Plug in (-1, 3) into both equations

Ax - 2y = 4

A(-1) - 2(3) = 4

-A - 6 = 4 Add 6 on both sides

-A = 10 Divide -1 on both sides

A = -10

5x + By = -1

5(-1) + B(3) = -1

-5 + 3B = -1 Add 5 on both sides

3B = 4 Divide 3 on both side

B = $\frac{4}{3}$

if 22000 pots with 15 seeds each are used in a nursery, how many total seeds, in scientific notation?

kipiarov [429]

Write the total number of seeds in scientific notation

Given:

Number of pots = 22,000

Number of seeds = 15

Total number of seeds = Number of pots × Number of seeds

= 22,000 × 15

= 330,000

Scientific notation is written in multiples of 10

Count the number of digits
Insert a decimal point between the first digit and other digits
count the number of digits after the first digits
multiply by 10 raise to the power of number of remaining digits after first digits

= 3.30000 × 10^5

Therefore,

the total number of seeds in

scientific notation is 3.30000 × 10^5

Question included in the image - geometry problem.

iren [92.7K]

Answer:

y = 116°

Step-by-step explanation:

Given that L₁ || L₂:

The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the two opposite and non-adjacent remote interior angles.

Also, ∠y° and ∠2x° are same-side interior angles formed by the intersection of the hypotenuse of the triangle that acts as a transversal to the parallel lines, L₁ and L₂. Given that ∠y° and ∠2x° are same-side interior angles, then it means that they are the supplements of each other, such that the sum of their measures is 180°.

Now that we have established these definitions, we can proceed with the solution.

Equation 1: ∠y° + ∠2x° = 180° ⇒ Same-side interior angles

Equation 2: ∠y° = ∠x° + ∠84° ⇒ exterior angle theorem

Substitute the value of m∠y° from Equation 2 into Equation 1 to solve for the value of x:

∠y° + ∠2x° = 180°

∠x° + ∠84° + 2x° = 180°

Combine like terms:

∠3x° + ∠84° = 180°

Subtract ∠84° from both sides:

∠3x° + ∠84° - ∠84° = 180° -∠84°

∠3x° = 180° - ∠84°

∠3x° = 96°
