What is the value of t, if the value of x is 4?

T - 6 = x - 6

Answer:

[tex]a_{n}[/tex] = 5[tex]a_{n-1}[/tex]

Step-by-step explanation:

The sequence has a common ratio r between consecutive terms, that is

r = 10 ÷ 2 = 50 ÷ 10 = 250 ÷ 50 = 5

Thus the sequence is geometric with recursive formula

[tex]a_{n}[/tex] = 5[tex]a_{n-1}[/tex]

Answer:

1) Slope= 2, y-intercept=4, equation: y=2x+4

2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60

Step-by-step explanation:

Slope formula: [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex]

1. Plug in two sets of cordinates into the equation

(0,2) (2,8)

2. Solve, slope =2

3. Plug in one pair into the point slope formula

Point slope formula: [tex]y-y_1=slope(x-x_1)[/tex]

4. y-8=2(x-2)

5.y-8=2x-4

6. y=2x+4

Do the same for the other equation

Answer:

1: slope

2: y-intercept

1a: slope= 3

1b: 2

y=3x+2

2a: slope= -10

2b: 60

y= -10x+60

Answer:c.11

Step-by-step explanation:

Step-by-step explanation:

Hey there!!

Let me simply clear you.

Given,

AB: 2y+2x =8.

Let's take the equation in slope intercept form.

2y = -2x +8

[tex]y = \frac{ - 2x}{2} + \frac{8}{2} [/tex]

[tex]y = - 1x + 4[/tex]

Comparing the equation with y= mx+c, we get;

Therefore, slope of AB is -1.

Now,

Again, the another equation is,

y + x = 2

y = -x+2

Comparing, the equation with y = mx + c.

Therefore, slope of CD = -1

For parallel lines, m1=m2.

slope of AB (m1) = -1

slope of CD(m2)= -1

As m1= m2 {True}.

Therefore, They are parallel to eachother.

Hope it helps...

Answer:

Both are correct.

Step-by-step explanation:

In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.

[tex]Distance=|-2-(-7)|=5\text{ units}[/tex]

So, Laura is correct.

In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.

[tex]Distance=|2-(-9)|=|2+9|=11\text{ units}[/tex]

So, Ryan is correct.

Hence, both are correct.

Answer:

Step-by-step explanation:

This problem is on rate.

firstly we have to find the rate at which 1 ton is sold

given that 3/8 ton is sold for $24

hence 1 ton will be sold for X

cross multiply

X = 24/3/8

inverse the denominator and multiply the result with the numerator we have

X= 24*8/3

X= $64

Now having found out that 1 ton cost $64

2 tons will cost =64*2

                         = $128

Therefore at this rate two tons will cost $128

Answer:128

Step-by-step explanation:

The domain is just the x values.

Answer:

Length = 63 feet

Step-by-step explanation:

concept used:

perimeter of rectangle = 2( length + width)

____________________________________________

Given that Jason has 144 feet of material and all is used in building fence.

It means that perimeter of fence is 144 feet.

2. Width of fence = 9 feet

let the length be x

perimeter of rectangle = 2( length + width)

then perimeter of fence will be = 2(9+x)

As given above perimeter of fence is 144 feet.

2(9+x)  = 144

=> 9 + x = 144/2 = 72

=> x = 72 - 9 = 63

Length = 63 feet.

Answer:

Answer:

42 Hours.

Step-by-step explanation:

As an equation where y is the total pages and x is hours of class:

y=1+1x since she started with 1 page and does 1 page per hour.

Setting the total pages she needs as 43 (y=43) we get:

43=1+1x

Subtract one on both sides

42=1x

The 1 doesn't need to be written so

x=42

Therefore, it'll take her 42 hours to write all those notes.

Answer:

a = 6 or a = -58/8

Step-by-step explanation:

I think you meant to ask us to solve for a.

There are two cases to solve for:

5 + 8a = 53 or -(5 + 8a) = 53

8a = 48 or 5 + 8a = -53

a = 6 or 8a = -58

a = 6 or a = -58/8

Answer:

Answer: Option D.

Step-by-step explanation:

Hey there!!

Here, To find the equation of a st.line passing through point (3,1) is :

[tex](y - 1) = m1(x - 3)[/tex]

It is the first equation.

Given, Another equation is:

[tex]y = \frac{2}{3} x + 1[/tex]

It is 2nd equation.

Comparing the 2nd equation with y = mx+c we get,

Slope (m2) = 2/3.

As per the condition of parallel lines,

m1 = m2 = 2/3.

Putting, the value of m1 in equation 1st we get,

[tex](y - 1) = \frac{2}{3} (x - 3)[/tex]

or, 3 (y-1) = 2(x-3)

or, 3y - 3 = 2x - 6

[tex]y = \frac{2x - 6 + 3}{3} [/tex]

[tex]y = \frac{2}{3} x - 1[/tex]

Diving-3/3 = -1.

Therefore, y = 2/3 x - 1 is the required equation.

Hope it helps.

Answer:

we know that, 1miles/hour = 0.45m/s

or, 1meters/second = 1/0.45

1m/s = 2.22222222222

Step-by-step explanation:

Then,

72.0 meters/second = 72.0*2.22222222222

                                  =160 miles per hour.

Answer: 9 9/13, 9 5/7, 9.72, 9 9.74, 9 3/4

I can give you the easy answer of 45, but let's use prime factorization.

What number looks like it divides into 2025 easily?

Your first answer was probably 5.

2025 divided by 5 is 405.

What number looks like it divides into 405 easily?

It was probably 5 again.

405 divided by 5 is 81.

Now hopefully you know that the square root of 81 is 9.

We can bring these all out of the radical.

[tex]\sqrt{2025}[/tex]

[tex](9*5)\sqrt{1}[/tex]

We know that [tex]\sqrt{1}=1[/tex], so we can simplify this whole expression down to the outside terms, which multiply to 45.

-5418+676

-4742

:) Hope this helped

Answer:

-4742

Answer:

[tex]v = \frac{A - r}{rf}[/tex]

Step-by-step explanation:

Given

[tex]A = r + rvf[/tex]

Required

Solve for v

[tex]A = r + rvf[/tex]

Subtract r from both sides

[tex]A - r = r - r + rvf[/tex]

[tex]A - r = rvf[/tex]

Divide both sides by rf

[tex]\frac{A - r}{rf} = \frac{rvf}{rf}[/tex]

[tex]\frac{A - r}{rf} = v[/tex]

Reorder the expression

[tex]v = \frac{A - r}{rf}[/tex]

At this point, we;ve solved for v

x = 4 or x = 0

Hope that helps!
