Determine the intercepts of the line.

Mathematics
1 answer:
djverab [1.8K]2 years ago
5 0

y = -3x +12\\\\\text{Plug x = 0 to find  y - intercept,}\\\\y = -3(0) +12 = 12\\\\\text{So, y-intercept is (0,12).}\\\\\text{Plug y=0 to find  x - intercept,}\\\\0 = -3x +12\\\\\implies -3x = -12\\\\\implies 3x = 12\\\\\implies x = \dfrac{12}{3} = 4 \\\\\\\text{So, x - intercept is (4,0).}

Find the lateral area.<br>10 is the height.
VMariaS [17]

Answer:

The lateral surface area of a cuboid is 180 units² .

Option (c) is correct.

Step-by-step explanation:

Formula

Lateral surface area of a cuboid = 2hl + 2hb

Where h is the height , l is the length and b is the breadth.

As shown in the figure.

Length = 4 units

Breadth = 5 units

Height =  10 units

Put in the formula

Lateral surface area of a box = 2 × 10 × 4 + 2 × 10 × 5

                                                = 80 + 100

                                                = 180 units ²

Therefore the lateral area of the cuboid is 180 units² .

Option (c) is correct.

Solve the linear equation 1/2x+10=1/4x+54<br><br><br>i can never do the fraction ones.
Norma-Jean [14]
I think x = 1/176
1/2x + 10 = - 1/4x + 54
1/2x + 10 = - 1/4x + 54, x 0 
1/2x - 1/4x = 54 - 10 
2-1 over 4x = 44
1/4x = 44
1 = 176x
x = 1/176
I could be wrong.

love history [14]

Answer:

D.

x >  - 10

Step-by-step explanation:

- 5(x+3) > - 3x + 5

- 5x - 15 >  - 3x + 5

- 5x + 3x > 5 + 15

- 2x > 20

x > \frac{20}{ - 2}

x >  - 10
