2 × 2 = 4 ;
x^9 × x^4 = x^13 ;
y^7 = y^7 ;
z × z^3 = z^4 ;
(2x^9y^7z)(2x^4z^3) =4x^13y^7z^4 ;

A line passes through the point (–6, –2), and its y-intercept is (0, 1). What is the equation of the line that is perpendicular

Mama L [17]

The slope of first line is m 1= ( 1 - 0 ) / ( - 2 - ( - 6 ) );
m = 1 / 4 ;
Because the second line is perpendicular to the first line, m2 * m1 = - 1 ;
m2 * ( 1 / 4 ) = -1;
m2 = - 4 ;
The equation of the second line is : y - 3 = ( - 4 )( x - 2 );
y - 3 = -4x + 8 ;
y = -4x + 11.

What percent of 3000 is 18??

77julia77 [94]

To solve this problem you have to set up a proportion. To form one side of the proportion you use "is over of" meaning what number represented by is, in this case 18, is placed over the number represented by of, 3000. $\frac{18}{3000}$ Since you are finding the percent of something, youre x value is placed above "100" because percent values are most commonly out of 100%. $\frac{x}{100}$
So now your proportion will look like $\frac{18}{3000}$ $\frac{x}{100}$ To solve the proportion you cross multiply and divide. So you multiply 100 and 18 since they are crossed from each other, then divide 1800 by 3000. The answer is .6. 18 is .6% of 3000.

If you just write whatever just for the points i will report you.

Hoochie [10]

Answer:

Below!

Step-by-step explanation:

The best way to answer this question is to read the statement carefully.

=> Five less than twice a number = 2x - 5
=> Five times the sum of two numbers = 5(x + y)
=> The difference of 5 and a number, squared = (5 - x)²

Hoped this helped.

Maddox McDonald A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move

harina [27]

Answer: 2/3 feet per minute

Step-by-step explanation:

From the question, we are informed that a caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes.

The rate at which the caterpillar move in feet per minute will be:

= 4 2/3 ÷ 7

= 14/3 ÷ 7

= 14/3 × 1/7

= 14/21

= 2/3 feet per minute
