6 0

Answer: $\begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{17}{3}\:\\ \:\mathrm{Decimal:}&\:x\le \:5.66666\dots \\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{17}{3}]\end{bmatrix}$

Step-by-step explanation:

$2x-5\le \:-x+12$

$2x\le \:-x+17\\$

$2x+x\le \:-x+17+x$

$3x\le \:17$

$\frac{3x}{3}\le \frac{17}{3}$

$x\le \frac{17}{3}$

Need help its sector area

Paladinen [302]

Area of sector

$= \frac{30}{360} \times \pi \times {(radius)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times {(12)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times 12 \times 12$

so the area = 37.71 square metre

Find the inverse of f (x) = x + 2 + 9

Brut [27]

Answer:

y = x - 11

Step-by-step explanation:

First, turn the f(x) into a y:

y = x + 2 + 9

Now, switch the x and y.

x = y + 2 + 9

Add like terms.

2 + 9 = 11

x = y + 11

Now, solve for y. Subtract 11 on both sides.

y = x - 11

s quadrilateral JKLM the result of a dilation of quadrilateral ABCD by a scale factor of 2? Why or why not?

Likurg_2 [28]

If quadrilateral JKLM has given values, as well as quadrilateral ABCD, it can be concluded from the given values if JKLM is a result of a dilation of ABCD by a scale factor of 2. Dilation factor is used to scale up a given figure. If ABCD has measurements of 1, 2, 3, and 4. Then the measurements of JKLM should be 4, 8, 12, and 16.

The sum of 14 and a number is equal to 17

-Dominant- [34]

The sum of 14 and a number is 14+x

we know that this equals 17, so: 14+x=17.

Let's substract 14 from both sides:

x=17-14

x=3

so the number is 3.
