Answer: TRUE

Step-by-step explanation:

A right triangle has to have one angle equal to 90 degrees. All isosceles triangles are equilateral. The only requirement for an isosceles triangle is for at minimum 2 sides to be the same length. An isosceles triangle can have more than 2 sides of the same length, but not less.

Which function is a quadratic function? y – 3x2 = 3(x2 + 5) + 1 y2 – 7x = 2(x2 + 6) + 7 y – 2x2 = 6(x3 + 5) – 4 y – 5x = 4(x + 5

Answer:

Option A.

Step-by-step explanation:

The general form of a quadratic function is

$y=ax^2+bx+c$

It means, power of y should be 1 and highest power of x should be 2.

In option A,

$y-3x^2=3(x^2+5)+1$

$y-3x^2=3x^2+15+1$

$y=3x^2+16+3x^2$

$y=6x^2+16$

It is a quadratic function.

In option B,

$y^2-7x=2(x^2+6)+7$

Here, power of y is 2. So, it is not be a quadratic function.

In option C,

$y-2x^2=6(x^3+5)$

Here, highest power of x is 3. So, it is not be a quadratic function.

In option D,

$y-5x=4(x+5)+9$

Here, highest power of x is 1. So, it is not be a quadratic function.

Therefore, the correct option is A.

Solve for j 6j+16=4j-10

prisoha [69]

$\text {Hello! The answer to your problem is j=-13}$

$\text {Subtract 4j:}\\\text {6j+16-4j=4j-10-4j}\\\text {2j+16=-10}$

$\text {Subtract 16:}\\\text {2j+16-16=-10-16}\\\text {2j=-26}$

$\text {DIVIDE both sides by 2:}\\\text {2j/2=-26/2}\\\text {x=-13}$

$\text {Hope this helps!}\\\\\text {-LimitedX}$
