Answer:

Step-by-step explanation:

alright! let's do it

y =mx + b

the slop would be "m"

y = 4x+b

and then, let's plot -2 to x and 4 to y.

why? well to find " b " as y intercept

4 = 4(-2) +b

4 = -8 +b

+8 +8 both side add 8 to keep the same between 2 sides

12 = b

so:

y = 4x +12

and done! hope you enjoy!

For this case we must solve the following equation:

$\frac {5} {7} + \frac {x} {2} = 2- \frac {x} {7}$

So, we have:

$\frac {10 + 7x} {14} = \frac {14-x} {7}\\7 (10 + 7x) = 14 (14-x)$

We apply distributive property to both sides of the equation:

$70 + 49x = 196-14x$

We add 14x to both sides of the equation:

$70 + 49x + 14x = 196\\70 + 63x = 196$

We subtract 70 to both sides of the equation:

$63x = 196-70\\63x = 126\\x = \frac {126} {63}\\x = 2$

So, the solution is: $x = 2$

Answer:

$x = 2$

The side lengths of a square was dilated by the scale factor of 4/5. The new area of the square is 64 cm2. Find the original sid

PSYCHO15rus [73]

Solve for side

a = 8 cm

A Area 64 cm^2

Using the formula

A = a^2

a = $\sqrt{A} = \sqrt{64} = 8cm$

Decide whether ABC is a right angle triangle

muminat

The triangle is not a right angle

AC = 22 - 8 - 5 = 9
AC² = AB² + BC²
81 = 64 + 25
81 isn't equal to 89, the triangle is not a right angle
