Answer:
Both coordinates are negative
Answer:
The x-coordinate is negative, and the y-coordinate is negative.
Step-by-step explanation:
It's a bite hard to explain it without a xy-plane. I don't want to upload it, so I will try to draw it:
[tex]\left[\begin{array}{ccc}a&|&b\\-&-&>\\c&|&d\end{array}\right][/tex]
We have point [tex]a[/tex] in the coordinates [tex](-x, y)[/tex]
We have point [tex]b[/tex] in the coordinates [tex](x, y)[/tex]
We have point [tex]c[/tex] in the coordinates [tex](-x, -y)[/tex]
We have point [tex]d[/tex] in the coordinates [tex](x, -y)[/tex]
A point with a positive x-coordinate and a negative y-coordinate is reflected over the y-axis.
This point is [tex]d[/tex]. Once it is reflected over the y-axis, it turns to be point [tex]c[/tex].

This is because the angle that is 100 degrees is corresponding to the angle next to x, and there’s 180 degrees on a straight line, therefore we do 180 subtracted by 100, and we get 80, which is our answer.
Hope this helps!
As the angle besides the 100 degrees is it’s linear pair that will be 80 degrees that is 180 - 100 and then x = 80 degrees through corresponding angles .

3. A breakfast cereal is made of oats, nuts, and raisins. Each box contains 12 cups of cereal, and 4 cups are oats. What percentage of each box is oats?
Answers
Answer:
Step-by-step explanation:
1) The advertisements boast that 25% of the cereal in each box is almonds. It means that the percentage of the other cereals in the box is 100 - 25= 75%
Therefore, the portion of each box that is not almonds is 75/100 = 0.75
2) The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, then the number of cups of almonds in each box is
25/100 × 12 = 3 cups
3) if each box contains 12 cups of cereal, and 4 cups are oats, then the percentage of each box that is oats is
4/12 × 100 = 33.33%

Write the linear equation in the slope-intercept form when m=1 and b=-12
Answers
Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = 1 and b = - 12 , thus
y = x - 12 ← equation of line

Zac invests $3500 at 8% p.a. simple interest for a period of time, to produce $210 interest. For how long did he invest the money?
Please help me in the steps to finding the answer and also the solution. Thx
Answers
Answer:
9 months
Step-by-step explanation:
simple interest ( I) is calculated as
I = [tex]\frac{PRT}{100}[/tex]
P is the principal, R the rate of interest and T the time in years
Here I = 210, P = 3500 and R = 8, thus
210 = [tex]\frac{3500(8)T}{100}[/tex] = 35 × 8T = 280T ( divide both sides by 280 )
0.75 = T
Thus T = 0.75 years = 9 months
The money was invested for 9 months
Answer:
9 months
Step-by-step explanation:
investment= 3500
interest rate= 8% PA simple
time= x years
Interest= $210
---------------
3500*0.08*x=210280x=210x=210/280=3/4 year3/4 year= 3/4*12 month= 9 months

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted: rectangle with a length of x plus 15 and width of x plus 10 with a rectangle in the bottom right corner labeled bench that has a length of 5 and width of 1
a=(x+20)(x+11)
a=(x+15)(x+10) + 5
a=(x+15)(x+10) - 5
a=(x+9)(x+10)
Answers
Answer:
C
Step-by-step explanation:
A patio=(x+15)*(x+10)
A bench=5*1=5
A painted=A patio-A bench
A painted=(x+15)*(x+10)-5
thus, the answer is C
The painted area is [tex]a=(x+15)(x+10)-5[/tex]. So, option C is correct.
Important information:
Length of rectangular patio is (x+15).Width of rectangular patio is (x+10).Length of bench is 5.Width of bench is 1.Area of rectangle:Area of a rectangle is:
[tex]A=Length \times Width[/tex]
Area of rectangular patio is:
[tex]A_1=(x+15)(x+10)[/tex]
Area of bench is:
[tex]A_2=5\times 1[/tex]
[tex]A_2=5[/tex]
The painting area is:
[tex]a=A_1-A_2[/tex]
[tex]a=(x+15)(x+10)-5[/tex]
Therefore, the correct option is C.

If we are given x such that 25^x-9^y=18 and 5^x-3^y=3, compute 5^x+3^y.
Answers
25 = 5*5 and 9 = 3*3, which we can exploit to write
[tex]25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2[/tex]
so that this expression is actually a difference of squares. We can factorize this to get
[tex](5^x-3^y)(5^x+3^y)=18[/tex]
and given that [tex]5^x-3^y=3[/tex], we divide both sides by this to get
[tex]5^x+3^y=\dfrac{18}3=\boxed{6}[/tex]
