What is the equation of a line passing through the points (-3,<br> -2) and (2, 0)?
Lostsunrise [7]

Answer:

y=0.400x+-0.800

Step-by-step explanation:

Given the following question:

point A = (-3, -2)
point B = (2, 0)

To write the equation of the line that passes through two points we have to write the points in slope intercept form.

Formula for slope intercept:

y=mx+b

M is equal to the slope of the two points, so first we need to fine the slope of the two points.

(-3,-2)=(x1,y1)
(2,0)=(x2,y2)

m=\frac{y2-y1}{x2-x1}
m=\frac{0--2}{2--3} =\frac{2}{5}
m=\frac{2}{5} =0.400

y=mx+b
y=-2
m=0.400
x=-3
-2=0.400(-3)+b
0.400\times-3=-1.20
-2+1.2=-0.800
b=-0.800

y=0.400x+-0.800

Hope this helps.

Find the coordinates of the vertices of the figure formed by each system of inequalities.
siniylev [52]

Answer:

D(1, –5), (7, 1), (–11, 7)

Step-by-step explanation:

The given inequalities are:

y + x ≥ –4

y ≥ x – 6

3y + x ≤ 10

We graph the inequalities as shown in the attachment.

The coordinates of the vertices of the figure formed by the given system of inequalities are:

(1, –5), (7, 1), (–11, 7)

The correct choice is D.

What is the following product? (2 square root 7+3 square root 6)(5 square root 2+4 square root 3)
Xelga [282]

(2\sqrt7+3\sqrt6)(5\sqrt2+4\sqrt3)\qquad\text{use distributive property}\\\\=(2\sqrt7)(5\sqrt2)+(2\sqrt7)(4\sqrt3)+(3\sqrt6)(5\sqrt2)+(3\sqrt6)(4\sqrt3)\\\\=10\sqrt{14}+8\sqrt{21}+15\sqrt{12}+12\sqrt{18}\\\\=10\sqrt{14}+8\sqrt{21}+15\sqrt{4\cdot3}+12\sqrt{9\cdot2}\\\\=10\sqrt{14}+8\sqrt{21}+15\sqrt4\cdot\sqrt3+12\sqrt9\cdot\sqrt2\\\\=10\sqrt{14}+8\sqrt{21}+(15)(2)\sqrt3+(12)(3)\sqrt2\\\\=\boxed{10\sqrt{14}+8\sqrt{21}+30\sqrt3+36\sqrt2}
