Answer:
18
Step-by-step explanation:
basic math :/
These are 3 questions and 3 answers.
1) Question 18
Answer: 3
Explanation:
i) Equation given: 3x - y = - 4
ii) Transform to slope-intercept form: y = mx + b, where m is the slope.
y = 3x + 4
iii) Then, the slope is m = 3.
2) Question 19
Answer:
17 horizontal layers
43 bricks are left
Explanation:
i) Data:
number of bricks: 5500
number of bricks per horizontal layer: 321
ii) Calculations:
Divide the number of bricks by the number of bricks per horizontal layer: you need both the quotient and the remainder.
5500 ÷ 321 = 17 and 43 are left.
3) Question 20
Answer: indefinite
Explanation:
The line is vertical.
All the vertical lines have indefinite slopes.
That is because the slope is given by:
slope = change in y / change in x.
But x is constant, which means that the change in x is zero. And, since the division by zero is not defined, the slope is not indefinite.
About 450 books and articles Euler completed after he lost his sight entirely.
<h3>Who was Leonhard Euler?</h3>
Leonhard Euler was a mathematician from Switzerland. He introduced the fundamentals of graph theory and topology.
His main field of work includes number theory, mechanics, fluid mechanics, and many more.
The life span of Euler was between 1707 and 1783. In the last few years of his life, he lost the eye sight. But the eye sight loss doesn't affect him from doing his work. In his lifespan, he published around 886 books and articles on various fields or science, mathematics and engineering.
After the total blindness, he published more than 450 books and articles.

Answer: -9^5 = -59049
Step-by-step explanation: you would just multiply -9 by 5.
20 because 3,000.00-2400.00=2100divide by 100 you get 21 u round to 20 so it’s 20 percent
