Solve the two-step equation. -9x + 0.4 = 4

1 answer:

3 0

Hmm ok what thw answer would be is x=-0.4
Since you subtract 0.4 from both sides end up with -9x=3.6 and then divide -9 on both sides -9x/-9 cancel and 3.6/-9 and end up with x=0.4 hope this helped

What is the slope of the graph?

Dennis_Churaev [7]

Answer:

-4

Step-by-step explanation:

Slope can be found with $\frac{y2-y1}{x2-x1}$

Pick two points on the graph that the line runs through

(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2

Insert the coordinates into the formula

$\frac{0-4}{(-1)-(-2)}$

$\frac{-4}{-1+2}$

$\frac{-4}{1}$

Therefore the slope is -4

A rectangular prism has a base length of 6 units, base

Maurinko [17]

Answer:

The lateral area rectangular prism is $88 unit^2$ .

The area of the two bases of rectangular prism together is $60 unit^2$ .

The total surface area rectangular prism is $148 unit^2$ .

Step-by-step explanation:

Height of the rectangular prism = h = 4 units

Length of the base of the rectangular prism = l = 6 units

Width of the base of rectangular prism = b = 5 units

Rectangular prism = Cuboid

Lateral surface area of cuboid = L.S.A = 2 × h × (l+b)

Lateral surface area of rectangular prism :

$L.S.A=2\times 4 units(6 units+5units)=88 units^2$

Area of the base = l × b

Area of the base of the rectangular prism = $6 unit\times 5 unit=30 unit^2$

Area of the two bases = $2\times 30 unit^2=60 unit^2$

Total surface area of cuboid = T.S.A = 2 ×(lb+bh+hl)

Lateral surface area of rectangular prism :

$T.S.A=2\times (6unit\times 5unit+5 unit\times 4unit+4 unit\times 6 unit)$

$=148 unit^2$
