X= original $

Original $ - % of original $= total $

x - 15%x= $22.10
x- 0.15= 22.10
Combine like terms
0.85x= 22.10
Divide both sides by 0.85
x= $26 original price

Hope this helps! :)

4. What is the equation of line passing through (-2,4) and parallel to the line y<br> + 3x = 4?
aliya0001 [1]

Answer:

y=-3x-2

Step-by-step explanation:

step 1- find the slope

parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3

step 2- use the point slope form which is y-y1=m(x-x1)

and substitute in the numbers (only substitute y1,x1, and m)

m is the slope which we found to equal -3

x1 and y1 are the points that they gave us (-2,4) are (x1,y1)

x1=-2

y1=4

step 3- substitute

y-y1=m(x-x1)

y-4=-3(x-(-2))

simplifies to y-4=-3x-6

add 4 to both sides to get y=-3x-2

What is line r called and what are ∠1 and ∠2?
sergij07 [2.7K]

Answer:

The line r is the transversal and ∠1 and ∠2 are linear pairs.

Step-by-step explanation:

Angles such as matching angles, alternative angles, linear pair angles, etc. are created when a transversal intersects parallel lines.

Consequently, the parallel lines are p and q.

R is the transversal

The parallel lines p and q are divided by the transversal r.

As a result, lines 1 and 2 are linear pairs, and line r is the transversal.

Need help with this ASAP it’s due in 10 minutes
Gennadij [26K]

Answer:

Step-by-step explanation:

Formula to be used,

A = P(1+\frac{r}{n})^{nt}

Here, A = Final amount

P = Principal amount

r = rate of interest

n = Number of compounding (In a year)

t = Duration of investment (In years)

Question (5)

P = $4250

r = 0.015

n = 4

t = 3 years

A = 4250(1+\frac{0.015}{4})^{4\times 3}

A = 4250(1.00375)^{12}

A = $4445.24

Part (C)

1). P = $6000

   r = 0.03

   n = 2

   t = 10 years

  A = 6000(1+\frac{0.03}{2})^{2\times 10}

      = 6000(1.015)^{20}

      = $8081.13

2). P = $9000

    r = 0.05

    n = 2

    t = 8 years

    A = 9000(1+\frac{0.05}{2})^{2\times 8}

        = 9000(1.025)^{16}

        = $13360.55
