What is the equation, in point slope form, for a line that passes through the points (4,5) and (-3,-1)

mylen [45]

Answer:

-6

-7

Step-by-step explanation: (4,5) and (-3,-1)

Y2 represents -1
Y1 represents 5
X2 represents -3
X1 represents 4

Y2 - Y1

X2 - X1

-1 - 5

-3 - 4

-6

-7

Hope this helps you!!! :)

What is x when f(x)=1? (This means determine the input that gives an output of 1.)

Harrizon [31]

Answer:

0 or undefined

Step-by-step explanation:

As you said, it could be anything, and there is proof that could be anything, which I'm sure your teacher would appreciate (writing proofs is a level of mathematical achievement that only hardcore math nerds can do, and it'd be super cool if you could write one yourself) A proof is basically a written mathematical description of exactly why something is the way it is.

But if you want to choose just one answer, I'd choose either 0 or undefined. If the answer is something that's bubbled in, then choose 0.

In the simplest assumed equation f(x) = 1 + x, x would have to = 0.

If we're looking at this graphically, y=1 (remember y=f(x)) graphed is a straight line that never crosses the x axis, which would mean there's no possible x value that would work for that equation.

Also, depending on what level math you're in, you may not even be working with undefined answers yet, in which case, your best answer would again be 0.

Hope this helped!

10. WHAT is any trapezoid. A straight line

Svetradugi [14.3K]

(a) ET = 18 and WE = 12

(b) FA = 16/3

HF = 8/3

ET = 8

WE = 4

Explanation:

WT = 30 ( WE + ET = 30)

WE = 30 - ET

2FA = 3HF

FA = 3/2HF

WE =?, ET = ?

Line WH, EF and TA are parallel to each other.

(a)

ΔWTA and ΔWHA are congruent to each other

Therefore, by congruency

$\frac{WE}{ET} = \frac{HF}{FA}$

So,

30 - ET/ ET = HF / 3/2HF

30 - ET / ET = 2HF / 3HF

30 - ET / ET = 2/3

On solving the above equation we get, ET = 18

WE = 30 - ET

WE = 30 - 18 = 12

Therefore, ET = 18 and WE = 12

(b)

HA = 8 ( HF + FA = 8)

HF = 8 - FA

WT = 12 ( WE + ET = 12 )

WE = 12 - ET

GA = 2WG

HF, WA, WE, ET = ?

ΔWHA and ΔGFA are congruent

So,

$\frac{HF}{FA} = \frac{WG}{GA}$

8 - FA / FA = WG / 2 WG

On solving the above equation we get,

FA = 16/3

HF + FA = 8

HF + 16/3 = 8

HF = 8/3

ΔWTA and ΔWEG are congruent

So,

$\frac{WE}{ET} = \frac{WG}{GA}$

12 - ET / ET = WG / 2WG

On solving the above equation, ET = 8

WE = 12 - ET

WE = 12 - 8

WE = 4

Therefore, FA = 16/3

HF = 8/3

ET = 8

WE = 4

5/3+(-7/6) reduce to simplest form

julsineya [31]

Answer:

$\frac{5}{3} + (-\frac{7}{6})$ reduced to the simplest form is $\frac{1}{2}$

Step-by-step explanation:

$\frac{5}{3} + (-\frac{7}{6})$

First, rearrange the fractions so that they have the same denominator. We do this by finding the common multiple of 3 and 6 and multiplying the numerators by the number of times it takes to get to the denominator when multiplying.

$\frac{10}{6}+(- \frac{7}{6} )$

Now, since 7/6 is negative, then it would just be like subtracting 7/6 from 10/6.

$\frac{10}{6} -\frac{7}{6} = \frac{3}{6}$

Now, all we have to do is reduce the fraction 3/6.

$\frac{3}{6}= \frac{1}{2}$

So, your final answer would be $\frac{1}{2}$
