Answer:

44%

Step-by-step explanation:

you add up all the numbers to get the total then divied the single number (eg. 8) by the total. It will then show up as a decimal so in order to get rid of the decimal you multiply by 100. ( eg. 8 ÷50=0.16 → 0.16×100= 16 → 16% )

Equation of a line:
y=mx+c

m = gradient: The difference between two y points and two x points.
m= \frac{\Delta y}{\Delta x}

c = y-intercept: Where the line crosses the y-axis (x=0)

You have:
y=\textunderscore\textunderscore \ x + \textunderscore
so you are missing the m and the c.

To calculate m find two y coordinates -you have (12, <u>7</u>) and (0, <u>1</u>)- and subtract them. Then divide this by the subtracted values of the x coordinates -you have (<u>12</u>, 7) and (<u>0</u>, 1)- This gives:

m= \frac{7-1}{12-0}
m= \frac{6}{12}
m=0.5

To calculate the c, you just see where the line crosses the y-axis. Because you have the point (0, 1), you know that when x=0, y=1. Because x=0 is on the y-axis, you can tell that the line passes through y=1. This makes your c = 1:

c=1

When you plug these values into the equation you get your answer:

y=0.5x+1

Are the expressions -0.5(3x + 5) and -1.5x + 2.5 equivalent? Explain why or why not
Gelneren [198K]

Answer:

Step-by-step explanation:

-0.5(3x + 5)   and   -1.5x + 2.5

-0.5(3x + 5)...distribute the -0.5 thru the parenthesis

-1.5x - 2.5

no, these are not equivalent.... one is -1.5x + 2.5 and the other is -1.5x - 2.5....not the same
