How can i solve it formula y= mx + b

Mathematics
1 answer:
Serjik [45]2 years ago
4 0

Answer:

y = 4/3x - 4

Step-by-step explanation:

you are given b

so y = mx -4

you can look at the graph and see the slope from there. like the y-intercept and the x-intercept

(0,-4) and (3,0)

slope formula is y2-y1/x2-x1

and so you do -4-0/0-3

-4/-3.

so your slope formula would be

y = 4/3x - 4

Doug’s family buys 7 postcards while on vacation. Each postcard costs 0.25$ including tax. How can Doug use the number line to f
larisa [96]

Answer: Total cost is $1.75

Explanation:

Since we have given that

Number of postcards bought by Doug's family= 7

Cost of each postcard including tax = $0.25

Total cost is given by

7\times 0.25=\$1.75

Now, we want to show this in number line :

On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.

Each step is of length 0.25 and there are 7 jumps to reach required answer.

So, after 7 jumps we reach at 1.75 which is the required answer.

Hence total cost is $1.75

Need to find the volume. measurements in picture, please help.​
o-na [289]

Answer:

V = 288.5 yd^{3}

Step-by-step explanation:

To find the volume of a cone, use this equation:

V = \pi r^{2}\frac{h}{3}

r = radius

h = height

We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:

a^{2}+ b^{2}= c^{2}

The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:

a^{2}+5^{2}  =12.1^{2}

Now, solve:

a^{2}+25=  146.41                   Distribute the square

a^{2} =  121.41                           Subtract 25 from 146.41

\sqrt{a^{2} }=\sqrt{121.41}

a = 11.01862

So, the height is equal to 11.01862 yds.

Now, we can plug everything into the volume equation:

V = \pi (5)^{2}\frac{11.01862}{3}

Simplify (use calculator):

V = 288.5 yd^{3}

So, the volume of the cone is equal to 288.5   yd^{3}
