Answer:

The answer to your question is: third option, it's a parabola

Step-by-step explanation:

f(x) = (x + 4)²

f(x) = x² + 4

f(x) = (x - 4)² I think this is the right answer, because when get the vertex, the signs are changed, if the -4 is negative, it means that the graph must be located in +4.

f(x) = x² - 4

Use the order of operations to simplify<br> 5*3 to the second power-15/5

ASHA 777 [7]

Assuming the question reads:

$5 \cdot 3^2 - 15 \div 5$

The order of operations is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

There are no parentheses in the equation.

There is an exponent in the equation. Solve this term first:

$3^2 = 9$

The equation should now read:

$5 \cdot 9 - 15 \div 5$

There are two multiplication/division operations in the equation. Solve them individually:

$5 \cdot 9 = 45$

$15 \div 5 = 3$

The equation should now read:

$45 - 3$

There is one subtraction operation. Solve this term for your answer:

$45 - 3 = \boxed{42}$

89 (54x − 36) + 2 = −3/4 (−40 + 16x) + 90xsolve for x

Amiraneli [1.4K]

Hey! Just in case you have to show your work.

89(54x-36)+2=-3/4(-40+16x)+90x

4806x-3204+2=-3/4×4(-10+4x)+90x

4806x-3202=30-12x+90x

4806x-78x=30+3202

4728x=3232
