Answer:

k = \frac{13}{2}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

note the line crosses the y-axis at - 3 ⇒ c = - 3

y = 2x - 3 ← is the equation of the line

Since (k, 10) lies on the line then the coordinates of the point make the equation true.

substitute (k, 10) into the equation and solve for k

10 = 2k - 3 ( add 3 to both sides )

13 = 2k ( divide both sides by 2 ), hence

k = \frac{13}{2}

to make mortar you mix 1 shovel of cement with 5 shovels of sand. how much sand do you need to make 30 shovels of mortar
pantera1 [17]
It takes 5 shovels of sand to make 1 shovel of mortar so how many will it take to have 30 shovels of mortar? You can put this in a proportion. 5/1 = x/30 You don't need to worry about the cement since it's asking for sand. Cross multiply and you get x·1 and 30·5. So this means you need 150 shovels of sand. x=150 when you multiply 30·5.

Simplify 2(x + y) + 3(x + y). <br> 2xy + 3xy <br> 5xy <br> 5x + 5y
Flauer [41]
2(x + y) + 3(x + y)

first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y

your answer is: 5x + 5y

hope this helps
