Is the picture below a graph for the following inequality? Why or why not?
y<6x+1
Given picture is not a graph of inequality y < 6x + 1
In this question, we have been given a graph.
We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.
We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.
This graph represents a shaded region below dotted line. This means, this is the graph of inequality.
From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)
If we find the x and y-intercept of y = 6x + 1 then it would be,
x - intercept = (-1/6 , 0)
y - intercept = (0, 1)
This means, given picture is not a graph of inequality y < 6x + 1
Therefore, given picture is not a graph of inequality y < 6x + 1

The points ( – 5,j) and (5, – 6) fall on a line with a slope of – 7/10 . What is the value of j?
Answer:
j = 1
Step-by-step explanation:
calculate the slope m between the 2 points and equate to - [tex]\frac{7}{10}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, j ) and (x₂, y₂ ) = (5, - 6 )
m = [tex]\frac{-6-j}{5-(-5)}[/tex] = [tex]\frac{-6-j}{5+5}[/tex] = [tex]\frac{-6-j}{10}[/tex]
then equating gives
[tex]\frac{-6-j}{10}[/tex] = - [tex]\frac{7}{10}[/tex] ( cross- multiply )
10(- 6 - j) = - 70 ( divide both sides by 10 )
- 6 - j = - 7 ( add 6 to both sides )
- j = - 1 ( multiply both sides by - 1 )
j = 1
An egg of a particular bird is very nearly spherical. The radius to the inside of the shell is 4 millimeters and the radius to the outside of the shell is 4.3 millimeters. Use differentials to approximate the volume of the shell. [Remember that V(r) =
#x p3, where r is the radius.]
If the radius to the inside of the shell is 4 millimeters and the radius to the outside of the shell is 4.3 millimeters. the volume of the shell is 19π mm³.
Volume of the shellv = 4 / 3πr³
dv =4 / 3π (3r²) dr
Where:
r= radius = 4 cm
dr = 4.3 -4 = 0.3
Hence,
dv = 4 / 3π (16) 3/10
dv =4 / 3π(16) 0.3
dv = 19.2π mm³
dv = 19π mm³ (Approximately)

Fae is following a recipe to make dough. The amount of water (in ounces) she uses depends on the amount of flour she uses (in cups). The amounts for each ingredient are shown in the graph.
The unit rate of ounces of water per cup of flour for this situation is; 3 ounces per cups
What is the unit rate of the graph?
From the given graph, we are expected to find the unit rate of ounces of water per cup of flour for the situation.
Now, to find the unit rate , all we need to do is to pick two coordinates on the line graph and find the slope. Thus;
Slope = (y2 - y1)/(x2 - x1)
Slope of graph = (12 - 9)/(4 - 3)
Slope = 3/1
Slope = 3

It is to be noted that the information for the completed table is given accordingly to show the perimeters in millimeters and in centimeters.
What is a Perimeter?Perimeter simply refers to the total or sum of all the sides of a geometric shape. Note that the perimeter in units is obtained by counting the number of rectangles.
In the case of A:
Perimeter in Units = 10 Units.
Length is 60mm and width is 40mm
Perimeter = 30 + 20 + 30 + 20 = 100mm; and 10 cm
Recall that I cm = 10mm.
Hence, 100 /10 = 10 cm.
In the case of shape B:
Perimeter in Units = 41 Units.
Length is 400mm (that is 200 + 200)
Breath is 40mm (20 + 20)
Perimeter therefore is:
400 + 40 = 440mm
Perimeter in cm = 44
Recall, 10mm = 1cm
In the case of shape C:
Perimeter in Units = 36 Units.
Length is 10cm (that is 5 + 5)
Breath is 14mm (7 + 7)
Perimeter therefore is:
10+ 14 = 24cm
Perimeter in mm= 240
Recall, 10mm = 1cm
In the case of Shape D:
Perimeter in Units = 51 Units.
Length is 200mm (that is 100 + 100)
Breath is 100mm (50 + 50)
Perimeter therefore is:
200 + 100 = 300mm
Perimeter in cm= 230
Recall, 10mm = 1cm
In the case of Shape D:
Perimeter in Units = 53 Units.
Length is 260mm (that is 130 + 130)
Breath is 80mm (40 + 40)
Perimeter therefore is:
260 + 80 = 340mm
Perimeter in cm= 34

The point (-4,1) is rotated 180 degrees counterclockwise using center (-3,0). What are the coordinates of the image?
By using a rotation rule, the image of point P = (- 4, 1) after rotating 180° counterclockwise using center (- 3, 0) is equal to point P'(x, y) = (- 2, 1).
How to determine the coordinates of the image of a point by using a transformation ruleIn this problem we find the case of a point that must be rotated 180° counterclockwise (+ 180°) about the point (- 3, 0). Rotation is a kind of rigid transformation, that is, a kind of transformation applied on a point such that Euclidean distance is conserved. The rotation formula for a point P(x, y) = (x, y) around the center O(x, y) = (Ox, Oy) is introduced below:
P'(x, y) = (Ox + (x - Ox) · cos θ - (y - Oy) · sin θ, Oy + (x - Ox) · sin θ + (y - Oy) · cos θ)
Where θ is the angle of rotation.
If we know that O(x, y) = (- 3, 0), P(x, y) = (- 4, 1) and θ = 180°, then the coordinates of the image are:
P'(x, y) = (- 3 + [- 4 - (- 3)] · cos 180° - (1 - 0) · sin 180°, 0 + [- 4 - (- 3)] · sin 180° + (1 - 0) · cos 180°)
P'(x, y) = (- 3 - [- 4 - (- 3)], - 1)
P'(x, y) = (- 3 - (- 1), - 1)
P'(x, y) = (- 2, - 1)
The coordinates of the image are P'(x, y) = (- 2, 1).

2 Find x and y
130⁰ answer
Answer: x = 80°, y = 50°
Step-by-step explanation:
We have an isosceles triangle.
As you can see, 130° lies on a straight line. A straight line = 180°.
The base angles of an isosceles triangle are equal. This means 180° - 130° = y.
So, y = 50°.
The total measures of any triangle is 180 degrees.
The total measure for the base angles here 100 degrees. That is, 50° + 50° =
100°.
How do we find x?
x = 180° - 100
x = 80°

Answer: See attached and/or view below.
Step-by-step explanation:
Since we are given the equation, we can plug the values into it and solve for the unknown. We will solve by isolating the variable and using reverse operations.
x = 1, y = 34
2x + y = 36
2(1) + y = 36
2 + y = 36
y = 34
x = -2, y = 40
2x + y = 36
2(-2) + y = 36
-4 + y = 36
y = 40
y = 18, x = 9
2x + y = 36
2x + (18) = 36

Since angle measure 3 was found, seeing that 3 and 1 are vertical angles (congruent) they equal the same, meaning angle measure 1 is also 159°. Also seeing that angle measure 3 and 2 are supplementary angles (2 or more angles that add up to 180°) subtracting 159° will give you 21°.
