Angl is a square. The equation of line NG is Y= 1/2 X - 6. Find the equation of line LG in slope intercept form given that the coordinates of L are (-5,1)
Answer: y=-2x-9
Step-by-step explanation:
If ANGL is a square, then NG and LG are adjacent sides.
Adjacent sides are perpendicular. [Each angle is 90°]
The equation of line NG is [tex]Y=\dfrac12 X-6[/tex].
By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)
slope =[tex]\dfrac12[/tex]
Let slope of LG be n, then
[tex]n\times \dfrac{1}{2}=-1[/tex] [Product of slopes of two perpendicular line =-1]
[tex]\Rightarrow n=-2[/tex]
Equation of a line passes through (a,b) and have slope m is given by :-
[tex](y-b)=m(x-a)[/tex]
Equation of LG :
[tex](y-1)=-2(x-(-5))\\\\\Rightarrow\ y-1=-2x-10\\\\\Rightarrow\ y=-2x-9[/tex] [In intercept form]

Suppose you deposited $400 in a savings account 3 years ago. The simple interest rate is 3.3%. The
interest that you earned in those 3 years is $39.60. Which of the following is/are true?
1 = 3
r=3.3%
p = 400
t = 39.60
Help me please
Answer:
Step-by-step explanation:
Given parameters:
Principal = $400
Time = 3years
Interest rate = 3.3%
Interest = $39.60
Now let us verify;
I = interest
r = rate
p = principal
t = time
i = 3 incorrect, interest is $39.60
r=3.3% Correct, rate is 3.3%
p = 400 Correct, principal is 400
t = 39.60 Incorrect, time is 3years

Answer:
1st choice c>190.29
Step-by-step explanation:
First I subtracted 668 from 2000 ad got 1332. I then divided 1332 by 7 since they are collecting cans on the final 7 days. and got 190.285714286. When I round up the answer I got 190.29. Now I can immediately know that the 2nd choice is wrong. In the first sentence of the question, it said "more than 2,000" so based on that I know it's the answer choice with the greater than sign.
Hope this help you :)
Answer:
the third one or C
Step-by-step explanation:
2000-668=1332
1332÷7= 190.285
round
190.29
C > (pretend their is a line under the >) 190.29

What is the answer to this equation? 2x+2x+2=4x+2
Answer:
0
Step-by-step explanation:
You start off with 2x + 2x + 2 = 4x + 2.
You would then add like terms, as shown below.
4x + 2 = 4x + 2
Now, you would subtract 4x from both sides, and that would leave you with:
2 = 2
You would now subtract 2 from both sides, which would now leave you with 0.
Please answer this, I’m a bit confused...
Will ran the diagonal distance across a square field measuring 40 yards on each side. James ran the diagonal distance across a rectangular field with a length of 25 yards and a width of 35 yards. Who ran a longer distance, and how much longer did he run?
Answer: The distance across a rectangular field is longer distance.
So, Perimeter of rectangle would be 120 yards.
Diagonal of square would be 56.56 yards.

What is the value of x in the triangle?
Answer:
Step-by-step explanation:
Q
Answer:
B
Step-by-step explanation:
Since there are 2 congruent angles then the triangle is right isosceles.
The 2 legs of the triangle are therefore congruent ( both x )
Use Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + x² = (3[tex]\sqrt{2}[/tex] )² , then
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = [tex]\sqrt{9}[/tex] = 3 → B
Round 5949.69836527 to the nearest hundredth.
rounding numbers
Answer:
It would be 5949.70
Step-by-step explanation:
The hundreds place is the first two number after a decimal point. In this case it would be 6 and 9. Now if were rounding to the hundredths, you would look at the number right after 9 to see if you could round up. That number happens to be an 8, and if that number is greater than 5, than it will round up the number before it. Now since 8 would round up nine, that would make it a 10, but that can not happen, so you would have to round up the first number as well, which would give you .70.

5949.70

First, we would need to create an equation for this problem. Let x represent the unknown number of hours.
4(6 + x) = 48
Next, you would simplify the equation.
24 + 4x = 48
Now, you would combine like terms.
4x = 24
Your last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 4.
x = 6
I hope this helps!
