Help easy math problem!!!!!!’

Answer:

y=4x-9

Step-by-step explanation:

The equation of a line is typically written in slope-intercept form, which is y=mx+b. Here's what the variables mean:

y=the y-coordinate

m=the slope

x=the x-coordinate

b=the y-intercept (the point on the line that intercepts the y-axis)

The only values that we have to calculate to find the equation are the slope of the line and the y-intercept. Let's start off by finding the slope.

To find the slope of a line, we would need to find 2 points that fall on the line, [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] and plug them into the expression [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use the points (1, -5) and (3, 3).

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{3-(-5)}{3-1}[/tex]

[tex]=\frac{3+5}{3-1}\\= \frac{8}{2}\\= 4[/tex]

Therefore, the slope of the line is 4.

To find the y-intercept, all we need to do is look at which point the line crosses the y-axis, and that point is -9.

Finally, we plug the slope and the y-axis into the equation y=mx+b as m and b.

y=mx+b

y=4x-9

According to the given statement ,

a debt to double at 42% p.a. compound interest will take approx 2 years.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

Compound interest is calculated on the initial principal of a deposit or loan, which also takes into account all of the accumulated interest from prior periods.

The yearly interest rate is raised to the number of compound periods minus one, and the starting principal amount is multiplied by both of these factors.

According to the given data,

Let principal = P

Time = t

Rate == 42%

Amount = A

Given Condition is A = 2P

=> P[1+ r/100]ⁿ =  2P

=> P [1 + 42/100 ]ⁿ = 2P

=> (1.42)ⁿ=2

n= log₁.₄₂ 2 =0.301/0.152

n=1.980≅2

Hence , the time it take for a debt to double at 42% p.a. compound interest is approx 2 years.

Answer:

(3.2 × 10²) times as large

Step-by-step explanation:

First, set up an equation:

(8 × 10³) ÷ (4 × 10²)

Using the laws of exponents, we know that when two exponents with the same base are being divided by each other, the exponents subtract from each other:

(8 × 4) × (10³⁻²) = (32 × 10¹)

Move the decimal one space to the left, which increases the exponent by 1:

(3.2 × 10²)

Answer: Simplified Equation (10x-10)

Answer if 3=x is 20

Step-by-step explanation:

the original side lengths are 3x and (2x-5) so multiply both those by 2.

Now you have 6x and 4x-10.

Now combine those and you have 10x-10.

Then plug in 3 for x

Answer:

20% or .20

Step-by-step explanation:

There are a total of 10 cards in the sample.

Of these 10 cards there are 2 of them with the number 8 on them.

To find the probability, you divide the part (2) over the whole (10)

2/10 = .20

Then you can multiply by 100 to find the percent

(.20)(100) = 20%

Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.

Probability of sum greater than 5 event is reduces to 13/18 .

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

probability of getting number whose sum is divisible by 2 and 3 both is 6/36 which reduces to 1/6 .

The sample space of rolling two dice has 36 possible outcomes.  Remember that the "sample space" is a set which contains all possible outcomes.   (1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(1,2)(2,2)(3,2)(4,2)(5,2)(6,2)(1,3)(2,3)(3,3)(4,3)(5,3)(6,3)(1,4)(2,4)(3,4)(4,4)(5,4)(6,4)(1,5)(2,5)(3,5)(4,5)(5,5)(6,5)(1,6)(2,6)(3,6)(4,6)(5,6)(6,6)

The probability of the sum is greater than 5 event is 26/36 which reduces to 13/18 .And the probability of getting number whose sum is divisible by 2 and 3 both is 6/36.
