4(4)=3y-7
16=3y-7
+7 +7
23=3y
---. ----
3. 3
7.6=y

so that's basically what you do for the rest of the numbers

How can you compare and order integers? Provide an example
antiseptic1488 [7]

You can both compare and order integers by subtracting them:

  • If the difference is zero, as the name suggests...there's no difference! So, the integers are the same. For example, you have 3-3=0,\ 6-6=0,\ -17-(-17)=0
  • If the difference is positive, then the first integer is bigger than the second. For example: 5-2=3>0,\ 18-(-2)=20>0,\ -3-(-10)=7>0 and we deduce that 5 is greater than 2, 18 is greater than -2 and -3 is greater than -10
  • If the difference is negative, then the first integer is less than the first. For example, if we invert the previous differences, we have 2-5=-3 and we deduce that 2 is less than 5, -2 is less than 18 and than -10 is less than -3

Write an equation of the line that passes through the given point and is parallel to the given line.
9966 [12]

Answer : <em>Equation of line is</em> y=Equation of line is y=\frac{2}{3}x+\frac{-5}{3}

Step-by-step explanation:

Theory :

Equation of line is given as y = mx + c.

Where, m is slope and c is y intercepted.

Slope of given line : y = \frac{2}{3}x+1 is m= \frac{2}{3}

We know that line : y = \frac{2}{3}x+1 is parallel to equation of target line.

therefore, slope of target line will be \frac{2}{3}.

we write equation of target line as y= \frac{2}{3}x+c

Now, It is given that target line passes through point ( -5,-2)

hence, point ( -5,-2) satisfy the target line's equation.

we get,

y= \frac{2}{3}x+c

-2= \frac{2}{3} \times -5+ c

-5= \frac{-10}{3}+c

c= \frac{-5}{3}

thus, Equation of line is y=Equation of line is y=\frac{2}{3}x+\frac{-5}{3}

Evaluate each expression if a = 4.1, b = 5.7, and c=0.3.<br> 4. a+b-c <br> 5. 10-(a+b)<br> 6. B- c+2
posledela

Answer:

  • a+b-c = 9.5
  • 10-(a+b) = 0.2
  • b-c+2 = 7.4

Step-by-step explanation:

4)

Given the expression

a+b-c

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

a+b-c = 4.1+5.7-0.3

          =  9.8 - 0.3

          = 9.5

5)

Given the expression

10-(a+b)

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

10-(a+b) = 10 - (4.1+5.7)

              = 10 - 9.8

              = 0.2

6)

Given the expression

b-c+2

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

b-c+2 = 5.7 - 0.3 +2

          = 5.4 + 2

           = 7.4
