The solution to the system of linear equations is where the two lines intersect.

Look for the point where the two lines intersect. The x-value is 2 1/2, and the y-value is -4.

The answer is C.

Answer:

C). (2 *1/2, -4)

Step-by-step explanation:

The solution to the system of linear equation is where the the x axis intercept the y axis..

So if we use Tracing method, we'll discover that where both axes meet is at

.(2 *1/2, -4)

The sum of the measures of the angles of a triangle is 180 degrees°. The smallest angle of the triangle has a measure one fourth

vivado [14]

Answer:

8°,32°,140°.

Step-by-step explanation:

Sum of measure of angles of a triangle is 180°

Let the second smallest angle be x°

Smallest angle= $\frac{1}{4}$ x

Largest angle= 5 x- 20°

A T Q

x+ $\frac{1}{4}$ x + 5x-20= 180°

$\frac{4x+x+20x}{4}$ = 180+ 20

$\frac{25x}{4}$ = 200

x= $\frac{200}{25}$ × 4

x= 32°'

Smallest angle is 32°

Hence, the smallest angle is $\frac{1}{4}$ x= $\frac{1}{4}$ ×32°= 8°

Largest angle is 5x- 20= 5×32- 20= 140°
