Answer:

y = 8

Step-by-step explanation:

(y - 2) × 5 = 30

(y - 2) × 5 ÷ 5 = 30 ÷ 5

y - 2 = 6

y - 2 + 2 = 6 + 2

y = 8

<u>Check</u>

(8 - 2) × 5 = 30

6 × 5 = 30

Nichior compared the slope of the function graphed to the slope of the linear function that has an x-intercept of 2/3 and a y-in
marusya05 [52]

Answer:

The slope of f(x) is 1.5

Step-by-step explanation:

step 1

Find the slope of the linear function that has an x-intercept of 2/3 and a y-intercept of -1

so

we have the points

(2/3,0) and (0,-1)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-1-0}{0-2/3}

m=\frac{-1}{-2/3}

m=\frac{3}{2}=1.5

step 2

Find the slope of the function graphed

take the points

(0,-1) and (3,6)  approximately

substitute in the formula

m=\frac{6+1}{3-0}

m=\frac{7}{3}=2.33

step 3

we know that

f(x) represents the function with the smaller slope

The smaller slope is 1.5

therefore

The slope of f(x) is 1.5

Solve 8(m - 5 ) = 48
Art [367]

Answer

1)8(m -5 ) = 48 \\ 8m - 40 = 48 \\ 8m = 48 + 40 \\ 8m = 88 \\  \frac{8m}{8}  =  \frac{88}{8}  \\ m = 11

2)x + 7 = 13 \\ x = 13 - 7 \\ x = 6

3)3h - 5 = 12 \\ 3h = 12 + 5 \\ 3h = 17 \\  \frac{3h}{3}  =  \frac{17}{3}  \\ h = 5 \frac{2}{3}

Hope this helps you.

Let me know if you have any other questions :-):-)

find the volume of cubical box . if the cost of painting of outer surface is rs 1440 at the rate rs 15 per mcube
bearhunter [10]
Surface of a cubical box=6(side²)

1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface  ⇒surface=cost of painting/rate

Data:
Rate=$15/m²
cost of painting=$1440

Surface=$1440/($15/m²)=96 m²

2)We find out the length of the side:

Surface of a cubical box=6(side²)

Data:
Surface of a cubical box=96 m2

Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m

3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³

Answer: the volume of this cubical box would be 64 m³.
