On multiplying with -2 in the equation 
given in the question we get as 13y = -26
Answer: Option(d)
<u>Step by Step Explanation:
</u>
Solution;
The given two set of equations such as
(Equation 1)
(Equation 2)
Also given, Marybeth multiplies the first equation by -2
After multiplying with -2 in first equation we get
![-2 \times[3 x-5 y]=-2 \times[10]](https://tex.z-dn.net/?f=-2%20%5Ctimes%5B3%20x-5%20y%5D%3D-2%20%5Ctimes%5B10%5D)
Adding the newly obtained equation 1 and Equation 2,
![[-6 x+10 y=-20]+[6 x+3 y=-6]](https://tex.z-dn.net/?f=%5B-6%20x%2B10%20y%3D-20%5D%2B%5B6%20x%2B3%20y%3D-6%5D)
Adding the like terms x, y and constants we get
13y=-26
Result:
Thus on multiplying and simplifying the above two equations gives answer as 13y = -26
Answer:
24 ounces.
Step-by-step explanation:
Given that the ratio of blue paint to yellow paint in a green paint mixture is 2:3.
Actual ounces used for blue paint = 16
By ratio and proportion property we have
2:3 = 16:x where x is the actual ounces of yellow paint used.
Simplify using ratio rules
if a:b = c:d then ad = bc
We get
2x=3(16) = 48
Divide by 2
x = 24
Hence 24 ounces of yellow paint to be used.
Given:
The graph of a function.
To find:
The domain and range of the function.
Solution:
We have, the graph of a function and we need to find the domain and range of the function.
We know that, domain is the set of input values (x-values) and range is the set of output values (y-values).
From the given graph it is clear that function is defined for all values of x except x=0 because as x tends to 0 the function tends to negative or positive infinite. So, domain can be any real number except 0.
From the given graph it is clear that the value of function can be any real number except y=0. So, range can be any real number except 0.
Therefore, the correct option is B.
