See below for the proof that ∠1 and ∠14 are supplementary angles
How to prove that ∠1 and ∠14 are supplementary angles?The attached diagram represents the missing information in the question.
The given parameters are:
∠1 and ∠2 are supplementary angles∠2 = ∠6The next step in the proof is as follows:
∠2 and ∠14 are corresponding angles.
This means that:
∠2 = ∠14
Recall that:
∠1 and ∠2 are supplementary angles
This means that:
∠1 + ∠2 = 180
Substitute ∠2 = ∠14
∠1 + ∠14 = 180
Supplementary angles add up to 180
Hence, ∠1 and ∠14 are supplementary angles

Answer:
y-2x-2
Step-by-step explanation:
The way I would do this is by first using the information given and making an equation in point-slope form, before bringing it to y=mx+b.
We know that the slope is -2, and we have a point, (2,-6). The formula for equations in point slope form is [tex]y-y_{1} =m(x-x_{1} )[/tex]. So, we can insert the given information into this formula to get [tex]y+6=-2(x-2)[/tex].
Next, we distribute the slope to the the parenthesis to get [tex]y+6=-2x+4[/tex]
Then, we subtract 6 from both sides to get [tex]y=-2x-2[/tex]
Since this equation is now in the form [tex]y=mx+b[/tex], the answer is [tex]y-2x-2[/tex]

In a shop, two customers order
Customer 1 pays £3.90 for a tea and two coffees.
Customer 2 pays £4.20 for three teas and a coffee.
How much does one cup of tea cost?
Answers
The cost of a tea cup and a cup of coffee in the shop is £0.90 and £1.50 respectively.
How to write and solve equation?let
x = cost of teay = cost of coffeex + 2y = 3.90
3x + y = 4.20
Multiply (1) by 3 to eliminate x
3x + 6y = 11.70
3x + y = 4.20
5y = 7.50
y = 7.50/5
y = 1.50
Substitute y = 1.50 into (1)
x + 2y = 3.90
x + 2(1.50) = 3.90

Answers
Answer:

Step-by-step explanation:
Given :
y = 64 - 16x²
=========================================================
Add 16x² to each side (take y = 0) :
⇒ 0 + 16x² = 64 - 16x² + 16x²
⇒ 16x² = 64
=========================================================
Divide both sides by 16 :
⇒ 1/16 × 16x² = 1/16 × 64
⇒ x² = 4

Taking square root on both sides :
⇒ √(x²) = √4
⇒ x = ±2

Answer:
Imaginary Roots
Step-by-step explanation:
The quadratic equation ax^2 + bx + c = 0 is written in standard form, and the formula is
x = [-b ± √(b^2 - 4ac)]/ 2a
Given:
3x2 - 4x + 5 = 0'
Here a = 3, b = -4 and c = 5
Substituting:
x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]/ (2 × 3)
Further Simplification:
x = [4 ± √(16 - 60)]/6 ----> Discriminant: b^2 - 4ac = -44 < 0.
x = [4 ± √-44]/ 6
Now, we get:
x = [4 ± 2√-11]/ 6
x = [2 ± i √11]/ 3

Part III: Set up a proportion and solve to find the surface area of the larger solid. (3 points)
Answers
The similarity ratio by taking the cube root of each volume is 8/13, ratio of the surface areas is 64/169, and surface area of the larger solid is 2535 square cm.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
Part 1:
Volume of larger solid = (512) cubic cm
Volume of small solid = 2197 cubic cm
Ratio of the volumes = 512/2197
Taking cube root:
Similarity ratio = 8/13
Part 2:
Similarity ratio by taking the cube root of each volume = 8/13
Taking the square of the above ratio:
= 64/169
Part 3:
64/169 = 960/SA(larger)
SA(larger) = 2535 square cm
Thus, the similarity ratio by taking the cube root of each volume is 8/13, ratio of the surface areas is 64/169, and surface area of the larger solid is 2535 square cm.

if d1 = d2 then you get 20+50t = 70t as your working equation.
20 + 50t = 70t Subtract 50t from both sides
20 +50t-50t = 70t-50t Combine

2a + 3b = 48 equation 2
Where:
a = cost of 1 shirt b = cost of one pair of shoesWhat is the cost of one pair of shoes?Subtract equation 1 from equation 2
2b = 16
b = 16/2
b = $8
What is the cost of one shirt?
Substitute for b in equation 1
2a + 8 = 32
2a = 32 - 8
2a = 24
