Answer:

The graph has an open circle at 7.
The arrow points left.

Step-by-step explanation:

Adding 10 and dividing by 4, we have ...

4x < 28

x < 7

The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.

The graph has an open circle at 7.
The arrow points left.

Solve 6^x+2 = 10 for x using the change of base formula

pashok25 [27]

Answer:

$x\approx-0.7149$

Step-by-step explanation:

$\displaystyle 6^{x+2}=10\\\\\log_6(6^{x+2})=\log_6(10)\\\\x+2=\frac{\log(10)}{\log(6)}\\\\x+2\approx1.2851\\\\x\approx-0.7149$

Recall that the change of base formula is $\displaystyle \log_a(b)=\frac{\log(b)}{\log(a)}$

Which polynomial is a perfect square trinomial? (4 points) 9x2 − 12x + 4 36b2 − 24b + 16 16x2 − 24x − 9 4a2 − 10a − 25ynomial is

o-na [289]

Answer:

9x² − 12x + 4

Step-by-step explanation:

A perfect square trinomial:

a² + 2ab +b²= (a + b)²

a² - 2ab +b²= (a - b)²

9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²

36b² − 24b + 16

16x² − 24x − 9

4a² − 10a − 25

Valerie has a circular garden. The radius of the garden is 4 feet. She wants to buy edging to outline her circular garden.Which

ss7ja [257]

You'd need to find the distance AROUND the garden, which is also PERIMETER.

To find the perimeter of a circle, you use the following equation:
$2 \pi r$

$2 \pi (4)$ = $8 \pi$

$8 \pi$ = 25.13 ft

I don't know what your answer options are, but chose the option closest to 25.13 ft
