Given line: y =3x - 7

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

To find m you must take the slope of the line given, which would be 3, and take its opposite reciprocal (switch its sign to negative/positive if it was originally positive/negative and flip the numerator and denominator)

the opposite of 3 is -3 and the reciprocal of -3 is \frac{-1}{3}

This means that the slope of a line perpendicular to y = 3x - 7 is \frac{-1}{3}

This is the current formula you found:

y=\frac{-1}{3} x + b

To find the y-intercept (b) in the point that this line goes through (2, -1) into the x and y of the equation and solve for b

-1 = \frac{-1}{3}(2) + b

-1 = \frac{-2}{3} + b

\frac{-1}{3} = b

That means that the equation perpendicular to y = 3x - 7 is...

y = \frac{-1}{3} x - \frac{1}{3}

Hope this helped!

Carla is age 32. how many quarters of coverage does she need to be fully insured
never [62]
According to my research, And I would take this with a grain of salt since I am not a insurance rep . You can earn up to four quarters of coverage each year. In order to be fully insured for Social Security Disability purposes, you must have earned at least one quarter of coverage per year for each year since you turned 21 years old. A minimum of six quarters of coverage is needed to be fully insured at any age so maybe Six quarters, at least according to SSD .
Hope I helped or shed some light !.

What does equivalent fracations means?​
Diano4ka-milaya [45]

Answer:

Equivalent fractions are fractions that have the same value or amount even if they seem different. They are a type of fraction that are equivalent in nature.

Step-by-step explanation:

Equivalent means being equal in value, function, amount or meaning. Even if they seem different they are the same in their own way (and I'm talking about fractions now)

Describe how to evaluate the expression 3^2 + (21 - 9) X 6÷2. Can someone help me out, please? I'm having trouble, and my teache
mylen [45]

Answer:

3^2+\left(21-9\right)\times \:6\div \:2=45

Step-by-step explanation:

Given the expression

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

Follow the PEMDAS order of operations

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

calculate within parentheses  \:(21-9)=12

=3^2+12\times \:6\div \:2

calculate exponents  3^2=9

=9+12\times \:6\div \:2

Multiply and divide (left to right)

=9+36

Add and subtract (left to right)  12\times \:\:6\div \:\:2=36

=45

Thus,

3^2+\left(21-9\right)\times \:6\div \:2=45

Please help I think I picked the wrong answer !!
insens350 [35]

Answer:

one solution

Step-by-step explanation:

it has one solution because the slopes of the two equations(1x & 2x) are different, which means the lines of the two equations are not parallel, they have an intersection point(also means one solution).
