Answer:
Same shape and Same angles.
Answer:
4000 sq inches
Step-by-step explanation:
A rectangle is given with sides 82 and 46 inches
We have to round off these dimensions to the nearest 10.
82 inches ~80 inches since 2 <5, we make it 0
Similarly 46 inches ~50 inches since 6>5
Now area
= length x width
=80(50)
=4000 square inches
Option 2 4000 sq inches is correct answer.
A rectangle with sides 15 and w has perimeter
We want this quantity to be at most 50, so it must be less than or equal to 50:
For the record, this implies that
So, the width can be at most 10.
Answer:
B) y + 7 = 5x
Step-by-step explanation:
In math, a linear function is one that has a graph that is a line. It looks like this: There are two things that make up the equation: y = f(x) = a + bx. One independent variable and one dependent variable make up a linear function, which is also called a simple function. The independent variable is x, and the dependent variable is y, which is what you're interested in. Also, there are no exponents in a linear function, which means the exponent is one.
Hey there!
In order to solve this equation for y, you need to use addition, subtraction, and division to combine and simplify the terms. You do this by first eliminating the terms, which you do by completing whatever will make each term equal to zero. Then, you'll repeat this same thing on the other side of the equation, like so:
<span>5y + 3 = 2y – 3x + 5
– 3 – 3
</span>
5y = 2y – 3x + 2
As you can see, I subtracted three from +3 the left side to cancel it out, then repeated that on the right side to the similar term (the constant). Now, just repeat that with your other terms until your equation is equal to y.
5y = 2y – 3x + 2
+ 2y + 2y
<u>7y</u> = <u>–3x + 2</u>
7 7
y = <u>–3x + 2</u>
7
When you can't simplify any more, you have your answer. y will be equal to –3x + 2 over 7.
Hope this helped you out! :-)
