How many solutions does this system have? y=5x-1 y=-3x+7

Mathematics
1 answer:
Vesnalui [34]3 years ago

Answer:

One solution

Step-by-step explanation:

We have the system

y=5x-1\\y=-3x+7

To solve the system, equate both equations and solve for the variable x.

5x-1= -3x+7\\\\5x + 3x = 7 +1\\\\8x = 8\\\\x=1

Now substitute the value of x in any of the two equations and solve for the variable y.

y=5(1)-1

y=4

Finally the system of equations has one solution

The answer is D.

350 multiplied by 6 is equal to 2100

350 * 0.5 (30 minutes) is equal to 175

2100 + 175 = 2275

ΔQTR and ΔSTP are similar triangles. The corresponding sides of similar triangles are the same length.
TR = PT
TS = QT

Input the algebraic expression to make an equation system
PT = TR
y = 2x - 1 <em>(first equation)</em>

TS = QT
6x + 13 = 5y
6x - 5y = -13  <span><em>(second equation)</em>

</span>Using subtitution method, subtitute y with 2x - 1 from first equation into the second equation, to find the value of x
6x - 5y = -13
6x - 5(2x - 1) = 13
6x - 10x + 5 = 13
-4x + 5 = 13
-4x = 13 - 5
-4x = 8
  x = 8/-4
  x = -2

Find y with subtituting x with -2 in the first equation
y = 2x - 1
y = 2(-2) - 1
y = -4 - 1
y = -5

Answer:
x = -2
y = -5

My brain just kind of exploded when reading this, please help!​

Answer:

4.8 liters

Step-by-step explanation:

o=orange juice c=cranberry juice

Punch = 4/5o + 1/6c  it means that any quantity of punch will have the same proportion of the two ingredients

now, you know that 1 liter can be written as 6/6 liters, so to get those 6/6 you multiply 1/6 by 6

for the proportion to remain valid, you must multiply by 6 also the other ingredient so (4/5)*6 = 24/5 of a liter of orange juice per liter of cranberry juice and 24/5 = 4.8 liters

Simplify.

2x + 7y + 3x - 4y

Collect all the like terms:

2x + 3x = 5x

7y - 4y = 3y

And you end up with 5x + 3y as your final answer :)

In the barn, there are horses and chickens. There are 11 heads and 32 legs altogether. How many chickens are there?
Masteriza [31]

Answer:

6 Chickens

Step-by-step explanation:

Let  H represent the number of horses and  C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:

2C  +  4 H  =  32     (Eq. 1)

Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:

C  +  H  =  11    (Eq. 2)

From Eq. 2, solve for the number of chickens:

C  +  H  =  11

C   =  11  - H    (Eq. 3)

Substituting Eq. 3 in Eq. 1, the number of horses can be determined:

2 C  +  4 H  =  32

2 ( 11  −  H )  +  4 H  =  32

22   −  2 H  +  4 H  =  32

2H  =  32  − 22

2 H  = 10

H = 5               Eq.4

Putting Eq.4 in Eq.1

2C + 4*5 =  32

2C = 32 - 20

2C = 12

C = 12/2

C = 6
