Answer:
Option D is correct
The point slope intercept equation of line =
Step-by-step explanation:
Given: The slope of line (m) = 2 and also it is given from the figure the
Point-slope intercept form: If we have a point and a slope, m, then the formula
we use to find the equation of a line:
.......[1]
Substitute the value of m =2 and (1, 9) in [1];
Therefore, the point slope intercept equation of the line is:
Ok so first off understand what they are saying. there is a movie on sale for $22.10 which is 15 percent of the original price. So now what you do is set up the problem.
22.10 is = 15% of the price
x = 100% of the price (original price)
<u> 15 </u> = <u>22.10
</u>100 x
<u>
</u>now just use cross multiplication.
15x = 22.10 · 100
solve for x.
<u>15x</u> = <u>2210</u>
<u /> 15 15
x = 147.33333333 since the 3's go on forever you can simply put it into a fraction
x = 147 <u>3
</u> 9
<u>
</u>whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9
Answer:
- simplifies to 6x+6=-10
- x = -8/3 = -2 2/3
Step-by-step explanation:
3(4x+2)-6x=5x-5(2+x)
12x +6 -6x = 5x -10 -5x . . . . . eliminate parentheses using the distributive property
6x +6 = -10 . . . . . . . . . . . . . . . collect terms
x +1 = -10/6 . . . . . . . . . . . . . . . divide by 6
x = -1 - 5/3 . . . . . . . . . . . . . . . add -1
x = -8/3 . . . . . . . . . . . . . . . . . simplify
Answer:
6 hours
Step-by-step explanation:
A: y=125+7x
B: y=110+10x
for A to be a better deal than B, 125+7x<110+10x has to be true
- subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3x
- divide by 3: 5<x
- so x has to be greater than 5, im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you
