Answer:
y+5 = 1/4(x+7)
Step-by-step explanation:
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y- -5 = 1/4(x - -7)
y+5 = 1/4(x+7)
Hello There!
Point-Slope:
y-y₁=m(x-x₁)
y-(-5)=1/4(x-(-7)
y+5=1/4(x+7)
y=1/4x+1.75+5
y=1.4x+6.75

Answer:
289/216
Step-by-step explanation:
add the parentheses first
(2/3+3/4)×(3/6+4/9)=
17/12×17/18
then multiply
17/12×17/18=
286/216
2/3 + 3/4
= 2 × 4/3 × 4 + 3 × 3/4 × 3
= 8/12 + 9/12
= 8 + 9/12
= 17/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
Add: 3/6 + 4/9
= 3 × 3/6 × 3 + 4 × 2/9 × 2
= 9/18 + 8/18
= 9 + 8/18
= 17/18
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 9) = 18. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 9 = 54. In the next intermediate step, the fraction result cannot be further simplified by canceling.
2 = 17/12 × 17/18
= 17 × 17/12 × 18
= 289/216
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(289, 216) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

in a right triangle with a 30 degree angle, draw the perpendicular bisector of the hypotenuse. find the ratio of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg
The perpendicular bisector of the of the hypotenuse side forms a right
triangle with the hypotenuse and the longer leg of the of the triangle.
The ratio, of the length of the segment cut from the perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, is 1 : 3
Reason:
The given parameters are;
An acute angle of the right triangle = 30°
Let R represent the length of the hypotenuse side, we have;
The length of the longer leg, [tex]L_{ll}[/tex] = R × cos(30°) = [tex]\dfrac{\sqrt{3} }{2} \cdot R[/tex]
The perpendicular bisector forms a right triangle with a leg length = R/2
The length of the hypotenuse formed by the bisector is therefore;[tex]R_{bisector} = \dfrac{\dfrac{R}{2} }{cos(30^{\circ})} = \dfrac{\dfrac{R}{2} }{\dfrac{\sqrt{3} }{2} } = \dfrac{R}{\sqrt{3} }[/tex]
The length, L, of the segment cut by the hypotenuse and the longer leg is therefore;
[tex]L= R_{bisector} \times sin(30^{\circ}) = \dfrac{1}{2} \times \dfrac{R}{\sqrt{3} } = \dfrac{R}{2 \cdot \sqrt{3} }[/tex]
The ratio, of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, r, is therefore;
[tex]r = \dfrac{L}{L_{ll}} = \dfrac{ \dfrac{R}{2 \cdot \sqrt{3} }}{\dfrac{\sqrt{3} }{2} \cdot R} = \dfrac{2 \cdot R}{2 \cdot \sqrt{3} \times \sqrt{3} \times R } = \dfrac{1}{3}[/tex]
The ratio, of the lengths, r = [tex]\dfrac{1}{3}[/tex], therefore, r = 1:3

Answer:
12
Step-by-step explanation:
18/2-3/.75=15/1.25
The average speed of Even between two checkpoints is 9 miles per hour.
What is an average speed?The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.
We know that the average speed formula is given as,
Average speed = Total distance / Total time
Running a marathon is Evan. Between two checkpoints, he wants to compute his average speed. He takes 0.75 hours to go to the 3-mile checkpoint and 2 hours to get to the 18-mile milestone.
The average speed is given as,
Average speed = 18 / 2
Average speed = 9 miles per hour
The average speed of Even between two checkpoints is 9 miles per hour.

The diagonal of one side of a rhombus are of equal length. Find the measure of angles of the rhombus.
Consider ABCD is a rhombus
We know that
All sides are equal in rhombus
=> AB=BC=CD=DA
and AC and BD are digonals
Given that
Diagonal and the side of the rhombus are equal.
=> AB = BC = CD = DA = AC
Diagonal AC divides the rhombus into two triangles .
They are ∆ BAC and ∆ DAC
In triangle BAC
BA=BC=AC,(Given)
=> < BAC=<ABC= < ACB =60°………(1)
Similarly in ∆DAC ,
DA=DC=AC
=><DAC=<ACD=<ADC=60°……….(2)

y = 1/2 x + 3
domain means all valid values for x.
range means all valid values for y (the functional results).
x = 0
y = 1/2 × 0 + 3 = 3
x = 1
y = 1/2 × 1 + 3 = 3.5
x = 2
y = 1/2 × 2 + 3 = 4
x = 3
y = 1/2 × 3 + 3 = 4.5
x = 4
y = 1/2 × 4 + 3 = 5
so, the range is 3, 3.5, 4, 4.5, 5
y = x - 6
x = 10
y = 10 - 6 = 4
x = 12
y = 12 - 6 = 6
x = 14
y = 14 - 6 = 8
x = 16
y = 16 - 6 = 10
x = 18
y = 18 - 6 = 12
so, the range is 4, 6, 8, 10, 12
