Mathematics
1 answer:
Jobisdone [24]3 years ago
5 0

Answer:

s =  \frac{9± \sqrt{ - 39} }{4}

Step-by-step explanation:

\frac{3(s - 5)}{4 - 3}  =  \frac{4s \times (s - 3)}{2}

➡️ \frac{3(s - 5)}{1}  = 2s \times (s - 3)

➡️ 3s - 15 = 2 {s}^{2}  - 6s

➡️ 3s - 15  -  2 {s}^{2}  + 6s = 0

➡️ 9s - 15 - 2 {s}^{2}  = 0

➡️ - 2 {s}^{2}  + 9s - 15 = 0

➡️ 2 {s}^{2}  - 9s + 15 = 0

➡️ s =  \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2}  - 4 \times 2 \times 15} }{2 \times 2}

➡️ s =  \frac{9± \sqrt{81 - 120} }{4}

➡️ s =  \frac{9± \sqrt{ - 39} }{4}

➡️ s∉ℝ

Use the compound interest formula A =​P(1 + ​r) t and the given information to solve for r.
Dmitry [639]

Answer:

Rounding to nearest hundredths gives us r=0.06.

So r is about 6%.

Step-by-step explanation:

So we are given:

A=P(1+r)^t

where

A=2300

P=1600

t=6.

A=P(1+r)^t

2300=1600(1+r)^6

Divide both sides by 1600:

\frac{2300}{1600}=(1+r)^6

Simplify:

\frac{23}{16}=(1+r)^6

Take the 6th root of both sides:

\sqrt[6]{\frac{23}{16}}=1+r

Subtract 1 on both sides:

\sqrt[6]{\frac{23}{16}}-1=r

So the exact solution is r=\sqrt[6]{\frac{23}{16}}-1

Most likely we are asked to round to a certain place value.

I'm going to put my value for r into my calculator.

r=0.062350864

Rounding to nearest hundredths gives us r=0.06.

What number is the opposite of -69?<br><br> What number is the opposite of the opposite of -69?
grandymaker [24]

Answer:

69, -69

Step-by-step explanation:

If the number is positive, the opposite of it is the same number, but negative.

If the number is negative, the opposite of the number is the same number, but positive.

So, -69 would be 69.

69 is the opposite of -69, so the opposite of 69 would go back to -69.

Express each equation in slope-intercept form. -2x+4y=68, 13x+4y=284
lara31 [8.8K]
To get the answer we have to tranform into y=ax+b form
-2x+4y=68          /+2x
4y=2x+68          /:4
y=\frac{1}{2} x+17  - its the result

13x+4y=284           /-13x
4y=-13x+284        /:4
y=- \frac{13}{4}+ 71
y=-3 \frac{1}{4}x+71 - its the result
