Answer 1

Answer:

Answer: 9.40492 units

Step-by-step explanation:

Use the Pythagorean Theorem to solve for the length of each leg of the triangle, then add all lengths to find the perimeter

Line WX has a length of $\sqrt{3^(2)+3^(2) } =√(18) =3√(2)$

Line WY has a length of $\sqrt{3^(2)+1^(2) } =√(10)$

Line XY has a length of $\sqrt{2^(2) } = 2$

The perimeter of the triangle is $3√(2) +√(10) +2=9.40492$

Which is an equation in point-slope from for the given point and slope point (7,4)slope:6

Answers

Answer: y-4=6(x-7)

The formula for point slope form is:

$y- y_(1) =m(x- x_(1))$

where

m=slope
$y_(1)=$ known y-coordinate
$x_(1)=$ known x-coordinate

now lets input the information that we know into the equation. We know the slope is 6. Our known x coordinate is 7, and our known y coordinate is 4.

y-4=6(x-7)

pont slope from is y=mx+b where slope=m and b=y intercept
we are given that slope=6
subsiutte
y=6x+b
we are given the point (7,4)
(x,y)
so x=7
y=4 is one solution
subsitutute
4=6(7)+b
4=42+b
subtract 42 from both sides
-40=b
the equation is y=6x-40

Two positive integers are 3 units apart on a number line. Their product is 108.Which equation can be used to solve for m, the greater integer?

m(m – 3) = 108

m(m + 3) = 108
(m + 3)(m – 3) = 108
(m – 12)(m – 9) = 108

Answers

Equation that can be used to solve m, if m is the greater integer is:
m(m+3)=108
Solution is: m=12 ( 12*9=108)
Answer: A) m(m-3)=108
