Answer:

The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.

Answer:

-5

Step-by-step explanation:

do the exponets first. -6 squared is positive 36 because negative times a negative is a positive.

next you multiply 4 and 7 and get 28

you have 28-36+2 and that equals -5

Given:

$10x>8(3x-2)-12$

To find:

The values of x.

Solution:

We have,

$10x>8(3x-2)-12$

$10x>8(3x)+8(-2)-12$ (Distributive property)

$10x>24x-16-12$

$10x>24x-28$ (Combining like terms)

Add 28 on both sides.

$10x+28>24x$

Subtract 10x from both sides.

$28>24x-10x$

$28>14x$

Divide both sides by 14.

$\dfrac{28}{14}>x$

$2>x$

Therefore, the values of x are all real numbers less than 2, i.e., x<2 .

The price of an item was reduced by 10% and then by 20%. Is that the same as reducing the price by 30%? If not, then what percen

Natasha2012 [34]

Answer:

28%

Step-by-step explanation:

Hello,

When the item is reduced by 10%, this is like we multiply this price by 1-0.10=0.90

When the item is reduced by 20%, this is like we multiply this price by 1-0.20=0.80

When the item is reduced by 10% and then by 20%, this is like we multiply this price by 0.90*0.80=0.72

so this is equivalent that the item is reduced by 28% (as 1-0.28=0.72)

hope this helps

Find the length of arc AB for each circle.

Eddi Din [679]

Answer:

see explanation

Step-by-step explanation:

The length of the arc is calculated as

AB = circumference of circle × fraction of circle

(11)

AB = 2πr × $\frac{90}{360}$

= 2π × 7 × $\frac{9}{36}$

= 14π × $\frac{1}{4}$

= $\frac{7}{2}$ π in

(12)

AB = 2πr × $\frac{135}{360}$ ( r = 20 ÷ 2 = 10 )

= 2π × 10 × $\frac{3}{8}$

= 20π × $\frac{3}{8}$

= $\frac{60}{8}$ π

= $\frac{15}{2}$ π cm
