Answer:

Step-by-step explanation:

you find slope (y1-y2)/(x1-x2) = (0-1)/(4-5) = -1/-1= 1

then you take a point (4,0)

y-0 = 1(x-4)

I hope this helps!

Answer:

y = x - 4

Step-by-step explanation:

The equation is just y = x shifted down 4 units, so it's y = x - 4. If you have to use all of the symbols, you can write "y = x * 1 - 4 + 0". Otherwise, use the one under "Answer" as it is shorter

How do i find the volume of these similar solids? round to the nearest tenth HELP

FromTheMoon [43]

Answer:

The volume of the larger solid is $592.6\ mm^3$

Step-by-step explanation:

The question is

If these solids are similar, find the volume of the larger solid

step 1

Find the scale factor

we know that

If two solids are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

x ----> the height of the larger solid in mm

y ----> the height of the smaller solid in mm

z ---> the scale factor

$z=\frac{x}{y}$

we have

$x=4\ mm\\y=3\ mm$

substitute

$z=\frac{4}{3}$ ---> scale factor

step 2

Find the volume of the larger solid

we know that

If two solids are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

x ----> the volume of the larger solid in cubic millimeters

y ----> the volume of the smaller solid in in cubic millimeters

z ---> the scale factor

$z^3=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=250\ mm^3$

substitute the values

$(\frac{4}{3})^3=\frac{x}{250}$

solve for x

$(\frac{64}{27})=\frac{x}{250}$

$x=250(\frac{64}{27})$

$x=592.6\ mm^3$

When evaluating algebraic expressions, the first thing is to

Ede4ka [16]

You have to use the order of operations when evaluating algebraic expressions. The mnemonic device is PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So the first thing is to solve what's in the parentheses.

WIL GIVE BRAINLIEST ANSWER! HELP ASAP!

Evgesh-ka [11]

Answer:

Multiply the divisor and dividend by 100.

Step-by-step explanation:

The first step is to eliminate decimal points in both divisor and dividend. Since to convert 0.15 to a whole number you multiply by 100 then it means both the divisor and dividend should be multiplied by 100. So that we shall have 4860/15=324
