Less than 4

add 5 to both sides and u get the equation 14x<-1 then divide both sides by 14 to get x alone. that leaves you with x< -1/14 wich is then less than 4

which expression can be used to find the surface area of the following square pyramid

Answers

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

The answer is a 36 + 15 + 15+ 15 +15

Does each equation represent a proportional relationship? Choose Yes or No.

y = 7x – 3 yes or no

y = 150x yes or no

Answers

Answer:

y=150x is proportional, but y=7x-3 is not.

Step-by-step explanation:

A proportional relationship is of the form where k is a constant. It is not a proportional relationship as it does not take the form y = kx. It is a proportional relationship, so we get k = 150.

P to Q: greater than 1P to R: greater than 1Q to S: less than 1Q to R: greater than 1S to P: equal to 1R to P: less than 1P to S: equal to 1

========================================================

Explanation:

We have these three rules for scale factors

scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identical

With those rules in mind, we have enlargements for these transformations.

P to QP to RQ to R

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

Q to SR to P

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

P to SS to P

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Molly has 1 1/2 cups of sugar. She used 3/4 cup of sugar. She wants to model a subtraction problem on a number line to find how much sugar she has left. Molly’s first step is shown below.

What should Molly do next, and how much sugar does she have left?
A. Move 1 1/2 units to the right. She has 1 3/4 cups of sugar left.
B. Move 3/4 unit to the left. She has 3/4 cup of sugar left.
C. Move 1 1/2 units to the left. She has 3/4 cup of sugar left.
D. Move 3/4 unit to the right. She has 2 1/4 cups of sugar left.

Answers

Answer:

it's B because 1 1/2 not simplified is 3/2, and 3/2 not simplified is 6/4. Since she wants to use 3/4 of sugar, then you need to do 6/4-3/4 which equals 3/4, the amount of sugar Molly had left.

She should move 3/4 units to the left of the 1 1/2.

y = -2x + 3

The Y intercept is positive 3

it goes down by 2 each square

Answer is y= -2x + 3

Explanation

Slope intercept form is y= mx + b

From the graph we see the y intercept is 3, it is the y axis where the line crosses

We can find slope by finding the change in rise (y) over the change in run (x)
Here we have -4 down and 2 to the right so -4/2 = -2 slope

Fill in these values

y = -2x + 3 is your answer
