Answer:

x = -8

Step-by-step explanation:

4 (x − 1) − 4 (x + 2.5) = x − 6

Distribute

4x -4 -4x -10 = x-6

Combine like terms

-14 = x-6

Add 6 to each side

-14+6 = x-6+6

-8 =x

Answer:

-8 =x

Step-by-step explanation:

4 (x − 1) − 4 (x + 2.5) = x − 6

4x -4 -4x -10 = x-6  (Distribute )

-14 = x-6  (Combine like terms )

-14+6 = x-6+6 (Add 6 to each side)

-8 =x

Answer: The first graph

Step-by-step explanation:

Answer:

1.785 cm / min

Step-by-step explanation:

We have to the following equation:

V = A * L

The volume is equal to the area times the length, now, if we derive with respect to time we have:

dV / dt = dA / dt * L

Now, the area of a trapezoid is:

A = (Upper base + Lower base) / 2 * height

Now we have:

Upper base = 40 + h

Lower base = 40

Replacing we have:

A = (40 + h + 40) / 2 * h

A = (h ^ 2) / 2 + 40 * h

Now, we derive and we are left:

dA / dt = d [(h ^ 2) / 2 + 40 * h] / dh * dh / dt

dA / dt = (h + 40) * dh / dt

we replace dA / dt:

dV / dt = [(h + 40) * dh / dt] * L

We have that dV / dt is equal to 0.1 m ^ 3 / min, we know that 1m ^ 3 is equal to 10 ^ 6 cm ^ 3, therefore:

dV / dt = 10 ^ 5 cm ^ 3 / min

in addition L is equal to 8 m or what is equal to 800 cm, and also h at the required moment is 30 cm

we replace everything and we have:

10 ^ 5 = 800 * (30 +40) * dh / dt

dh / dt = 10 ^ 5/56000

dh / dt = 1.785 cm / min

Hey!!

Solution,

Area of a square field=6084m^2

Length(l)=?

Now,

Area of square=l^2

or, 6084=l^2

or,L=√6084

L= 78

So the length of each side of a square field is 78 m.

Hope it helps...

Good luck on your assignment

The equation is an illustration of a linear function.

The equation for the number of pages left in the book is [tex]b =p- rd[/tex]

The total number of pages is:

[tex]Total = p[/tex]

The daily rate is:

[tex]Rate = r[/tex]

So, the number of pages read in d days is:

[tex]Pages = Rate \times Days[/tex]

This gives

[tex]Pages = r \times d[/tex]

Multiply

[tex]Pages = rd[/tex]

The number of pages left (b) is then calculated as:

[tex]b =Total - Pages[/tex]

So, we have:

[tex]b =p- rd[/tex]

Hence, the equation for the number of pages left in the book is [tex]b =p- rd[/tex]

Answer:

the player can expect to turn over a black card about 400 times.

Step-by-step explanation:

the way to solve a probability question is like this:

there are 52 total cards, out of those 52 cards, half of them are black cards.

that means 1/2 of 52 = black cards

if the plays 800 times, and half of the cards are black, the player can expect to have a 50% chance of flipping over a black card.

800/50 = 400.

therefore the player can expect to have flipped a black card 400 times.

factors of 105:

1, 3, 5, 7, 15, 21, 35, 105

factors of 126:

1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

GCF: 3*7 or 21

The  GCF ( 105, 126) =  3 *7 =21.

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.

Given:

105 = 3 * 5 * 7

126 = 2 * 3* 3 *7

So, GCF ( 105, 126) =  3 *7 =21

Answer:

Step-by-step explanation:

It is a function, since each student gets only one score one final exam,]

Domain is each student,

the first to last

Range is the score each student got:

(however the scoring was made)

f(each student) is a function because each student, or each element of the domain corresponds to the score, one and only one element of the range.

Answer:

The domain of f is 'the students in Mr. Well's history class'

The range of f is 'the final exam scores'

f 'is' a function because each student, or each element of the 'domain', corresponds to 'one' element of the 'range'

Answer:

A. y=-3x+4

Step-by-step explanation:

Since the equation is in y=mx+b form, m represents the slope of a line. To solve for slope-intercept, use the equation m=(y2-x2)/(y1-x1).

[tex]m=\frac{-2-4}{2-0}[/tex]

[tex]m=\frac{-6}{2}[/tex]

[tex]m=-3[/tex]

Make sure to plug in one of the points into the equation to check if the numbers equal to one another or not.

Answer:

its rather B or C

Step-by-step explanation:

c(c)=y

so the slope is Y=2x+2

the reason why its rather B or C is because of the axis

i   dont know what belongs where

Answer:

B Maybe

Step-by-step explanation:

Answer: y=1/2x-4

Step-by-step explanation:

Since we are given the slope, we can use the slope-intercept form to find the y-intercept.

y=1/2x+b

-3=1/2(2)+b

-3=1+b

b=-4

Now that we know our y-intercept, we can fill in our slope-intercept equation.

y=1/2x-4
