Answer:

x = 6, y = -113

Step-by-step explanation:

10x - y = 53 --- Equation 1

y = [tex]\frac{-13x+92}{2}[/tex] --- Equation 2

I will be using the substitution method.

Substitute y = [tex]\frac{-13x+92}{2}[/tex] into Equation 1:

10x - y = 53

10x - ([tex]\frac{-13x+92}{2}[/tex]) = 53

I want to make the denominators on the left side of the equation the same, so I will multiply 10x by 2 so that I can get a fraction.

[tex]\frac{20x}{2}[/tex] - ([tex]\frac{-13x+92}{2}[/tex]) = 53

Now that their denominators are both 2, I can combine the numerators under the same denominator.

[tex]\frac{20x-(-13x+92)}{2}[/tex] = 53

Two minuses, one outside a bracket and one inside makes a plus. One plus and one minus make a minus.

[tex]\frac{20x+13x-92}{2}[/tex] = 53

Evaluate like terms.

[tex]\frac{33x-92}{2}[/tex] = 53

Shift the (÷2) over to the right side and turn into (×2).

33x - 92 = 53 × 2

               = 106

Shift the (-92) over to the right side and turn into (+92).

33x = 106 + 92

      = 198

Find x.

x = 198 ÷ 33

x = 6

Substitute x = 6 into Equation 1:

10x - y = 53

10(-6) - y = 53

Evaluate.

-60 - y = 53

Shift the (-60) over to the right side and turn into (+60).

-y = 53 + 60

   = 113

Find y.

y = -113

Answer:

3.528

Step-by-step explanation:

First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.

Answer:

A

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Consider the triangle (in which angle4 is present)

by angle sum property,

20 + 40 + angle4 = 180

60 + angle4 = 180

angle4 = 180 - 60

angle4 = 120

Also,

angle2 = 120 (vertically opposite angles)

angle1 + angle2 = 180 (linear pair)

angle1 + 120 = 180

angle1 = 180 - 120

angle1 = 60

Answer:

7 feet long

Step-by-step explanation:

This set up will give a right angle triangle where;

Length of the ladder is the hypotenuse = x

The distance of the ladder to the house is the adjacent = 3 feet

Angle of elevation theta = 72 degrees

Using the CAH in trigonometry identity;

cos theta = adjacent/hypotenuse

cos 72 = 3/hyp

hyp = 3/cos72

hyp = 3/0.4258

hyp = 7.05 feet

Hence the ladder is approximately 7 feet long

Answer:

k = 4/3

Step-by-step explanation:

Formula for k: y/x

If y = 4 and x = 3, then we use the formula (y/x) in order to find the constant of proportionality:

k = 4/3

Answer: the train traveled 43km southwards

Step-by-step explanation:

First, let's define.

North as the positive y-axis.

East as the positive x-axis.

And the initial position of the train is (0, 0).

Now, we know that:

"A train first travels east for 20 kilometers."

The new position will be:

(0, 0) + (20km, 0) = (20km , 0)

"Then it turns north and travels for 43 kilometers."

The new position will be:

(20km, 0) + (0, 43km) = (20km, 43km)

"Next it goes west for 20 kilometers."

If East if the positive x-axis, then West is the negative x-axis.

The new position of the train will be:

(20km, 43km) + (-20km, 0) = (0, 43km)

Then it travels south for an unknown number of kilometers, such that the final position is the same as the initial position, then if the train goes X kilometers to the south (and because North is the positive y-axis, South will be the negative y-axis), we have:

(0, 43km) + (0, -X) = (0, 0)

(0, 43km - X) = (0, 0)

Then we must have that:

43km - X = 0

43km = X

This means that the train traveled 43km southwards.

Answer:

x = -1

Step-by-step explanation:

3(x + 2) = -5 -2(x-3)

open parenthesis

3 * x + 3 * 2 = -5 +  -2 * x + -2 * -3

3x + 6 = - 5 - 2x + 6

subtract 6 from both sides

3x + 6 - 6 = -5 - 2x + 6

3x = -5 -2x

add 2x from both sides

3x + 2x = -5 - 2x + 2x

5x = -5

divide both sides of the equation by 5

5x/5 = -5/5

x = -5/5

x = -1

Answer:

f(x)=43

Step-by-step explanation:

you put the 5 in the places where the x is so

F(5)=9(5)-2

45-2=43

Step-by-step explanation:

-3^2 / 9^6

-3^2 / 3^2

(9 divided by 3 = 3 and 6 divided by 3 = 2)

It would now be -1 because a negative divided by a positive gives a negative.
