Answer:

Step-by-step explanation:

You want to set it equal to zero!

-x+2y+4=0

*this would be the answer IF the answer is asking you to set it equal to zero. BUT for slope intercept form this is the steps:

-x+2y=4 (subtract x and move to the other side of the equal sign):

2y=4+x

Divide both sides by 2:

y=2+1/2x

ALWAYS PUT YOUR VALUE WITH X IN FRONT OF YOUR NUMBER

y=1/2x+2

For each pair figures, find the ratio of the area of the first figure to the area of the second. 14mm 7mm

Paraphin [41]

The ratio of the area of the first figure to the area of the second figure is 4:1

<h3>Ratio of the areas of similar figures </h3>

From the question, we are to determine the ratio of the area of the first figure to the area of the second figure

The two figures are similar

From one of the theorems for similar polygons, we have that

If the scale factor of the sides of two similar polygons is m/n then the ratio of the areas is (m/n)²

Let the base length of the first figure be ,m = 14 mm

and the base length of the second figure be, n = 7 mm

∴ The ratio of their areas will be

$(\frac{14 \ mm}{7 \ mm})^{2}$

$= \frac{196 \ mm^{2} }{49\ mm^{2} }$

$=\frac{4}{1}$

= 4:1

Hence, the ratio of the area of the first figure to the area of the second figure is 4:1

A dog buried 18 bones in his backyard. On Monday, he dug up 1/2 of his bones. On Tuesday, he dug up another 1/3 of his bones. Ho

Korolek [52]

Answer:

Step-by-step explanation:

A dog buried 18 bones

On Monday he dug up 1/2 of the bones

On Tuesday he dug up 1/3 of the bones

= 1/2 × 18

= 9

= 1/3×18

= 6

Therefore the remaining bones still buried in the ground can be calculated as follows

= 9+6

= 15

= 18-15

= 3

Hence 3 bones are still buried in the ground

Step-by-step explanation:

[(24/3) + (5*2^2)] = 28

[(3 + 5) * 2^2 )]/24 = 32/24 = 4/3

[(24/3 + 5)*2^2] = 52

[(3 + 5*2^2)/24] = 23/24
