What is the slope of a line that passes through the origin and the point (6, 3)
Answer:
Slope = 1/2
Step-by-step explanation:
Formula for getting slope using 2 points...
(y2 - y1) / (x2 - x1)
= (3 - 0) / (6 - 0)
= 3 / 6
= 1/2
So...
Slope is 1/2
Hope this helps :)
Let me know if there are any mistakes!!
Answer: The slope is 1/2
Step-by-step explanation:
When a line passes through the origin the equation of the line will be represented in the form y= kx where k is the slope.
To to find k you will need to divide both sides by x.
y = kx
y/x = kx/x
k = y/x
This means that to find k, you will need to divide the y coordinate of the point by the x coordinate.
k = 3/6
K = 1/2
A colony of 50 bacteria double in size every 30 minutes. What will the population be 120 mintues from now?
Answer:
800 bacteria
Step-by-step explanation:
Over here, we have exponential growth.
So we have 50 bacteria
Every 30 minutes, it doubles in size
In 120 minutes, there are four 30 minutes.
So you do 50 * 2 * 2 * 2 * 2
Do that out and you get 800

Solve 3X-5 = 9.
Ox= -3
Ox= 2
Ox= 7
OX= 8
NEED HELP ASAP
Answer:
The value of x = 14/3
Step-by-step explanation:
Given the equation
[tex]3x-5 = 9[/tex]
Add 5 to both sides
[tex]3x-5+5=9+5[/tex]
Simplify
[tex]3x=14[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{14}{3}[/tex]
Simplify
[tex]x=\frac{14}{3}[/tex]
Therefore, the value of x = 14/3
Note: It seems you may have missed entering the correct answer choice as the value of x = 14/3 is not mentioned in your answer choices.

A circular button with a diameter of 28 millimeters.
The radius of the button will be 14 millimetres.
What is the radius of the circle?The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.
Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,
Radius = Diameter / 2
Radius = 24 / 2
Radius = 12 millimetres

Answer: m=−3
Step-by-step explanation: −40−2(3m+1/2)=7m−2
−40+(−2)(3m)+(−2)(1/2)=7m+−2
−40+−6m+−1=7m+−2
(−6m)+(−40+−1)=7m−2
−6m+−41=7m−2
−6m−41−7m=7m−2−7m
−13m−41+41=−2+41

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

Si un hombre de 1.75m de altura proyecta una sombra de 3.50m que sombra aproximada proyecta un poste de 8.25m
Answer:
4.25 m
Step-by-step explanation:
Resolvemos esta pregunta usando la fórmula:
Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo
Sombra del hombre = 3.50 m
Altura de un hombre = 1.75 m
Sombra del palo = 8.50 m
Altura del palo = x
Por lo tanto:
1.75 / 3.5 = x / 8.5
Cruz multiplicar
1.75 × 8.5 = 3.5 × x
14.875 = 3.5x
x = 14.875 / 3.5
x = 4.25 metros
Por tanto, la altura del palo = 4.25 m
