Answer:
<h2>y = 2x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
=======================================
We have the points (-2, 1) and (-4, -3). Substitute:
Put the coordinates of the point (-2, 1) to the equation:
<em>add 4 to both sides</em>
Finally:
For one pair of socks you pay $12 plus $2 shipping.
Let's use x as the variable for how many pairs of socks someone might buy.
If someone buys 5 pairs of socks, they will pay $62. $12 * 5 + $2
So, we can write the expression as 12x + 2.
First, since all of the terms are multiplied, you can cancel them out to simplify them:
18/9 = 2
When a term has exponents on the top and bottom of a fraction, you subtract the bottom from the top:
c^8/c^3 = c^5
d^9/d^6 = d^3
So now, we can get rid of the fraction bar and put all of these terms into one expression:
2(c^5)(d^3)
Answer:
1/2
Step-by-step explanation:
4 of the 8 marbles are blue:
4/8 = 1/2
Answer:
25 and 35
Step-by-step explanation:
Let the numbers be 5x and 7x
(5x+5)/(7x+5)=3/4
4(5x+5)=3(7x+5)
20x+20=21x +15
20-15=21x-20x
5=x
So,the numbers will be
5x=5*5 =25
7x=7*5=35
