Answer:

(b - 4)(b + 1)

Step-by-step explanation:

b² - 3b - 4

Factor by determining which numbers add up to -3 and multiply to equal -4.

-4 + 1 = -3

-4 × 1 = -4

Therefore, in factored form, the equation would be:

(b -4)(b + 1)

Answer:

The parking lot does not form a rectangle.

Step-by-step explanation:

Given: One pair of opposite sides of parking lot are 100 yards long. The other two sides are 60 yards long.

The distance from one end of the longer side to the opposite end of the shorter side is 120 yards.

To find: If the distances given form a right triangle?

Also, to find the hypotenuse and the numbers which represent the two sides.

Solution:

In a triangle, if the square of the length of the longest side is equal to the sum of the squares of the other two sides, then the triangle is said to be a  right angled triangle.

[tex](60)^2+(100)^2=3600+10000=13600\\(120)^2=14400\\\therefore (60)^2+(100)^2\neq (120)^2[/tex]

So, the triangle is not a right angled triangle.

So, none of the angles of the parking lot forming a quadrilateral is equal to [tex]90^{\circ}[/tex].

Hence, the parking lot is not a rectangle although the opposite sides are equal.

(A quadrilateral in which opposite sides are equal such each angle is [tex]90^{\circ}[/tex] is a rectangle )

The distances given do not form a right triangle.

Answer:

x = -8

Step-by-step explanation:

1/4x +2= -5/8x - 5

Add 5/8x to each side

1/4x +5/8x +2= -5/8x+5/8x - 5

1/4x+5/8x +2=  - 5

Subtract 2 from each side

1/4x+5/8x +2-2=  - 5-2

1/4x+5/8x =  - 7

Get a common denominator

1/4 *2/2 x + 5/8x = -7

2/8x + 5/8x = -7

7/8x = -7

Multiply each side by 8/7

8/7x * 7/8x = -7 *8/7

x = -8

Answer:

x=-8

Step-by-step explanation:

1/4x+2=-5/8x-5

find l.c.m=8

multiply through by l.c.m which is 8

x/4×8+2×8=-5x/8×8-5×8

2x+16=-5x-40

2x+5x=-40-16

7x=-56

divide both sides by 7

7x/7=-56/7

x=-8

d represents the common difference between consecutive terms in the sequence, that is

d = 30 - 27 = 33 - 30 = 36 - 33 = 3

Answer:

About 4.5

Step-by-step explanation:

Since the full base has length 8, half of it must have length 4. Now, using the Pythagorean theorem, you can find x:

[tex]x=\sqrt{6^2-4^2}=\sqrt{36-16}=\sqrt{20}\approx 4.5[/tex] or answer choice D

Answer:

n = - 5

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex]\frac{a^{m} }{a^{n} }[/tex] ⇔ [tex]a^{(m-n)}[/tex]

Consider the left side

[tex]\frac{y^4.y^{n} }{y^2}[/tex]

= [tex]\frac{y^{4+n} }{y^2}[/tex]

= [tex]y^{4+n-2}[/tex]

= [tex]y^{2+n}[/tex], then

[tex]y^{2+n}[/tex] = [tex]y^{-3}[/tex]

Since the bases on both sides are the same, equate the exponents

2 + n = - 3 ( subtract 2 from both sides )

n = - 5

Answer:

Let's get all of the z terms on one side. When we do so we get tz + cz - 6z = -83. We can factor the left side as z(t + c - 6) = -83 so our answer is z = -83(t + c - 6).

For each year since 1970, passenger car fuel efficiency has increased by 0.29 miles per gallon.

Answer: The answer is C. For each year since 1970, passenger car fuel efficiency has increased by 0.29 miles per gallon.

Step-by-step explanation:

In a linear model of the form y = mx + b, m is the slope and b represents the y-intercept.

In this situation, 0.29 is the slope.

The slope is the ratio of the change in y to the change in x.

In context, the slope indicates an increase of 0.29 miles per gallon per year after 1970.

Therefore, the slope means that for each year since 1970, passenger car fuel efficiency has increased by 0.29 miles per gallon.

Answer:

The answer is option 1.

Step-by-step explanation:

You have to use Distributive Laws,

[tex]a(b + c) = ab + ac[/tex]

So for this question :

[tex](6r - 1)( - 8r - 3)[/tex]

[tex] = 6r( - 8r) + 6r( - 3) - 1( - 8r) - 1( - 3)[/tex]

[tex] = - 48 {r}^{2} - 18r + 8r + 3[/tex]

[tex] = - 48 {r}^{2} - 10r + 3[/tex]

The product of the expression is (6r - 1) (-8r - 3) is negative 48 r squared minus 10 r + 3.

Algebraic expression is a mathematical equation in which one or both sides is an algebraic expression, such as 2x + 7y = 3.

According to this question, the following expression is given:

(6r - 1) (-8r - 3)

Therefore, the product of the expression is -48r² -10r + 3

Answer:

f(3π/4) = -π

A = π

b = 2

Step-by-step explanation:

Given that the function follows the form: f(x) = A sin(bx), then f(0) = 0. Given that the period is π, then at x = π/4 the function reaches a maimum, at x = π/2, f(x) = 0, and at x = 3π/4, f(x) reaches a minimum, which have to be π*(-1) = -π

Given the general equation: f(x) = A sin(bx), its period is calculated as:

period = 2π/b

which is equal to π, then:

2π/b = π

b = 2

Replacing x = π/4 into the equation of the function, we get:

A sin(2(π/4)) = π

A sin(π/2) = π

A = π
