Question 3: The degree is 2 and the terms are 3, Polynomial
Step-by-step explanation:
The solution of the equation after solve the equation, 2x − 3 4x = 21 is 4. Option 3 is correct.
<h3>How to obtain the solution of equation?</h3>
To obtain the solution of an equation, the similar terms should be arranged together and then mathematical operation need to be performed to simplify it.
The equation which is provided to solve is,
![2x - 3 +4x = 21](https://tex.z-dn.net/?f=2x%20-%203%20%2B4x%20%3D%2021)
To solve this equation, arrange the like terms as,
![2x - 3 +4x = 21\\2x +4x - 3 = 21\\6x-3=21](https://tex.z-dn.net/?f=2x%20-%203%20%2B4x%20%3D%2021%5C%5C2x%20%2B4x%20-%203%20%3D%2021%5C%5C6x-3%3D21)
Add number 3 both side of the equation as,
![6x-3+3=21+3\\6x=24](https://tex.z-dn.net/?f=6x-3%2B3%3D21%2B3%5C%5C6x%3D24)
Divide both side of the equation with number 6, we get,
![x=\dfrac{24}{6}\\x=4](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B24%7D%7B6%7D%5C%5Cx%3D4)
Hence, the solution of the equation after solve the equation, 2x − 3 4x = 21 is 4. Option 3 is correct.

Answer:
A. y = 2x -9
B. y = -1/2x +1
Step-by-step explanation:
The given line is in slope-intercept form
y = mx + b
where m is the slope. For your given line, the slope is 2.
A. A parallel line will have the same slope. It is convenient to start with a point-slope form of the equation for the line:
y = m(x -h) +k . . . . . for slope m through point (h, k)
You want the equation of the line through (4, -1) with slope 2, so its equation is ...
y = 2(x -4) -1
Simplifying to slope-intercept form, this becomes ...
y = 2x -8 -1
y = 2x -9
___
B. A perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line. That slope is ...
m = -1/2
As above, the point-slope form of the perpendicular line is ...
y = -1/2(x -4) -1
y = -1/2x +1 . . . . . after simplification
21, it says it right in the name.
Answer:
D
Step-by-step explanation:
Proportional relationships come in the form
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
and
is the constant of proportionality. By comparing the general case
and your specific case
, you can see that in your case
