Final answer: y=0x-2, which is y=-2
Naddika [18.5K]3 years ago
4 0

Answer:

The correct option is 1.

Step-by-step explanation:

The slope intercept form of a line.

y=mx+b

The point slope form of a line is

(y-y_1)=m(x-x_1)

where, m is slope of the line.

It is given that the slope of a line is 0 and it passes through the point (4,-2). So the point slope form of a line is

y-(-2)=0(x-4)

y+2=0

Subtract 2 from both the sides.

y+2-2=0-2

y=-2

The equation of line is y=-2. Therefore the correct option is 1.

You find the x coordinates using x = -b/2a  = -6/2(-1) = 3

Substitute 3 in the equation and find y

y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3

Hezekiel runs 1000 m at a rateof 3 minutes per km. how long does he take to run 500 m​
lana66690 [7]

Step-by-step explanation:

1 km = 1000 m

(hence the term "kilo" which means 1000).

so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.

now, we can see the solution already with our eyes.

but let's do it formally :

the rate or ratio between time and distance must be the same for the same speed.

so,

3 min / 1000 m = x min / 500 m

500 m × 3 min / 1000 m = x min

1/2 × 3 min = x min

3/2 = 1.5 min = x min

so, it takes him 1.5 minutes (90 seconds) to run 500 m.

ahrayia [7]

Answer:

Step-by-step explanation:

Sum of the angles of a triangle is ALWAYS 180°.

2x+3x+5x = 180°

10x = 180°

x = 18°

2x = 36°

3x = 54°

5x = 90°

The angles are 36°, 54°, and 90°
