y= x-2
this is because the y intercept is -2, and we can see that the slope is going up one over one, so m=1, and there is no need for a number in front of x

write each of the following expressions as a power of two (4x2^5)\(2^3x1/16)

P.S. the x is a multiplication sign not a variable

Answers

Answer:

Step-by-step explanation:

Rewrite as : (2^2 * 2^5) / (2^3 * 2^4)

= 2^7 / 2^(-1)

Note: Based on exponent rules you do 2 power 7 minus, minus seven. And 2 minus is a positive. So you do 2 power seven plus 2 power 1. That is 2 power 8.

= 2^8

Answer:

The lengths of AB and EF are 10 and 2 respectively

Step-by-step explanation:

The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

At the deli counter in the supermarket, Nigel paid $10 for 2 1/2 pounds of roast beef. The cost of deli meat is proportional to its weight. What is the equation for the graph of this proportional relationship?(1 point)

Answers

Step 1: set up proportion for the cost per pound of meat this is cost divided by pounds of meat

Step 2: use the solution and multiply it by x because you multiply the amount of meat (pounds) you are buying by the cost
10 = 2.5x
X represents the cost of the deli meat

If no justification for work, you shall get reported bc of spam of points. Thank you!!

Answers

Answer:

Step-by-step explanation:

Sky High $50 = 10 people so on $5 each person

Jump it up $70 fee then $2 per person

90 for 10 people at jump it up

100 for 15 people at jump it up

75 for 15 at sky high

110 for 20 people at jump it up

100 for 20 at sky high

118 for 24 people at jump it up

120 for 24 people at sky high

the minimum number of friends for it to be cheaper at jump it up is 24 friends since it would be $118 compared to $120 at sky high

the set up fee of 70 then 2 per friend compared to 50 for 10 to start then 5 each makes it come down to 24 friends in all for jump it up to be cheaper minimum anything lower sky high is cheaper
