4 (2x + 3) + 2 (x + 1) - 7

8x + 12 + 2x +  2 - 7

10x + 7

10x = -7
10x/10 = -7/10

x = -7/10

hope this helps

Write the equation in slope-intercept form of the line that contains the points (4, -7) and (0, 5).
LenaWriter [7]
The slope intercept form is y=mx+b
The slope formula is m=(y2-y1)/(x2-x1)
So; 5-(-7) / 0-4= -3
Then you use one of the points to find b; I’ll use 0 and 5 (the first number is x and the second number is y)
5=(-3)(0)+b
5=0+b
5=b
Finally you plug in your two values
Y= -3x+5

Hope this helps :)

Find the circumference of a circle with a diameter of 15 inches... Round to the nearest tenth and include units in your answer..
rosijanka [135]

Answer:

<em>47. 1 inches ; where inches ⇒ units</em>

Step-by-step explanation:

Consider the Circumference as such;

Diameter - 15 inches,\\Circumference - 2\pi r, r - radius,\\\\2\pi r = \pi d, d - diameter ( considering, 2 * r = diameter )\\\\Circumference = \pi * d = \pi * diameter = \pi * 15 = ( About ) 47.1 inches\\Solution; Circumference = ( About ) 47.1 inches

<em>From this we can tell that ⇒ Answer; 47. 1 inches, where inches - units</em>
