Step-by-step explanation:
A line sloping upwards from left to right has a positive gradient.
A line sloping downwards from left to right has a negative slope
If the line crosses the y- axis above the x- axis then y- intercept is positive.
If the line crosses the x- axis below the x- axis then y- intercept is negative.
The line shown slopes downwards from left to right, thus negative gradient
The line crosses the y- axis above the x- axis thus y- intercept is positive

Graph the solution to this inequality on the number line.
0.3(x − 4) > -0.3
Answers
Answer:
Please refer to the attached image in the answer area.
Step-by-step explanation:
The given inequality is:
[tex]0.3(x -4) > -0.3[/tex]
To find:
The graph of inequality on the number line.
Solution:
First of all, let us simplify the inequality.
[tex]0.3(x -4) > -0.3[/tex]
Dividing it with 0.3 on the both sides:
[tex]x -4 > -1\\\text{Adding 4 on both sides}\\\Rightarrow x > 3[/tex]
i.e. all the values x > 3 will be our solution. There is no equal sign in the inequality so 3 will not be included in the solution.
Please refer to the attached image for the solution graph of the given inequality.
3 has an empty circle drawn over it which signifies that 3 is not included in the solution set.
Red line shows that all the values greater than 3 are included in the solution.

Give your answer in hours and minutes.
Answers
Answer:
2:55. That's Two hours and 55 minutes.
Step-by-step explanation: From 8:20 to 11:20 would be three hours. But the actual time is five minutes less. There are 60 minutes in one hour. So change one hour to 60 minutes and subtract 5 minutes.
2:60 - :05 = 2:55
Answer:
2 hours and 55 minutes
Step-by-step explanation:
Take 11:15 and subtract 8:20
11 : 15
-8:20
------------
We need to borrow from the hours
11 becomes 10 and 1 hour = 60 minutes so add 60 to the 15
10 :75
-8:20
------------
2: 55
This is 2 hours and 55 minutes
The altitude of a triangle is 1cm shorter than the base. If the area of the triangle is 15cm2, calculate the altitude.
Answers
Answer:
5 cm
Step-by-step explanation:
We khow that the altitude of this triangle is 1cm shorter than the base
Let H be our altitude and B our base and A the area of the triangleA= (B*H)/2 ⇒ 15=(B*H)/2 H is 1cm shorter than B ⇒ B=H+1H*(H+1)/2=15 ⇒ H*(H+1)=30⇒ H²+H=30⇒H²+H-30+0that's a quadratic equation . Let's calculate the dicriminant .
Let Δ be the dicriminant
a=1b=1c= -30 Δ=b²-4*a*c = 1²-4*1*(-30)=1+4*30=121≥0 Δ≥0⇔ that we have two solutions x and y x= (-1-[tex]\sqrt{121}[/tex])/2= (-1-11)/2= -6 y= (-1+[tex]\sqrt{121}[/tex])/2= 10/2 = 5We have a negative value and a positive one
The altitude is a distance so it can't be negative
H= 5cm

(x + 4)(3x²) + (x + 4)(2x)
The reason why it is + (x + 4) is because the x has a positive sign.

Answer:

x = 121°
Explanation
Angle bottom left corner.
Since the triangle touches a horizontal plane, we know the 2 angles have to add up to 180 degrees.
115 + x = 180
x = 180-115 = 65°
Angle at the top
We know a full circle is 360 degrees.
Let’s say the triangle angle is x
x + 304 = 360
360 - 304 = 56°
Angle of triangle at the bottom right.
We know angles of a triangle add up to 180°.
Since we just calculated the 2 other triangles:
56° + 65° + x = 180
180 - 56 - 65 = 59°
As the triangle sits on a horizontal plane, the angle marked x in the picture + the interior angle have to add to 180.
59° + x = 180
x = 180 - 59 = 121°

Answers
Answer:
We need to find 5 + 10 + 15 + ... + 485 + 490 + 495. There are 99 numbers that are being added. To add this we can do 5 + 495, 10 + 490, 15 + 485 and so on. These pairs have a sum of 500 and since there are 98 / 2 = 49 pairs their sum is 500 * 49 = 24500. Since there is an odd number of numbers that are being added, there is one number that does not belong to a pair. That number is the 50th number in the list which is 50 * 5 = 250. Therefore the answer is 24500 + 250 = 24750.

Identify the slope and y-intercept of each of the following. Please help ^^^^ a. y = x + 100 b. y = 2x - 5 c. y = 0.5x
Answers
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All 3 equations are in this form
(a)
y = x + 100
with slope m = 1 and y- intercept c = 100
(b)
y = 2x - 5
with slope m = 2 and y- intercept = - 5
(c)
y = 0.5x ( or y = 0.5x + 0 )
with slope m = 0.5 and y- intercept c = 0
y-inercept=100
b. y=2x-5
slope=2 y-intercept=5
c. y=0.5x

An ISOSCELES right triangle has a hypotenuse of x√6 units what is the area of the triangle?
Answers
Answer:
x^2/2
Step-by-step explanation:
Alright, lets go.
Isosceles right triangle means a 45-45-90 triangle.
In a 45-45-90 triangle, the hypotenuse is [tex]\sqrt{2}[/tex] times the leg.
Therefore, the length of the leg is x√3.
The area of a triangle is b(h)/2
In a 45-45-90 right triangle, the area is equal to the length of a leg squared/2
A leg = x√3. (x√3)^2 = 3x^2
The area of the triangle is 3x^2/2

A passenger ship and an oil tanker left port sometime in the morning; the former headed north, and the latter headed east. At noon the passenger ship was 40 mi from port and moving at 30 mph, while the oil tanker was 30 mi from port and moving at 20 mph. How fast was the distance between the two ships changing at that time
Answers
Answer:
distance between the two ships changing at that time is 36 mph
Step-by-step explanation:
given data
ship = 40 mi from port
ship moving = 30 mph
oil tanker = 30 mi from port
oil tanker moving = 20 mph
solution
we will apply here pythagoras theorem so we get here
x² + y² = L² .....................1
here x is distance of ship from port
and y is distance of oil tanker from port
and L is distance between oil tanker and ship
so put here value and we get
40² + 30² = L²
L = 50 mile
now we differentiate equation1 with respect to time t
[tex]2x\ \frac{dx}{dt} + 2y\ \frac{dy}{dt} = 2L\ \frac{dL}{dt}[/tex] ...............2
put here value and we get
40 × 30 + 30 × 20 = 50 × [tex]\frac{dL}{dt}[/tex]
[tex]\frac{dL}{dt}[/tex] = 36 mph
so distance between the two ships changing at that time is 36 mph
