Answer: (3, 8)

Step-by-step explanation:

x | y
3 | 8
6 | 6
7 | 8
9 | 12

Notice that y=8 when x=3 and when x=7, so this is either a parabola or an absolute value function.

The axis of symmetry passes the midpoint of x=3 and x=7 so the axis of symmetry is x = 5.

(6,6) is given. It's mirror image across the axis of symmetry is (4, 6).

Similarly, (9, 12) is given. It's mirror image is (1, 12).

And (7, 8) is given. It's mirror image is (3, 8). This is the only pair available as given options for this question.

Side note: Notice that the slope between (6, 6), (7, 8), and (9, 12) is the same (equal to 2) so this is the graph of an absolute value function.

What is the probability that a point chosen at random in the given figure will be inside the larger square and outside the small

liraira [26]

Answer:

51/100

Step-by-step explanation:

The probability that a point chosen at random in the given figure will be inside the larger square and outside the smaller square is equal to the ratio of the area of interest to the total area:

P(inside larger square and outside smaller square) = area of interest / total area

P(inside larger square and outside smaller square) = area inside the larger square and outside the smaller square / area of the larger square

Calculations:

1. Area inside the larger square: side² = (10 cm)² = 100 cm²

2. Area inside the smaller square = side² = (7cm)² = 49 cm²

3. Area inside the larger square and outside the smaller square

100 cm² - 49 cm² = 51 cm²

4. P (inside larger square and outside smaller squere)

51 cm² / 100 cm² = 51/100

What is the value of x in the equation x - y = 30, when y = 15? O4 O 8 O 80 O 200

olganol [36]

$\frac{1}{5}x - \frac{2}{3} y = 30 \\$

Putting the value of Y = 15

$\frac{1}{5} x - \frac{2}{3} \times 15 = 30 \\ \frac{1}{5} x = 30 + 10 \\ \frac{1}{5} x = 40 \\ x = 5 \times 40 \\ x = 200$

So, X = 200

Solve for the unknown variable. 144=-12(x+5)

dolphi86 [110]

Answer: x=-17

Step-by-step explanation:

We first distribute the -12 across to the (x+5)

144=-12(x+5)

144=-12x-60

Then, we add 60 to both sides.

204 = -12x

Lastly, we divide the equation by -12.

204/-12 = -12x/-12

-17 = x
