Answer:
reflectional
Step-by-step explanation:
(5-3)/(9-3) is 2/6
The slope is 1/3
Answer:
Number of dimes = 3
Number of nickels = 7
Number of quarters = 5
Step-by-step explanation:
Let x be the number of dimes in the jar.
The amount of nickels is one more than twice the number of dimes, then the amount of nickels is 
The number of quarters is one half the total number of nickels and dimes, so the number of quarters is 
Fill in the table
Thus, the total sum in cents is
The total amount of money in the jar is $1.90 that is 190 cents. So,
![57.5x+17.5=190\\ \\575x+175=1,900\ [\text{Multiplied by 10}]\\ \\575x=1,900-175\\ \\575x=1,725\\ \\x=3](https://tex.z-dn.net/?f=57.5x%2B17.5%3D190%5C%5C%20%5C%5C575x%2B175%3D1%2C900%5C%20%5B%5Ctext%7BMultiplied%20by%2010%7D%5D%5C%5C%20%5C%5C575x%3D1%2C900-175%5C%5C%20%5C%5C575x%3D1%2C725%5C%5C%20%5C%5Cx%3D3)
Number of dimes = 3
Number of nickels = 7
Number of quarters = 5
Check the total amount of money in the jar:
If the terminal ray of an angle passes through (-5, -3), that means it passes through x coordinate -5 and y coordinate -3. Both x and y are negative in only one quadrant and that is the third one. If we plot the point (-5, -3) in the coordinate plane in Q3, and then draw a vertical line to connect that point to the negative x axis and then draw a line to connect that point to the origin, what we have created is right triangle with a base of -5 and a height of -3. The tangent ratio relates the side opposite the reference angle to the side adjacent to the reference angle. We have both of those measures already and do not have a need for the length of the hypotenuse since the tangent ratio doesn't use it. The tangent of the reference angle is -3/-5 which is 3/5.
Answer:
B) (3, one-half)
Step-by-step explanation:
(3)+2×(1÷2) = 4
2×(3)-2×(1÷2) = 5
