Answer:
the third one 10 cm, 9cm 9cm
Answer:
-3 4/9
Step-by-step explanation:
The fractions all have the same denominator, so are easily added.
Of course, you know how to add signed integers.
4/9 - 3/9 - 5/9 + 5 - 8
= (4 -3 -5)/9 +(5 -8)
= -4/9 -3
= -(3 4/9)
Hi there! The answer is y = -3x - 21
Let's set up the equation of the line step by step! First we need to know that we need to set up an equation in slope-intercept form. We get the following:
y = ax + b.
a represents the slope of the line.
b represents the intercept with the y-axis.
Since our new line is parallel to y = -3x + 1, both lines have the same slope. Therefore the slope of our line, which is represented by a, is -3.
y = -3x + b.
We also know that this line goes through the point (-5, -6) and therefore we can plug in these coordinates into our formula.
-6 = -3 × -5 + b
Simplify
-6 = 15 + b
Subtract 15
-21 = b
Switch sides
b = -21
Hence, y = -3x - 21
~ Hope this helps you!
