What is the graph of the function rule? y = 3x - 2 Choose from the pictures

bulgar [2K]

we have

$y=3x-2$

we know that

this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes

1) Find the y-intercept

the y-intercept is when the value of x is equal to zero

For $x=0$

find the value of y

$y=3*0-2$

$y=-2$

2) Find the x-intercept

the x-intercept is when the value of y is equal to zero

For $y=0$

find the value of x

$0=3x-2$

$x=(2/3)$

therefore

the answer is the option B ( see the attached figure)

5 Michiko has a metal container in the shape of a cuboid. The container is 2.4 m long, 1.2 m wide and 0.6 m high. Michiko plans

konstantin123 [22]

Answer:

a) Michiko needs to buy 18 tins of paint.

b) cost of paint would be $152.82

Step-by-step explanation:

Surface area of cuboid = 2lw + 2lh + 2hw

Length (l) = 2.4 m

Width (w) = 1.2 m

Height (h) = 0.6 m

SF = 2(2.4 × 1.2) + 2(2.4 × 0.6) + 2(0.6 × 1.2)

= 5.76 + 2.88 + 1.44

= 10.08 meter²

Paint coverage is 4.5 meter² per liter.

Total paint used in one coat =

= 2.24 liters

Paint used in double coats = 2.24 × 2 = 4.48 liters

a) Size of one tin paint = 250 ml

1 liters = 1000 ml

4.48 liters = 4.48 × 1000 = 4480 ml

Number of tins needed by Michiko =

= 17.92 ≈ 18 tins

b) Cost of one tin of metal paint = $8.49

∴ cost of 18 tins of paint = $152.82

a) Michiko needs to buy 18 tins of paint.

b) cost of paint would be $152.82
