Answer:

the answer is no solution

Step-by-step explanation:

7+−3x=x+(−4)(2)+(−4)(x)(Distribute)

7+−3x=x+−8+−4x

−3x+7=(x+−4x)+(−8)(Combine Like Terms)

−3x+7=−3x+−8

−3x+7=−3x−8

Step 2: Add 3x to both sides.

−3x+7+3x=−3x−8+3x

7=−8

Step 3: Subtract 7 from both sides.

7−7=−8−7

0=−1

Find the distance CD rounded to the nearest tenth<br> C=(10,-1) and D=(-6,3)

Fynjy0 [20]

Answer:

CD = 16.5

Step-by-step explanation:

To find the distance between two points, use this formula: $L = \sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }$

point C can be info set 1: (10, -1) x₁ = 10 y₁ = -1

point D can be info set 2: (-6, 3) x₂ = -6 y₂ = 3

Substitute the information into the formula

$L = \sqrt{(x_{2} -x_{1})^{2}+(y_{2} -y_{1})^{2} }$

$CD = \sqrt{(-6 -10)^{2}+(3 -(-1))^{2} }$ Simplify inside each bracket

$CD = \sqrt{(-16)^{2}+(4)^{2} }$ Square the numbers

$CD = \sqrt{256+16 }$ Add inside the root

$CD = \sqrt{272}$ Enter into calculator

$CD = 16.5$ Rounded to the nearest tenth, the first decimal

The distance CD is 16.5.
