Answer:

4x - 5y - 9 = 0

\frac{9}{4}

\frac{-9}{5}

Step-by-step explanation:

The equation of a straight line passing through the points (-4,-5) and (1,-1) is given by \frac{y - (-5)}{-5-(-1)} =\frac{x-(-4)}{-4-1}

⇒ \frac{y+5}{-4} =\frac{x+4}{-5}

⇒ 5y + 25 = 4x + 16

⇒ 4x - 5y - 9 = 0 ....(1) (Answer)

Now, this above equation can be represented as

\frac{x}{\frac{9}{4} } + \frac{y}{\frac{-9}{5} } =1

Therefore, the x-intercept is \frac{9}{4} (Answer)

And the y-intercept is \frac{-9}{5}. (Answer)

What is the length of DE?? Thx :)
Alex

Answer:

10

Step-by-step explanation:

Your scale factor is 3/2, because when you compare AC and DF, the ration is 18/12, or 3/2. We can set up a proportion:

3/2=15/x

We cross multiplu

3x=30

x=10

So, the length of DE is 10 units.

Hope this helps!

What is the equation of a horizontal line that has a y-intercept of 3?
Ira Lisetskai [31]

Answer:

y = 3

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

here the line passes through (0, 3) with y- coordinate 3

y = 3 ← is the equation of the horizontal line

Why is it important to make sure the decimal point is in the correct spot whn adding and subtracting decimals?
blsea [12.9K]
A decimal in the wrong place can change the value of a number completely for example
0.5 can be converted to 50 cents or 1/2 but if you change the decimal 0.05 converts to 5% or 1/20.

Help please and thank you
aksik [14]
Remember
(a^b)^c=a^{bc}
and
\frac{x^a}{x^b}=x^{a-b}


so

\frac{(7^2)^5}{7^{-6}}=
\frac{7^{2*5}}{7^{-6}}=
\frac{7^{10}}{7^{-6}}=
7^{10-(-6)}=
7^{10+6}=
7^{16}

the answer is D
