Please help haha imm failing math 5(x−2 2/5)=−5.2

Answers

Answer:

x = 1.36

Step-by-step explanation:

5(x - 2 2/5) = -5.2

5(x - 12/5 ) = - 5.2

(x - 12/5) = -5.2 / 5

x - 12/5 = - 1..04

x = -1.04 + 12/5

x = (- 5.20 +12) /5

x = 6.80 / 5

x = 1.36

you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 )  units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x

(Sorry, its a bit wordy :) )

Step-by-step explanation:

The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)} is a function. What do you notice about the two groups of points? What do you think it means to be a function? plsss help yall i need the answer for a disscussion and this teacher NEVER give anybody an 100% on disscussions so at least get me an 80

Answers

Answer:

I notice that the first group of points contain multiple Y Values for the same X. Notice how 0 could be 1 or 5. The second group has a unique Y for every X. A function is a deterministic system where, given a X, it will map exactly one Y value.

james borrows Php 700000 and promises to pay the principal and interest at 15% compounded monthly. How much must he repay after 7 yrs?

Answers

Answer:

A = $ 1,987,379.10 + 700,000= $2,687,379.10

Step-by-step explanation:

15% = 0.15 rate per tear

A = P (1+r/n)^nt

A = 700,000 (1+0.015/12)^12*7

A = 700,000 (1+0.0125)^84

A = 700,000 ((0.9875)^84

A = 700,000 (2.839113)

James will have to pay PHP 1987379.1 after 7 years.

What is the interest rate?

The percentage that a lender adds to the amount of money lent to them is called an interest rate.

Given that, James borrowed, 700000 at an interest rate of 15% compounded monthly.

The formula for the final amount in compound interest is:

A = P (1 + r/n)ⁿˣ

Where P is the principal amount, n is the number of times of compounding in a year, r is the interest rate, and x is the time in years.

Substitute the values in the formula:

A = 700000(1 + 15%/12)¹²⁽⁷⁾

A = 700000( 1 + 0.15/12)⁸⁴

A = 700000(1.0125)⁸⁴

A = 1987379.1

Hence, James will have to pay PHP 1987379.1 after 7 years.

what is the value of W?

Answers

Solution: According to mid point theorem, the line segment joining the mid-points of any two sides of a triangle, is parallel to the third side and half of it.Here, UQ = QR

So, Q is the mid-point of UR.

Similarly, UT = TS

So, T is the mid-point of US.

So, QT is parallel to RS and half of it.Given, QT = w and RS = w + 37Therefore, QT = 1/2 RS

or, w = 1/2(w + 37)

or, w = w/2 + 37/2

or, w - w/2 = 37/2

or, w/2 = 37/2

or, w = 37/2 × 2

or, w = 37.

Answer:

The value of w is 37.

What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?

Answers

Answer:

y = x + 1

Step-by-step explanation:

The gradient of a line can be defined by the equation:

m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript

For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):

x2 = -7, y2 = -6

Plug these values into the formula above:

m = (y-(-6)) ÷ (x-(-7))

m = (y+6) ÷ (x+7)

At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.

x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:

y = x-7 ---> The gradient (coefficient of x) is 1.

Therefore, the gradient of the other parallel line must also be 1.

This can be substituted into the previous equation to give:

1 = (y+6)÷(x+7)

x+7 = y+6

x+1 = y

Therefore, the answer is y=x+1
