7x- 5y - 6z= 200
x+y= -10

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

[tex]1) \: \: 12x + 6y + 7z = - 35 \\ 6y = - 35 - 12x + 7z \\ y = \frac{ - 35 - 12x + 7z}{6} \\ \\ 2) \: \: 7x - 5y - 6z = 200 \\ - 5y = 200 - 7x + 6z \\ y = \frac{200 - 7x + 6z}{ - 5} \\ \\ 3) \: \: x + y = - 10 \\ y = - 10 - x \\ [/tex]

A triangle has a base of 16 inches and a height of 1/8 inches. What is its area?

Answers

Answer:

1 in²

Step-by-step explanation:

The area of the triangle calculated using the area formula is 1 in²

Given the Parameters :

Base of triangle = 16 inches

Height of triangle = 1/8 inches

Area of a triangle can be obtained using the relation :

Area = 1/2 × base × height

Substituting the Parameters into the equation :

Area of triangle = 1/2 × 16 × 1/8 = 1 in²

Therefore, the area of the triangle is 1 in²

What is the quotient?

Enter your answer as a simplified fraction in the box.

Answers

5 : 1/6 = 301 = 30. Is the answer

The quotient from the expression (−1/5) ÷ (−4/5), in the simplified fraction is 1/4.

We have,

To calculate the quotient of the expression (−1/5) ÷ (−4/5), you can follow these steps:

- Invert the second fraction (divisor): (-4/5) becomes (-5/4).

- Multiply the first fraction (dividend) by the inverted second fraction: (-1/5) * (-5/4).

- Simplify the result if possible.

(-1/5) * (-5/4)

= (1 * 5) / (5 * 4)

= 5 / 20

Both the numerator and denominator have a common factor of 5, which can be cancelled out:

5 / 20 = 1 / 4

Thus,

The quotient in the simplified fraction is 1/4.

Here is a diagram of triangle DEF.
Find the measures of angles q, r, and s.
(PLEASE help ASAP I will give brainliest!)

Answers

Answer:

q= 100

r= 135

s= 125

Step-by-step explanation:

These are the angles

The measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

What are Alternate Interior Angles?

Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.

These are the angles

⇒ q = 180 - 80  = 100

⇒ r = 180 - 45= 135

⇒ s = 180 - (180 - 80 - 45) = 125

So the sum of the measures of angles q, r, and s

⇒ q + r + s = 100 + 135 + 125 = 360°

Thus, the measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

Use function notation to write the equation of the line. PLEASE ANSWER ASAP

Answers

Answer:

option 2: f(x) = 4x + 4

Step-by-step explanation:

Graph is positive, so with this you should already know that options: 1, 3, 4 are incorrect since those are negative.

However, let's break it down more.

To write the function for a line, you use y = mx+b

m stands for the rise/run

b stands for the y-intercept

Rise over run is 4/1, or just 4

With this we know that option 3 is not correct, yet again

Our y intercept is 4

With this we know that option 1 is not correct, yet again

This just leaves option 2 and 4 with the correct slope and y-intercept, yet as we said before this is a positive slop, so again, 4 is incorrect

Yesterday you borrowed $60 from your brother. Every day that you don't pay it back, you owe $2.00 more. So today, day one, you owe him $62.00, on day two you will owe him $64.00, on day three you will owe him $66.00, etc. If you still haven't paid him back, how much will you owe him on day 25?

Answers

Answer:

110 dollars.

Step-by-step explanation:

Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.

You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.

You owe him 110 dollars.
