Answer:

x = > 2

Step-by-step explanation:

This is the answer because:

1) >2 means x is any number greater than 2

2) For example, 2 x 3 = 6 + 7 = 13

3) 13 is greater than 11

Hope this helps!

Solve the system of linear equations below.

Olegator [25]

Answer:

B. x = 2, y = 6

Step-by-step explanation:

$2x + 5y = 34...(1) \\ \\ x + 2y = 14 \\ \therefore \: x = 14 - 2y...(2) \\ \\ from \: equations \: (1) \: and \: (2) \\ \\ 2(14 - 2y) + 5y = 34 \\ \therefore \: 28 - 4y + 5y = 34 \\ \therefore \: 28 + y = 34 \\ \therefore \: y = 34 - 28 \\ \huge \red{ \boxed{\therefore \: y = 6}} \\ substituting \: y = 6 \: in \: equation \: (2) \\ x = 14 - 2 \times 6 \\ \therefore \: x =14 - 12 \\ \huge \purple{ \boxed{\therefore \: x =2}} \\ \\ \huge \orange{ \boxed{ \therefore \: x = 2, \: \: y = 6}} \\$

3. Classify each function according to whether it is a vertical stretch, a vertical compression, a horizontal

Vladimir79 [104]

The classifications of the functions are

A vertical stretch --- p(x) = 4f(x)
A vertical compression --- g(x) = 0.65f(x)
A horizontal stretch --- k(x) = f(0.5x)
A horizontal compression --- h(x) = f(14x)

<h3>How to classify each function accordingly?</h3>

The categories of the functions are given as

A vertical stretch
A vertical compression
A horizontal stretch
A horizontal compression

The general rules of the above definitions are:

A vertical stretch --- g(x) = a f(x) if |a| > 1
A vertical compression --- g(x) = a f(x) if 0 < |a| < 1
A horizontal stretch --- g(x) = f(bx) if 0 < |b| < 1
A horizontal compression --- g(x) = f(bx) if |b| > 1

Using the above rules and highlights, we have the classifications of the functions to be

A vertical stretch --- p(x) = 4f(x)
A vertical compression --- g(x) = 0.65f(x)
A horizontal stretch --- k(x) = f(0.5x)
A horizontal compression --- h(x) = f(14x)

Alisiya [41]

Answer:

The lodge is 21 feet tall.

Step-by-step explanation:

Ski Lodge:

object/shadow

x/3

Ski Pole:

object/shadow

3.5/0.5

Solve for x:

x/3 = 3.5/0.5

0.5x = 10.5

x = 21

Mrs. Lin is sewing costumes for her grandchildren. She is making three lion costumes, one zebra costume, and two bear costumes.

stepladder [879]

Answer:

$12\frac{1}{8}\ yd$

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

$3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})$

Convert mixed number to an improper fraction

$1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}$

$2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}$

$2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}$

substitute

$3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})$

$5+\frac{21}{8}+\frac{9}{2}$

$\frac{40+21+36}{8}=\frac{97}{8}\ yd$

Convert to mixed number

$\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd$
