Answer:

$50,290

Step-by-step explanation:

I was earning $47,000 per year until she received a 7% raise at the start of 2019.

Step 1

We find how much 7% raise is

Hence,

7 % of $47,000

= 7/100 × $47,000

= $3290

What will her new salary be?

Her new salary is calculated as:

Last year's salary + 7% raise

= $47,000 + $3290

= $50,290

Her new salary is $50,290

Find parametric equations for the line parallel to r = (6,-8) and passing through P (9, -1)
Oduvanchick [21]

Answer:

x = \frac{12-t}{4} and y = \frac{t - 3}{3}

Step-by-step explanation:

The slope of the line is:

m = \frac{-8-0}{6-0}

m = -\frac{4}{3}

The slope-intercept formula of the line is:

y + 1 = -\frac{4}{3}\cdot (x - 9)

y + 1 = -\frac{4}{3}\cdot x +12

A possible choice is:

3\cdot y + 3 = -4 \cdot x + 12

t = 3\cdot y + 3 = -4\cdot x + 12

3\cdot y = t - 3

y = \frac{t - 3}{3}

-4\cdot x = t - 12

x = \frac{12-t}{4}

The parametric equation for the line parallel to r = (6,-8) and passing through P (9, -1) is:

x = \frac{12-t}{4} and y = \frac{t - 3}{3}

A 99 ft length of wire is to be cut into 2 pieces, so that the longer piece is eight feet longer than six times the shorter piec
Serhud [2]

here's the solution,

let the length of shorter peice = x

then the lenght of longer peice = 6x + 8

now, we know that the sum of length of peices measures 99 feet,

So,

=》x + 6x + 8 = 99

=》7x = 91

=》x = 13

shorter piece length = 13 feet

longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
