Anyone know the answer

Answer:

x = -7

Step-by-step explanation:

10x + 18 = 8x + 4

take away 4 from both sides

10x + 14 = 8x

take away 10x from both sides

14 = -2x

divide botth sides by -2

x = -7

Answer:

Non-proportional relationship

Step-by-step explanation:

Proportional relationships must pass through the origin. Otherwise, at [tex]x=0[/tex], we lose the constant of proportionality, and the y-value at [tex]x=0[/tex] becomes correlated only to the y-intercept.

The format for a proportional relationships is given by [tex]y=kx[/tex], where [tex]k[/tex] is some constant referred to as the constant of proportionality.

Answer:

They will meet in 2.25 hours or 2 hours 15 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Let the number of hours at which they meet be x

In x hours, the distance traveled by Karen will be 59 * x = 59x miles

In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles

Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed

However, the sum of whatever they have traveled will be equal to the distance between them

thus;

59x + 65x = 279

124x = 279

x = 279/124

x = 2.25 hours

Answer:

expanded:

y = sin(4x)*sin(4x)*cos(3x)

need to use the product rule and chain rule

look at individual derivatives, use chain rule

d/dx sin(4x) = 4cos(4x)

d/dx cos(3x) = -3sin(3x)

put it together using product rule

dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)

simplify

dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)

answer is A.

A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

Answer:

Prime numbes

Step-by-step explanation:

Numbers whose only factors are 1 and itself are called prime numbers.

Such numbers have only two factors.

Examples are: 2, 3, 5, 7 ,9... etc.

Answer:

Prime numbers

Step-by-step explanation:

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

Answer:

D)  12 1/2 miles

Step-by-step explanation:

you can create a proportion for inches over miles equals inches over miles

(3/4 ÷ 15/2) = (5/4 ÷ m)

cross-multiply to get:

3/4m = 75/8

cross-multiply again:

24x = 300

x = 12 1/2

Answer:

A = $560.00

Step-by-step explanation:

I = A - P = $60.00

Formula:

[tex]A = P(1 + rt)[/tex]

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 500(1 + (0.06 × 2)) = 560

A = $560.00

The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

Answer:

The answer is Exponential decay, 25% decrease

Step-by-step explanation:

In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time

Answer:

164.6

Step-by-step explanation:

All degrees of a triangle add up to 180°. angle c and angle e are congruent so you add them to get 15.4. you subtract 15.4 from 180 and get 164.6

Answer:

C

Step-by-step explanation:

This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.

Answer:

A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C

C is your answer.

3/7=0.428571

4/7=0.571428

5/7=0.714285

6/7=0.857142

Step-by-step explanation:

1/7 = 0.142857

2/7=2(1/7)

2/7=2(0.142857)

2/7=0.285714

3/7=1/7+2/7

3/7=0.142857+0.285714

3/7=0.428571

Or

3/7=3(1/7)

3/7=3(0.142857)

3/7=0.428571

4/7=2(2/7)

4/7=2(0.285714)

4/7=0.571428

5/7=5(1/7)

5/7=5(0.142857)

5/7=0.714285

6/7=2(3/7)

6/7=2(0.428571)

6/7=0.857142

Answer:

32 years

Step-by-step explanation:

Given data

Principal= $5

Rate= 5%

FInal amount= $25

Time=???

Applying the compound interest formula for time

t= ln(A/P)/r

t= ln(25/5)/0.05

t= ln(5)/0.05

t= 1.60/0.05

t= 35 years

Hence the time is 32 years

Answer:

6 cans

Step-by-step explanation:

Answer:

4 cans

Step-by-step explanation:

The total area is 2(L * H) + 2(W * H) or

2(20 * 10) + 2(15 * 10)

= 2*200 + 2*150 = 700 total sq ft.

Since one can covers 350, then 700/350 = 2 cans, BUT they want 2 coats so

double it (2*2=4).

Step-by-step explanation:

Dave + 6 friends = 7 friends in total

84 ÷ 7 = 12

Each friend paid $12

Each of them paid $12 for the Meal.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Dave and 6 friends went to dinner.

Total amount of meal= $84

So, each of them paid

= 84/ 7

= 12

Thus, each of them paid $12.

Answer:

2x² + 6x + 15 = 0

Step-by-step explanation:

Given quadratic equation is,

-2x² - 6x = 15

We have to convert this equation in the standard form of the quadratic equation,

ax² + bx + c = 0

(-2x² - 6x) = 15

-2x² - 6x - 15 = 0

2x² + 6x + 15 = 0
