<u>Steps to evaluate your statement: </u>

1. If w = 5.7 and z = -2.9, you just plug the numbers into the equation, -4 w - 3z

2. Your equation should look like this: -4 ( 5.7 ) - 3 ( -2.9 )

3. Multiply -4 into the parentheses, also multiply -3 into the parentheses.

4. Your equation should look like this: -22.8 + 8.7

5. Add -22.8 and 8.7

Your final answer should be: -14.1

For the following linear equations, determine which inverse operation allows you to determine the solution of the equation. In y

VARVARA [1.3K]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

$\frac{n}{5}$ = - 0.3

Since n is divided by 5 then use the inverse operation, multiplication.

Multiply both sides by 5 to clear the fraction

n = 5 × - 0.3 = - 1.5

(2)

Given

- 2n = 4 $\frac{1}{3}$ ← change to an improper fraction

- 2n = $\frac{13}{3}$

Since n is multiplied by - 2 then use the inverse operation, division.

Divide both sides by - 2

n = $\frac{13}{-6}$ = - $\frac{13}{6}$

which of the following are NOT trigonometric identities, Check all that apply a.) sec^(2) x - tan^(2) x=1 b) sec^(2) x+csc^(2) x

Anit [1.1K]

By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are

sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1

So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .

So the correct options are

b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1

Pythagorean Theorem with Known Legs

solniwko [45]

Answer:

$\sqrt{97$

Step-by-step explanation:

The Pythagorean Theorem states that if you square the two legs and take the square root of the two legs, then you get the hypotenuse.

9^2+4^2

=81+16

=97

= $\sqrt{97}$
