The system of equations can be solved using linear combination to eliminate one of the variables. 2x − y = −4→10x − 5y = −20 3x
tester [92]

Answer:

Option D is correct.

13x = 39

Step-by-step explanation:

The system of equation is given:

2x-y = -4             ....[1]

3x+5y = 59         .....[2]

Multiply equation [1] by 5 to both sides we have;

10x-5y = -20              .....[3]

Using elimination method:

Add [2] and [3] equations to eliminate y and solve for x, we have;

13x = 39

Divide both sides by 13 we get;

x = 3

Substitute x in [1] we have;

2(3)-y = -4

6-y = -4

Subtract 6 from both sides we have;

-y = -10

Divide both sides by -1 we have;

y = 10

⇒Solution: (3, 10)

Therefore, an equation can replace 3x+5y = 59 in the original system and still produce the same solution is,

13x = 39

Please help solve!!!!!!!!!!
Deffense [45]

Answer:

Height = 17.31821 feet

Step-by-step explanation:

<u><em>Explanation</em></u>

<u><em>From graph</em></u>

Given angle θ = 6.5°  and a = 152 feet

we need to find the height (h)

By using the tangent rule

                   tan \alpha = \frac{opposite side}{adjacent side}

                  tan 6.5 = \frac{b}{152}

    Cross multiplication , we get

               b = 152 × tan 6.5°

               b = 152 × 0.113935

              b = 17.31821 feet

Height = 17.31821 feet
