What is an equation of the line that passes through the points (6,0) and (−1,−7)
Answer: y= 1x - 6
Step-by-step explanation:
(6,0) (-1,-7)
0-(-7)= 7
6-(-1)= 7
7/7= 1 so the slope is 1 and we just need to find the y-intercept and we will do that by using the formula y= mx +b
-7= 1(-1) + b
-7= -1 + b
+1 + 1
b= -6 so the y-intercept is -6.
Answer:
y= 1x - 6

A regular hexagon and a regular octagon are joined as shown on the diagram
Work out the size of angle x
Answer:
x = 105°
Step-by-step explanation:
The shape above is a regular hexagon and a regular octagon the both of them have the same interior angle through out. For a polygon to be regular all it interior angle are the same .
sum of interior angles of a polygon = (n - 2)180°
where
n = number of sides
Therefore,
sum of interior angle of a hexagon = (6 - 2)180
sum of interior angle of a hexagon = (4)180
sum of interior angle of a hexagon = 720
each angle of a regular hexagon = 720/6 = 120°
sum of interior angles of an octagon = (8- 2)180
sum of interior angles of an octagon = (6)180
sum of interior angles of an octagon = 1080
each angle of a regular octagon = 1080/8 = 135°
All the angle around a point add up to 360°. So if we take the interior angle from 360° we will get angle x
360 - (135° + 120°)
360 - 255
x = 105°
Answer:
105
Step-by-step explanation:

19 + 12k = –k − 20 solve for k
Answer:
k=13
Step-by-step explanation:
19 + 12k = –k − 20
19+20=39=13k
k=13
Answer: -3
Step-by-step explanation:
Let's solve your equation step-by-step.
19+12k=−k−20
Step 1: Simplify both sides of the equation.
19+12k=−k−20
19+12k=−k+−20
12k+19=−k−20
Step 2: Add k to both sides.
12k+19+k=−k−20+k
13k+19=−20
Step 3: Subtract 19 from both sides.
13k+19−19=−20−19
13k=−39
Step 4: Divide both sides by 13.
13k /13 = −39/13
answer choices :
A : x = - 5
B : x = - 4
C : x = 4
D x = 5
Answer:
x=-4
Step-by-step explanation:
[tex]\frac{1}{4} x - \frac{1}{8} = \frac{7}{8} + \frac{1}{2} x[/tex]
first group the like terms
[tex]\frac{1}{4} x - \frac{1}{2}x = 1[/tex]
as 1/8 plus 7/8 = 1
then add the x's together
[tex]-\frac{1}{4} x = 1[/tex]
and finally
x = -4

Find the diameter of each circle.
Answer:
Diameter Length: ( About ) 5.4 km; Option B
Step-by-step explanation:
~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~
1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒
radius = ( About ) 2.7
2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km
Diameter Length: ( About ) 5.4 km

You are stacking wooden blocks (cubes) whose sides are all 1 1/4 inches how many blocks do you need to stack or build a block tower that is 7 1/2 inches tall
Answer: You need to stack 6 blocks to build the block tower.
Step-by-step explanation:
Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).
Mathematically speaking:
7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes
You need to stack 6 blocks to build the block tower.

Which set of ratios could be used to determine if one triangle is a dilation of the other?
A triangle with side lengths 3.6, 5.4, 6. A triangle with side lengths 3, 4.5, 5.
StartFraction 3.6 Over 3 EndFraction = StartFraction 5.4 Over 4.5 EndFraction = StartFraction 6 Over 5 EndFraction
StartFraction 3.6 Over 3 EndFraction = StartFraction 4.5 Over 5.4 EndFraction = StartFraction 6 Over 5 EndFraction
StartFraction 3 Over 3.6 EndFraction = StartFraction 4.5 Over 6 EndFraction = StartFraction 5 Over 5.4 EndFraction
StartFraction 3 Over 4.5 EndFraction = StartFraction 3.6 Over 5.4 EndFraction = StartFraction 5 Over 6 EndFraction
Answer:
Option (1).
Step-by-step explanation:
Dimensions of two triangles have been given as 3.6, 5.4, 6 units and 3, 4.5, 5 units.
If triangle one is dilated to form triangle two, then the ratio of the sides will be
Ratio = [tex]\frac{\text{Side of triangle (1)}}{\text{Corresponding side of triangle (2)}}[/tex]
= [tex]\frac{3.6}{3}[/tex]
Similarly, ratio of other two sides will be = [tex]\frac{5.4}{4.5}[/tex] and [tex]\frac{6}{5}[/tex]
Since the triangle (1) was dilated to form triangle (2), so both triangles will be similar and the ratios of their corresponding sides will be equal.
Therefore, Ratios of the sides = [tex]\frac{3.6}{3}=\frac{5.4}{4.5}=\frac{6}{5}[/tex]
Option (1) will be the answer.
Answer:
StartFraction 3.6 Over 3 EndFraction = StartFraction 5.4 Over 4.5 EndFraction = StartFraction 6 Over 5 EndFraction

Quadrilateral A^ prime B^ prime C^ prime D^ prime is the image of quadrilateral ABCD under a rotation about point Q
A: -90
B: -60
C: 60
D: 90
When a shape is rotated, it must be rotated through a point.
The rotation from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex] is (d) [tex]90^o[/tex]
To determine the angle of rotation from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex], we use the following steps

From the attached image;
We draw A and A' to point QThen we measure the angle at Q; this gives [tex]90^o[/tex].The arrow from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex] indicates a clockwise directionHence, the angle of rotation is D: 90

The length and breadth of a rectangular shaped plot is 1215 m and 527 m respectively. Find its perimeter.
Answer:
3484m
Step-by-step explanation:
Perimeter of a rectangle= 2(L+B) where L= Length and B= Breadth
Length of the plot= 1215m
Breadth= 527m
∴ Perimeter of the plot= 2(1215m+527m)
= 2(1742m)
= 3484m

The profits of Mr. Cash's company is represented by the equation 푃 푡 =−3푡 ) +18푡−4, where 푃(푡) is the amount of profit in hundreds of thousands of dollars and 푡 is the number of years of operation. He realizes his company is on the down turn and wishes to sell before he ends up in debt.
Answer:
- Mr Cash's company business shows the maximum profit in 3 years after starting the business.
- The maximum profit = 23 thousand dollars = $23,000
- Anytime beyond 5.77 years will be too late to sell the business as the profit margins have entered negative values.
Step-by-step explanation:
Complete Correct Question
The profits of Mr. Cash’s company is represented by the equation
p(t)=-3t^2+18t-4,
where p(t) is the amount of profit in hundreds of thousands of dollars and t is the number of years of operation. He realizes his company is on the down turn and wishes to sell before he ends up in debt.
In what year of operation does Mr. Cash’s business show maximum profit? What is the maximum profit? What time will it be too late to sell business?
Solution
The profit function is given as
p(t) = -3t² + 18t - 4
p(t) = profit in thousand of dollars
t = time in years.
To find the year where the maximum profit is obtained, we use differentiation analysis to obtain the maximum of the profit function and the corresponding time where it occurs.
At the maximum of the profit function,
(dp/dt) = 0 and (d²p/dt²) < 0
p(t) = -3t² + 18t - 4
(dp/dt) = -6t + 18
At maximum profit
(dp/dt) = -6t + 18 = 0
6t = 18
t = (18/6) = 3 years.
(d²p/dt²) = -6 < 0
Hence, this value of t corresponds to the maximum value of the profit function.
The maximum profit is then obtained when t = 3
p(t) = -3t² + 18t - 4
p(3) = -3(3²) + 18(3) - 4 = 23 thousand dollars
The business will be late to sell when the profits from the business start to run into negative values. So, we obtain the time when the profit margins reaches 0.
p(t) = -3t² + 18t - 4 = 0
-3t² + 18t - 4 = 0
Solving the quadratic equation
t = 0.23 years or t = 5.77 years
Since the profits first start rising from the value at t=0 up till the maximum profit at t=3, 0.23 years isn't a realistic point to sell the business as this is part of the onset of profits, but beyond 5.77 years on the other hand represents when the business stops to bringing in profits and leads to losses.
