Find the slope of the line that passes through the two points below." (7,-1) and (9,0)

Mathematics

1 answer:

Stells [14]2 years ago

3 0

Answer:

1/2 or 0.5 (same value, different form)

Step-by-step explanation:

Ok...since I can't actually graph it, we can make a table out of it....

x y

7 -1

9 0

From -1 to 0, we add 1 (this is for the y section)

From 7 to 9, we add 2 (this is for the x section)

Now all we have to do is divide the y with the x

y/x = 1/2

The slope will be 1/2 (fraction form) 0.5 (decimal form)

Hope this helped!

Michelle brought an apple cut in 4 for $0.10 per piece. How much should she pay for 3 dozen pieces

Leya [2.2K]

Answer:

$0.90

Step-by-step explanation:

$\frac{4}{10}=0.4$

3 dozen = 36

$\frac{36}{0.4} =\frac{y}{0.1}$

0.4 × y = 36 × 0.1

0.4y = 3.6

0.4y ÷ 0.4 = 3.6 ÷ 0.4

y = 9

Given that for simplicity that the number of children in a family is 1, 2, 3, or 4, with probability 1/4 each. Little Joe (a boy

horsena [70]

Answer: $\dfrac{1}{4}$

Step-by-step explanation:

Given : The number of children in a family is 1, 2, 3, or 4.

Little Joe (a boy) has no brothers. But he may have sisters.

The sample space for the number of child in Joe's family : {B, BG, BGG, BGGG}, where G represents girl and B represents boys.

Then , for the probability that he is an only child, favorable outcome = B

Thus, the probability that he is an only child is given by :-

$=\dfrac{\text{Favorable outcome}}{\text{Total outcomes}}=\dfrac{1}{4}$

Hence, the probability that he is an only child = $\dfrac{1}{4}$

17. Explain whether 11t - 4t is equivalent to 4t - 11t.

nydimaria [60]

Answer:

So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )

Step-by-step explanation:

Given:

$11t - 4t$ ..............Equation ( 1 )

$4t - 11t$ ................Equation ( 2 )

To Find:

Whether Equation ( 1 ) is Equivalent to Equation ( 2 )

Support your answer by evaluating the expression for t = 2.

Solution:

For t=2 Equation ( 1 ) we get

$11t - 4t=11(2) - 4(2)=22-8=14$

For t=2 Equation ( 2 ) we get

$4t - 11t=4(2) -11(2)=8-22=-14$

From above we get two different values

So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
