12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (-3,4)$

Replacing these values in the distance formula

$D =\sqrt{(-1-(-3))^2+(2-4)^2}$

$D =\sqrt{(-1+3)^2+(-2)^2}$

$D =\sqrt{(2)^2+4}$

$D =\sqrt{4+4}$

$D =\sqrt{8}$

$D= 2.8284$

Hence the Distance is 2.82 units

Write an equation of the line in point-slope form that passes through the given points (-3,2) (5,5)

daser333 [38]

I think it is: y=0.375x+3.125

a=(5-2)/(5- -3)=3/8=0.375

Find b

(5)=0.375(5)+b
(5)=1.875+b
5-1.875=b
b=3.125

Which equation represents a line that passes through (2, - 1/2) and has a slope of 4 ?

solmaris [256]

Answer:

y=4x-8.5

Step-by-step explanation:

Use point- slope form, since you are given one point and one slope.

y-y₁=m(x-x₁)

Plug coordinates and slope in.

y-(-1/2)=4(x-2)

Solve

y+1/2=4x-8

y=4x-8.5

60>5(6-2x) ok help me so I can get an answer

Dima020 [189]

Inequalities are used to represent unequal expressions

The solution to the inequality is: $x > -3$

<h3>How to determine the inequality solution</h3>

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

$60>5(6-2x)$

Divide both sides of the inequality by 5

$12>6-2x$

Subtract 6 from both sides of the inequality

$6>-2x$

Divide both sides of the inequality by -2

$-3Rewrite the inequality as[tex]x > -3$

Hence, the solution to the inequality is: $x > -3$
