Answer:

[tex]\boxed {j = -20}[/tex]

Step-by-step explanation:

-Solve for the value of [tex]j[/tex]:

[tex]20 - 17j = -18j[/tex]

-Take [tex]18j[/tex]and add it to [tex]17j[/tex]:

[tex]20 - 17j + 18j = -18j + 18j[/tex]

[tex]20 + j = 0[/tex]

-Subtract both sides by [tex]20[/tex]:

[tex]20 - 20 + j = 0 -20[/tex]

[tex]\boxed {j = -20}[/tex]

So, the value of [tex]j[/tex] is [tex]-20[/tex].

Answer:

-6

Step-by-step explanation:

subtract 3 from both sides and that leaves 3x=-18

then divide 3 by -18 and that equals -6

Answer:

x= -6

Step-by-step explanation:

Step 1: Subtract 34 from both sides.

3x+34−34=16−34

3x=−18

Step 2: Divide both sides by 3.

3x /3  =  −18 /3

x=−6

Answer:

the answer is -1

Step-by-step explanation:

Answer: x = 0

Step-by-step explanation: Firstly, set them equal to each other.

7x - 1 = 6x - 1

Now, subtract 6x from both sides:

x - 1 = -1

Add 1 to both sides:

x = 0

And if you need to know what type of function it is, it is an infinite function because if you plug in 0:

7(0) - 1 = 6(0) - 1

You get:

-1 = -1

If both sides are the same, it is an infinite function.

Hope this helps!

Answer:

the answer is y=4/5x-3

The equation of the line shown in the graph would be, [tex]y = \dfrac{4}{5} x - 3[/tex]

Hence, option 1 is true.

Given that;

Two points on the line are (5, 1) and (0, -3).

Used the concpet of the equation of the line,

The equation of a line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, [tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]

Now,

Since, The equation of line passes through the points (5, 1) and (0, -3)..

So, We need to find the slope of the line.

Hence, the slope of the line is,

[tex]m = \dfrac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]

[tex]m = \dfrac{(- 3 - 1)}{(0 - 5)}[/tex]

[tex]m = \dfrac{(- 4)}{( - 5)}[/tex]

[tex]m = \dfrac{(4)}{( 5)}[/tex]

Thus, The equation of the line with slope 4/5 is,

[tex]y - 1 = \dfrac{4}{5} (x - 5)[/tex]

[tex]y - 1 = \dfrac{4}{5} x - 4[/tex]

[tex]y = \dfrac{4}{5} x - 4 + 1[/tex]

[tex]y = \dfrac{4}{5} x - 3[/tex]

Therefore, The equation of the line will be;

1) [tex]y = \dfrac{4}{5} x - 3[/tex]

So, option 1 is true.

Answer:

A. 5*(-8)*2=-80

B. Forgot about the signs

Step-by-step explanation:

Product of Signed Integers

The product of two integers with like (same) signs is positive. The product of two integers with different signs is negative.

A.

Alex is simplifying the product 5*(-8)*2. It can be done in any order, for example, let's multiply 5*(-8) first.

The numbers have different signs, so the product is negative and 8*5 =40, thus:  5*(-8)=-40.

Now we finish the operation multiplying (-40)*2. They have different signs, thus the result is negative and (-40)*2=-80, thus:

5*(-8)*2=-80

B.

If Alex found the opposite of the correct product, that is, 80 is more likely to have been the result of forgetting about the signs. He probably just multiplied the numbers regardless of their signs.

Answer:

He could walk  173 [tex]\frac{1}{3}[/tex] miles in 10 days

Step-by-step explanation:

To solve this problem let us use the ratio method

∵ Billy walked 52 miles in 3 days

∵ We need to find how many miles could he walk in 10 days

→ Use the ratio method

→ Miles  →  Days

→  52     →   3

→   x       →   10

→ x is the number of miles

→ By using cross multiplication

∵ x × 3 = 52 × 10

∴ 3x = 520

→ Divide both sides by 3 to find x

∴ [tex]\frac{3x}{3}=\frac{520}{3}[/tex]

∴ x = 173 [tex]\frac{1}{3}[/tex] miles

∴ He could walk  173 [tex]\frac{1}{3}[/tex] miles in 10 days

Answer:

Step-by-step explanation:

To write the inequality, we need to first caculate the amount of money that Lia would ACTUALLY earn each week and compare that to her goal of $600.

We cannot actually get the amount of money that Lia would get because we don't know her sales so we will represent the sales with a X.

450+ X(5%).  -This the amount of money she would egt from her sales. We need to also figure out 5% of 450 to solve the next part of the equation. That is $22.5. 600-450=150/22.5= 6.6666- which is about 7 sales.

Answer:

-29.7

Step-by-step explanation:

Assuming sea level is at 0, you would first subtract 25.65 from 0 to indicate diving 25.65 feet BELOW 0. Then, you subtract 16.5 from that. Then, add 12.45 to that number to get the answer after the diver rose 12.45 feet.

0-25.65= -25.65

-25.65-16.5= -42.15

-42.15+ 12.45= -29.7

OR 29.7 feet below sea level.

Answer:

Step-by-step explanation

Let's say d = distance, r = speed and t = time

We know the distance formula is :

distance = speed x time

d = r multiplied by t

d = rt

If the speed is 15km/hr, the time would be 30 minutes shorter.

Since d = rt,

90 = 15t

t = 6,

This means the time taken for the bus to complete the journey at 15km/hr would be 6hrs.

Originally though, the journey takes 30 minutes longer.

So we can say t = 6.5 hrs , and we know d = 90

Now we use the distance formula:

d = rt, since we want to find the original speed, we want to find r.

Speed = distance/time

r = d/t

r = 90/6.5

r = 180/13

Therefore the original speed is 180/13 km/hr

Given

cost of ticket=$60

a. the cost of x tickets is

C(x)=60x

b. sale tax of 5.5% of $60 is 5.5/100*60

   0.55*60=$3.3

processing fee = $8

the total cost T(a) for a dollars spent on tickets.

T(a)=60a+3.3+8

T(a)=60a+11.3

c. Find (T ∘ C)(x).

T(x)=60x+11.3

d. Find (T ∘ C)(6)

T(6)=60*6+11.3

T(6)=360+11.3

T(6)=$371.3

This means that for 6 tickets with a tax of 5.5% and a processing fee of $8 the cost will be $371.3

Peak of Mount everest = 5 1/2 miles above sea level

Bottom of Mariana trench = 6 9/10 miles below sea level

If mount everest is placed at the bottom of Mariana trench

. It's be will be :

Since sea level could be considered as a 0 point;

Adding the height and depth of both should give us the depth below sea level:

(6 9/10 + 5 1/2) miles

6 + 5 (9/10 + 1/2)
