Answer:

0.8333 as a decimal or [tex]\frac{5}{6}[/tex] as a fraction.

Step-by-step explanation:

First, you would divide -5/8 and -3/4 in the parenthesis. Right after, you would divide the numbers you have in the parenthesis and you would end up with 0.8333 or [tex]\frac{5}{6}[/tex] both are equal.

Answer:

[tex]3d - 9[/tex]

Given:

Jack's plan charges a fee of $24 plus $0.08 per minute he talks.

Jill's plan charges a fee of $10 plus $0.15 per minute she talks.

To find:

The equation which is used to determine when Jack and Jill's plans will be the same.

Solution:

Let t be time in minutes.

Jack's plan charges a fee of $24 plus $0.08 per minute he talks. So, function for Jack's plan is

[tex]f(t)=24+0.08t[/tex]

Jill's plan charges a fee of $10 plus $0.15 per minute she talks. So, function for Jill's plan is

[tex]g(t)=10+0.15t[/tex]

Jack and Jill's plans will be the same, if [tex]f(t)=g(t)[/tex].

[tex]24+0.08t=10+0.15t[/tex]

Therefore, the required equation is [tex]24+0.08t=10+0.15t[/tex].

Answer:

27

Step-by-step explanation:

5*6=30

6/2=3

30-3=27

[tex]5w - \dfrac{w}{x} [/tex]

w=6

w=6x=2

Let's put value of w and x

→[tex]5 \times 6 - \dfrac{6}{2} [/tex]

Step 1:

→[tex]30 - 3[/tex]

Step 2:

→[tex]\purple{27✓}[/tex]

Answer:

$308 - 14r

Number of weeks = 22 weeks

Step-by-step explanation:

Given that:

Amount kept in bank = $308; which should be withdrawn weekly at $14 per week

Total amount in bank - weekly withdrawal * number rof weeks

Let number of weeks = r

$308 - 14r

When will the money run out

$308 - 14r = 0

-14r = - 308

Divide through by 14

14r/13 = 308/14

r = 22

Tne entire money can be withdrawn for 22 weeks at $14 per week without any leftover.

Answer:

see below

Step-by-step explanation:

The rate of change is

f(x2) - f(x1)

------------------

x2-x1

Since this is a line we can pick any two points on the line, one befre x=1 and one after x=1

Let x=0 and x=2

f(2) - f(0)

-------------

2-0

4-2

-------

2

2/2

1

The rate of change is 1

y=-4x-8

To find x-intercept / zero , substitute y=0

0=4x-8

Move Variable to the left-hand side and change its sign

-4x=-8

Divide both sides of the equation by -4

Answer: x=2

Answer:

18g - 8

Step-by-step explanation:

So the angle is a 90º angle because of that square so you subtract 36 by 90 which will become 54

Hope this helps!

Answer:

x= 54º

Step-by-step explanation:

Let's break this down...

First, you have to look at the whole angle and if you are lucky you find a square.

The square is always equal to 90º

So to find x you need to subtract 90 and 36 which is 54

Hope this helps!

Step-by-step explanation:

Answer:

In expanded form:

2^3 = 2 * 2 * 2 = 8

In standard form :

2^3

Step-by-step explanation:

Given the numbers in range (0 to 10)

Write an exponential expression :

Choosing from the range for the Base and the exponent

Base = 2

Exponent = 3

where ; 2 = base. ; 3 = exponent

In expanded form:

2^3 = 2 * 2 * 2 = 8

In standard form :

2^3

Step-by-step explanation:

y = 2x - 3

.....20 characters smh

A y-intercept is the value at which x = 0.

(4,0) is not a y-intercept because x = 4.

(-1, 1) is not a y-intercept because x = -1.

(0,0) is a y-intercept because x = 0.

(0, -7) is a y-intercept because x = 0.

(-2, 2) is not a y-intercept because x = -2.

(0, -0.25 is a y-intercept because x = 0.
