Does the system have a no solution or infinitely many solutions
Y=2/3x+2-2x+3y=6
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3
pls give brainliest
Answer:
There are infinitely many solutions.
Step-by-step explanation:
There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.
Showing that both equations are equal: y=2/3x+2 -2x+3y=6
y=2/3x+2 Multiply by 3 on both sides
3y=2x+6 Rearrange (-2x on both sides)
3y-2x=6 More rearrangement
-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.

Write a brief summary about similar figures
Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.
Answer:
*You could just look it up.
Here's what I found on google:
Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
So basically, similar figures are 2 figures that are the same shape.
They don't have to be the same size.

A daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month. Her goal is to have a larger staff, including an equal number of assistant caregivers and senior caregivers. How long will that take? How many of each type will there be?
After _____months, there will be_______ of each type of caregiver
After 3 months, there will be 12 of each type of caregiver
How to illustrate the equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Since the daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month.
This will be:
9 + m = 6 + 2m
where m= number of months
Collect the like terms
2m - m = 9 - 6
m = 3
The number of caregiver will be:
9 + m
9 + 3
= 12

Find the difference
A camera store developed 2100 rolls of film in one month. Customers wanted double prints from 1500 of these rolls. What is the ratio of rolls with double prints to rolls developed?
2:7
2:5
5:7
7:5
Answer:
the answer is 5:7
Step-by-step explanation:
as a fraction, the ratio looks like this:
1500/2100
where 1500 is the number of rolls with double prints and 2100 is the amount of rolls developed.
if you simplify the fraction, you get 5/7.
5/7 is 5:7 written as a ratio in this problem.

Find the value of x. Show steps
Answer:
the answer is 2 or yellow
Step-by-step explanation:
the triangle is equal so that means that x must multiply with to and be equal to four so two time two equals four
Answer:
x=2
Step-by-step explanation:
This is a triangle and we have to find x. I will be assuming you know the basics of trig.
This is easily identifiable as congruent triangle since the rule ASA (or you can use SAS) comes into play with the shared angle LNP and MNP, the same right angles, and congruent side lengths that are the measures of length c of the triangle (the hypotenuse). we know these are congruent triangles so it is easy to find x.
MP is 4 units.
find LP.
they are congruent triangles, so MP=LP.
MP=4
LP=2x
MP=LP
4=2x
x=2
