Y+9=-3(x-2) standard form
madam [21]

Hello!

"Standard form" looks like Ax + By = C.

Start by carrying out the indicated multiplication:

y + 9=-3(x-2) becomes y + 9 = -3x + 6

We want to group the x and y terms on the left and the constants on the right.  Achieve this by adding 3x to both sides, obtaining:  3x + y + 9 = 6.  Next, subtract 9 from both sides:  3x + y = -3.

The given equation, in standard form, is 3x + y = -3.

There are 400 mangoes in a barrel. Each mango weighs 1. 8 pounds. What is the total weight of the mangoes in the barrel?
Alika [10]

Answer:

720 pounds

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Number of mangoes in a barrel = 400

Each mango weight = 1.8 pounds

So, we can calculate the total weight of mangoes by using following formula,

Total weight = Number of mangoes in a barrel × Each mango weight

By putting value, we get

Total weight = 400 × 1.8 pounds

= 720 pounds

Use the diagram to find the measure of each angle. Enter the number only.
Pavlova-9 [17]

9514 1404 393

Answer:

  a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,

  i = 56, j = 124, k = 56

Step-by-step explanation:

Vertical angles are congruent; linear pairs are supplementary; two angles dividing a right angle are complementary. These are the angle relations you need to know to solve this.

__

Working from the top and from the given angles, ...

  h = 60°

  f = g = 180° -h = 120°

  j = 124°

  k = i = 180° -124° = 56°

  a = 64°

  b = d = 90°

  c = e = 90° -64° = 26°

In summary, measures in degrees are ...

  a = 64, b = 90, c = 26, d = 90, e = 26, f = 120, g = 120, h = 60,

  i = 56, j = 124, k = 56
