Answer:
I think it's 3
Step-by-step explanation:
To calculate the gradient equals to
y(1)-y(2)
-----------
x(1)-x(2)
So - 5 - 1 = - 6
6 - 2 = 4
-6 - 3
--- = ----- x
4 2
And the first y intercept is 1 so I guess it's 3.
Just for refernece, not sure if I'm correct. Sry
Answer:
Number 2 is the answer.
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
y - 1 = -3/2(x - 2)
y - 1 = -3/2x + 3
+1 +1
y = -3/2x + 4

Equation of parallel line:
Answers
Answer:
a)The equation of the Parallel line to the given line is
7x -y +18 =0
b) The equation of the Perpendicular line to the given line is
-x +7y +18 =0
Step-by-step explanation:
Step(i):-
Given that equation of the line y = 7x -5
7x -y -5=0
The equation of the Parallel line to the given line is
7x -y +k=0
This line is passes through the point ( -3,-3)
7 ( -3) -(-3)+k=0
-21 +3+k=0
-18 +k=0
k =18
The equation of the Parallel line to the given line is
7x -y +18 =0
Step(ii):-
Given that equation of the line y = 7x -5
7x -y -5=0
The equation of the perpendicular line
b x -ay +k=0
The equation of the Perpendicular line to the given line is
-x +7y +k=0
This line is passes through the point ( -3,-3)
-(-3)+7(-3) +k=0
3 - 21 +k=0
-18 +k=0
k =18
The equation of the Perpendicular line to the given line is
-x +7y +18 =0
the triangle and the trapezoid have the same base area. Base b2 is twice the area the length of b1. What are the lengths of the bases of the trapezoid?
Answers
Answer: b₁ = 7 and b₂ = 14.
Triangle: base=21 cm, height=6cm
Trapezoid: height=6 cm, b1=?, b2=?
Triangle -> A=bh/2 -> A=63 (b is base and h is height)
Trapezoid -> A=[(b₁+b₂)/2)]h (b₁ and b₂ are bases and h is height)
Since they have the same area, the formula will be:
63=[(b₁+2(b₁))/2)]h
x=7
Answer:
b₁ = 7 cm, b₂ = 14 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 21 and h = 6, then
A = 0.5 × 21 × 6 = 63 cm²
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
Here A = 63 ( same as triangle ), h = 6 and b₂ = 2b₁ , then
0.5 × 6 × (b₁ + 2b₁ ) = 63
3 × 3b₁ = 63
9b₁ = 63 ( divide both sides by 9 )
b₁ = 7
and b₂ = 2 × 7 = 14
The bases of the trapezoid are 7 cm and 14 cm
Triangles
• If one side of a triangular piece of yard area is roughly one-third the perimeter,
the second side is roughly one-fifth the perimeter, and the third side is 7yards,
what is the perimeter of the triangle?
Answers
Answer:
15m
Step-by-step explanation:
The third side = (2/3 - 1/5) of the perimeter = 7/15 of the perimeter = 7m
The first side is 1/3 (=5/15) of the perimeter = 5m
The second side is then 3m ( or 1/5=3/15 of the perimeter).
The triangle perimeter is 15 meters (=7 m+5m+3m)
find what y and x equals
y=-2x
y=2x-1
Answers
Answer:
The correct answer is "[tex]x=\frac{1}{4}[/tex]" and "[tex]y=-\frac{1}{2}[/tex]"
Step-by-step explanation:
As we know,
y = -2x ...(equation 1)
y = 2x-1 ...(equation 2)
On putting the value of "equation 1" in the "equation 2", we get
⇒ [tex]y=2x-1[/tex]
⇒ [tex]-2x=2x-1[/tex]
On adding "2x" both sides, we get
⇒ [tex]-2x+2x=2x-1+2x[/tex]
⇒ [tex]0=4x-1[/tex]
⇒ [tex]4x=1[/tex]
⇒ [tex]x=\frac{1}{4}[/tex]
Now,
On putting the value of "x" in equation 1, we get
⇒ [tex]y=-2x[/tex]
⇒ [tex]y=-2\times \frac{1}{4}[/tex]
⇒ [tex]y=-\frac{1}{2}[/tex]

Determine two coterminal angles (one positive and one negative) for each angle. Give your answer in radians. (Enter you answer as a comma-separated list)
Answers
Answer:
The answer is below
Step-by-step explanation:
Coterminal angles are angles with the same terminal side at standard position (angles with the initial side on the positive x-axis). Coterminal angles may have different magnitude but they would have equal sides and vertices.
Coterminal angles can either be positive or negative. The positive coterminal is gotten by adding 2π rad or 360° while the negative coterminal is gotten by subtracting 2π rad or 360°.
a)
Positive coterminal angle = [tex]\frac{5\pi}{4}+2\pi=\frac{13\pi}{4} \ rad[/tex]
Negative coterminal angle = [tex]\frac{5\pi}{4}-2\pi=\frac{-3\pi}{4} \ rad[/tex]
b)
Positive coterminal angle = [tex]\frac{-9\pi}{4}+2\pi=\frac{-\pi}{4}+2\pi=\frac{7\pi}{4} \ rad[/tex]
Negative coterminal angle = [tex]\frac{-9\pi}{4}-2\pi=\frac{-17 \pi}{4} \ rad[/tex]

constant of proportionality: k = y/x
- plug in numbers to find:
k = 84.45 / 5
= 16.89
so, constant of proportionality: 16.89
equation:
y = kx (now plug in)
y = 16.89x
- plug in again to find the amount of cakes
y = 16.89x
895.17 = 16.89x
x = 53
