Answer:

Quadrant 1

Step-by-step explanation:

how I understood this is first understanding how a graph works. Once you understand that you can count 13 horizontal on the "X" Axis, then go 18 up on the "Y" axis. you should get a point in the upper left area and that area is called Quadrant 1. Say if 13 was negative instead of going horizontal east you would go horizontal west. And the point should end up in Quadrant 2. Any more questions feel free to ask me below.

timofeeve [1]

Answer:

Step-by-step explanation:

A = 70*M

B = 500 + 50*M

Costing the same means equal, so we have the equation:

70M = 500 + 50M

-50M -50M

20M = 500

20M / 20 = 500 / 20

Write the equation of the line that passes through the given lines (0,-2) and (4,1)

Gala2k [10]

Answer:

y = 3/4x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step 1: Define

(0, -2) y-intercept

(4, 1) random point

Step 2: Find slope m

$m=\frac{1-(-2)}{4-0}$

$m=\frac{1+2}{4}$

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

y = 3/4x + b

Step 3: Write linear equation

y = 3/4x - 2

n 1/3 more on Tuesday
so we are going to fine Tuesday's amount , to find what fraction did Gail sell on the two days

2/7 + 1/3
find lCM which is 21
u add and get 13/21 so 31/21+2/7=19/21

Can you please help me with this two questions

Natali [406]

Answer:

2) d. 60°

3) a. AB

Step-by-step explanation:

Question 2

ΔABC and ΔCDA are congruent because:

they are both right triangles

they share one side (AC)

their hypotenuse are parallel (marked by the arrows)

This means the corresponding side lengths and angles are equal.

Therefore,

∠CDA = ∠ABC

⇒ x = 60°

Question 3

The hypotenuse is the longest side of a right triangle - the side opposite the right angle (the right angle is shown as a small square).

Therefore, the hypotenuse of ΔABC is the line AB.
