A recipe for a soup calls for 3/6 cup of chopped onion and 1/4 cup of chopped
celery. What is the total amount of celery and onion needed for the soup help me.
Answer:
3/4
Step-by-step explanation:
Here,cup of chopped onions=3/6
cup of chopped celery=1/4
Then,
total amount celery and onion needed for the soup =3/6 + 1/4
=3*2 + 1*3/12
=6+3/12
=9/12
=3/4
Find the equation of the line that goes through the point (2, -3) and has a slope of -1.
y = -x - 1
y = 2x - 3
y = -x - 3
y = -x + 2
Answer:
y = -x - 1
Step-by-step explanation:
soo since we already know the slope we can subsitute it to the slope form equation
y = mx + b
y = -x + b
now to find the y intercept we have to subsitute the given point
-3 = -(2) + b
-3 = -2 + b
b = -1
Answer:
y = -x - 1
Step-by-step explanation:
Using the process of elimination, we can immediately eliminate b) (y = 2x - 3).
Why? It has a slope of 2, and our answer wants a line with a slope of -1.
y = mx + b
m is the slopeb is the y-intercept.To find the line that goes through (2, -3), we substitute our 3 answer choices (A, C, and D) with 2 (for x-values) and -3 (for y-values).
(2, -3)
y = -x - 1
-3 = -2 - 1
-3 = -3
This statement is true
(2, -3)
y = -x - 3
-3 = -2 - 3
-3 = -5
This statement is false
(2, -3)
y = -x + 2
-3 = -2 + 2
-3 = 0
This statement is false
Therefore, the correct answer is a) y = -x - 1

You can catch a bus near your home to and from work for $3.75 a day. The monthly pass is
$70. Assuming that you work about 22 days a month, how much can you save by buying the
pass?
O $5.00
O $3.75
O $12.50
O $82.50
Answer:
$12.50
Step-by-step explanation:
I multiplied $3.75 by 22 to figure out how much you would make in that month.
3.75 x 22 = $82.50
I then subtracted $70 from $82.50 to figure out how much you would have left after buying the pass.
82.50 - 70 = $12.50

write a function to describe the relationship of the values in the table (-9,-3) (-6,-2) (-3,-1) (0,0) (3,1)
y=1/3x
Step-by-step explanation:A linear function is a relationship that has a degree of 1 and a constant slope. Linear functions are written in the form of y=mx+b, where m is the slope and b is the y-intercept.
Y-intercept
The y-intercept of a function is the y-value when x=0. In this case, we are given all of the coordinates. One of the coordinates is (0,0), which means that when x=0, y=0. So, the y-intercept is 0.
Slope
The slope is the change in y over the change in x. Using the coordinates we can find the slope through the formula [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]. It will be easiest to use the coordinates (0,0) and (3,1). Plug these points into the formula to find the slope.
[tex]\frac{1-0}{3-0}[/tex] = [tex]\frac{1}{3}[/tex]This means that the slope is 1/3.
Answer
Using the information found in the previous sections we can create the final answer, y=1/3x+0, or just y=1/3x.

Anthony drove 140 miles in 2 1/2 hours. He then drove the next 3 1/4 hours at a rate that was 6 miles per hour slower than his first rate. How many miles did Anthony drive in all?
Answer:
302.5 miles
Step-by-step explanation:
using the relationship
D = ST ( D is distance, S is speed and T is time in hours )
given he drove 140 miles in 2 [tex]\frac{1}{2}[/tex] = 2.5 hours , then
S = [tex]\frac{D}{T}[/tex] = [tex]\frac{140}{2.5}[/tex] = 56 mph
the next part of his journe is 6mph slower, that is 50 mph for 3 [tex]\frac{1}{4}[/tex] = 3.25 hours, then
D = ST = 50 × 3.25 = 162.5 miles
total distance travelled = 140 + 162.5 = 302.5 miles

Which two consecutive integers does sqrt20 fall between? Explain your reasoning for. For example, sqrt5 is between 2 and 3, because 5 is between 2^2 and 2^3
Answer:
4 and 5
Step-by-step explanation:
√20 is between 4 and 5 because 20 is between [tex]\sf 2^4[/tex] and [tex]\sf 2^5[/tex]:
[tex]\sf 2^4=16[/tex] and [tex]\sf 2^5=32[/tex]
Answer:
It falls in between 4 and 5
Step-by-step explanation:
Hello!
We can find the perfect squares that are before and after 20.
Perfect squares are numbers that are made by multiplying a number by itself. Numbers that are multiplied by itself 3 times are called perfect triples.
To find the square root of a number is to find out what number multiplied by itself gives us the number.
The perfect square before 20 is 16, as it is 4², or 4 x 4
The perfect square after 20 is 25, as it is 5², or 5 x 5
Therefore, the square root of 20 will fall between 4 and 5.

What is the equation of this line in slope-intercept form?
y = 3x - 1
y = -3x -1
y = -⅓x -1
y = 3x + 1
Answer:
y = -3x - 1
Step-by-step explanation:
To find the slope, use the slope formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Plugging in the given values, we have: [tex]\frac{-4-2}{1-(-1)}[/tex]
[tex]\frac{-4-2}{1-(-1)}[/tex]
= [tex]\frac{-6}{2}[/tex]
= -3
Now that we know that the slope is -3, we need to find the y-intercept. Anazlyzing the graph, we can see that the line passes through the point (0, -1) on the y-axis, therefore, that is our y-intercept.
Combining the information, the result is: y = -3x - 1
