Answer:
(1,-1)
Step-by-step explanation:
The solution to a system of equation means the x and y values if we were to solve both equations (of lines) simultaneously.
That is also known as the intersecting points.
The top-right part is known as the 1st Quadrant in a coordinate system.
Top-left is 2nd Quadrant.
Bottom left is 3rd Quadrant.
Bottom right is 4th Quadrant.
The values of x and y (positive or negative) of each quadrant is shown below:
- Quadrant 1: x +ve, y +ve
- Quadrant 2: x -ve, y +ve
- Quadrant 3: x -ve, y -ve
- Quadrant 4: x +ve, y -ve
The intersection point (solution) of the 2 lines shown is in the 4th quadrant, which has x values positive and y values negative.
From the answer choices, we see that 3rd answer choice goes with this -- (1,-1), so this is the correct choice.
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
Answer:
f(x)= 0.5^x has all real numbers as its domain
Step-by-step explanation:
We have three functions:
f(x)= 0.5^x while g(x) and p(x) are line segments
g(x) is a line segment which passes through the two points (-1.8,-3) and ( 1,3.8)
Its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers.
Like wise domain of function p(x) will be [1.7, 1], which is also the subset of real numbers.
But when we look at f(x) it has all the possible value of x. Thus we can say that f(x)= 0.5^x has all real numbers as its domain.
