It seems like it just wants you to multiply the numbers inside by 3 soooo :
N = (-2 , 0 / 3 , 5) * 3
N = (-6 , 0 / 9 , 15)
Answer is C.
The first 5 is placed in the hundreds place. The second 5 is in the tens place.
we have
using a graph tool
see the attached figure
The solution is the shaded area
<u>Statements</u>
<u>A The slope of the line is .</u>
The statement is False
Because the slope of the line is equal to
<u>B The graph of is a dashed line</u>
The statement is True
The graph of the inequality is a dashed line, because it has no equal signs in the problem
<u>C The area below the line is shaded</u>
The statement is False
Because The solution is the area above the dashed line
<u>D One solution to the inequality is </u>
The statement is True
because
For and
substitute in the inequality
--------> the inequality is satisfied
<u>E The graph intercepts the y-axis at </u>
The statement is True
see the attached figure
Answer:
a) 5xy + 9yz + 3zx + 5x - 4y
Step-by-step explanation:
→ (7xy + 5yz - 3zx) + (4yz + 9zx - 4y) + (-3xz + 5x - 2xy)
→ (7xy - 2xy) + (5yz + 4yz) + (-3zx + 9zx - 3xz) + (5x) + (-4y)
→ 5xy + 9yz + 3zx + 5x - 4y
Hence, option (a) is the correct answer.
Answer:
x + y = 4 Equation 1
y = 2x -1 Equation 2
-2x + y = -1
x + y = 4
Subtract
You will get
- 3x = -5
Divide by -3
-3x / -3 = - 5 /-3
x = 5/3
Substitute x into equation 1
x + y = 4
x = 5/3
5/3 + y = 4
y = 4 - 5/3
y = 7/3
x = 5/3 y = 7/3
Hope this helps.
