Answer:

<1 = 55 degrees and <2 = 35 degrees

Step-by-step explanation:

Sum of complementary angles is 90.

<1 = 3x + 10

<2 = 4x - 25

3x + 10 + 4x - 25 = 90

7x - 15 = 90

7x = 105

x = 15

<1 = 3(15) + 10

<1 = 55

<2 = 4(15) - 25

<2 = 35

Answer:

y + 1 = 7(x + 2)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

Slope m = 7

Point (-2, -1)

Step 2: Write Equation

Substitute in variables into general form.

y + 1 = 7(x + 2)

Which ordered pair minimizes the objective function C = 60x + 85y?. (0, 160). (55, 70). (80, 50). (170, 0)

dangina [55]

Step-by-step explanation:

The given objective function is $C = 60x + 85y$

To check that which ordered pair is minimizing the objective function-we will substitute all the ordered pair one by one in the given function and we will calculate the value of C. The ordered pair which will give the minimum value will be the answer.

For (0, 160)

$C=60\times 0+85\times 160=13600$
