Systems By Graphing - Solve All Correctly For a Thanks, 5-Stars, And A Brianliest!

Mathematics
1 answer:
BartSMP [9]3 years ago
4 0

Answer:

Step-by-step explanation:

Amari= Graph C and Solution is (-6,-2)

Bella= Graph A and Solution is (3,4)

Carl= Graph B and Solution is (0,-3)

0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.

No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.

1st graph: y=2x-1 and y=7 solution #1= (4,7)

2nd graph: y=-2x-3 and y=1/2x solution #2= (-2,1)

3rd graph: y=x and y= -1/5+6 solution #3= (5,5)

I had this exact same assignment a few months ago, my teacher didn't use the 2nd slide but I had the 1st and 3rd slide so this should help!

There are many cylinders for which the height and radius are the same value. Let
VashaNatasha [74]

Answer:

Relation between V and c is represented as:

V = \pi c^{3}

When c is halved, V becomes \frac{1}{8} of its initial value.

Step-by-step explanation:

Height of cylinder = Radius of cylinder = c

Volume of cylinder = V

As per formula:

V = \pi r^{2} h

Where r is the radius of cylinder and

h is the height of cylinder

Putting r = h =c

V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)

The values of c is halved:

Using equation (1), New volume:

V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}

By equation (1), putting \pi \times c^{3}  = V

V' = \dfrac{1}{8} \times V

So, when c is halved, V becomes \frac{1}{8} of its initial value.

Judy uses 9.7 pints of blue paint and white paint to paint her bedroom walls.3/5
Sindrei [870]

Answer:

3.88 Pints

Step-by-step explanation:

First we need to find the amount of blue paint that was used. We can do that by multiplying 9.7 by 0.60 since that is 3/5 in decimal form

9.7*0.60=5.82

Now we know how much blue paint was used, now we just need to find how much white paint was used. We can do that by subtracting our amount of blue paint from the total amount of paint used

9.7-5.82=3.88

thus, 3.88 is the amount of white paint used

To which subset of real numbers does the number 1/5 belong?
nasty-shy [4]

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we know that irrational numbers are those real number which cannot be written in \frac{p}{q} form.

Rational numbers are those real numbers which can be written in \frac{p}{q} form.

Inverse property of multiplication is that property in which we write a number in reciprocal form .

Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.

Hence, \frac{1}{5} belongs to rational numbers sets and inverse property of multiplication sets.

Therefore, Option 'B' and 'C' are correct.
