Answer:

y = 6

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (-4,y) and (-2,8). Substitute m = 1 and solve for y.

$m = \frac{y_2-y_1}{x_2-x_1}\\\\ 1 = \frac{y-8}{-4--2}\\\\ 1 =\frac{y-8}{-2}\\\\-2=y-8\\\\6=y$

In the Sahara Desert one day it was 136oF. In the Gobi Desert a temperature of

coldgirl [10]

Answer: $186^{\circ}F$

Step-by-step explanation:

Given : In the Sahara Desert one day it was 136°F.

In the Gobi Desert a temperature of -50°F was recorded.

Clearly , 136°F> -50°F

Then, the difference between these two temperatures will be :-

$136^{\circ}F-(-50)^{\circ}F\\\\=(136+50)^{\circ}F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^{\circ}F$

Hence, the difference between these two temperatures = $186^{\circ}F$

7 over radical 90 write in simplist form

Arte-miy333 [17]

Simplify the square root
$7 \sqrt{90} = 7\sqrt{3 { }^{2} \times 10}$
Separate the numbers in the square root to look like this
$7 \sqrt{3 ^{2} } \sqrt{10}$
Because three is squared, it cancels out the square root
$7 \times 3 \sqrt{10}$
Simplify to get your answer:
$21 \sqrt{10}$
