Answer:

The Answer is: 5.

Step-by-step explanation:

Let n = number.

The number times 31 plus 40 is equal to 200 minus the number:

31n + 40 = 200 - n

32n = 200 - 40

32n = 160

n = 5

Proof:

31(5) + 40 = 200 - 5

155 + 40 = 195

195 = 195

Hope this helps! Have an Awesome Day!! :-)

The potential in a region between x = 0 and x = 6.00 m is V = a + bx, where a = 15.4 V and b = -5.10 V/m.

Minchanka [31]

Answer:

$V(0)=15.4\\V(3)=0.1\\V(6)=-15.2$

Step-by-step explanation:

The potential in a region between x = 0 and x = 6.00 m is V = a + bx.

Put a = 15.4 V and b = -5.10 V/m.

So, $V=15.4-5.10x$

To find: Potential at x =0, 3, 6

Solution:

Potential at x = 0:

$V=15.4-0=15.4$

Potential at x = 3:

$V=15.4-5.10(3)=15.4-15.3=0.1$

Potential at x = 6:

$V=15.4-5.10(6)=15.4-30.60=-15.2$

Therefore,

$V(0)=15.4\\V(3)=0.1\\V(6)=-15.2$

50 POINTS AND MARK BRAINLIEST

givi [52]

Step-by-step explanation:

a) Using the distance formula,

$RS=\sqrt{(2-4)^{2}+(3-4)^{2}}=\sqrt{4+1}=\boxed{\sqrt{5}}\\ST=\sqrt{(4-5)^{2}+(4-0)^{2}}=\sqrt{1+16}=\boxed{\sqrt{17}}\\RT=\sqrt{(2-5)^{2}+(3-0)^{2}}=\sqrt{9+9}=\boxed{3\sqrt{2}}$

b) Using the slope formula,

$m_{\overline{RS}}=\frac{4-3}{4-2}=\boxed{\frac{1}{2}}\\m_{\overline{ST}}=\frac{0-4}{5-4}=\boxed{-4}\\m_{\overline{RT}}=\frac{0-3}{5-2}=\boxed{-1}$

c) The triangle is <em>scalene</em> because each of the sides is of a different length.

How do you do the number line of this question why do we need to flip the inequality

Phantasy [73]

I don't see an inequality, but I can tell you that the sign of the inequality is flipped whenever you multiply or divide by a negative number.
