The equation for slope intercept form is: y = mx + b
Any equation where m = --2 is correct in your cause.
So, the only equation with a slope of --2 are:
y = --2 + 4
3y = --6x + 12
--3(y - 4) = 6x
Most of these have to be simplified in order to find the correct slope. Hope this helps!
Answer:
8 is the probablitiy
Step-by-step explanation:
4+5=9 -1 = 8
First convert the distance to miles
<span>9.5 × 10^12 km x 0.62 miles/km </span>
<span>= (0.62 × 9.5) x 10^12 miles </span>
<span>= 5.9 × 10^12 miles </span>
<span>But we want to triple that, because it is 3 light years (not just 1): </span>
<span>3 x 5.9 × 10^12 miles </span>
<span>≈ 18 × 10^12 miles </span>
<span>≈ 1.8 × 10^13 miles </span>
<span>Next divide by the speed to get the time (in hours). </span>
<span>t = 1.8 × 10^13 miles / 17000 miles/hour </span>
<span>Let's convert the speed to scientific notation: </span>
<span>t = 1.8 × 10^13 / 1.7 x 10^4 </span>
<span>t = (1.8 / 1.7) × (10^13 / 10^4) <-- when dividing powers with the same base, subtract the exponents </span>
<span>t ≈ 1.1 × 10^9 </span>
<span>Let's convert that back to standard notation. </span>
<span>Answer: </span>
<span>1,100,000,000 hours</span>
1/2
1 cup of vinegar to 2 cups of water
or
0.5/1
Half a cup to 1 cup
Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so
substitute the values
simplify
That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
