Which of the following has a y-intercept of 3 y=3x+2 or x=3or y=2x+3 or y=x
1 answer:
Answer:
We conclude that the equation y=2x+3 has a y-intercept of 3.
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the slope
- b is the y-intercept
Given the equation
y = 3x+2
comparing with the slope-intercept form y = mx+b
The slope-intercept of y = 3x+2 is: 2
Given the equation
x=3
Does not have a y-intercept.
Given the equation
y=x
comparing with the slope-intercept form y = mx+b
The slope-intercept of y=x is: 0
Given the equation
y=2x+3
comparing with the slope-intercept form y = mx+b
The slope-intercept of y=2x+3 is: 3
Thus, we conclude that the equation y=2x+3 has a y-intercept of 3.

Answer:
m=5
Step-by-step explanation:
1. Convert the logarithm into exponential form using the fact that (x)=b is equal to x=
so ... 4m-10=
2. Any expression raised to the power of 1 equals itself so ... 4m-10=10
3. Move the constant to the right-hand side and change its sign so ... 4m=10+10
4. Add the numbers so ... 4m=20
5. Divide both sides of the equation by 4 so ... m=5, m>
6. Check if the solution is in the defined range so ... m=5
