Answer: The answers is (A) m=-2,~~c=2.  and  (B)  m=-\dfrac{1}{2},~~c=1.

Step-by-step explanation: We are to select the slope and y-intercept of the linear function that is graphed to the left.

We know that the equation of a straight line in slope-intercept form is given by

y=mx+c,

where 'm' is the slope and 'c' is the y-intercept of the line.

Also, a straight line with a positive slope (m>0) rises from left to right whereas a line with a negative slope (m < 0) falls from right to left.

Option (A) is

m=-2,~~c=2.

Since 'm' is negative, so the function is graphed to the left.

Option (B) is

m=-\dfrac{1}{2},~~c=1.

Since 'm' is negative, so the function is graphed to the left.

Option (C) is

m=\dfrac{1}{2},~~c=2.

Since 'm' is positive, so the function is graphed to the right.

Option (D) is

m=2,~~c=1.

Since 'm' is positive, so the function is graphed to the right.

Thus, (A) and (B) are the correct options.

Sorry, I got a little confused with your question, but this will definitely help (I hope)
Y=mx+b
m=slope and b=y-intercept
This is just in case: y=range and x=domain(you don’t really need these though)...Best of luck to you:)

What is the significance of the point of intersection of a pair of simultaneous equations
Alex777 [14]

Answer:

The point of intersection gives the solution set(s) of the associated system.

Step-by-step explanation:

If we have a pair of simultaneous equations in 2 variables in x and y, then the point of intersection is the ordered pair (x,y).

This could be a unique intersection, only one point or infinitely many intersection.

This gives us the solution of the simultaneous equations.

Therefore the significance of the point of intersection of a pair of simultaneous equations is that, it gives us the solution set(s) of the associated system.

Item C sold for 5$ and item D sold for 7 you sold a combined total of 60 of item c and D and you made 400$ how many of each item
Aneli [31]

Answer:

50 of D and 10 of C

Step-by-step explanation:

First of all, put this data into 2 equations.

You sold 60 items, so C+D=60

C is $5 so we can represent it by 5C

D is $7 so we can represent it by 7D

You made $400 total from C and D, so 5C+7D=400

We can use simultaneous equations to solve this.

To eliminate one of these variables, we'll multiply the first one by 5 to make it 5C like the other.

5(C+D=60)     (make sure you multiply both sides.)

so 5C+5D=300

5C+7D=400

Now we solve it:

5C-5C+7D-5D=400-300

7D-5D=100

2D=100

D=50

Now we can substitute this with one of the equations to find C

C+50=60

C=60-50

C=10

so, (10x5)+(50x7)=400

Pls help I beg of you.
Mandarinka [93]
The semicircle is 25pi or 78.54

The rectangle is 120 (12*10)

The triangle is 24 (.5*12*4)

So the total is 222.54 (78.54+120+24)
