6x+5y=19 2x+3y=5 Elimination Method to Solve Linear Equations

Mathematics
1 answer:
Anarel [89]3 years ago
7 0

Answer:

x = 4 and y = -1

Step-by-step explanation:

Given that,

6x+5y=19  ... (1)

2x+3y=5 ...(2)

We need to solve the above equations.

Multiply equation (2) by 3.

6x+9y=15 ...(3)

Subtract equation (1) and (3).

6x+5y-(6x+9y)=19-15

6x+5y-6x-9y = 4

-4y = 4

y = -1

Put the value of y in equation (2).

2x+3(-1)=5

2x-3=5

2x=8

x=4

So, the solution of the above equations are x = 4 and y = -1.

Emily designed a robot that could climb down steps. She drew a graph to show the results from a test of her new robot. The graph
kifflom [539]

So youre a given two points. The points (0,15) and (150,0). First solve the slope of the graph

M = (y1 – y2) / (x1 – x2)

M= (15 – 0) / ( 0 – 150)

M = - 0.1

Using point (15,0)

15 = -0.1(0) + b

15 = b

So y = mx + b

Y = -0.1x + 15

$800 is invested at a rate of 7%. What will be the total amount of the investment after 3 1/2 years?
torisob [31]

Answer:

A = $996.00

Step-by-step explanation:

(I = A - P = $196.00)

Equation:

A = P(1 + rt)

Where:

A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

r = Rate of Interest per year in decimal; r = R/100

R = Rate of Interest per year as a percent; R = r * 100

t = Time Period involved in months or years

From the base formula, A = P(1 + rt) derived from A = P + I and I = Prt so A = P + I = P + Prt = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year.

Solving our equation:

A = 800(1 + (0.07 × 3.5)) = 996

A = $996.00

The total amount accrued, principal plus interest, from simple interest on a principal of $800.00 at a rate of 7% per year for 3.5 years is $996.00.
