Answer:
-11°F
Step-by-step explanation:
The temperature was -4° in the morning. The temperature dropped 7° later.
Subtract 7 from -4.
The temperature should be -11°F.
Hope this helps.
The smallest y-intercept would be of the first function. (0, 6)
Since Blake is starting with $6, that is the y-intercept.
For the function, f(x) = 4^x + 3, the y-intercept is 7.
For the last function, f(x) = 10(2)^x , the y-intercept is 10.
6 is the lowest of 6, 7, and 10.
Answer:
She has 9 5 cent stamps and 6 7 cent stamps.
Step-by-step explanation:
Let the number of five cent stamps be represented by F and the number of seven cent stamps be represented by S.
The difference between the number of five cent and seven cent stamps is 3
F-S=3
The sum of the collection from each type of stamp is 87 cents
5F+7S=87
Let us solve the equations simultaneously.
F-S=3
5F+7S=87
Using substitution method,
F= 3+S
5(3+S)+7S=87
15+5S+7S=87
12S=87-15
12S=72
S=6
F=3+S
=3+6=9
Therefore the number of five cent stamps is 9 and seven cent stamps is 6.
