Answer:

x = 10 is your answer

- Explain -

Step 1: subtract 1 from both sides (subtraction of equality)

which will give us:

2x = 21 - 1

which equals to

2x = 20

Step 2: Divide both sides by 2

which is

2x/2 = 20/2

2/2 = 1 and 20/2 = 10

Therefore the answer is x = 10

How would you solve this(what is the equation of the line that passes through the point (3,4) and has a slope of -2/3?)//delta m

Answer:

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

Step-by-step explanation:

y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.

4 = $-\frac{2}{3}$ (3) + b

-2/3 times 3 is -2 so you can fill that in place.

4 = -2 + b

6 = b

So the y-intercept is 6 now we can complete the equation.

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

Hope that helps and have a great day!

Can somebody solve this?

Answer:

∠ABC = 46°

Step-by-step explanation:

DB and BC are of same length (radius), making it an isosceles triangle.

The base of the triangle is the same at 23°, a total of 46°.

180° - 46° = 134°

But we need ∠ABC, and since points DBA lie on the circumference, it's a straight line.

Therefore, 180° - 134° = 46°
