Answer: No solution

Steps: 8x + 3 = 8x + 27

Subtract 8x from both sides: 8x + 3 - 8x = 8x + 27 - 8x

Simplify: 3 ≠ 27

The sides are not equal so therefore there is no solution.

Plz mark brainliest:)

nekit [7.7K]

Step 1:

a) Write the quadratic model

a = -15.64

b = -1.24

c = 5.23

$P(t)=-15.64t^2\text{ - 1.24t + 5.2}3$

b) t = 0.30

$\begin{gathered} P(t)=-15.64t^2\text{ - 1.24t + 5.2}3 \\ =\text{ -15.64 }\times0.3^2\text{ - 1.24}\times\text{ 0.3 + 5.2}3 \\ =\text{ -1.4076 - 0.372 + }5.23 \\ =\text{ 3.45} \end{gathered}$

c) t = 0.52 seconds

$\begin{gathered} p(t)=-15.64t^2\text{ - 1.23t + 5.23} \\ =\text{ -15.64}\times0.52^2\text{ - 1.23}\times0.52\text{ + 5.23} \\ =\text{ -4.23 - 0.64 + 5.23} \\ =\text{ 0.36} \end{gathered}$

d) 0.30 is more likely to be relaible.

$\begin{gathered} p(t)\text{ = 1} \\ p(t)=-15.64t^2\text{ - 1.23t + 5.23} \\ 1=-15.64t^2\text{ - 1.23t + 5.23} \\ -15.64t^2\text{ - 1.23t + 4.23 = 0} \\ t\text{ = 0.48222} \\ \text{t = 0.48 seconds} \end{gathered}$

Pls answer fast (√3 + √11)² + (√3 - √11)²

Masja [62]

(√3 + √11)² + (√3 - √11)²

(a+b)² = a² + b² + 2ab
( a - b )² = a² + b² - 2ab

Now ,

(√3 + √11)² + (√3 - √11)²

(3 + 11 + 2√3√11)+ (3 +11 - 2√3√11)

14 + 2√33+ 14 - 2√33

14 + 14 = 28

Hence , The value of (√3 + √11)² + (√3 - √11)² is 28 .

you run 1 mile in 8 minutes at a constant speed. How far do you run in 1 minute? write an equation to represent how far you can

Montano1993 [528]

Answer:

0.125

0.125x = Distance Traveled in Miles

0.125 * 11 = 1.375 Miles Ran

Step-by-step explanation:

First divide 1 mile by 8 minutes

1 mi / 8 min = 0.125 mi

Then you simply show 0.125 * x (x being the number you insert to find the distance) = How far you ran

0.125x = Distance Traveled in Miles

Finally you insert 11 for x and multiply to find the distance

0.125 * 11 = 1.375 Miles Ran
