Answer:

3.) y-int = 0

4.) y-int = -1

5.) slope = 2

y-int = 4

6.) slope = -1

y-int = -6

7.) slope = 5

y-int = 8

8.) slope = 7

y-int = 1/2

Step-by-step explanation:

basically, you want to get each of your functions in terms of (y = mx + b)

for each of these:

m will be your slope

b will be your y-intercept

5) the slope is -2, y-intercept is 1. 6) slope is 1, y-intercept is 1. 7) slope is -5, y-intercept is 8. That’s all I could find :( sorry. Hope that helped. I’m also not that good at math

An electric bulb is sold in a box measuring 5 cm by 4 cm by 4 cm. If the shopkeeper receives them in a carton measuring 50 cm by

katen-ka-za [31]

Answer:

250

Step-by-step explanation:

Bulb box and carton both are of cuboidal shape.

For bulb box the dimensions are:

l = 5 cm, w = 4 cm, h = 4 cm

$V_{Bulb\: box} =lwh$

$\implies V_{Bulb\: box} =5(4)(4)$

$\implies V_{Bulb\: box} =80\: cm^3$

For Carton the dimensions are:

l = 50 cm, w = 20 cm, h = 20 cm

$V_{Carton} =lwh$

$\implies V_{Carton} =50(20)(20)$

$\implies V_{Bulb\: box} =20,000\: cm^3$

To find the number of bulbs packed in the carton, divide the $V_{Carton}$ by $V_{Bulb\: box}$

$Number \:of \:bulbs =\frac{V_{Carton}}{V_{Bulb\: box}}$

$\implies Number \:of \:bulbs =\frac{20,000}{80}$

$\implies Number \:of \:bulbs = 250$

So, 250 bulbs will be packed in one carton.

Answer:

a. 0.81

b. v = 28000(0.81^n)

c. 2757.36

Step-by-step explanation:

a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...

1 -0.19 = 0.81

b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:

value = (original value) × (growth factor)^n

v = 28000(0.81^n)

c. For n=11, this is ...

v = 28000(0.81^11) ≈ 2757.36

The value of the truck after 11 years is about $2757.

What is the equation that has a slope of -4 and passes through the coordinates (-4,14)

Agata [3.3K]

Answer:

y=-4x-2

Step-by-step explanation:

y-y1=m(x-x1)

y-14=-4(x-(-4))

y-14=-4(x+4)

y=-4x-16+14

y=-4x-2

What is the measure of angle 4?

Ymorist [56]

Answer: C) 108 degrees

------------------------------------------------------

Explanation:

Angle 4 is an exterior angle which corresponds to the remote interior angles of 33 degrees and 75 degrees. Through the remote interior angle theorem, we can add the remote interior angles to get the exterior angle

So we simply add 33 and 75 to get 33+75 = 108

If you chose not to use this theorem, then you can find angle three by using the fact that all three angles of the triangle must add to 180 degrees. So,

33+75+(angle 3) = 180
108+(angle 3) = 180
108+(angle 3) - 108 = 180 - 108
angle 3 = 72 degrees

Then use the fact that angle 3 and angle 4 are supplementary

(angle 3) + (angle 4) = 180
72 + (angle 4) = 180
72 + (angle 4) - 72 = 180 - 72
angle 4 = 108 degrees

either way, we get the same answer
