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.
The sum of 2 times a number and 8 is 7
Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
2x + 8 = 7
x = -1/2
Step-by-step explanation:
"a number" can be signified by a variable.
So 2 times a number would give you 2x
And 8 would mean to add 8.
Is 7 means the end result is 7.
So 2x + 8 = 7
x = -1/2
x + 15y = 45 / x + 10y = 30 solve for x and y
Answer:
25y = 45/1x = 30
Answer:
x=10; y=2
10+15(2)=40
10+10(2)=30
so this is correct
Step-by-step explanation:
Change each fraction or mixed number to a percent.
a.2/5
b.7/20
C. 1 11/16
d. 14 1/4
Answer:
a=40%, b=35%, c=168.75, d=1425
Step-by-step explanation:
a : 2/5=4/10*100=40
b:7/20=35/100*100=35
c: 1 11/16=1.6875*100=168.75
d: 14 1/4=14.25*100=1425

What is the slope-intercept equation for the line below?
A) y = 5/4x - 4
B) y = 4/5x - 4
C) y = -4/5x - 4
D) y = -5/4x - 4
Answer:
A) y = 5/4x - 4Step-by-step explanation:
Slope-intercept formula
y = mx + b, where m = slope, b = y-interceptSlope formula
m = (y2 - y1)/(x2 - x1)Given points (on the graph)
(0, -4) and (4, 1)Slope is:
m = (1 - (-4))/(4 - 0) = 5/4y-intercept is
-4 as per the first pointSo the line is:
y = 5/4x - 4Correct answer option is: A) y = 5/4x - 4

Z is the circumcenter. What is VZ?
Answer:
VZ is 24
Step-by-step explanation:
when we talk of the circumcenter, we mean a point in the triangle that has a uniform distance from each of the vertices of the triangle
What we mean by the circumcenter is that the length between this point and any of the vertices is the same distance
ZU is a distance between the circumcenter and the vertice
What we want to calculate top is same.
So therefore, the two are equal and we have the length of what we want to
calculate as 24

A bus travels at a speed of 40 miles per hour and reaches Hogville in 40 minutes. If a cab takes 35 minutes to reach the same spot, determine the speed at which it traveled.
Answer:
45.7miles per hour
Step-by-step explanation:
40mins = 2/3 hour
the bus travelled (2/3 x 40) miles = 80/3 miles
the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)

Step-by-step explanation:
First we need to identify the cost of each hotdog for each brand. I'll go by in order.
Ball Park:
We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.
"Price/Hotdogs per package"
In order
6.95/8=0.86875 or 0.87
8.20/10=0.82
7.35/8=0.91875 or 0.92
17.50/24=0.7291666 or 0.73
Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.
