Answer:

x=4

Step-by-step explanation:

3+x=7

Subtract 3 from both sides as Subtraction is the opposite of Addition.

So 7-3 = 4

X=4

What is the exponents

zmey [24]

The exponent of a number says how many times to use the number in a multiplication.

For Example, In 8² , the 2 is the number of times 8 has to be multiplied. In this case It has to multiplied by itself 2 times, 8x8 = 64 so 8² = 64.
Another example is 9³ since the number above is 3 we have to multiply 9 three times, 9x9x9 = 729 which means 9³ = 729.

Hope this helps

Answer the following True or False:

Ilia_Sergeevich [38]

False; consider as a counterexample the function f : ℝ→ℝ defined by

$f(x)=\begin{cases}-3&\text{for }x\neq2\\0&\text{for }x=2\end{cases}$

Clearly f approaches -3 as x gets closer to -2, but neither limit from either side is equal to the function's value at x = 2 (that is, -3 ≠ 0), so f is not continuous.

Write y=-5/8x+3 in standard form using integers?

Ivenika [448]

Answer:

standard form of given equation is 5x - 8y = -3

Step-by-step explanation:

$y= \frac{5}{8}x + 3$

Standard form of linear equation is Ax + By = C

First we remove the denominator 8

We multiply the whole equation by 8

So equation becomes

8y = 5x + 3

Now we move 5x to the left hand side, we subtract 5x on both sides

-5x + 8y = 3

Now we remove the negative side from -5x by dividing the whole equation by -1

5x - 8y = -3
