system of equations 3x + 2y = 12 and 5x – 2y = 4?

Answers

Answer 1

Answer:

x = 2

y = 3

Step-by-step explanation:

add the 2 together and the y-values drop out and you are left with:

8x = 16

x = 2

3(2) + 2y = 12

2y = 6

y = 3

Write an equation for this graph. (Use / for division and * for multiplication; do not include spaces in your answer)

Answers

Answer:

The equation of the line is;

y = 4x

Step-by-step explanation:

The general equation form of a straight line is;

y = mx + b

m

is the slope and b is the y-intercept

The graph passes through the origin and that means the y -intercept is 0

To get the value of the slope, we select any point on the graph and substitute its coordinates

Let’s select point (1,4)

Substitute this;

4 = m(1) + 0

m = 4

Thus, the equation of the line is;

y = 4x

how do you translate a figure in a coordinate plane?

Answers

Answer:

Answer down below

Step-by-step explanation:

When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change. To graph a translation, perform the same change for each point. You can identify a reflection by the changes in its coordinates.

Properties of a rhombus:

All sides are congruentDiagonals are perpendicularDiagonals are angle bisectorsDiagonals bisect each other

Solution, considering the above properties

1. m∠AED = 90°, as angle between diagonals2. m∠ADE = 90° - 67° = 23° as complementary of ∠EAD3. m∠BAE = 67°, as ∠BAE ≅ ∠EAD4. AE = CE = 5, as E is midpoint of AC5. BE = DE = 12, as E is midpoint of BD

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"

Answers

Answer:

Future Value= $207,234.2

Step-by-step explanation:

Giving the following formula:

Initial value (PV)= $140,000

Appreciation rate (r)= 4% = 0.04

Number of years (n)= 10

To calculate the future value of the car after ten years, we need to use the following formula:

FV= PV*(1+i)^n

FV= 140,000*(1.04^10)

FV= $207,234.2

rewrite the equation 12x=13-x^2

Answers

Answer:

x^2+12x-13 = 0

Step-by-step explanation:

12x=13-x^2

=>12x+x^2=13-x^2+x^2

=>x^2+12x-13 = 13-13

=> x^2+12x-13 = 0

Answer:

x² + 12x - 13 = 0

Step-by-step explanation:

12x = 13 - x²

the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;

0 = 13 - x² - 12x

0 = -x² - 12x + 13

In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:

x² + 12x - 13 = 0
