Tallulah has a dimes and y nickels. She has at most 18 coins worth at
1 answer:
One possible solution for the system of inequalities is given as follows:
13 dimes and 2 nickels.
<h3>How to obtain the system of inequalities?</h3>The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:
- Variable x: number of dimes that Tallulah has.
- Variable y: number of nickels that Tallulah has.
Tallulah has at most 18 coins, hence:
x + y ≤ 18.
A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:
0.1x + 0.05y ≥ 1.20.
The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:
x = 13, y = 2.
Which means that she has 13 dimes and 2 nickels.

Answer:
x=40
Step-by-step explanation:
Both angles are equal. So the equation needs to equal 156.
Just plug in points for x until the answer is 156.
In this case, when we plug in 40, it works!
Answer:
Step-by-step explanation:
Given that L is a line parametrized by
The plane perpendicular to the line will have normal as this line and hence direction ratios of normal would be coefficient of t in x,y,z
i.e. (2,3,-1)
So equation of the plane would be of the form
Use the fact that the plane passes through (2,0,-1) and hence this point will satisfy this equation.
So equation is
b) Substitute general point of L in the plane to find the intersecting point
i.e. same point given.
Answer:
y = x - 3
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 )
Here m = and c = - 3 , then
y = x - 3 ← equation of line
