Jason = J, Kim = K
K+325m = J
K = 4.2 km
convert km to m by multiplying by 1000
4.2km * 1000 = 4200m = K
so just plug in your values to get your answer : Jason ran 4525 meters
4200m + 325 = 4525m
-1/2 / 3/4 =
The first step is to flip the second fraction and change division to multiplication. Then multiply straight across.
-1/2 x 4/3 = -4/6
In simplified form:
-4/6 = -2/3
Answer:
The temperature at 9:00 is 14° C.
Step-by-step explanation:
At noon, the temperature was 6° C.
By 5:00, the temperature had dropped to -2° C.
Every hour until 9:00, the temperature rose 4°, so 4•4 is 16.
16 + -2 is 14.
So, the temperature at 9:00 is 14° C.
Answer: No. You reversed the domain and range
#2) B) x ≥ 0
#3) B) [0, ∞)
<u>Step-by-step explanation:</u>
#2 is asking about the domain, which is all of the x-values.
The graph appears to be touching the y-axis so it equals 0 and all other x-values are greater than zero. (0, 1), (1, 0), (2, -0.8), (3, -1.5), etc. All of the x-values are moving toward the right, which is positive infinity. --> x ≥ 0
#3 is asking for the range, which is all of the y-values.
The vertex is at (0, 0) and all other y-values are above zero (positive numbers), moving toward positive infinity. --> [0, ∞)
You can solve it algebraically by simply adding the numbers in the parenthesis and multiplying to get 35x but if you want to solve it using distributive property exclusively then distribute as so
5x(3) + 5x(4)
15x + 20x
35x
