Convert the following into slope-intercept form. 3x+4y=-16

Answers

Answer:

y = -3/4x -4

Step-by-step explanation:

3x+4y=-16

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

Subtract 3x from each side

3x -3x+4y=-3x-16

4y = -3x-16

Divide each side by 4

4y/4 = -3x/4 - 16/4

y = -3/4x -4

Answer:

y= -3/4x - 4

Step-by-step explanation:

3x+4y=-16

4y= -3x-16

y= -3/4x -4

Find the values of x and y that satisfy the equation –21 + 5yi = 7x – 10i.

Answers

Answer:

The values of x and y are x = -3 and y = -2

Step-by-step explanation:

In the complex numbers if a + bi = c + di, then the real parts are equal and the imaginary parts are equal

a = cb = d

Let us use this rule to solve the question

∵ -21 + 5yi = 7x - 10i

∴ The real parts are -21 and 7x

∴ The imaginary parts are 5y and -10

∵ The real parts are equal

∴ 7x = -21

→ Divide both sides by 7

∴ [tex]\frac{7x}{7}[/tex] = [tex]\frac{-21}{7}[/tex]

∴ x = -3

∵ The imaginary parts are equal

∴ 5y = -10

→ Divide both sides by 5

∴ [tex]\frac{5y}{5}[/tex] = [tex]\frac{-10}{5}[/tex]

∴ y = -2

∴ The values of x and y are x = -3 and y = -2

Answers

Slope is -2 and intercept is -3
You get the slope from the number in front of the x and the y intercept from the other number

Answer:

9-(6x+1)=3x+8 please help me with this I don’t know how to solve it.

Answers

Answer: 0

Step-by-step explanation: You isolate the variable by dividing each side by factors that don't contain the variable.

okay i have two 'true or false' questions from algebra 1:

1.) "A dotted line is ordered pairs that make the equation/inequality true. True or false?"
2.) "When you have a solid line, any point in the shaded region or on the line will make the inequality true. True or false?"

Answers

1.) False
2.) True

1.) a dotted line infers that any ordered pair that comes after the line is true. Ordered pairs that fall on the line will falsify the inequality.
2.) With solid line graphed inequalities, and ordered pair on the line OR in the shaded region makes the inequality true.

The value of Erica's approximate monthly payment is $375.70. The correct option is C .

What is the meaning of Rate of Interest  ?

Rate of Interest is the rate at which a loan is borrowed or the rate at which an investment gives return .

It is given that

Student Loan Total =  $29,158

Rate of Interest = 9.4 %

Time Period = 10 years

The monthly payment is given by

[tex]\rm \dfrac{F p(i) }{ ( 1 - ( 1 + i )^{-n})}[/tex]

Substituting the values in the equation

[tex]\rm = \dfrac{29158* (0.094/12) }{ ( 1 - ( 1 + (0.094/12) )^{-12*10})}[/tex]

= $ 375.70

Therefore,The value of Erica's approximate monthly payment is $375.70. The correct option is C.

A mixed number is a number that contains an integer with a proper fraction eg: [tex]1\frac{1}{2}[/tex]. The fraction that is given is improper and can be turned into a mixed number to simplify it.

First, we need to find how many times 15 goes into 62:

the works man family car travles 165 miles over 3 hours. Their cousins family car travles 150 miles over 2 hours. If the family reunion is 900 miles away for both familys and asuming both familys continue at the same rate who will arive first? what is the speed of each family?

Thank you so much

Answers

Answer:

see answers down below

Step-by-step explanation:

The works man family is driving at a speed of 55 miles per hour

Their cousins family drives at 75 miles and hour.  (use the miles/hours ratio like I told you in the last answer)

900 miles/75 miles traveled by their cousins each hour equals 12 hours.

If the works man family is driving at 55 miles and hour, 900 miles needed to be traveled/ 55 miles an hour equals 16.3636363636.  This is more than 12 hours, and that means that their cousins will arrive first.  Hope this helps!
