Answer:

$x \leq 4$

Step-by-step explanation:

Step 1: Convert into an expression

1/2 x + 8 is less than or equal to 10

$\frac{1}{2}x + 8 \leq 10$

Step 2: Subtract 8 from both sides

$\frac{1}{2}x + 8 - 8 \leq 10- 8$

$\frac{1}{2}x \leq 2$

Step 3: Multiply both sides by 2

$\frac{1}{2}x* 2 \leq 2 * 2$

$x \leq 4$

Answer: $x \leq 4$

Find S7 for the geometric series 2 + -6 + 18 + -54 +…

nikitadnepr [17]

Answer:

1094

Step-by-step explanation:

The sum of terms of a geometric series is given by ...

Sn = a1·(r^n -1)/(r -1)

You want the sum for ...

a1 = 2, r = -3, n = 7

Filling in the numbers, we get ...

S7 = 2·((-3)^7 -1)/(-3-1) = 2(-2188)/(-4)

S7 = 1094

The triangle shown below has an area of 10 units2. Find x. 7 4 x units

SVEN [57.7K]

Answer:

<h3>x = 5 units</h3>

Step-by-step explanation:

area of a triangle = 1/2 base * height

where area = 10 units²

height = x units

base = 4

plugin values into the formula:

10 = 1/2 * 4 * x

x = 10 (2)

x = 5 units

What is the answer to this question?

krok68 [10]

Answer:

$\boxed{\pink{\sf Option \ (1) \ is \ correct . }}$

Step-by-step explanation:

Given function to us is ,

$\implies y = 5x^2 + 10$

And, we need to find the inverse of the equation.

So , for that firstly replace x with y . The equation becomes

$\implies x = 5y^2 + 10$

Now , next we need to solve for y .

$\implies x = 5y^2 + 10 \\\\\implies 5y^2 = x - 10 \\\\ \implies y^2 = \dfrac{x-10}{5} \\\\\implies y = \sqrt{\dfrac{x-10}{5}}$

Now , replace y for $f^{-1}(x)$

$\underline{\boxed{\orange{\tt \implies f^{-1}(x) = \pm\sqrt{\dfrac{x-10}{5}}}}}$

As per the options provided in Question we can that option (1) mathces with our answer when we just interchanged the variables.

Hence option (1) is correct.
