Solve the following:<br> a) 4x 3= 2x + 7<br><br> b) 2x+6= 7x14

nikdorinn [45]

<h2><u>Correct question</u> : 4x - 3 = 2x + 7 </h2>

<h2><u>Solution</u> : 4x - 3 = 2x + 7 </h2>

$4x - 2x = 7 + 3 \\ \\ 2x = 10 \\ \\ x = \frac{10}{2} \\ \\ x = 5.$

<h2><u>Correct Question</u> : 2x + 6 = 7x - 14</h2>

<h2><u>Solution</u> : 2x + 6 = 7x - 14</h2>

$2x - 7x = - 14 - 6 \\ \\ - 5x = - 20 \\ \\ x = \frac{20}{5} \\ \\ x = 4.$

The following triangles are similar. Find side AB.

tankabanditka [31]

Answer:

Step-by-step explanation:

Set up ratios of corresponding sides. x+2 is to 6 as 2 is to 3:

$\frac{x+2}{6}=\frac{2}{3}$

Now cross multiply to get

3(x + 2) = 12 and

3x + 6 = 12 so

3x = 6 and

x = 2. That means that side AB, x + 2, is 2 + 2 which is 4

Through: (3, -5) and (0, -2) <br><br><br>please add the steps please.

Vlad [161]

1: -5 = 3m + c
2: -2 = 0 + c

From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m

-5 = 3m - 2
m = -1

The equation of line is y = -x - 2
