Y-intercept occurs at x = 0 because x = 0 is where the y-axis is.
Set x = 0 to find the y-intercept value.
the "constant multiplier" is the number that the exponent is on. it is called this because that is the repeated multiplication factor ( example: 2² = 2 · 2 and 2³ = 2·2·2 so it's a constant multiplication)
a. for y = 3 · 6^x, y-intercept is
y = 3 · 6^0
anything to power of 0 is just 1 so we're left with
y = 3 ⇒ y-intercept is 3
Constant multiplier is 6 (exponent on 6)
b. for y = 3/4 · 8^x, the y-int is
y = 3/4 · 8^0 = 3/4 ⇒ y-intercept is 3/4
Constant multiplier is 8
c. for y = 3600 · (1/2)^x, the y-intercept is
y = 3600 · (1/2)^0 = 3600 ⇒ y-intercept is 3600
Constant multiplier is 1/2
Answer: y=
s=-30+10t
Step-by-step explanation:
9x + 2y = 5; y
9x-9x+2y = 5-9x
2y=5-9x
y=
1/15s - 2/3t = -2; s
(1/15s - 2/3t = -2)*15 ==> Get rid of fraction by multiplying both sides by 15
s - 30/3 t=-30
s-10t=-30
s=-30+10t
Answer:
13cm
Step-by-step explanation:
There was a decrease of 20% in membership from October to November.
Step-by-step explanation:
Step 1; To find the percent by which the running clubs membership decreased we must find the difference between the number of members in October and the number of members in November. The number of members in the club in October was 25 whereas it reduced to 20 in the month of November.
Difference in members = Number of members in October -Number of members in November = 25 - 20 = 5
Step 2; To find the percent decrease in number of members in the running club, we divide the difference in number of members by the number of members in November . We multiply this value by 100 to get it in terms of percentage.
Percent decrease in number of members =(Difference in members / number of members in November) *100
= (5/25) * 100 = 0.20 * 100 = 20%
So number of members in the club decreased by 20% from October to November.
