Answer:
4.5
Step-by-step explanation:
Mean = (4+5+6+3)/4 = 4.5 bubbles
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Step-by-step explanation:
First step:
Calculate a slope.
The formula of a slope:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the points (5, -4) and (-1, 8). Substitute:
Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line:
<em>add 10 to both sides</em>
Finally:

Answer: x = -6</h2>
<h3>
Step-by-step explanation:</h3>
To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)
<h3>
</h3>
since -4 = (2/3)x [mutiply both sides by 3]
⇒ -4 × 3 = 2x [divide both sides by 2]
⇒ (-12/2) = x [simplify by dividing -12 by 2]
∴ x = -6
