63+55
= 189 years
Y = mx + b....m is the slope and b is the y intercept
slope(m) = 5...(4,0)...x = 4 and y = 0
now we sub our info into y = mx + b...we r looking for b, the y intercept
0 = 5(4) + b
0 = 20 + b
-20 = b
so ur equation is y = 20x - 20...but we need it in standard form
Ax + By = C
y = 20x - 20....subtract 20x from both sides
-20x + y = -20...multiply by -1 to make x positive
20x - y = 20 <== standard form
