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?
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
The graph of which equation is shown?
Answer:
it should be
C. y = 2x +2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The starting point is 2. Where the line touches the y axis. The line as you see is going down which is negative. Pick 2 points on the graph where it’s touching. It is going down by 2. Hope this helps!

Step-by-step explanation:
find what y and x equals
y=-2x
y=2x-1
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]

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
53 cakes

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)
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]

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?
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)

3x - 5y = 22
y = -5x + 32
Answer:
x = ¹³⁄₂
y = ⁻¹⁄₂
Explanation:
[tex]\bold{\begin{bmatrix}3x-5y=22\\ y=-5x+32\end{bmatrix}}[/tex]
Substitute y = -5x + 32[tex]\bold{\begin{bmatrix}3x-5\left(-5x+32\right)=22\end{bmatrix}}[/tex]
Simplify[tex]\bold{\begin{bmatrix}28x-160=22\end{bmatrix}}[/tex]
Isolate x for 28x - 160 - 22: x = ¹³⁄₂[tex]\bold{\mathrm{For\:}y=-5x+32}[/tex]
Substitute x = ¹³⁄₂[tex]\bold{y=-5\cdot \frac{13}{2}+32}[/tex]
-5 · ¹³⁄₂ + 32 = ⁻¹⁄₂
y = ⁻¹⁄₂x = ¹³⁄₂
y = ⁻¹⁄₂

Equation of parallel line:
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
