First Simplify the numbers we know. Therefore we get: x2=75/3 which is the same as x2=25

Now find the square root of 25, which is 5 or -5. Therefore x=5 or -5

\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

3x²=75. What is x?

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

First, divide by 3 on both sides:-

x²=25       Next, take the square root of both sides:-

x=5, x=-5 (remember, x² =x times x (x times itself); 5 times itself gives 25, and -5 times itself also results in 25)

\dashrightarrow\bigstar\boxed{\boxed{\underline{\bold{So\:the\:value\:of\:x\:is\:5\:and\:-5}}}}\dashleftarrow

<h3>Good luck.</h3>

If f = {(2,5), (3, 2) (4, 6), (5, 1), (2, 2)), then f is a function.
KiRa [710]

Answer:

false

Step-by-step explanation:

f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.

Find all the zeros of the function y=-7x+8
alexdok [17]

The zero of the function is for x = 0. Put the value of x to the equation

y = -7x + 8:

-7x + 8 = 0        <em>subtract 8 from both sides</em>

-7x =-8       <em>divide both sides by (-7)</em>

\boxed{x=\dfrac{8}{7}}
