The range of f(x) = 7 4x is all positive real numbers. true or false

1 answer:

6 0

Please explain what the gap between the 7 and the 4 is, because I'm sure it's not 74x?

Either way, it looks like a linear graph, in which case yes, the range is going to be y∈<span>ℝ. Therefore, it's false, as it's for ALL real values of y, including negative values.</span>

In order for there to be a right triangle formed, this must satisfy pythagoran's theorm thingy:

a^2+b^2=c^2

7^2+15^2=274

22^2= 484

since 274 isnt equal to 484

There is not a right triangle formed here

Find the positive solution of x when:<br><br> 25 = 4/x²

sladkih [1.3K]

1) Multiply both sides by x²

$25 {x}^{2} \: = \: 4$

2) Divide both sides by 25

${x}^{2} \: = \: \frac{4}{25}$

3) Square root both sides

$x \: = \: \frac{2}{5}$

Viola!
