Answer:

B. (4, 28)

Step-by-step explanation:

y=8x-4

x=4

Let x = 4 in the first equation:

y = 8(4) - 4

y = 32 - 4

y = 28

x = 4; y = 28

Answer:

  y -4 = -2(x -(-11))

Step-by-step explanation:

The point slope formula is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

__

So, the boxes in order from left to right are k, m, h.

The problem statement tells you the point is (-11, 4), so h = -11, k = 4. It also tells you the slope is -2, so m = -2.

Putting these numbers in the required order, we have k = 4, m = -2, h = -11 and the equation of the line is ...

  y-\boxed{4}=\boxed{-2}(x-\boxed{-11})

HELP ME PLEASE [WILL GIVE BRAINLIEST TO BEST ANSWER WITH BEST EXPLAINATION]
Marysya12 [62]

Hi there!

\large\boxed{\text{33 in}^2}

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.

Rectangles:

A = l × w

A = 2.75 × 4 = 11 in²

Solve for the other rectangle's length by subtracting from the total:

12 - 2 - 3 - 4 = 3

A = 3 × 3 = 9 in²

Total rectangle area: 11 + 9 = 20 in²

Trapezoid:

A = 1/2(b1 + b2)h

A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²

Triangle:

A = 1/2(bh)

A = 1/2(2.5 · 2) = 2.5 in²

Add up all of the areas:

20 + 10.5 + 2.5 = 33 in²

I only need help on number 6 plzzzz help
Gennadij [26K]
That question is asking for the time so your answer will specifically be in hours. And I'm not sure if you divide or you multiply but I'm pretty sure the correct answer is dividing because tomorrow so cancel the miles they will be left with hours. I don't know if that makes sense to you but it kind of makes sense to me somehow.

The diameter of the Sun is about 1.4 x 106 km. The diameter of the planet
den301095 [7]

Answer:

1.17*10²

Step-by-step explanation:

Diameter of the sun is about 1.4 × 10⁶ km

1.4*10⁶ km = 1,400,000

Diameter of the planet venus is about 12000 km

12000 km = 1.2 × 10⁴

Ratio of the diameters

Sun : Venus

1.4 × 10⁶ km : 1.2 × 10⁴

1.4 × 10⁶ km / 1.2 × 10⁴

1.4 / 1.2 × 10^6-4

1.166 × 10²

Approximately

1.17 × 10²
