Answer:

We simplify the equation to the form, which is simple to understand

5x+15=4x-12

We move all terms containing x to the left and all other terms to the right.

+5x-4x=-12-15

We simplify left and right side of the equation.

+1x=-27

then divide both sides of the equation by 1 to get x.

x=-27

. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.

Alekssandra [29.7K]

Answer: $3^{\circ}C$

Step-by-step explanation:

Given

The temperature on Monday was $-5^{\circ}C$

By Tuesday, it becomes $-2^{\circ}C$

Change in temperature is the difference between the two temperatures.

$\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C$

Therefore, the change in temperature is $3^{\circ}C$ .

Find the distance between these points. A(5,8), B(-3,4)

konstantin123 [22]

Answer:

Distance between the points is 8.94 units

Step-by-step explanation:

General formula:

${ \boxed{ \bf{distance = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y _{1} - y _{2} ) }^{2} } }}}$

substitute:

${ \sf{ = \sqrt{ {(5 - ( - 3))}^{2} + {(8 - 4)}^{2} } }} \\ = { \sf{ \sqrt{64 + 16} }} \\ = { \sf{ \sqrt{80} }} \\ = 8.94 \: units$
