Answer:

x = 3

Step-by-step explanation:

(2x + 1) = 9

(2*3 + 1) = 9

(6 + 1) = 9

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in

nydimaria [60]

Answer:

$50$

Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

Step-by-step explanation:

So he wants to keep his consumption of carbs between the inequalities:

$110$

So, let's solve both inequalities.

$110$

Subtract 10 from both sides:

$100$

Divide both sides by 2:

$50$

$2x+10$

Subtract 10 from both sides:

$2x$

Divide both sides by 2:

$x$

So, our inequality is now:

$110$

Since we solved the equations:

$50$

Written as a compound inequality, this is:

$50$

In other words, Ryan would like to eat more than 50 carbs per day, but no more than 150 carbs per day.

So, Ryan's total carb intake must be between 50 and 150 carbs.

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new e

slamgirl [31]

Answer:

$New = -92\frac{1}{8}$

Step-by-step explanation:

Given:

$x = -75\frac{3}{4}$ --- Position

$\triangle x = -16\frac{3}{8}$ --- Change

Required

Find the new position

The new position is calculated as:

$New = x + \triangle x$

$New = -75\frac{3}{4} - 16\frac{3}{8}$

$New = -75.75 - 16.375$

$New = -92.125$

$New = -92\frac{125}{1000}$

$New = -92\frac{1}{8}$

What is the area of the triangle ?

bezimeni [28]

from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.

the third point, (0,-6), to the base is your height

use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8

area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12

Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis
