Second one is a
im pretty sure
7x7=49 and 8x8=64
This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
Answer:
A
Step-by-step explanation:
The formula for flipping smth over the x axis is(x,y)→(x,−y)
just flip the symbol on the second #
your points are:
(-4,-2)→(-4,2)
(0,-4)→(0,4)
(-4,-5)→(-4,5)
Once you graph it, youll see that the shapes are congruent, just flipped, therefore the answer is A
Answer: x = 37 and y = 11
Explanation:
Let x be the bigger number
Let y be the smaller number
x + y = 48
But x is 7 less 4 times the smaller number.
=> x = 4y - 7
Substitute this value of x:
4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11
Substitute the value of y in to the equation:
x + 11 = 48
x = 48 - 11
x = 37
Therefore, x = 37 and y = 11
815.755 is already rounded to the nearest hundredth so i'm guessing you meant hundred. if so the answer is 816
