Answer:
I. C
II. A, D
III. B
Lines that coincide have infinite solutions, and parallel lines have no solutions.
Step-by-step explanation:
3. To solve this equation, look at the slopes of the equation. The equations are in y=mx+b form. m is equal to the slope.
Equations with different slopes will have one solution, meaning that the lines will intersect once.
Equations with the same slope will either have no solutions or infinite solutions. <u>If the equations are the exact same</u>, it will have infinite solutions, meaning that the line "intersects" itself in infinite places since its basically one line right on top of another. <u>If the equations have different y-intercepts</u>, it will have no solutions because the lines are going at the same angle, are parallel and will never intersect.
This means that A and D have one solution, B has infinite solutions, and C has no solutions.
4. Lines that coincide have infinite solutions, and parallel lines have no solutions.
Step-by-step explanation:
so, she spent 25-16.39 = $8.61 on the ribbon.
1 yard of the ribbon costs $0.21.
how many yards did she buy with that amount of money ?
well, as many times as 0.21 fits into 8.61 :
8.61 / 0.21 = 41
so, she bought 41 yards of ribbon.
Answer:
I think it is C) 480
Step-by-step explanation:
320÷2=160
160×3=480

Well what you do is the square root of 7 Is 49 so if you done 49 divided by 7 it would equal 7 if you squared a number you would times it by itself the square root is the opposite
First we would need the sector formula which is: 丌r^2× angle/360
To find the radius,we would have to divide the diameter by two,which is:
l8÷2=4 units
We would also need to find the total valuenof angles of pink sectors:
41+44+47=132°
As it's not mentioned,let's take pi as 3.14.
In this case,it would be:
(3.14)(4)^2(132°/360°)
=16(3.14)(11/36)
=18.4213..
≈18.4 sq. units
Thus the answer us D.18.4 units.
Hope it helps!
