Answer:
x=-2
y= 8
Step-by-step explanation:
Given data
10x – 2y = -36-----------1
7x – 2y = -30--------------2
-Subtract to eliminate y
3x-0= -6
3x= -6
x= -6/3
x= -2
Put x= -2 in
7(-2)– 2y = -30
-14-2y=-30
-14+30=2y
16=2y
y= 16/2
y= 8

Translate the statements to algebraic expression
Represent the power with x;
So, the left hand side is
<em>Power of 10: </em>
<em />
<em>Times n: </em>
<em />
<em />
The right hand side is:
<em>0.1515 * power of 10: </em>
<em />
Equate the right hand side to the left:
Hence;
<em>The required expression is </em><em />
Answer:
-5/4
Step-by-step explanation:
y2 - y1
x2 - x1
________

Slope = -5/4
Hey there! :)
Answer:
Choice B.
Step-by-step explanation:
We can eliminate each graph:
a). This is what is known as a step function. This is incorrect.
b). This is an exponential function because the graph is shaped like a geometric equation. This means that the rate of change is exponential. This is the correct choice.
c). This is an absolute value function. This is incorrect.
d). This is a graph of a polynomial. This does not represent an exponential function, which makes it incorrect.
