Answer 1

Answer:

So answer is C.

Hmm first I'll check the slanted line cutting 2nd quardrant..

some points on this line are (-3,0),(0,3),(2,5),(3,6),etc.

Testing (-3,0)=(x,y):

y=-3+3=0 (true)..comparable with y=x+3

Testing (2,5)=(x,y):

y=2+3=5 (true)..comparable with y=x+3

Since this line bounds the value within some limits less than or equal to x+3(see graph you can see it clearly)...so it can be represented by y<=x+3.

Similarly for next line cutting 1st and 4th quardrant,

Points: (0,-4),(1,-1),(2,2),etc..

Testing (0,-4)=(x,y):

y=3*0-4=-4(true)...comparable with y=3x-4

Testing (1,-1)=(x,y):

y=3*1-4=-1(true)...comparable with y=3x-4

This line bounds within the region y>3x-4

NOTE:

1)If the region is bounded by solid line(line without dot) then you write inequality as y<=something or y>= something.

2)If the region is bounded by dotted line(line withdot) then you write inequality as y<something or y> something.

Hope this helps!

How many solutions are there to the system of equations? 4x-5y=5 -0.08x+0.10y=0.10

Answers

Using substitution method, the system of linear equations has no solution.

What is the solution to the system of equations?

To determine the solution to the system of equations, we can use substitution method;

4x - 5y = 5 ...eq(i)

-0.08x + 0.10y = 0.10 ...eq(ii)

From equation (i)

4x - 5y = 5

let's make x the subject of formula;

4x = 5 + 5y

x = (5 + 5y) / 4 ...eq(iii)

Put eq(iii) into equ(ii)

-0.08[(5 + 5y)/4] + 0.10y = 0.10

(-2/5 - 2/5y)/4 + 0.10y = 0.10

y = no solution

Since y has no solution, this implies that the system of linear equations has no solution.

Simple..

you have:

4x-5y=5

-0.08+0.10y=0.10

Take....

4x-5y=5----> *1 -----> 4x-5y=5

-0.08+0.10y=0.10---> *50---->-4x+5y=5

Now....

4x-5y=5
-4x+5y=5

As you may be able to tell it has no solution.

Thus, your answer.

Q5: What is the measure of JH?Question 5 options:

12

300

18.75

33.33

Answers

Answer:

The answer to your question is 12

Step-by-step explanation:

Use proportion to solve this problem

Equation

$(JH)/(MQ) = (JL)/(MP)$

Substitution

$(x)/(20) = (15)/(25)$

25x = 15(20)

25x = 300

x = 300 / 25

x = 12

x = JH = 12

Answer:

the correct answer is option A. 12

The number that rode in columns was 3 2/3 times the number that rode in rows. If 2200 rode in columns, how many rode in rows?

Answers

Answer:

600

Step-by-step explanation:

Given parameters:

Number that rode in columns = $3(2)/(3)$ times the number that rode in rows.

2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

Let the number of people that rode in columns = C

Let the number of people that rode in rows = R

C = $(11)/(3)$ R

Number of people that rode in rows = 2200;

2200 = $(11)/(3)$ R

11R = 2200 x 3

R = $(2200 x 3)/(11)$

R = 200 x 3

R = 600

Number of people that rode in rows = 600
