Answer:$104.5
Step-by-step explanation:
cats=c
Dogs=d
2c+3d=455
d=82
Substitute d=82 in 2c+3d=455
2c+3(82)=455
2c+246=455
Collect like terms
2c=455-246
2c=209
Divide both sides by 2
2c/2=209/2
c=104.5
1 cat cost $104.5
Answer:
4y^(2)+14y+31
Step-by-step explanation:
First you need to do (y+7)(y+7)
y^2+7y+7y+49
y^2+14y+49
Add it all together
y^2+14y+49+3y^2-15
4y^(2)+14y+31
Answer:
C
Step-by-step explanation:
A reference angle is formed by the terminal side and the horizontal axis (aka x axis). Replace each "access" with "axis" as those are typos. By definition, a reference angle is between 0 and 90 degrees so the angle is always acute.
Answer: Choice B
Reflection is the way of projecting a mirror figure to the other side of the axis of symmetry. When reflection is done, like what we can observe in the mirrors, the properties that can be observed are parallelism, colinearity and angle measure. Orientation is not preserved. Answer is C
