Let,
12x + 15y =34--------(1)
-6x + 5y =3-------(2)
(2) x 2 = -12x + 10y =6-------(3)
(3) + (1)
20y =40
y= 2
substitute y=2 into (1)
12x + 15(2) =34
12x =4
x= 1/3
Answer:
33.5
Step-by-step explanation:
4x+5+41=180
4x+46=180
4x=180-46
4x=134
4x=33.5
Answer:
I'm not completely sure but I beileve Jackie less than 4
Step-by-step explanation:
good luck tho
Hey there!
If you look at the image you've been given, you can see that there are four complete repeats of each individual angle. What I mean by this is that you can take that angle, lay it on top of three other angles you've been shown, and it will be the exact same. These are corresponding angles.
An example would be (1, 9, 3, and 11). Any of these are the exact same angle, placement and degree included, as the others. The other examples in this problem would be (2, 10, 4, and 12), (6, 14, 8, and 16), and (5, 13, 7, and 15).
Your answer will be C, angle 3 and angle 11.
Hope this helped you out! :-)
An <em>exponential function</em> is one that has the variable in the exponent of an algebraic expression.
![f(x)=a^{(x+c)}](https://tex.z-dn.net/?f=f%28x%29%3Da%5E%7B%28x%2Bc%29%7D)
is an exponential function. The base (a) does not need to be a constant, but usually is for the functions we study. The exponent here is a linear function of x, but can be any* function of x, including another exponential function.
The number of forms of exponential functions that we can solve is somewhat limited, so our study is usually restricted to those forms. For example, in general, we cannot use algebraic methods to solve equations that involve sums of polynomial and exponential functions, such as ...
![e^{x}+x-3=0](https://tex.z-dn.net/?f=e%5E%7Bx%7D%2Bx-3%3D0)

* if the exponent is a log function, simplification may result in something that is not actually an exponential function. For example, e^(ln(x)) = x, a linear function.
