What is the y-intercept of a line that has a slope of —3 and passes through point (0, -7)?
_7
-3
0
4
Answer:
-7
Step-by-step explanation:
well, y-intercept is value of y when x = 0.
from the problem, we already have the answer, it is -7
but more detailed way is
m = -3
[tex] \frac{y - ( - 7)}{x - 0} = - 3 \\ y - ( - 7) = - 3x \\ y = - 3x - 7 \\ [/tex]
y-intercept is value of y when x = 0
[tex]y = - 3(0) - 7 \\ y = - 7[/tex]

Becca made 960 cookies to sell. She wants to package the cookies in the the boxes of 16 . Her goal is to make $630 from selling her cookies . If each box of cookies is priced the same , how much should Becca charge for each box ?

amy ate 27.5 cookies in 5.5 minutes. How many cookies did she eat per minute?
Answer:
5 cookies per minute.

Answer:
Amy ate 5 cookies per minute
Step-by-step explanation:
Do get the unit rate - the number of cookies per minute - you can divide 27.5/5.5. You then get 5. This means that Amy ate 5 cookies per minute.

7 m/s —> 273 minutes
11 m/s —> M
Criss cross to get M
11x273= 7M
3003=7M
M=429 minutes

The cost of a ticket to a Circus & Fan Fair show is $69 for adults and $26 for children. On a
certain day, 5 times as many children attend the show than adults, and the total revenue is
$94,908. About how many adults bought tickets?
Let the number of adults equal x, and the number of children equal 5x.
26(5x) + 69x = 94908
194x = 94908
x = approx. 489
About 489 adults bought tickets.
A total of 489 adults take tickets to the circus & Fan Fair show.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of tickets that adults bought is a and the number of tickets that children bought is c.
Then,
26(5a) + 69c = 94908
194a = 94908
a = 489.21 but we need to take the whole number and practical number so it will be 489.
Hence "A total of 489 adults take tickets to the circus & Fan Fair show".
