Answer:

  -4y +49

Step-by-step explanation:

Use the distributive property to eliminate parentheses. Then combine like terms.

  7(y +7) -11y

  = 7y +7·7 -11y

  = y(7 -11) +49

  = -4y +49

HELP!!! Lucas deposits $250,000 into two investment accounts. Over a year, the first account
prohojiy [21]

The amount deposited in the account that earns 3.6% interest is $57,600 and the amount  deposited in the account that earns 2.1% interest is $192,400

The first step is to determine the amount of interest he earned in total over a year

Interest = Amount in the account - amount deposited

$256,114 -  $250,000 = $6,114

The second step is to formulate two set of equations and use simultaneous equation to solve the question

a + b = $250,000 equation 1

0.036a + 0.021b = $6,114 equation 2

Where a represent amount deposited in the account that earns 3.6% interest

b  represent amount deposited in the account that earns 2,1% interest

Multiply equation 1 by 0.036

0.036a + 0.036b = 9000 equation 3

Subtract equation 2 from 3

2886 = 0.015b

divide both sides of the equation by 0.015

b = $192,400

Substitute for b in equation 1

a + 192,400 = 250,000

a = 250,000 - 192400

a = $57,600

Consider the functions f(x) = -2(x-3)² + 2 which is represented by the graph
ehidna [41]

The intervals of the function on the graph are:

  • Domain = (-∝, ∝)
  • Range = (-∝, 2]
  • Increases (-∝, 3]
  • Decreases [3, ∝)

<h3>The key features of the function?</h3>

The function is given as:

f(x) = -2(x-3)² + 2

See attachment for the graph.

From the graph, we have;

Domain = (-∝, ∝)

Because it takes all real values as its input

Range = (-∝, 2]

Because it has a vertex of (3, 2) and the vertex is a maximum

Also, it increases on the interval (-∝, 3] and decreases on the interval [3, ∝)

Please explain how to do this.

All triangles must equal 180°. So there you have a right angle which = 90° and a 25° angle. add those together to get 115°. Now do 180-115=65°. the missing angle is 65°.
