Step-by-step explanation:

If you simplify the equations and collect terms, the following can be used to identify the number of solutions:

  a) coefficients of x are different -- one solution

  b) coefficients of x are the same and constants are different -- no solutions

  c) left side the same as right side -- infinite solutions

1. different x coefficients -- one solution

2. different constants -- no solutions

3. different x coefficients -- one solution

4. 12x +7 = 12x +7 -- infinite solutions

5. different constants -- no solutions

6. -2x -3 = -2x -3 -- infinite solutions

Answer: 160 pieces

Step-by-step explanation:

1. Convert each mixed number into an improper fraction

4 4/5 = 24/5

2. Convert to the least common denominator. In this case, the least common denominator would be 10. Since the denominator in 24/5 is 5, multiply this fraction by 2/2 to get the denominator to equal 10.

24/5 * 2/2 = 48/10

3. Divide 48/10 by 3/10, using the keep, change, flip method

48/10 * 10/3

Multiply the numerators and denominators together, respectively.

480/3

4. Simplify

480/3 = 160

There are 160 pieces.

Answer:

8/5 m.

Step-by-step explanation:

Step-by-step explanation:

ANSWER:

y=8/5x±R (Read explanation)

EXPLANATION:

Letting you know, you did not attach a picture. Thus, I'm guessing. Parallel lines mean that the slope will be the same, but the y-intercept is not. The slope here is 8/5x. That may stay the same, so here's the equation that we currently have:

y=8/5x (This can be the answer)

However, we must change the y-intercept which is -1 currently. You may change it to any real number. For example, 1, 0, -100, 10000, 999, etc. would work. So, the answer would be:

y=8/5x±R (R as All Real Numbers)

Answer:

24.59 m/s

Step-by-step explanation:

Average speed(m/s) = distance travelled(m) / time taken(s)

Distance = 220 miles

220 miles = 354,056 meters

Time taken = 4 hours

4 hours = 14,400 seconds

Average speed = distance travelled / time taken

= 354,056 / 14,400

= 24.59 meter/seconds

= 24.59 m/s

Answer:

24q + 56

Step-by-step explanation:

because you have to divide 13 divide by 1 and eat equals 13 then if you spin it the posibility might be 13

Answer:

7/13

Step-by-step explanation:

Given;

A spinner has 13 equal sections.

Find;

The probability of landing on an odd number.

1. Information that one needs to know

To calculate the probability, one needs to have the number of favorable outcomes over the total number of outcomes.

2. Solving the problem

The favorable outcomes are the odd numbers, hence one needs to find the number of odd numbers between 1 and 13. There are 7 odd numbers between 1 and 13. The total number of outcomes is 13, hence the probability of landing on an odd number is 7/13.

Given:

f(1) = 1 and f(-3) = 17

To find:

The lines function f.

Solution:

If f(a) = b, it means the function f passes through (a,b).

Here, f(1) = 1, it means the function f passes through (1,1).

f(-3) = 17, it means the function f passes through (-3,17).

If a linear function passes through two point [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex], then the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The linear function f passes through (1,1) amd (-3,17). So, the equation of linear function is

[tex]y-1=\dfrac{17-1}{-3-1}(x-1)[/tex]

[tex]y-1=\dfrac{16}{-4}(x-1)[/tex]

[tex]y-1=-4(x-1)[/tex]

[tex]y-1=-4x+4[/tex]

Add 1 on both sides.

[tex]y-1+1=-4x+4+1[/tex]

[tex]y=-4x+5[/tex]

Put y=f(x), to write in function notation.

[tex]f(x)=-4x+5[/tex]

Therefore, required lines function is [tex]f(x)=-4x+5[/tex].

Step-by-step expation:

Answer:

The baker bought 8 pounds of apples and 4 pounds of bananas.

Step-by-step explanation:

a+b=12.

0.75a+1.05b=10.20

First, multiply 2 my 10.

75a+105b=1020.

Then multiply 1 by 75.

75a+75b=900.

Then subtract.

75a+105b=1020

75a+75b=900.

75a-75a+105b-75b=1020-900

30b=120

b=4

Substitute into (1)

a+4=12

a=8.

Hope this helps :)

Answer:

403.26 miles

Step-by-step explanation:

Given

[tex]Rate = 28.2 miles/gallon[/tex]

[tex]Gallons = 14.3\ gallons[/tex]

Required

Determine the possible distance

From the given parameters, Distance is calculated as thus:

[tex]Distance = Rate * Gallons[/tex]

[tex]Distance = 28.2 * 14.3[/tex]

[tex]Distance = 403.26[/tex]

Hence, Chase can travel a total of 403.26 miles

Answer:

hiii

the answer is option B

The answer is The median for group 1 and group 2 is the same.

The median is the middle number in a set of values when those values are arranged from smallest to largest.

The medians are very close together. Because in group 1, the median was 4.5 while in group 2 the median was 5, so I would say that is pretty close.

"The range for group 2 is greater than the range of groups 1" is not correct because in group 1 there is an x on 1 and an x on 10 while in group 2, there is a 2 x's on 2 and 2 x's on 8.

"The mode is the same for both sets of data" is not correct because in group 1 there was 3 x's on 3,4,and 7 while in group 2 there was 3 x's on 3 and 4 x's on 6.

"On average, the people in group 1 and in group 2 have about 5 electronic devices in their household" is not correct either because in group 1 there were 2 x's on 5 while in group 2 there was 1 x on 5, so this wouldn't be correct.

Hence, The option D is the correct option.

Answer:

60

Step-by-step explanation:

The part where y resides is an equilateral triangle. That means that all the angles are equal (along with all the sides). Remember that y is in a triangle.

So the three angles of the triangle = 180/3 = 60

That means that y = 60
