Answer:
ok so the first one is
1200x+2000
the second one is
1000x+3000
month 1.
a.3200
b.4000
month 2.
a.4400
b.5000
month 3.
a.5600
b.6000
month 4.
a. 6800
b. 7000
month 5.
a. 8000
b. 8000
They would equal out at 8000 in month 5
Answer:
98 or 18
Step-by-step explanation:
Let's call the numbers 3x and 7x. We have two cases, either 42 is 3x or 42 is 7x. Looking at the first case, if 3x = 42, x = 14 which means the other number is 7 * 14 = 98. Looking at the second case, if 7x = 42, that means x = 6 so the other number is 3 * 6 = 18.
Answer:
B / px= k
Step-by-step explanation:
B = kpx
Divide each side by px
B / px= kpx/px
B / px= k
C is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
Step-by-step explanation:
for that we use Pythagoras, as the distance is always the baseline (Hypotenuse) of a right-angled triangle created by the x and y coordinate differences between the 2 points.
15.
distance² = (8-3)² + (9-2)² = 5² + 7² = 25 + 49 = 74
distance = sqrt(74) = 8.602325267...
16.
we need to write down the point coordinates first :
(-4, 3)
(1, -3)
distance² = (1 - -4)² + (-3 - 3)² = 5² + (-6)² = 25 + 36 = 61
distance = sqrt(61) = 7.810249676...
