Answer:

24/x-8 = 4

Multiplying both the sides with x-8

24 = (x-8)*4

24 = 4x - 32

24 + 32 = 4x

56 = 4x

56/4 = X

14= X

The expression 700(1.005644)4x shows the quarterly interest rate Letrice earns after x years. Which expression shows the x isola

shutvik [7]

Answer: $700( 1.02276784858 )^x$

Step-by-step explanation:

Here, the given expression,

$700(1.005644)^{4x }$

Where x is the number of years.

We can write,

$700(1.005644)^{4x } = 700[(1.005644)^4]^x$ ( Because $(a^m)^n = a^{mn}$ )

⇒ $700(1.005644)^{4x } = 700(1.02276784858)^x$

Since, In the expression $700(1.02276784858)^x$ , x is isolated in exponent and it is also equivalent to the given expression.

Therefore, it is our required answer.

What is the slope of the line that passes through the points (3,-2) and (9,-2)? 0 3 -3 undefined

SVETLANKA909090 [29]

Answer:

$\boxed{\textsf{ The slope of the line is $\bf{\dfrac{3}{2}}$.}}$

Step-by-step explanation:

Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (3,-2) and (9,-2) .As we know that the slope of the line is given by $\tan\theta$

<u>Slope of a line is :-</u>

$\qquad\boxed{\boxed{ \sf Slope =\dfrac{ y_2-y_1}{x_2-x_1}=\tan\theta }}$

On using this formula we can find the slope of the line .

<u>Putting the respective values :-</u>

$\sf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\sf\implies Slope = \dfrac{ 9-3}{2+2} \\\\\sf\implies Slope =\dfrac{6}{4}\\\\\sf\implies\boxed{\pink{\sf Slope = \dfrac{3}{2} }}$

Use the explicit formula an = a1 + (n - 1) • d to find the 350th term of the sequence below. 57, 66, 75, 84, 93, ... A. 3234 B.

mylen [45]

To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198

Temka [501]

Answer:

£55.25

Step-by-step explanation:

Cost after reduction

=Cost before sale - Reduction in cost

= 85 - 35% of 85

= 85 - 0.35*85

= 85 - 29.75

= £55.25
