Answer:

Q6. x = 17
Q8. Yes, parallel
Q9. No, not parallel

Step-by-step explanation:

Q6. Solve for x

<u>Use ratios of similar sides</u>

28/(82 - 28) = (2x + 8)/(5x - 4)
28/54 = (2x + 8)/(5x - 4)
14/27 = (2x + 8)/(5x - 4)
14(5x - 4) = 27(2x + 8)
70x - 56 = 54x + 216
70x - 54x = 56 + 216
16x = 272
x = 272/16
x = 17

If ratios are same, the lines are parallel

41.8/33 = (102 - 45)/45
41.8/33 = 57/45
41.8*45 = 33*57
1881 = 1881

Yes, lines are parallel

38/19 = 52/24
2 = 2 1/3

Incorrect, lines are not parallel

Instructions: Use the ratio of a 30-60-90 triangle to solve for the variables.

Pepsi [2]

Answer:

$x=20$

$y=10\,\sqrt{3}$

Step-by-step explanation:

In the triangle we have the following trigonometric equations:

$tan(60^o)=\frac{opposite}{adjacent} \\\sqrt{3} =\frac{y}{10} \\y=10\,\sqrt{3}$

and also:

$cos(60^o)=\frac{adjacent}{hypotenuse}\\\frac{1}{2} =\frac{10}{x}\\x=20$

In a sale, the cost of a coat is reduced from 85 to 67.5

IgorC [24]

Answer:

I’m assuming you’re talking about what percentage was taken off, so in that case the answer would be approximately 20.6%

Step-by-step explanation:
67.5/85 X/100

cross multiply then divide by 100 to find for x and you get 79.4117

then, subtract this number from 100 and you will get 20.6%

Complete the equation of the graphed linear function in point-slope form.

vazorg [7]

The point-slope form:
$y-y_1=m(x-x_1)$
m - slope
x₁, y₁ - the coordinates of a point

It passes through the points (1,-2) and (2,2).
$(1,-2) \\
x_1=1 \\ y_1=-2 \\ \\
(2,2) \\
x_2=2 \\ y_2=2 \\ \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-1}=\frac{2+2}{1}=4$

$\boxed{y-(-2)=4(x-1)}$
