Line k passes through the point (6, -7) and has a slope m=-= 2 Which is the equation of a line that is parallel to line k and passes through the point (-4, 9)?
Answer:
k = -2x + 1
Step-by-step explanation:
Assuming slope is -2 (and not -=2)
9 = -4(-2) + b
9 = 8 + b

You need nuts and bolts for an art project. You have $20 to spend and you can buy nuts for 45 cents each and bolts for 80 cents each. You need at least 30 pieces total. Write a system of inequalities to represent this situation. Let x = #nuts and y= # bolts.
mandle is making 15 cups of fruit salad . what ration of grapes to blueberries should she use?
Answer:
12:3
Step-by-step explanation:
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
The function represented by the table is
y = 0.25x
Then, as Mandie is making 15 glasses of fruit salad, we have:
y + x = 15
We have two equations and two unknowns that we must solve.
y = 0.25x
y + x = 15
Resolving
For x:
0.25x + x = 15
1.25x = 15
x = 15 / 1.25 = 12
For y:
y = 0.25x = 0.25 (12) = 3
Answer
The ratio of grapes to blueberries she should use is 12: 3

What is the system of equations?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
(1) Systems of equations
2x + y = 12
x = 9 − 2y
See the graph given below the solution is the point (5,2).
(2) Systems of equations
x + 2y = 9
2x + 4y = 20
See the graph given below the solution is the point has no solution the two lines are parallel.
(3) Systems of equations
x + 3y = 16
2x − y = 11
See the graph given below the solution is the point (7,3).
(4) Systems of equations
y = 11 − 2x
4x − 3y = -13
See the graph given below the solution is the point (2,7).
(5) Systems of equations
y = 10 + x
-3x + 3y = 30
See the graph given below the system has no solutions.
(6) systems of equations
2x + y = 11
x − 2y = -7
See the graph given below the solution is the point (3,5).
Therefore, the solutions to the system of equations are given below in the figure.

Which best describes the graph of the function f(x) = 4(1.5)x?
Answer:
B
Step-by-step explanation:
Since this Equation isn't linear because of the squaring, we can eliminate A and C which imply linear functions. Then it's as easy as pluging in zero for the equation and seeing which one works, and you get an answer of B
Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.
=======================================================
Work Shown:
Distance = rate*time
rate = distance/time
----------------
For Sarah, she runs 324 m in 61.3 seconds. Her speed is:
rate = distance/time
rate = (324 m)/(61.3 sec)
rate = (324/61.3) meters per second
rate = 5.28548 meters per second approximately
----------------
Repeat the same set of steps for Emily
rate = distance/time
rate = (324 m)/(60.4 sec)
rate = (324/60.4) meters per second
rate = 5.36423 meters per second approximately
----------------
The last thing to do is subtract the results we got
5.36423 - 5.28548 = 0.07875
This then rounds to 0.08 meters per second when rounding to two decimal places.

B.y=1/2x
C.y=1/2x
D.y=2x
Answer:
D. y = 2x
Step-by-step explanation:
The slope of the line is 2, so you get 2x. Therefore, the equation is y = 2x.
Answer:
the equation is answer D
Step-by-step explanation:
the slope is 2 and the y-intercept (b) is zero so it isn't written.
What’s the answer to this geometry problem?
Answer:
x = 3
Step-by-step explanation:
(13x - 2) and (12x + 1) are vertically opposite angles and are congruent , so
13x - 2 = 12x + 1 ( subtract 12x from both sides )
x - 2 = 1 ( add 2 to both sides )
x = 3
There are 144 people in an audience. The ratio of adults to children is 5 to 3. How many children are in the audience.
Answer:
In the audience, there are 90 adults and 54 children
Step-by-step explanation:
If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.
We can express this situation into an equation by saying 5x + 3x = 144
8x = 144
x = 18
So now we know there are 5(18) = 90 adults for every 3(18) = 54 children
In the audience, there are 90 adults and 54 children
Answer:

Using the line of random numbers to run one simulation,
what proportion of students tried out for a sport?
O 0.40
A study reported that about 40% of high school students
have tried out for a sport at their school. To find out if this
applies to Jessica's school, she surveyed an SRS of 20
students. Nine of them said that they had tried out for a
sport. To see if this result is surprising, a simulation is to
be conducted to estimate the probability of obtaining a
sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4-9 represent students who did not try out for a sport.
