Answer

True

Step-by-step explanation:

Cause 2×X=2x and 2×3=6

so total = 2× + 6 =5× + 6 - 3x

Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Ulleksa [173]

Answer:

The equation of line is $5(y-4) = 2( x+2)$

$2 x-5 y+24=0$

Step-by-step explanation:

Given slope is $m = \frac{2}{5}$ and passes through (-2,4)

$y-y_{1}= m(x-x_{1} )$

$y-4 = \frac{2}{5}(x-(-2))$

$5(y-4) = 2( x+2)$

$2 x-5 y+24=0$

A farm stand sold 12 ears of corn for 4$ .the farm stand sold 180 ears of corn at the same rate

oksano4ka [1.4K]

To answer this first we set up a proportion and then solve. Lets do it:-

$\frac{4}{12}= \frac{x}{80}$

Cross Multiply:-

80 · 4 = 320

Divide:-

420 ÷ 12 = 60

So, 180 ears of corn are for $60.

$\displaystyle\\
15(2a - 2) = 5(a^2 -1) \\ \\ 
30a - 30 = 5a^2-5\\\\
-5a^2 + 30a -30 + 5 =0\\\\
-5a^2 + 30a -25 =0 ~~~~~\Big| \times (-1) \\\\
5a^2 - 30a +25 = 0~~~~~\Big| : 5 \\\\
a^2 - 6a +5 = 0 \\ \\ 
a_{12}= \frac{-b\pm \sqrt{b^2-4ac}}{2a}= \frac{6\pm \sqrt{36-20}}{2}= \frac{6\pm \sqrt{16}}{2}=\frac{6\pm 4}{2}= \boxed{3\pm 2} \\ \\ 
a_1 = 3+ 2 = \boxed{5}\\\\
a_2 = 3-2 = \boxed{1}$
