1. 3(x - y)
2. 3(9 - -2)
3. 3(9 + 2)
4. 27 + 6
5. 33
[tex]3(x - y)[/tex]
where x = 9 and y = - 2.
Substitute x = 9 and y = -2 in.[tex]3(9 - ( - 2)) \\ 3(9 + 2) = 3(11) \\ 33[/tex]

The hypotenuse of a right triangle is 10 ft long the longer end is 2 ft longer than the shorter leg. Find the side lengths of the triangle
Answer:
The sidelength of the triangles is 6 feet and 8 feet.
Step-by-step explanation:
Given that,
The Hypotenuse of a right triangle = 10 feet
Let the shorter leg is x. It means the longer leg is (x+2).
For a right triangle,
Hypotenuse²=base²+perpendicular²
So,
[tex]10^2=x^2+(x+2)^2\\\\100=x^2+x^2+4+4x\\\\100=2x^2+4x+4\\\\2x^2+4x+4-100=0\\\\2x^2+4x-96=0\\\\x^2+2x-48=0\\\\(x+8)(x-6)=\\\\x=-8,6[/tex]
The side length of a triangle can't be negative. It means that the length of the shorter length is 6 feet and that of the longer leg be 8 feet.

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:
x = 16√3
y = 8√3
Step-by-step explanation:
First, to figure out x, put the side we already know (24) over the cosine of the angle we know (30).
x = 24/cos(30)
(cos(30) is the same as √3/2)
x = 24/√3/2
Step 1: Multiply by 2/√3
x = (24 * 2)/√3
Step 2: Rationalize the denominator by multiplying by √3
x = √3(24 * 2)/√3 * √3
Step 3: √3 squared is 3.
√3(24 * 2)/3
Step 4: Multiply 24 by 2 to get 48.
x = √3(48)/3
Divide √3(48) by 3 to get 16√3
x = 16√3
Before we figure out y, we need to find you what 16√3 squared is.
((16(√3))²
Step 1: Expand the above equation.
16²(√3)²
Step 2: Square 16 to get 256.
256(√3)²
Step 3: √3 squared is 3.
256(3)
Step 4: Multiply 256 by 3 to get 768.
768
Now, subtract 576 (24 squared) from 768 to get 192. Find the square root of that, which is 8√3. (192 = 8² * 3; rewrite as √8²√3, then take the square root of 8²

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
7 years ago father was 7 times as old as his son was. three years hence, he will be three times as old as his son find their present ages.
Answer:
son = 10 , father = 40
Step-by-step explanation:
Let Five years ago the age of son be x years and age of father be 7x years
Present age of son =x+5
Present age of father =7x+5
5 years later their age will (x+10) and (7x+10)
∴7x+10=3(x+10)
7x−3x=20
4x=20
x=5
So, the present age of son=x+5=5+5=10years
and the present age of father=7x+5=35+5=40years

Which of the following expressions could be used to find the perimeter of this figure?
P = 4(18 mm) + 2(24 mm)
P = 18 mm + 24 mm
P = 2(18 mm) + 4(24 mm)
P = (18 mm)(24 mm)
Answer:
A
Step-by-step explanation:
four of the sides are equal to 18mm, so that would be the 4(18mm), and then the two other sides are equal to 24mm, which is 2(24mm). Your full equation would be:
P= 4(18mm) + 2(24mm)
A
Answer:
P = 4(18 mm) + 2(24 mm)

B. As the value of x decreases, the
value of y stays the same.
C. As the value of x increases, the value of y decreases.
D. As the value of x decreases, the value of y decreases.
Answer:
C. As the value of x increases, the value of y decreases.
Step-by-step explanation:
The slope is -3. Negative slope means:
As y increases, x decreases.
Therefore:
As y decreases, x increases.
The coordinates of the vertices of a triangle are G(-4,2), O(5,-1), and T(10,8).
What is the length of the segment joining the midpoint of GT and O?
Answer:
6.33
Step-by-step explanation:
Given the coordinates;
G(-4,2), O(5,-1), and T(10,8).
Midpoint of GT is expressed as;
M = (-4+10/2, 2+8/2)
M = (6/2, 10/2)
M = (3, 5)
Hence the midpoint of GT is (3,5)
Find the length of M and O
M (3,5) and O(5,-1)
MO = √(3-5)²+(5+1)²
MO = √2²+6²
MO = √4+36
MO = √40
MO = 6.33
Hence the length of the segment joining the midpoint of GT and O is 6.33
The length of the segment joining the midpoint of GT and O is 6.33.
The calculation is as follows;Midpoint of GT is expressed as;
[tex]M = (-4+10\div 2, 2+8\div 2)\\\\ = (6\div 2, 10\div 2)[/tex]
= (3, 5)
Hence the midpoint of GT is (3,5)
Find the length of M and O
M (3,5) and O(5,-1)
[tex]MO = \sqrt (3-5)^2+(5+1)^2\\\\= \sqrt(2^2+6^2)\\\\= \sqrt 4+36\\\\= \sqrt 40[/tex]
= 6.33

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.
