Line r and m are parallel. Find the value of y.

Answers

Answer 1

Answer:

y=8

Step-by-step explanation:

the angle that is equal to 10x-3 and the angle that is equal to 7x+45 are equal to each other because they are corresponding angles so we setup an equation which would be

10x-3=7x+45

step 1

add 3 to each side

-3+3 = they cancel out

45+3=48

now we have

10x=7x+48

step 2

subtract each side by 7x

7x-7x cancels out

10x-7x=3x

3x=48

step 3

divide each side by 3

3/3 cancels out

48/3=16

so x =16

now we plug it into to 10x+3

10x16=160 160-3= 157

so the angle that is equal to 157 and the one that is equal to 3-y are supplementary angles so they will add up to equal 180 so to solve y we setup the equation which would be

180=157+3y-1

step 1 combine like terms

157-1=156

180=156+3y

step 2 subtract each side by 156

156-156 cancels out

180-156=24

so now we have

24=3y

next we divide each side by 3

3/3 cancels out

24/3=8

y=8

hope this makes sense :D

A. Y = 1/3(3)^x
B. Y= 3(1/3)^x
C. Y= (1/2)^x +2
D. Y=(2)^x - 1

Answers

Answer:

Step-by-step explanation:

Look at the graph, it passes to (0,3), so you need to replace that coordinate into A,B,C,D. Then you can see, there is only B and C satisfies.

[tex]Y=3(\frac{1}{3} )^{0}=3.1=3.[/tex]

and

[tex]Y=(\frac{1}{2} )^{0}+2=1+2=3[/tex]

Next step, you can see when x approach to infinite then Y approach to 0.

Hence, we will take limit of B and C, if limit B or C equals to 0 then we will choose.

[tex]\lim_{x \to \infty} {3(\frac{1}{3})^x=3. \lim_{x \to \infty} {(\frac{1}{3})^x=3.0=0[/tex]

and

[tex]\lim_{x \to \infty} {[(\frac{1}{2})^x+2]}= \lim_{x \to \infty} {(\frac{1}{2})^x}+ \lim_{x \to \infty} {2}=0+2=2[/tex]

We can see that only B is satisfied.

Answer:

t - 4 ≤ 4

Step-by-step explanation:

Hi I really need help with this

The number line represents t ≤ 8

Since the line is on 8 and moving towards the negative part of the number like (less than)

The equivalent equation will be;

t - 4 ≤ 4

Ads 4 to both sides

t-4+4≤4+4

t ≤ 8

Since the solution is similar to the expression above hence t - 4 ≤ 4 is correct

If an object is projected upward with an initial velocity of 125 ft per sec, its height h after t seconds is h= - 16t+ 125t. Find the height of the object after 2 seconds.

Answers

Answer:

h(t) = -16t^2+125t

We need to find h(t) when t = 4 s:

h(4) = -16*4^2+125*4

h(4) = 244 ft

The height of the object after 4 seconds is 244 feet.
