Answer:

-2 • (3x - 493)

Step-by-step explanation:

(1006 - 4x) - 2 • (x + 10)

Pulling out like terms :

3.1 Pull out like factors :

986 - 6x = -2 • (3x - 493)

Final result :

-2 • (3x - 493)

write an equation to represent the relationship, and find the amount of peanut butter used to make 25 cracker packages. the tabl

Nadusha1986 [10]

We are given 4 points.

$(\frac{1}{2},2)$

$(\frac{5}{8},\frac{5}{2})$

$(\frac{3}{4},3)$

$(\frac{7}{8},\frac{7}{2})$

Using this, we can make an equation.

$y=4x$

I got $m=4$ by using the slope formula.

$m=\frac{2.5-2}{0.625-0.5}$

$m=\frac{0.5}{0.125}$

$m=4$

So the equation we have is $y=4x$

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for $y$ , which is the number of cracker packages.

$25=4x$

$x=\frac{25}{4}$

We need to use $\frac{25}{4}$ teaspoons of peanut butter to make 25 packages of crackers.

Hope this helps.

頑張って!

I need help with this as well ty lol

Pie

so you use the formula a^2 + b^2 = c^2
so C will be JL
13m^2 + 17m^2 = c^2
458 m = c^2

to leave C alone you need to square root it

√458m = √c^2
21.4 = C

Log5 (x squared - 9) = 0

andreev551 [17]

Answer:

$x=3,\:x=-3$

Step-by-step explanation:

Given the equation

$\log _{10}\left(5\right)\left(x^2-9\right)=0$

Divide both sides by $\log _{10}\left(5\right)$

$\frac{\log _{10}\left(5\right)\left(x^2-9\right)}{\log _{10}\left(5\right)}=\frac{0}{\log _{10}\left(5\right)}$

Simplify

$x^2-9=0$

Add 9 to both sides

$x^2-9+9=0+9$

Simplifying

$x^2=9$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$x=\sqrt{9},\:x=-\sqrt{9}$

$\sqrt{9}\:=3$

$-\sqrt{9}=-3$

Therefore,

$x=3,\:x=-3$
