Answer:

y = -1/4x + 3

Step-by-step explanation:

you got to do the inverse, so like this

y = 4x > y = -1/4x

then you do take the coordinates (4,2) and put them into place like this:

y - 2 = -1/4(x - 4) > y - 2 = -1/4x +1 (four times -1/4 = 1)

then add the -2 on both sides

y = -1/4 + 3

A flagpole casts a shadow of 30 ft. A boy standing next to the flagpole casts a shaow of 9ft. What is the height of the flagpole

morpeh [17]

20 ft because the shadow would be 3/2 of the height. 9 is 3/2 of 6 so the height would be 20 bc 30 is 3/2 of 20

Un carpintero quiere cortar una plancha de triple y de 1m de largo y 60 cm de ancho, en cuadrados lo más grandes posibles. El ca

Ugo [173]

Answer: $20\ cm$

Step-by-step explanation:

The first step to solve the exercise is to make the conversion from meters to centimeters.

Since $1\ m=100\ cm$ , then the dimensions of the wood board in centimeters are:

$Lenght=100\ cm\\\\Width=60\ cm$

Now, you must find the Greatest Common Factor (GCF). The steps are:

- Descompose 100 and 60 into their prime factors:

$100=2*2*5*5=2^2*5^2\\60=2*2*3*5=2^2*3*5$

- Multiply the commons with the lowest exponents:

$GCF=2^2*5\\\\GCF=4*5\\\\GCF=20$

Therefore, the side lenght of each square must be:

$s=20\ cm$

The figure below shows two parallel lines intersected by a third line. What is the value of x

lisabon 2012 [21]

Answer:

$x = 20$

Step-by-step explanation:

The two angles given in the diagram are alternate interior angles. Alternate interior angles are congruent. Therefore:

(4x)° = (x + 60)°

Use the equation to solve for the value of x

$4x = x + 60$

Subtract x from both sides

$4x - x = x + 60 - x$

$3x = 60$

Divide both sides by 3

$\frac{3x}{3} = \frac{60}{3}$

$x = 20$

X = 59, y = 44

2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59

x - 15 = y
59 - 15 = y
44 = y
