Plug it into point-slope form.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
So plug in -1 for x1, 2 for y1, and 0.9 for 'm':
y - 2 = 0.9(x + 1)
Simplify to get in slope-intercept form:
Distribute 0.9 into the parenthesis:
y - 2 = 0.9x + 0.9
Add 2 to both sides:
y = 0.9x + 2.9
The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
<u>Solution:</u>
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
Answer:
14/15 meters
Step-by-step explanation:
We add each color of fabric to find the total amount of fabric used.
1/3 +3/5
We need to get a common denominator of 15
1/3 *5/5 = 5/15
3/5*3/3 = 9/15
5/15 + 9/15 = 14/15
Answer:
(2x + 1) (x + 2)
Step-by-step explanation:
2x² + 4x + 1x + 2
They are already arranged, so you just have to find the GCF. 2x² + 4x have the GCF of 2 and 1x + 2 have the GCF of 1.
2x (x + 2) + 1(x + 2)
Now you divide the whole thing by x + 2.
2x (x + 2) + 1(x + 2)/ x + 2
One of them cancels out leaving (2x + 1) and (x+2)
