Answer:
2x - 2y = 14
x - y = 2
1.) x = 2+ y
2.) 2(2+ y) - 2y = 14
3.) 4 + 4y - 2y = 14
4.) 4y - 2y = 14 - 4
5.) 2y = 10
6.) 2y/2 = 10/2
7.) y = 5
x - y = 2
8.) x - 5 = 2
9.) x = 2 + 5
10.) x = 7
Therefore, x = 7 and y = 5
Step-by-step explanation:
1. First make one of the variables in any equation the subject of the formula
2. Then substitute the variables equating to the subject of the formula
3. Group the like terms,then solve the equation.
4. Replace the value you will find in the first equation into the other equation.
5. Repeat with the same
First use distributive property on -3(t+5), which would be -3t minus -15.
Then, add all like terms: -3t-15+4t+2 ---> -3t+4t+2-15 --> t-13.
t-13=8, add 13 to both sides. This cancels the -13 and makes 8 to 21.
Therefore, t=21
Answer:
= cos4x
Explanation:
cosAcosB = [cos(A-B)+cos(A+B)]
Given: 2cos(2x)cos(2x)
= 2[cos(2x-2x)+cos(2x+2x)]
= 2cos4x^2
Answer:
Note that both the x and y coordinates are multiplied by the SAME value, k. Given ΔDEF with center of dilation the origin (0,0) and scale factor of 2, plot ΔD'E'F'. As shown in the formula above, multiply each x and y coordinate value by the scale factor of 2 to find the new coordinates
