Given -10x-2y=16 prove y=-5x-8

Answer:

A) y=3x+1

Step-by-step explanation:

Use the formula y=mx+b

m is the slope and b is the y intercept

the graph starts on 1 on the y axis so you replace 1 for b

the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.

Answer: I will give you the answer in fraction form and in decimal form. Here is 1/6 divided by 12... Answer: 1/72

Answer:

let angle be x

Step-by-step explanation:

relationship between perpendicular and hypotenuse is given by sin angle

sin x =p/h

sin x=13/26

x=sin-¹(13/26)=30°

2.relationship between perpendicular and base is given by tan angle

tan x =p/b

tan x =7/16

x=tan -¹(7/16)=23.63°

3.relationship between between perpendicular and base is given by tan angle

tan x =p/b

tanx=31/50

x=tan-¹(31/50)=31.8°

4.relationship between base and hypotenuse is given by cos angle

cos x =b/h

cos x=5/7

x=cos-1(5/7)=44.4°

5.relationship between perpendicular and hypotenuse is given by sin angle

sin x =p/h

sin x=4/14

x=sin-¹(4/14)=16.6

6..relationship between base and hypotenuse is given by cos angle

cos x=6/7

x=cos-¹(6/7)=31.0027

7.relationship between perpendicular and base is given by tan angle

.tanx=29/37

x=tan-¹(29/37)=38.09

8.relationship between perpendicular and hypotenuse is given by sin angle

.sin x=43/60

x=sin-¹(43/60)=45.78

9..relationship between base and hypotenuse is given by cos angle

cos x=32/44

x=cos-¹(32/44)=43.34

Step-by-step explanation:

2l + 2w = P

2w = P - 2l

w = P - 2l / 2

Therefore, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given equation is

[tex]2L + 2w = P\\\\2(L+w)=P\\\\L+w=\frac{1}{2}P\\\\w=\frac{1}{2}P-L\\\\w=\frac{P-2L}{2}\\\\w=P-\frac{1}{2}L[/tex]

Hence, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

Answer: i think 80 not sure tho i failed my last test

Step-by-step explanation:

Answer:

80  in

Step-by-step explanation:

Because this is a right triangle we can find the length of the missing side using the Pythagorean Theorem

Given the hypotenuse and one leg we do

[tex]c^2-b^2=a^2[/tex]

where c = hypotenuse and b = leg

[tex]82^2=6724\\18^2=324\\6724-324=6400\\\sqrt{6400} =80[/tex]

so we can conclude that the missing side length is equal to 80

Answer:

Step-by-step explanation:

Formula: share/# of parts × amount = Total

# of parts= 3+7+9= 19

so= 3/19 × $2500 = $7500

= $7500 × 3

= $22500

do the same for the others to get the shared. oh and also 3/19 is a fraction. hope it was helpful.✌

Answer:

the first one

Step-by-step explanation:

Hey There!

Look at the image for the rule of a 30- 60 - 90 triangle

x = 5

the hypotenuse would be x2 so 10

the longer leg would be x[tex]\sqrt{3}[/tex]

So the first triangle is the right answer

The first triangle in the figure is a 30°-60°-90° triangle.

A triangle is a polygon with three sides and three angles.

Given are triangles, we need to see which of them are a 30°-60°-90° triangle,

So,

In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse.

So you have to choose one with 5 & 10.

Use the Pythagorean theorem to calculate the remaining side

a² + b² = c²

5² + b² = 10²,   so b² = 100-25  √b²=√75  so √(25)(3)  

b= 5√3

Hence, the first triangle in the figure is a 30°-60°-90° triangle.
