Mr. Capp runs his own disc golf store every Saturday. The first customer of the day came in and bought
1 driver and 2 putters for $43. The second customer came in and bought 3 drivers and 1 putter for $69.
How much money does one driver and one putter cost at Mr. C's store?
Answer:
a driver costs $19, while a putter costs $12
Step-by-step explanation:
driver = d
putter = p
1d + 2p = 43
3d + 1p = 69
d + 2p = 43. eq 1
3d + p = 69. eq 2
make d the subject of the equation
d = 43 - 2p. eq 3
substitute the value of d in eq 3 in eq 2
3(43 - 2p) + p = 69
129 - 6p + p = 69
collect like terms
129 - 69 = 6p - p
60 = 5p
p = 12
substitute the value of p in eq 3
d = 43 - 2(12)
d = 43 - 24
d = 19

Answer:
x = 6+3y
y = y (any number)
the rest should follow the same steps
Step-by-step explanation:
2x-6y=12 -> divide both sides by 2 (GCF)
x-3y = 6 -> solve for x, because it has 1 as its coefficient, or the lowest coefficent
x = 6+3y
-5x+15y=-30 -> divide both sides by 5
-1x+3y=-6 -> plug in x from previous equation
-(6+3y) + 3y = -6
-6-3y+3y = -6
y = y

What do you have to multiply the first equation by
to have the x's be opposite and the same?
Answer:
To be able to find what a variable equals, it has to be the only variable in the equation. Having an equation where a variable is opposite of another equation allows you to find the value of the other variable.
Step-by-step explanation:
A

A

27
h
=
4
Work out the value of
x
.
Answer:
Step-by-step explanation:
A= h(x + 10)^2
27 = 4(x + 10)^2
(x + 10)^2 = 27/4
x + 10 = √27/2
x + 10 = 3√3/2
x = 3√3/2 - 10

Working together, Shawn and Hector can install a tile floor in 6 hours. It would take Shawn 9 hours to do the job alone. What is the value of r, Hectora's rate of work in part per hour?
The Hectora's rate of work in part per hour is 18 hours
Given the following parameters:
The time it takes Shawn and Hector to install a tile floor is 6 hoursTime taken by Shawn to install a tile is 9 hoursTime taken by Hectora to install a tile is r hoursTaking the sum of the reciprocals of the time taken;
1/6 = 1/9 + 1/r
1/r = 1/6 - 1/9
1/r = 9-6/54
1/r = 3/54
Cross multiply
3r = 54
r = 54/3
r = 18 hours
Hence the Hectora's rate of work in part per hour is 18 hours

The point (-5,0) is plotted on a coordinate plane.

A-(0,5)
B-(-5,0)
C-(0,-5)
D-(5,0)
[tex]\huge\boxed{Hello! :)}[/tex]
We plot the point (-5,0) on the coordinate plane.
Then, we reflect it over the y-axis.
Remember the rule:
If a point has coordinates (x, y), and the point is reflected over the y-axis, the new point's coordinates are: (-x,y)Let's use this rule now.
We reflect (-5,0) over the y-axis.
(-5,0)
The new point is: (5,0)

Is - 4 the absolute value of 3 – 7? Explain.
Answer:
See below:
Step-by-step explanation:
Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you today!!
We can solve this problem in a single step, we just need to know more about absolute value.
Absolute value is the distance a number is away from 0. For example, if we need to find the absolute value of -7, it would be 7 as the distance can not be negative.
Since we know that, we can solve the problem using algebra and our new logic we got.
[tex]|3-7|=-4?\\4\neq -4[/tex]
We can see that -4 is not the absolute value, 4 is as the distance is 4 and cannot be negative.
Cheers!

Imagine that you have been asked to do an infomercial for a new sous vide tool. You are instructed to not only explain how the tool works but what some of the benefits of this cooking method are. Write a brief script that you could use for this infomercial.
Answer:
Sous vide is the process of sealing some kind of protein in an airtight “vacuum” container and then submerging it in the water at a specific temperature. By sealing them up and dropping them in a large pot of water to cook, there is no fire, no heated metal, no steam, and no smoke. And oddly enough, the water never even comes to a full boil—it just rests at the exact temperature the protein needs to reach for “doneness.” It takes a little longer than some other methods, and it guarantees to never overcook the protein, which can be particularly wonderful if you like your steak with just that perfect amount of pinkness. Sous vide machines used to be specialized equipment for fancy restaurants, but not anymore. These days, a lot of home cooks use small, affordable pots with the exact same cooking power. If you’re having friends over for dinner, sous vide makes pre-party prep a whole lot easier, plus sealed proteins can be kept in the fridge for at least one week. It also guarantees you will never overcook that $30 filet mignon again or stand over a hot stove when you’d rather be doing something else. And because the slowness of sous vide method allows fibers within the protein to contract more slowly, the meat stays juicier.

}
System.out.println( );
What does this code print on the monitor?
a. 1 2 3 4 5 6
b. 0 1 2 3 4 5 6
c. 0 3 6
d. 0 1 2 3 4 5
e. 0 3
Answer:
the answer is c.036
Step-by-step explanation:
it can't be a, b or d because count is being increased by 3 and not 1. And it can't be e because the loop is <= and not < so when the count is 6 it is still in the loop. So it will show the 6 as well

A bag of fruit contains 4 apples and 2 banans 3 oranges and 5 peaches. Darlene will randomly select two piecies of fruit one at a time from the bag and not put them back what is the probabilty that the first piece of fruit Darlene secelts will be on apple and the second piece of fruit will be orange
Answer:
6/91
Step-by-step explanation:
Total number of fruits = 4 + 2 + 3 + 5 = 14
Apple: 4/14
One of the fruits have been taken from the total. 14 thus becomes 13.
There are 3 oranges
Orange: 3/13
Combine probability: 4/14 * 3/13 = 12/182 = 6/91
Two is a common factor in both 12 and 182

which equations match the graph
Answer:
A.) f(x)=1/3x + 1 and g(x)=1/3(6x)+1
Step-by-step explanation:
because firs you see the graph of intercepts or vertex.
see y-intercepts : our graph crosses though 1
the first choice crosses at 1 both f(x) & g(x)
the second choice crosses at 1 both f(x) & g(x)
the third choice crosses at -8 both f(x) & g(x) so this can't be answer.
the forth choice crosses at 1 both f(x) & g(x)
see x-intercept : f(x) crosses -3 and g(x) crosses at approximately -1/2
the first choice crosses at -3 at f(x) & - 1/2g(x)
the second choice crosses at -1/2 at f(x) & - 1/6g(x)
the third choice crosses at 8/3 at f(x) & 8/15g(x)
the forth choice crosses at -3 at f(x) & - 3/4(x)
the graph seems crosses at 1/2 at g(x).
so the answer if the first choice.
what is the domain of f? khan academy
Answer:
x cannot = -2
Step-by-step explanation:
if x = -2 then the denominator is 0 and a fraction with 0 as a denominator is undefined.
Answer:
A
Step-by-step explanation:
f(x) = [tex]\frac{x-3}{x+2}[/tex]
The denominator cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be.
x + 2 = 0 ⇒ x = - 2 ← excluded value in the domain
The domain of f(x) is all real values of x such that x ≠ - 2
