Graph of two linear functions y=2x+7 and y=-x+4 will intersect at (1,5)

What do you means by linear function?

A linear function produces a straight line in the algebraic coordinate plane. It often takes the form of a polynomial function with a maximum degree of 1 or 0.

Calculus and linear algebra are also used to express the linear functions.

The primary distinction can be found in the function notation.

An ordered pair stated in function notation must be understood.

Below is a data table for two distinct linear functions with the identical x values for both functions.

x | y=2x+7 y=-x+4 -3 | 2(-3)+7=-6+7=1| -(-3)+4=3+4=7 -2 | 2(-2)+7=-4+7=3|-(-2)+4=2+4=6 -1 | 2(-1)+7=-2+7=5|-(-1)+4=1+4=5 0 | 2(0)+7=0+7=7 |-(0)+4=0+4=4 1 | 2(1)+7=2+7+9 |-(1)+4=-1+4=3 2 | 2(2)+7=4+7=11|-(2)+4=-2+4=2 3 | 2(3)+7=6+7=13|-(3)+4=-3+4=1

Step-by-step explanation:

The best way to find the slope of the line is first find a point that rests on the line on an exact point. This exact point is (-1,0)

Then, once you find that point, continue to use rise/run to find the slope.

In this case, it goes up one, and over one

So, your slope would be 1/1 or just 1.

(NOTE: IF YOU CONTINUE TO KEEP GOING ONE UP AND ONE OVER, IT WILL STILL GIVE YOU THE SAME SLOPE, BUT YOU WILL HAVE TO DO MORE WORK!!)

7y-20

Answer:

5y - 20

Step-by-step explanation:

Simplify the expression.

 Remove the parenthesis by multiplying each term of (y+ 4) by (-3) and  multiplying each term of (2y - 2) by 4

 -3(y + 4) + 4(2y - 2) = (-3)*y + (-3)*4 + 4*2y - 2*4

                                = -3y - 12 + 8y - 8

Combine like terms (-3y & 8y) and constants (-12 & -8).

three friends ate at a restaurant. they ordered nachos for $19.95 and jalapeno poppers. each friend paid $9.73, not including sales tax or tip, which was one third of the total. determine the cost of the jalapeno poppers. $6.65 $9.24 $18.48 $29.19

Answers

The cost of the jalapeno poppers was $9.24 if each friend paid $9.73.

The cost of the jalapeno poppers can be determined by using multiplication followed by subtraction.

First, we determine the total amount paid by the three friends;

If each friend paid $9.73, then;

Total amount = 9.73 × 3

Total amount = $29.19

Now to find the cost of jalapeno poppers, we subtract the cost of nachos from the total amount paid by the three friends;

cost of jalapeno poppers = total amount - cost of nachos

cost of jalapeno poppers = 29.19 - 19.95

cost of jalapeno poppers = $9.24

Therefore, the cost of jalapeno poppers is calculated to be $9.24.

A water treatment plant needs to maintain the ph of the water in the reservoir at a certain level. To monitor this, they take 2 oz. Of water at 37 locations every hour, measure the ph at each of those locations, and find their average. If the ph level of the reservoir is ok, the results at each location will have varying results, with an average ph of 8. 5 and a standard deviation of 0. 22. If the ph level of the reservoir is ok, what is the probability that the sample average is less than 8. 42?.

Answers

The probability that the sample is less than 8.42 is 0.0029 or 0.29%.

Using the normal distribution and the central limit theorem,

The mean is μ = 8.5

The standard deviation is σ = 0.22 .

A sample of 37 is taken, hence n = 37, s = 0.22/√37 i.e. s = 0.0362

The probability that the sample average is LESS than 8.40 is the p-value of Z when X = 8.4, hence:

Z = X - μ/σ

Z = 8.4 - 8.5/0.0362

Z = 2.76

Z = -2.76 has a p-value 0.0029

0.0029 = 0.29% probability that the sample average is LESS than 8.40.

What is a inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Comparing decimals involves starting with the digits having the highest place value, just like when comparing other whole numbers. We begin the comparison by putting the provided decimal numbers in a place value table. We move on to the digits in the next place to the right if the digits on the biggest place value match. Up till the digits that are different are reached, we continue comparing digits.

−6.809< −6.812

(1) PQRS is a rhombus. Prove that APQT = APST by using all four conditions of congruency. ​

Answers

Four conditions of congruency are: SSS, ASA, SAS, RHS

Using SSS congruency,

Side: PS = PQ (by the rule, all sides of rhombus are equal)

Side: ST = TQ (by the rule, diagonals bisect each other)

Side: PT = PT (common)

Therefore, Area(PQT) = Area(PST) by SSS congruency

Using ASA congruency,

Angle: ∠TPS = ∠TPQ (diagonals bisect the angles)

Side: PS = PQ (by the rule, all sides of rhombus are equal)

Angle: ∠PST = ∠PQT (opposite angles are equal, and diagonals bisect the angles)

Therefore, Area(PQT) = Area(PST) by ASA congruency

Using SAS congruency,

Side: ST = TQ (by the rule, diagonals bisect each other)

Angle: ∠PTS = ∠PTQ (by the rule, diagonals bisect each other at 90°)

Side: PT = PT (common)

Therefore, Area(PQT) = Area(PST) by SAS congruency.

Using RHS congruency,

Right angle: ∠PTS = ∠PTQ (diagonals bisect each other at 90°)

Answers

Answer:

Step-by-step explanation:

Answer:

The exact Population of the city Y in 2010 was 160,000.

Step-by-step explanation:

Given that,

1. In the year 2015, the populations of City X and City Y were equal.

2. City X population is increased by 20% and City Y population is decreased by 10% from 2010 to 2015.

3. Also, the population of City X was 120,000 in 2010

With the given data, calculation goes like this,

The population of City X in 2010 is 120000

Population Increased by 20% till 2015,

                = 120000×120/100

                = 144000

As Population of city Xand Y are same,

Population of city Y in 2015 would be 144000.

Population of Y in 2010 was decreased by 10%,

                = 144000×100/90

                =160000

Therefore, the Population of city Y in 2010 was 160,000.
