Identify an equation in point slope form for the line perpendicular to
y = -4x - 1 that passes through (-2,7).

Answers

Answer 1
Point slope form is y2-y1=m(x2-x1).

The slope m that is perpendicular to y=-4x-1 will be 1/4 (the opposite reciprocal). Then you can use (-2,7) as the x and y values to plug into the formula:

y-7=1/4(x+2) is the answer.

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel

help pls asap ty ! ! !

Answers

Answer:

They intersect

Step-by-step explanation:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.

Here we have two functions:

1) y = 4x + 2

2) 8x + 2y = - 3

   2y = - 8x - 3

   // divide both sides by 2

   y = - 4x - 1,5  

- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

How would I find the difference of 7/8 - 1/3 ?

Answers

Answer:

[tex]\frac{13}{24}[/tex]

Step-by-step explanation:

We have two fractions and are being asked to subtract them.

7/8 and 1/3 don't have the same denominator, so to do as so, we need to find the LCM of both denominators, multiply them to that, and do the same for the numerators.

So what is the LCM (Least Common Multiple) of 8 and 3?

24.

Therefore :

[tex]\frac{7 * 3}{8 * 3} - \frac{1*8}{3*8}[/tex]

[tex]\frac{21}{24} - \frac{8}{24}[/tex]

[tex]\frac{13}{24}[/tex]

Answer:

13/24

Step-by-step explanation:

1. Common denominator:

common denominator = 24

multiply bottom and top so from 8 to 24 is 8x3, so multiply by three and what you do to the bottom you do to the top so,

7/8: 8 x 3 = 24 and 7 x 3 = 21 so the new fraction is 21/24.

Do the same to the other fraction: 1/3 multiply top and bottom by 8 because 3 x 8 = 24.

1/3 = 8/24

Now just subtract:

21/24 - 8/24 = 13/24 (There is your answer)

The simplified base for the function given is 9.

What is a function?

A function in math is a rule or expression that defines a relationship between one variable (the input or independent variable) and another variable (the output or dependent variable). A function assigns to each input exactly one output.

Given that, a function f(x) = 2(∛27)²ˣ, we need to find its simplest base,

So,

f(x) = 2(∛27)²ˣ

= 2(3)²ˣ [∵ 3³ = 27, ∴ ∛27 = 3]

= 2(3²)ˣ

= 2(9)ˣ

Hence, the simplified base for the function given is 9.

Your x-intercept would be E, -4

Step-by-Step

To find the x-intercept, set  y=0.

Our problem:

y=5x+20

0=5x+20

To get the variable term on its own you need to move your 20 over by subtracting it from the right and moving to the left making it -20.

-20=5x

Divide by 5 to get x on its own

-20/5= 5x/5

Jia has $44,000 in a savings account. The savings collect interest at a 6% annual rate that compounds every year. How much money will be in Jia's account after 2 years?

Answers

Answer:

the answer is ieff = 2% - 3.24%

ieff = - 1.24% = -0.0124

Therefore the money left after 1 year would be:

F = 44,000 * (1 – 0.0124)

F = 43,454.4

So the amount of money lost is:

lost = 44,000 - 43,454.4

lost = $545.6
