Answer:
Infinitely many solutions.
Step-by-step explanation:
Multiply the second equation by -2, then add the equations together
(20x+2y=18)
−2(10x+y=9)
20x+2y=18
−20x−2y=−18
Add these equations to eliminate x
0=0
Infinitely many solutions.
Which inequality represents the stated situation : A theater is made to receive no more than 750 spectators. Group of answer choices
Answer:
C. s ≤ 750
Step-by-step explanation:
A. s≥750
B. s=750
C. s≤750
D. s<750
'no more than' in inequality means "less than or equal to"(≤) which means that the quantity could be less than or equal to.
From the question given, the theater can only receive less than 750 spectators or 750 spectators but no more than 750 spectators
The statement can be represented by the inequality;
s ≤ 750
Where
s means spectators

Write the equation of the line perpendicular to y = 6/5x + 4/5 that passes through the point (-3,2).
Answer:
The equation of the perpendicular line of the given line is
[tex]y = \frac{-5}{6} x -\frac{1}{2}[/tex]
Step-by-step explanation:
Step(i):-
Given the equation of the line
[tex]y = \frac{6}{5} x + \frac{4}{5}[/tex]
cross-multiplication, we get
5y = 6x +4
The equation of the straight line is 6x - 5y +4=0
The equation of the perpendicular line to the given line is
b x - ay +k=0
The equation of the perpendicular line to the given line is -5x-6y +k=0
This line passes through the point (-3,2)
⇒ - 5(-3) -6(2)+k=0
⇒ 15 -12 +k=0
⇒ 3 +k=0
⇒ k =-3
Step(ii):-
The equation of the perpendicular line is
-5x-6y-3=0
5x + 6y +3 =0
6y = -5x-3
[tex]y = \frac{-5}{6} x -\frac{3}{6}[/tex]
Final answer:-
The equation of the perpendicular line of the given line is
[tex]y = \frac{-5}{6} x -\frac{1}{2}[/tex]

Answer:
y= -2/3x +4
Step-by-step explanation:
(0,4) and (6,0)
m= (y2-y1)/(x2-x1)
m= (0-4)/(6-0)
m= -2/3
y-y1=m(x-x1)
y-4= -2/3(x-0)
y-4= -2/3x
y= -2/3x +4
Answer:
D
Step-by-step explanation:
Almost positive it's D. When you take two points on the line, you'll get a slope of 2/3. Since it's going down left to right, it's going to be negative. SOOO -2/3. The y-intercept is 4 because, well that's where the line crosses the y-axis.

rewrite sin^4x that involves only the first power of cos
Answer:
We want to rewrite:
sin^4(x)
in a way that only involves the first power of the cosine function.
We know that:
sin^2(x) = 1 - cos^2(x)
Then:
sin^4(x) = sin^2(x)*sin^2(x) = sin^2(x)*(1 - cos^2(x))
Now we know that:
cos(2x) = cos^2(x) - sin^2(x)
then
cos(2x) + sin^2(x) = cos^2(x)
We can replace that in our equation to get:
sin^2(x)*(1 - cos^2(x)) = sin^2(x)*(1 - cos(2x) - sin^2(x) )
sin^2(x)*(1 - cos(2x) - sin^2(x) ) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)
then:
sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)
sin^4(x) + sin^4(x) = sin^2(x) - sin^2(x)*cos(2x)
2*sin^4(x) = sin^2(x) - sin^2(x)*cos(2x) = sin^2(x)*(1 - cos(2x))
sin^4(x) = sin^2(x)*(1 - cos(2x))/2
So we rewrite the equation in such a way that we only have the first power of the cosine function.

=> X - 2 = -8
=> X=(-6) - 2
=> -8
Answer:
x = -6
Step-by-step explanation:
x - 2 = -8
Add 2 to both sides to isolate the variable, x.
x - 2 + 2 = -8 + 2
-2+2 = 0
-8+2 = -6
Therefore,
x = -6
Check:
-6 -2 = -8

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Answer:
$36.38
Step-by-step explanation:
If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Given data
Tax= 7%
Cost = $34
Let us solve for the amount of tax
=7/100*34
=0.07*34
=2.38
Hence the total is =2.38+34
=$36.38

A scale drawing of a house shows 9cm x10cm. If
6cm=12 ft, what are the actual dimensions?
Answer:
18ft x 20ft
Step-by-step explanation:
(I'm kinda in a rush so I can't explain right now, sorry!)
Hope that helped though :)
The actual dimensions of the house is 18 feet by 20 feet.
Scaling is used to either increase or decrease the size of a figure to create an image.
Given that a scale of 6cm to represent 12 ft. Hence:
9 cm = 9 cm * (12 ft. per 6 cm) = 18 feet.
10 cm = 10 cm * (12 ft. per 6 cm) = 20 feet.
The actual dimensions of the house is 18 feet by 20 feet.
