Find the point of intersection for the pair of linear equations.<br> x +y = 0.3<br> y=3x + 16.7
Nookie1986 [14]

Answer:

B

Step-by-step explanation:

You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)

X+y=0.3

y=3x+16.7

use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)

x+3x+16.7=0.3

4x+16.4=0

4x=-16.4

x=-4.1

y=0.3+4.1=4.4

PLEASE HELP I DONT UNDERSTAND!!
slega [8]

Answer:

see explanation

Step-by-step explanation:

3x and 144 are adjacent angles on a straight line and sum to 180°

3x + 144 = 180 ( subtract 144 from both sides )

3x = 36 ← value of 3x

divide both sides by 3

x = 12

and

2y - 5 and 95 are vertically opposite angles and are congruent, so

2y - 5 = 95 ← value of 2y - 5

add 5 to both sides

2y = 100 ( divide both sides by 2 )

y = 50

Then

x + y = 12 + 50 = 62
