A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is Y=-x+5. Thus, the correct option is C.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The position of Allien in the coordinate plane is (0,5), the coordinate of the rocket is (5,0). The slope between the two  is,

Slope, m = (0 - 5)/(5 - 0) = -5/5 = -1

The equation of the line can be written as,

y = -1x + C

substitute any one of the point in the equation,

0 = -1(5) + C

0 = -5 + C

C = 5

Hence, the equation of the line is Y=-x+5. Thus, the correct option is C.

Answer:

-[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We can find the slope of the line by using the point slope formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

If we plug in your numbers, we get:

[tex]\frac{4-2}{4-8}[/tex], or -[tex]\frac{2}{4}[/tex], or -1/2.

Answer:

c = 13

Step-by-step explanation:

c = 6(3) - 5

c = 13

Answer:

C. c=13

Step-by-step explanation:

This is how I figured it out:

1. I took the equation (c=6a-b) and I replaced the letters with the numbers given. (a=3 & b=5) so I got the new equation c=6(3)-5.

2. I used PEMDAS (parentheses, exponents, multiplication, division, addition and subtraction. Since we have multiplication and subtraction needed multiplication is shown before subtraction in PEMDAS so we would figure out 6(3) first which is equal to 18.

3. Now we have the new equation of c=18-5. Since subtraction is left we would take away 5 from 18 and now we have the final answer of 13. So the equation would now look like this: c=13. It's pretty obvious that c=13 that c has the value of 13.

Answer:

(5,1) (4,2)

Step-by-step explanation:

Her final exam will be her 6th exam. To determine the her final exam  score we can use this equation:

Mean = All scores/6

70 = (58 + 73 + 85 + 83 + 79 + x )/6  ⇒ x stands for the final exam mark

70 = 378 + x /6   ⇒ Multiple both sides by 6 to cancel it out

420 = 378 + x   ⇒ Subtract 378 from both sides to isolate x

420 - 378 = x

42 = x

Therefore, she must get at least 42% on her final to maintain a 70% average.

Answer:

B & D

Step-by-step explanation:

Options B and D have a solution from the given set of equations.

We need to find from the given which equation does not have solutions.

Solve the given equation for x. If you get any value then the equation has a solution.

From option (A):

-60x+32=-60x+60

⇒-60x+60x=60-32

By simplifying the above equation we get no x value. So, there are no solutions.

From option (B):

-60x+32=32x-60

⇒-60x-32x=-60-32

⇒-92x=-92

⇒x=1

From option (C):

-60x+32=-60x-32

By simplifying the above equation we get no x value. So, there are no solutions.

From option (D):

-60x+32=32x+60

⇒-92x=28

⇒x=0.304

Therefore, options B and D have a solution.

Answer:

  (a, b, c, d) = (2, -3, -2, 2)

Step-by-step explanation:

The horizontal segment where y=3 extends from x = -2 to x = 2. These are the values of c and d, respectively.

The slope of the left piece is up 2 for over 1, so is 2/1 = 2, the value of a.

The slope of the right piece is down 3 for over 1, so is -3/1 = -3, the value of b.

So, we have ...

Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.

have a great day :)

Because multiplication is the converse of division,

x/y=z

x=yz

Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.

Just like addition is the converse of subtraction.

If x/y=z,

then x=yz.

If x divided by y is equal to z, then x equals y times z. These are the rules of arithmetic. If they weren't true the universe would fall apart! The rule can be used as a check that you have the right answer.

Therefore converse of division is the answer.
