how many solutions are in y=2x−4−21x+3y=3

Answers

Answer 1

Step-by-step explanation:

there are 2 variables in one equation, and none of the variables can be eliminated through simplification.

-19x + 3y - 4 = 3

-19x + 3y = 7

so, there will be infinitely many solutions.

NEED THESE ASAP: You have an isosceles triangle where the two legs form a 90 degree angle. One of these legs is 2cm. What is the hypotenuse of the triangle? Express your answer using two decimal places only.

Why would you make the size of one of the sides of a right triangle if its other side is 12cm and the hypotenuse is 20cm?​

Answers

Answer:

1) 2.83 cm

2) 16 cm

Step-by-step explanation:

1)

A isosceles right triangle has two 45° angles and a 90° angles. The legs are congruent.

If one leg measures 2 cm, then both legs measure 2 cm.

Then we use the Pythagorean theorem to find the hypotenuse.

a² + b² = c²

(2 cm)² + (2 cm)² = c²

c² = 8 cm²

c = √8 cm

c = 2.83 cm

Answer: 2.83 cm

2)

a² + (12 cm)² = (20 cm)²

a² + 144 cm² = 400 cm²

a² = 256 cm²

a = 16 cm

Answer: 16 cm

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year
of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the
terms of her credit card:
• It has a 15% annual interest rate.
• The interest is compounded monthly
• The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1 + r/n)^nt, where (1 + r/n) represents the growth factor of the interest rate.

Answers

Answer:

P = $300

r = 0.15

n = 12

$544.61  (to the nearest cent)

[tex]P(1+r)^t[/tex]

$524.70  (to the nearest cent)

Step-by-step explanation:

P = principal amount = $300

r = annual interest rate in decimal form = 15% = 15/100 = 0.15

n = number of times interest is compounded per unit t = 12

How much she'll owe in 4 years

P = 300

r = 0.15

n = 12

t = 4

[tex]P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}[/tex]

= $544.61  (to the nearest cent)

Yearly compounding interest rate

[tex]P(1+r)^t[/tex]

How much she'll owe in 4 years at yearly compounding interest

[tex]P(1+r)^t=300(1+0.15)^4[/tex]

= $524.70  (to the nearest cent)

What is the equation of the line that passes through the point (3,−5) and has a slope of 0?

Answers

Slope zero
Y=0x+b
Y=b
Y=-5

Answer:

The answer is y + 5 = 0

Step-by-step explanation:

We know that, the equation of a line passing through point P(a, b) and slope m is given by

(y – b) = m(x – a) ...(1)

Here, The given point is P(3, -5) and slope is m = 0

from (1) we get

[(y – (-5)] = 0(x – 3)

y + 5 = 0 is the required equation of line.

Thus, The answer is y + 5 = 0

What is population density?

The number of people living in a unit area is called population density. It is the ratio of the population of the country and the area of the country.

Countries with the highest populations in the world also have the highest population densities.

This statement is false because the population density depends on the area.

What are ratio and proportion?

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Ingrid mixes 3.6 pounds of almonds with some raisins to make a trail mix.

She divides the trail mix into 12 equal portions.

Each portion weighs 0.7 of a pound.

Then the weight of the 12 trail mixed will be.

0.7 × 12 = 8.4

The weight of the 12 trail mixed is 8.4 pounds. But 3.6 pounds of the almonds. So, the mix Ingrid will be

2^2 = 4

3^2 = 9

This means there are 0...31 so 32 perfect squares less than 1000.

At Trendy Tailor Boutique's annual end-of-season sale, every necktie in the
shop gets marked down. Will purchased 7 neckties during the sale. Each
necktie cost $8 less than its full price. He paid a total of $147.
Which equation can you use to find f, the cost of each necktie at full price?

Answers

By direct calculation, we will see that the full price of each necktie is $29.

How to find the complete price of each necktie?

Let's say that the full price of each necktie is f.

We know that Will each necktie costed $8 less than the full price, so he paid:

(f - $8) for each one.

Knowing that he bought 7 and paid a total of $147, we know that he paid:

$147/7 = $21

Then we need to solve:

(f - $8) = $21

Solving for f, we have:

f = $21 + $8 = $29.

So the full price of each necktie is $29.
