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.

Graph a line with a slope of -5 that contains the point -3,-4
guapka [62]

Answer:

The equation of the line is 5x + y + 19 = 0

Step-by-step explanation:

The equation of the line with slope 'm' and given a point (x₁, y₁) passing through it we use the Slope - one - point form which is given by:

                                    y - y₁ = m(x - x₁)

The point given is: (-3, -4) and the slope is -5.

We get the equation of the line to be:

y - (-4) = -5(x - (-3))

⇒ y + 4 = -5(x + 3)

⇒ y + 4 = -5x - 15

⇒ 5x + y + 19 = 0. is the required equation of the line.

How long will the spring be if a 2 pound weight is hung on it? Will the length double if you double the weight?
mars1129 [50]
Logically if you double weight on something it means that you are adding the exact same weight as the first object to the same thing to make it twice the weight as the original, so yes... the weight will double if the length is doubled

The quotient of 8. 4 times 10 Superscript 9 and a number n results in 5. 6 times 10 Superscript 27. What is the value of n? 1. 5
Inessa05 [86]

By simplifying given statement we got that if the quotient of 8.4\times10^ 9 and a number n results in 5. 6\times 10 ^{27} then n is equal to 1.5\times10^{-18}

<h3>What is quotient?</h3>

Result obtained after division is called quotient

Here given that "The quotient of 8. 4 times 10 Superscript 9 and a number n results in 5. 6 times 10 Superscript 27"

We can write it as

The quotient of 8.4\times10^ 9 and a number n results in 5. 6\times 10 ^{27}

we can write it as

\frac{8.4\times10^ 9}{n} =5. 6\times 10 ^{27}

Now we can simplify it as

n= \frac{8.4\times10^ 9}{5. 6\times 10 ^{27}} \\\\n= \frac{8.4}{5.6} \times\frac{10^9}{10^27} \\\\n= 1.5\times 10^{-18}

By simplifying given statement we got that if the quotient of 8.4\times10^ 9 and a number n results in 5. 6\times 10 ^{27} then n is equal to 1.5\times10^{-18}
