A line passes through the point (3,9) and has a slope of 4

expeople1 [14]

Point-slope form is y - y1 = m(x - x1). We just need to plug in our stuff. This gives us y - 9 = 4(x - 3). I am not sure if you need to simplify, but if you do, y - 9 = 4x - 12.

HELP ME PLEASE!!!!!!

gladu [14]

Answer:

6x²y²

Step-by-step explanation:

6: 1 2 3 6

18: 1 2 3 6 9 18

36: 1 2 3 4 6 9 12 18 36

the common factor for 6 18 and 36 are

1 2 3 6

x² = x × x

y³ = y × y × y

x³ = x × x × x

y³ = y × y × y

x³ = x × x × x

y² = y × y

the common factor are for x and y are

x² y²

Multiply the GCF of the numerical part 6 and the GCF of the variable part x² y² to get 6x² y²

Can anyone solve this for me?? I will give brainliest and 5 stars and thanks

Tcecarenko [31]

Answer:

3 cm

Step-by-step explanation:

When we enlarge or shrink an object, we perform a dilation. A dilation preserves the relationship between sides and the exact angle measure. This means the original and the enlargement are proportional and any missing lengths can be found through a proportion.

A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare height over length of the original rectangle to an equal ratio of height to length of the enlargement. Since we do not know height of the enlargement, we will use a variable to write:

$\frac{2}{9} =\frac{h}{13.5}$

I can now cross-multiply by multiplying numerator and denominator from each ratio.

$9h=2(23.5)\\19h=27$

I now solve for h by dividing by 9.

$\frac{9h}{9} =\frac{27}{9} \\h= 3$

The new height is 3 cm.
