Compare the table and equation. x y
4 12
5 15
6 18

Equation: y = 3x

Which representation has the greatest slope?

The equation has the greatest slope.
The table has the greatest slope.
The table and equation have the same slope.
Their slopes cannot be determined.

Answers

Answer:

The table and equation have the same slope

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

Step 1

Find the slope of the table

we have

$A(4,12)\ B(5,15)$

Substitute the values

$m=(15-12)/(5-4)$

$m=(3)/(1)=3$

Step 2

Find the slope of the equation

we have

$y=3x$ ------> the equation represent a linear direct variation

The slope is equal to $m=3$

therefore

The table and equation have the same slope

Karen and Daryl work for a delivery service. Karen made 15 more deliveries than Daryl. If Daryl made d deliveries, which expression represents the number of deliveries Karen made?a. d divided by 15B. 15 + dC. 15 • dD. d- 15

Answers

Given : Karen and Daryl work for a delivery service.Karen made 15 more deliveries than Daryl. Let d be the deliveries made by Daryl .We need to find the expression that represents the number of deliveries Karen made

Karen made 15 more deliveries than Daryl. The mathematical symbol for more than is addition or + sign .

15 more than d can be represented by 15+d.

Option B. 15 + d is the right answer.

The answer is B 15+d

Y=3x-5
3y-12x=-6
Substitution method

Answers

Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 3x−5.
y=3x−5
3(3x−5)−12x=−6

Simplify each term.
y=3x−5
9x−15−12x=−6

Add 9x and −12x to get −3x.
y=3x−5
−3x−15=−6

move -15 to the right-hand side of the equation by adding 15 to both sides.
y=3x−5
−3x=15−6

Subtract 6 from 15 to get 9.
y=3x−5
−3x=9

Simplify

(−3,−14)

1y = 3x - 5 ⇒ 1y - 3x = - 5 ⇒ 3y + 9x = 15
3y - 12x = -6 ⇒ 3y - 12x =   6 ⇒ 3y - 12x = 6
       21x = 21
      21    21
   x = 1
      y - 3(1) = -5
          y - 3 = -5
   +3   +3
   y = 2
   (x, y) = (1, 2)

Jerome is writing a number in scientific notation. The number is greater than one million and less than ten million. What will be the exponent in the number Jerome writes?PLEASE HELP!!!!(by that i mean i want the answer)

Answers

The exponent in the number Jerome writes will be anywhere between 6 to 7.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Jerome is writing a number in scientific notation.

Let's suppose the number is x

The number x is greater than one million and less than ten million.

In scientific notation:

$\rm 10^6\leq x\leq 10^7$

We can say that from the above inequality that the exponent of the number will be between 6 to 7.

Thus, the exponent in the number Jerome writes will be anywhere between 6 to 7.

One million: 10^6

Ten million: 10^7

So the exponent will be anywhere between 6 and 7, inclusive

Mindy wants to solve the following system using the elimination method: y = x − 4
y = 2x − 3

What number should the equation y = x − 4 be multiplied by to eliminate x?

Answers

The Mindy should multiplied the second equation with number 2 to elminate the x term and solve the system using the elimination method.

What is elemination method?

The elemination method is used to solve the system of equation and to find the values of unknown variable.

To solve the equations using the elemination method, follow the following steps-

Multiply all the equation, with a number such that the one of the comon variable of both the equation gets the same coefficient.
Substract the equations to elminate one of the variable.
Solve the equation for remaining variable.
Substitude the value of this variable in any equation to find the value of other variable.

The system of equation, Mindy wants to solve using the elimination method are,

$y = x - 4\ny = 2x - 3$

To perform the elemation method, the terms of varible of x in both the equation should be same.

The coefficient of x in second equation is 2. Thus, the equation y = x − 4 should be multiplied by 2 to eliminate x.

$2y =2 (x - 4)\n2y =2x - 8$

Hence, the Mindy should multiplied the second equation with number 2 to elminate the x term and solve the system using the elimination method.

y = x − 4 // * (-2) ( multiply by -2 )
y = 2x − 3

-2 y = -2 x + 8
y = 2x − 3
------------------ sum
-y = -2x + 2x +8 - 3
-y = 0 + 5 //x has been eliminated

answer: multiply by -2
