The rules tell me to add the exponents. But I when I started algebra, I had trouble keeping the rules straight, so I just thought about what exponents mean. The " a6 " means "six copies of a multiplied together", and the " a5 " means "five copies of a multiplied together". So if I multiply those two expressions together, I will get eleven copies of a multiplied together. That is:
Answer:
45lbs
Step-by-step explanation:
Because 190lbs (2020 weight) - 145lbs (2006 weight) = 45lbs
So
1/2x+2=2/3x
convert to common fraction
1/2=3/6
2/3=4/6
3/6x+2=4/6x
subtract 3/6x from both sides
2=1/6x
multiply boh tisdes by 6
12=x
the tank can hold 12 gallon
Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
Answer: *An image created by a reflection will always be congruent to its pre-image.
*Corresponding angles and segments are always congruent in a reflection of a figure.
*An image and its pre-image are always the same distance from the line of reflection.
Step-by-step explanation:
Since, reflection is a rigid transformation therefore, it preserves the shape of the figure and create congruent images.
And we know that if if two figures are congruent then their corresponding angles and sides are congruent.
Reflection maps a figure to create its mirror image, and the distance of object and image is always equal from the mirror, therefore "An image and its pre-image are always the same distance from the line of reflection."
