Answer:
After finding the solution of given equations by elimination method
-3x-3y=12
-9x+3y=-24
we get the value of x=1 and y= -5
Step-by-step explanation:
is eq A
is eq B
To find out value of x and y we will use elimination method
To find value of x add eq A and eq B
Now to find value of y put x=1 in eq A
so the value of
x= 1
and
y= -5
For checking the solution
putting value of x and y in eq A
Hence proved
Putiing value of x and y in eq B
Hence proved

Step-by-step explanation:
Take the prices and divide by the number of ounces
3.12 dollars/ 24 ounces
.13 dollars/ ounce
Please check, i'm not entirely sure but i'm decent enough.
1 is A 2 is D3 is B
Good luck.
Answer:
f(x) is quadratic. g(x) and h(x) are linear.
Step-by-step explanation:
So we have the three functions:
Linear functions are polynomials in which the highest degree is 1.
Quadratic functions are polynomials in which the highest degree is 2.
And exponential functions usually have a variable in the exponent (e.g. 2^x).
For f(x), the highest degree is 2. Thus, f(x) is a quadratic function.
For g(x), the highest degree is 1 and there are no variables in the exponent. Thus, g(x) is a linear function.
Similarly, for h(x), the highest degree is 1 and there are no variables in the exponents, so h(x) is also a linear function.
You can make a proportion
<em>Cross multiply</em>
8 × 6 = 48
<em>Now, divide 48 by 9</em>
48 ÷ 9 = 48/9
x = 48/9
