Which of the following equations has a slope of -2 and passes through the point (2,3)?
ryzh [129]

Option C (Same as Option D)

<h2>Explanation:</h2>

Option C and D are the same, so I'll assume you made a mistake when writing this question. However, let's figure out which of the following equations has a slope of -2 and passes through the point (2,3):

A. y = -2x + 6

B. y - 3 = -2(x + 2)

C. y = -2x + 7

<em />

<em>All these equations have a slope of -2.</em>

FROM OPTION A:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+6 \\ \\ 3=-4+6 \\ \\ 3=2 \ False!

Since 3\neq 2 then the line doesn't pass through the point (2, 3)

FROM OPTION B:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3-3=-2((2)+2) \\ \\ 0=-2(4) \\ \\ 0=-8 \ False!

Since 0\neq -8 then the line doesn't pass through the point (2, 3)

FROM OPTION C:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+7 \\ \\ 3=-4+7 \\ \\ 3=3 \ True!

Since 3\neq 3 then the line passes through the point (2, 3)

<em>Finally, the equation that has a slope of -2 and passes through the point (2,3) is Option C (Same as Option D)</em>

How to work out 1204 divided by 7

Someone please help me

Answer:

  8. Louis

  9. Rose; Raymond

Step-by-step explanation:

8. An exponent represents the number of times the base appears as a factor in the product.

We use a coefficient to signify repeated addition: 3x means x+x+x.

We use an exponent to signify repeated multiplication. x³ means x·x·x.

So, the expression ...

  4^2\cdot 4^5\text{  means  }(4\cdot4)\cdot(4\cdot4\cdot4\cdot4\cdot4)

You can see that the factor 4 appears 7 times in the product, so would be represented in exponential form as ...

  4^2\cdot4^5=\boxed{4^7}

Louis has correctly observed this fact. In general, we see that multiplying powers of the same base causes those powers to be added.

__

9.

<u>Part A</u>. Rose is correct for the same reason as in problem 8.

  5^5 · 5^2 = 5^(5+2) = 5^7

<u>Part B</u>. Raymond is correct. We know that division cancels similar terms from the numerator, so ...

  \dfrac{7^9}{7^5}=\dfrac{7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7\cdot7}{7\cdot7\cdot7\cdot7\cdot7}=7\cdot7\cdot7\cdot7=7^{9-5}=7^4

__

The rules of exponents we're using here are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

7j+5-8k<br> when j=0.5 and k=0.25
Tomtit [17]

Answer:

<em>6.5</em>

Step-by-step explanation:

To perform this kind of exercise, it is necessary to replace the value indicated in each variable each time you find the variable in the equation.

7j+5-8k

If j=0.5 and k=0.25, replace the value of each variable.

7(0.5)+5-8(0.25)=

now perform the indicated operations

7(0.5)+5-8(0.25)=3.5+5-2=6.5
