Y = 3 - x 5x + 3y = -1

Mathematics
1 answer:
oksano4ka [1.4K]3 years ago
6 0

Answer:

y = 8, x= -5

Step-by-step explanation:

y = 3 - x

5x + 3y = -1

By putting the value of Y in second equation

5x + 3 (3-x) = -1

5x + 9 - 3x = -1

2x = -1 -9

2x = -10

x = -10//2

x= -5

By putting the value of x in equation 1

y = 3 - (-5)

y = 3 + 5

y = 8

Solve each system by substitution<br><br> 2x - 3y = -1<br> X + 4y = -6
lord [1]

Answer:

(- 2, - 1 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 1 → (1)

x + 4y = - 6 → (2)

Rearrange (2) expressing x in terms of y by subtracting 4y from both sides

x = - 6 - 4y → (3)

Substitute x = - 6 - 4y into (1)

2(- 6 - 4y) - 3y = - 1 ← distribute and simplify left side

- 12 - 8y - 3y = - 1

- 12 - 11y = - 1 ( add 12 to both sides )

- 11y = 11 ( divide both sides by - 11 )

y = - 1

Substitute y = - 1 into (3) for corresponding value of x

x = - 6 - 4(- 1) = - 6 + 4 = - 2

Solution is (- 2, - 1 )

Slope = y2-y1 / x2 - x1

= -8-2 / -10-5
= -10 / -15
= 2/3

A 50 centimeter piece of wire is bent into a circle. What is the area of this circle?
Korvikt [17]

Answer:

198.95 cm²

Step-by-step explanation:

Circumference = 50cm

C = πD

D = C/π

r = D/2

r = 50/π/2

r= 7.957747…..cm

Area = π r²

A = π x 7.957747….²

A = 198.95 cm² (2dp)
