Write the ratio in simplest form.

Step-by-step explanation:

5x+2y=13

2x+6y=26

[tex]5x = 13 - 2y \\ x = \frac{13 - 2y}{5} [/tex]

[tex]2( \frac{13 - 2y}{5} ) + 6y = 26[/tex]

[tex] \frac{26}{5} - \frac{4y}{5} + 6y = 26[/tex]

[tex]6y - \frac{4y}{5} = 26 - \frac{26}{5} \\ [/tex]

[tex]5.2y = 20.8 \\ y = 4 \\ x = \frac{13 - 2 \times 4}{5} = \frac{13 - 8}{5} \\ x = 1[/tex]

Answer:

[tex]t-223=409[/tex]

Step-by-step explanation:

Since Kiran scored 223 fewer points in a computer game than Tyler, Tyler's score can be represented as:

[tex]k+223=t[/tex], where [tex]t[/tex] is Tyler's score and [tex]k[/tex] is Kiran's score.

Since Kiran scored 409 points, we can set [tex]k=409[/tex]:

[tex]409+223=t[/tex].

Re-arranging this, we get:

[tex]\fbox{$t-223=409$}[/tex].

Step-by-step explanation:

Answer:

A. [tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]

Step-by-step explanation:

Given, slope formula = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

To find an equivalent equation, let's make [tex] y_1 [/tex] the subject of the formula.

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Cross multiply

[tex] 1(y_2 - y_1) = m(x_2 -x_1) [/tex]

[tex] y_2 - y_1 = m(x_2 - x_1) [/tex]

Subtract [tex] y_2 [/tex] from both sides

[tex] y_2 - y_1 - y_2 = m(x_2 -x_1) - y_2 [/tex]

[tex] - y_1 = m(x_2 - x_1) - y_2 [/tex]

Divide both sides by -1

[tex] \frac{- y_1}{-1} = \frac{m(x_2 -x_1) - y_2}{-1} [/tex]

[tex] y_1 = -m(x_2 - x_1) + y_2 [/tex]

Answer:

y = 3x - 8

Step-by-step explanation:

passes through (5, 7) and (4, 4)

Find slope:

(7 - 4) / (5 - 4)

= 3/1

= 3

This is your slope.

Now plug in a set of coordinates.

y = 3x + b

7 = 3(5) + b

7 = 15 + b

b = -8

Your equation is: y = 3x - 8

Check your work by plugging in the second coordinate pair.

y = 3x - 8

4 = 3(4) - 8

4 = 12 - 8

4 = 4

Your solution is correct.

Answer:

  $111.24

Step-by-step explanation:

The use of a 20% off coupon causes the price to be multiplied by (1 -20%) = 0.80. The addition of 7% tax causes the discounted price to be multiplied by (1 +7%) = 1.07. Multiplying the price by these two factors gives ...

  $129.95 × 0.80 × 1.07 = $111.24

The final cost with tax is $111.24.

Sure! Please give brainly if I'm correct, and thank you!

Step-by-step explanation: it is option 2

Answer:

Step-by-step explanation:

12). By applying Pythagoras theorem in the given right triangle,

      Hypotenuse² = (Leg 1)² + (Leg 2)²

      x² = 7² + 7²

      x² = 2(7)²

      x = [tex]\sqrt{2(7)^{2} }[/tex]

      x = [tex]7\sqrt{2}[/tex]

13). By sine rule,

      sin(60)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

      [tex]\frac{\sqrt{3}}{2}=\frac{9\sqrt{3} }{y}[/tex]

      y = [tex]\frac{18\sqrt{3} }{\sqrt{3} }[/tex]

      y = 18

      By cosine rule,

      cos(60)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

      [tex]\frac{1}{2}=\frac{x}{y}[/tex]

      x = [tex]\frac{y}{2}[/tex]

      x = [tex]\frac{18}{2}=9[/tex]

14). By applying Pythagoras theorem in the given right triangle,

      12² = x² + x²

      144 = 2x²

      72 = x²

      x = √72

      x = 6√2

Answer:

HL (hypotenuse leg)

Step-by-step explanation:

They share a leg, meaning they must be an equal length, and the hypotenuse is congruent, so the hypotenuse leg theorem says they are congruent.

Answer:

It is a 67% decrease

Step-by-step explanation:

First subtract the new amount from the old one

[tex]15-5=10[/tex]

Then divide the difference by the original amount.

[tex]10/15-0.67[/tex]

Move the decimal point over two spots (multiply by 100) to get your percentage.

0.67=67%
