The answer is 2,268 because 378 times 6 is 2,268
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:
1/7
Step-by-step explanation:
The reciprocal is 1 over the number
The reciprocal of 7 is 1/7
Answer: 2
Step-by-step explanation:
Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
90 ÷ 45 = 2
and therefore:
9 ÷ 4.5 = 2
