Answer:
(2, - 3)
Step-by-step explanation:
given the 2 equations
5x + 3y = 1 → (1)
7x + 3y = 5 → (2)
multiply all terms in (1) by - 1
- 5x - 3y = - 1 → (3)
add (2) and (3) term by term to eliminate the term in y
(7x - 5x) + (3y - 3y) = (5 - 1)
2x = 4 ( divide both sides by 2 )
x = 2
Substitute x = 2 in either (1) or (2) for corresponding value of y
(2) : 14 + 3y = 5 ( subtract 14 from both sides )
3y = - 9 ( divide both sides by 3 )
y = - 3
solution is (2, - 3)
Y-4=4/3 (x-3)
standard form would be where you is singled out giving the y intercept form
solve for y
y-4=4/3 (x)-4/3 (3)
y-4=4/3 (x)-4
y=4/3 (x)-4+4
y=4/3 (x)
Answer:
Step-by-step explanation:
make 18 a positive number on the number line and 27 a negative number on the number line
The area of this figure is 30 square cm.
Explanation
The figure consists of a rectangle and right angled triangle.
length of the rectangle l=6cm
breadth of the rectangle b=4 cm
area of the rectangle=lb=6*4 =
hypotenuse of the right angled triangle=5 cm
height h=4 cm
we have to calculate the base using pythagoras theorem
area of the triangle=
are of the figure=area of the rectangle+area of the triangle=24+6=30 sq cm
