Y=−2x+7 and y=0.5x−5.5 point of intersection

Mathematics
1 answer:
Tema [17]2 years ago
3 0

Answer:

(5, -3)

Step-by-step explanation:

Substitute -2x + 7 for y in the 2nd equation, and then solve the resulting equation for x:

-2x + 7 = 0.5x - 5.5

Combining like terms, 2.5x = 12.5, or x = 5.

Subbing 5 for x in the first equation, we get:  y = -2(5) + 7 => y = -3

The solution is (5, -3)

ANSWER

B. 10

EXPLANATION

We need to find the value of x first.

It was given that the perimeter of triangle XYZ is 24.

This means that:

XY+YZ+XZ=24

we substitute the expression in terms of x to get;

(5x - 1) + (13 - x) = 24

This implies that

5x - x = 24 - 13 + 1

4x = 12

Divide both sides by 4 to get;

x = 3

|WY|=|ZX|=13-3=10

Work out the value of angle x
Alexus [3.1K]

well, it's isosceles so use base angles theorem

the top angle is also x

90 + 2x = 180

subtract 90 from both sides

2x = 90

divide both sides by 2

x = 45 degrees
