Answer:
y-4=4/5*(x+6)
Step-by-step explanation:
First you need to find the vaules for y-y₁=m(x-x₁) point slope form
y1 =4
x1=-6
m=4/5( because thats the slope)
Second plug in:
y-4 = 4/5(x+6)
done easy peesy :)
34 is 50% of what number?
Select two correct slope and y-intercept for the equation: y = -5x + 6
m = 5
m = -5
m = 6
m = -6
b = 5
b = -5
b = 6
b = -6
Answer:
m=-5
b=6

Write an equation of the line that passes through (3,2) and is perpendicular to the line y= 1/3x-3
Answer:
y = - 3x + 11
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 )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line

Is it possible for the function f(x) - 5 x 2^x to have an output of 200?
Answer:
The solution is possible
Step-by-step explanation:
Given
[tex]f(x) = 5 * 2^x[/tex]
Required
Is an output of 200, possible?
To know if it is possible or not, we start by substituting 200 for f(x)
[tex]200 = 5 * 2^x[/tex]
Divide both sides by 5
[tex]\frac{200}{5} = \frac{5}{5} * 2^x[/tex]
[tex]\frac{200}{5} = 2^x[/tex]
[tex]40 = 2^x[/tex]
[tex]2^x =40[/tex]
Take logarithm of both sides
[tex]log2^x =log40[/tex]
Apply law of logarithm
[tex]xlog2 =log40[/tex]
Divide both sides by log2
[tex]x = \frac{log40}{log2}[/tex]
[tex]x = \frac{1.6021}{0.3010}[/tex]
[tex]x = 5.32[/tex]
for f(x) = 200, x is approximately 5.32
Hence, the solution is possible

Halla la suma de los infinitos términos de la progresión geométrica si r= 1/5 y a1=1/2
Answer:
5/8
Step-by-step explanation:
Aquí, queremos encontrar la suma al infinito de la progresión geométrica, dado el primer término y la razón común Matemáticamente, eso sería;
S = a/1-r
S = 1/2/(1-1/5)
S = 1/2/4/5
S = 1/2 * 5/4
S = 5/8
A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling

You are 18 miles away from home. You start biking home at a speed of 6 miles per hour. Write an equation in slope-intercept form that represents the distance away from home "y" after "x" hours. Y= How many hours will it take to get home? Hours
Answer:
y = 18 - 6x
Step-by-step explanation:
Given :
Speed or rate = 6mph
y = distance away from home
x = hours biked
Initial distance from home = 18 miles
General form of Slope - intercept form of an equation :
y = mx + c
Where ;
m = gradient or slope = rate of change
c = intercept or initial value or amount, always constant
x = independent variable
y = dependent variable
Hence,
For the question above :
Distance away from home, depends on the number of hours biked
y = 18 - 6x

Which size Dairy Queen blizzard gives you the best price per ounce
Small 6oz. Cup for $2.49
Large 16oz. Cup for $4.98
Medium 10oz. Cup for $3.49
Supper size 24oz. Cup for 7.69
The Large blizzard has the lowest cost per ounce at $ 0.31125/oz
Given data ,
To determine the best price per ounce for Dairy Queen blizzards, we can calculate the cost per ounce for each size option:
Small: 6 oz. for $2.49 ->
Cost per ounce = $2.49 / 6 oz. = $0.415/oz.
Large: 16 oz. for $4.98 ->
On simplifying the equation , we get
Cost per ounce = $4.98 / 16 oz. = $ 0.31125/oz.
Medium: 10 oz. for $3.49 ->
Cost per ounce = $3.49 / 10 oz. = $0.349/oz.
Super Size: 24 oz. for $7.69 ->
On simplifying the equation , we get
Cost per ounce = $7.69 / 24 oz. = $0.32042/oz.
Comparing the cost per ounce for each size option, we can see that the Small blizzard has the highest cost per ounce at $0.415/oz. The Large blizzard has the lowest cost per ounce at $ 0.31125/oz.
Hence , the Large blizzard gives you the best price per ounce among the options provided.

The sales tax on clothing that cost $24 is $1.68. How much would sales tax be on clothing that cost $96?
Answer:
$6.72
Step-by-step explanation:
1.68 is 7% of 24, so there is a 7% tax.
96x.07= 6.72
Answer: The sales tax would be 6.72
Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72
There are 32 sticks in the game. The sticks are either orange (x) and red (y). There are 5 more red sticks than twice the number of orange sticks Write the two equations in order to solve the system and then tell me how many orange and red sticks are in the game.
Answer:
orange = 9 sticks
Red = 23 sticks
Step-by-step explanation:
orange = x
Red = y
x + y = 32
There are 5 more red sticks than twice the number of orange sticks
y = 2x + 5
x + y = 32
x + 2x + 5 = 32
3x = 32 - 5
3x = 27
x = 27/3
x = 9 sticks
y = 2x + 5
= 2(9) + 5
= 18 + 5
y = 23 sticks
orange = 9 sticks
Red = 23 sticks
A construction crew has just finished building a road. The crew worked for 4 1/5 days. If they built 2 1/3 kilometers of road each day, what is the total length of road they built?
Answer:
9.8
Step-by-step explanation:
The crew worked for 4 1/5 days
They built 2 1/3 kilometres of road each day
Therefore the total length of the road can be calculated as follows
= 4 1/5 × 2 1/3
= 21/5 × 7/3
= 147/15
= 9.8
Hence the length of the road is 9.8 kilometres

A bird starts at 20m and changes to 16m? The bird's final elevation is
Answer:
Kindly check explanation
Step-by-step explanation:
The initial elevation is 20m
According to the question :
If it changes to 16m, then the final elevation of the bird is 16 m.
However, in some texts, the question goes thus;
A bird starts at 20m and changes 16m? The bird's final elevation is?
In this case, the initial height = 20m
Change in height = 16 m (positive means ascension)
Hence,
initial height + change in height
20 m + 16 m
= 36m

recipe is 14:12. Which ratio is equivalent to 14:12?
Answer:
7:6
Step-by-step explanation:
I simplified 14:12
Step-by-step explanation:
Since 14 and 12 are both even numbers, they are a multiple of 2.
14 = 2 * 7
12 = 2 * 6
Therefore 14:12 = (2*7):(2*6) = 7:6.
The equivalent ratio is 7:6.

Find all values of x that make the triangles congruent. Explain your reasoning.
Answer:
The values of x that make the triangles congruent.
x = 6 and x = 3
Step-by-step explanation:
Given
AC = 5x-2DC = 3x+10AB = 5xDB = 4x+3Given that the triangles are congruent.
According to the SAS (Side-Side-Side)
AC = DC
AB = DB
so
AC = DC
substituting AC = 5x-2 and DC = 3x+10
5x-2 = 3x+10
5x-3x = 10+2
2x = 12
divide both sides by 2
2x/2 = 12/2
x = 6
and
AB = DB
substituting AB = 5x and DB = 4x+3
5x = 4x+3
5x-4x = 3
x = 3
Therefore, the values of x that make the triangles congruent.
x = 6 and x = 3
