Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

For

y = 8 - 3x ← in slope- intercept form

with m = - 3 and c = 8

Kanika made the error of mixing up these values

If she had expressed the equation as y = - 3x + 8 she may have got the correct values for m and c.

(a)

y = 5x + 8 → m = 5 and c = 8

(b)

y = - x + 2 → m = - 1 and c = 2

(c)

y = 3x → m = 3 and c = 0

(d)

y = 7 - x → m = - 1 and c = 7 ( think y = - x + 7 )

(e)

y = x + 6 → m = 1 and c = 6

(f)

y = 9 - 2x → m = - 2 and c = 9 ( think y = - 2x + 9 )

(g)

y = 4 + x → m = 1 and c = 4 ( think y = x + 4 )

(h)

y = - 3x - 7 → m = - 3 and c = - 7

Answer:

(a) plane NOU

Step-by-step explanation:

The points identified on plane L are {M, N, O, U}. All but point U are on the same line.

To identify the plane we need to name 3 non-collinear points. U must be one of them. The other two could by any two from the set {M, N, O}.

One possible name for plane L is plane NOU.

Maru [420]

The answer is 1.5. We can find this by arranging the data set from least to greatest, 011234, and then finding the middle number. Since the amount of spaces is even, we need to find the number in between 1 and 2. The answer is 1.5!

Please mark brainliest.

Hope this helps!

The diagram shows the sector of a circle with the centre O and radius 6cm.

Answer:

Area of the shaded region = 1.92 cm²

Step-by-step explanation:

From the picture attached,

Area of the shaded region = Area of the sector OMN - Area of the triangle OMN

Area of sector OMN = $\frac{\theta}{360}(\pi r^{2})$

Here, θ = Central angle of the sector

r = radius of the sector

Area of sector OMN = $\frac{50}{360}(\pi )(6)^2$

= 15.708 square cm

Area of ΔOMN = 2(ΔOPN)

Area of ΔOPN = $\frac{1}{2}(OP)(PN)$

Area of ΔOMN = OP × PN

In ΔOPN,

sin(25°) = $\frac{PN}{ON}$

PN = ONsin(25°)

= 6sin(25°)

= 2.536 cm²

cos(25°) = $\frac{OP}{ON}$

OP = ONcos(25°)

OP = 6cos(25°)

OP = 5.438 cm

Area of ΔOMN = 2.536 × 5.438

= 13.791 cm²

Area of the shaded region = 15.708 - 13.791 = 1.917 cm²

≈ 1.92 cm²
