Answer:
Draw a dashed line to represent the graph of 
and shade the portion below the line for positive values of x and y
Step-by-step explanation:
Let
x------> the number of nickels in the box
y------> the number of dimes in the box
we know that
Multiply by 
both sides
------> inequality that represent the situation
The solution of the inequality is the triangular shaded area below the dashed line
see the attached figure
therefore
The statement which best describes the steps to graph the solution to the inequality in x and y is
Draw a dashed line to represent the graph of and shade the portion below the line for positive values of x and y
Answer:
(x-10)²+(y+9)²= 324.
Step-by-step explanation:
For this question, you will need to substitute these values into the equation of a circle:
(x-h)²+(y-k)²= r²
'h and k' represent the center points, and 'r' represents the radius.
This will result in:
(x-10)²+(y+9)²=324.
Answer:
Step-by-step explanation:
Fist let's have a look :
- (AB) is parallel with (CD) and there is a line crossing them both.
Now the first question : What is the size x ?
- We notice that x and 53° are vertically opposite so they are corresponding angles
- so the size of x is 53°
The second question : what is the size of y ?
- We notice that y and 53° are alternate angles
- so they are corresponding angles with same size
- y=53°
The trick is to khow the situation where we have corresponding angles
F(x) = x²
k = 2
f(x) + k = x² + 2
kf(x) = 2x²
f(x + k) = (x + 2)²
f(x + k) = (x + 2)(x + 2)
f(x + k) = x(x + 2) + 2(x + 2)
f(x + k) = x(x) + x(2) + 2(x) + 2(2)
f(x + k) = x² + 2x + 2x + 4
f(x + k) = x² + 4x + 4
f(kx) = (2x)²
f(kx) = 4x²
The answers are f(x) + k and f(x + k).
Answer:
y = 49 1/3
Step-by-step explanation:
1/8y-2/3=5.5
1/8y = 5.5 + 2/3
multiply both sides by 8:
y = 8(5.5 + 2/3) = 44 + 16/3 = 44 + 5 1/3 = 49 1/3
