Simplify the following expression.

HACTEHA [7]

Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49

Suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on

Nesterboy [21]

Answer: $49.7^{\circ}F$

Step-by-step explanation:

Given

The temperature on the ground is $56.9^{\circ}F$

temperature drop observed is $1.2^{\circ}F\ \text{per 1000 ft}$

The height of the plane is $6000\ ft$

The total increase in height per $1000\ ft$ is $6$ units

Temperature drop is

$\Rightarrow 1.2\times 6=7.2^{\circ}F$

The temperature at that altitude is

$\Rightarrow 56.9-7.2=49.7^{\circ}F$

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –23x + 1

Finger [1]

Answer:

Equation of other line passing through point (6 , - 11) and parallel to given line is y = - 23 x + 127 .

Step-by-step explanation:

Given as :

The equation of one line

y = - 23 x + 12

∵ The equation of line in slope-intercept form is

y = m x + c

where m is the slope of line and c is y-intercept

Now, Compare given line with standard line equation

So, The slope of given line = m = - 23

Now, Again

Other line is passing through point (6 , - 11) and is parallel to given line

so, both the lines are parallel

For parallel line condition , Slope of both lines are equal

Let The slope of other line = M

So, M = m = - 23

Now, Equation of other line passing through point (6 , - 11) and slope - 23 in slope-point form

y - $y_1$ = M × (x - $x_1$ )

i.e y - ( - 11) = (- 23) × (x - 6)

Or, y + 11 = - 23 × x + 138

Or, y = - 23 x + 138- 11

i.e y = - 23 x + 127

So, The equation of other line y = - 23 x + 127

Hence, Equation of other line passing through point (6 , - 11) and parallel to given line is y = - 23 x + 127 . Answer
