Answer:

<h2>3. If a ≥ b, then a + c ≥ b + c </h2><h2>4. If c > d, then a– c < a – d</h2>

Step-by-step explanation:

The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.

The other choices aren't correct. For example, the first choice: a – b < a + b, it's not true, because you must apply the same change at each side of the inequality, otherwise you'll ruin the expression.

Choices 2 and 5 are also false.

Therefore, the right answers are 3 and 4.

Find the value of x so that the polygons have the same perimeter.
Novosadov [1.4K]

Answer: x=4

Step-by-step explanation:

The perimeter´s formula for this kind of polygons is

The triangle perimeter would be:

(x+2)+(x+3)+(x+3)

And the rectangle:

(x+2)+(x+2)+x+x

For them to have the same value, we should equal them:

(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x

Working with this:

3x+8=4x+4

x=4

Can you please help me please I really need help
Cerrena [4.2K]

Answer:

1)86

2)102

3)118

4)134

Step-by-step explanation:

1) so we know that the photographer started off with 86 photographs and has been uploading 16 each month since then

so in month 1 she would have 86

in month 2: 86+16=102

month 3: 102+16=118

month 4: 118+16=134

you could also use the expression

y=16x+70

how to get this equation: get slope(16) by subtracting p coords and m coord

substitute slope in slope intercept form

y=16x+b

insert in a coordinate pair(1,86)

86=16+b

b=70

hence y=16x+70
