graph a line x + y = -1

Answer: 5x+7y=500

Step-by-step explanation:

Answer:

d. {(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}; Domain: {-2, -1, 0, 1, 2}; Range: {1, 2, 5}

Step-by-step explanation:

Part A:

Domain = the set of all x-values plotted on the x-axis = {-2, -1, 0, 1, 2}

Range = the set of all possible y-values on the y-axis that corresponds with the x-values = {1, 2, 5}

Part B:

The set of coordinates that describes the function on the graph are:

When x = -2, y = 5 => (-2, 5)

When x = -1, y = 2 => (-1, 2)

When x = 0, y = 1 => (0, 1)

When x = 1, y = 2 => (1, 2)

When x = 2, y = 5 => (2, 5)

The set of coordinates is:

{(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}

Answer:

Step-by-step explanation:

1). [tex]-\frac{5}{12}[/tex] x = 0 ⇒ x = 0

2). 5,4 ( x + 6,3 ) = 0 ⇒ x + 6,3 = 0 ⇒ x = - 6,3

3). ( x - 3 )( x + 4 ) = 0 ⇒ x - 3 = 0 или x + 4 = 0 ⇒ x = 3 или x = - 4

4). 23,5 | x | = 0 ⇒ | x | = 0 ⇒ x = 0

======================================================

Explanation:

Convert the x = 82 to a corresponding z score.

z = (x-mu)/sigma

z = (82 - 89)/7

z = -7/7

z = -1

Using the empirical rule (see chart below), roughly 68% of the distribution is within 1 standard deviation of the mean.

This leaves 1 - 0.68 = 0.32 = 32% of the distribution in both tails, and (32%)/2 = 16% of the area is in one tail, which converts to 0.16

About 16% of the normally distributed population is below z = -1.

So we can say [tex]P(x \le 82) = P(z \le -1) \approx 0.16[/tex]

z value:-

[tex]\\ \rm\Rrightarrow \dfrac{x-\overline{x}}{\sum}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{82-89}{7}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{-7}{7}[/tex]

[tex]\\ \rm\Rrightarrow -1[/tex]

As per z value chart

Option C is correct

The equation of any straight line can be written as in slope intercept form as -

[tex]\green{ \underline { \boxed{ \sf{y=mx+c}}}}[/tex]

where,

Given equation:-

[tex]\begin{gathered}\\\implies\quad \sf 5x+y = 10 \\\end{gathered} [/tex]

Arranging it in slope intercept form by transposing 5x to RHS

[tex]\begin{gathered}\\\implies\quad \sf y = 10 -5x \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf y = -5x +10\\\end{gathered} [/tex]

[tex]\leadsto[/tex]Comparing the equation y = -5x +10 with the standard form of the equation, we get -

[tex]\quad \bull\: \sf m= -5[/tex]

[tex]\quad \bull \: \sf c= 10[/tex]

Thus , 5 is our required answer.

Answer:

[tex]\displaystyle y = -5x + 10[/tex]

Step-by-step explanation:

5x + y = 10

- 5x - 5x

Answer:

y-5 = 3/4(x-6)

Step-by-step explanation:

point slope formula is y - y₁ = m(x - x₁) where m=slope and (x₁ ,y₁) is a point on the line.

First find the slope.  From the graph we have pts A and B.

A= (-2,-1) and B is (6,5)

m= y-y₁/x-x₁  m= (5-(-1)/(6-(-2))

m= 6/8 = 3/4

Using point B for x₁ and y₁

y-5 = 3/4(x-6)

Answer:

a n= - 3a_{n-1}a n−1 with a₁ = - 0.3

Step-by-step explanation:

The recursive formula for a geometric sequence is of the form

a_{n}a

n = ra_{n-1}a

n−1

where r is the common ratio

r = \frac{a_{2} }{a_{1} }

a

Answer:

$0.41 per apple.

Step-by-step explanation:

A dozen apples stand for 12. If we want to find the rate, we must divide.

$4.92 ÷ 12 = 0.41.

The rate for a dozen apples that cost $4.92 is $0.41 per apple.

Answer:

$0.41 per apple

Step-by-step explanation:

right angled triangle because it has clearly shown the sign of 90 degree

Answer:

First piece = 30m , 2nd is 120 m and third piece is 240 m long.

Step-by-step explanation:

Let the length of the first piece be x m.

Then the length of the second piece = 4x m.

The third piece = 2 * 4x = 8x m.

So x + 4x + 8x = 390

13x = 390

x = 30 m

So 2nd piece = 4*30 and third is 8*30  m.

Hello!

This is an equilateral triangle. In this triangle, the angles are congruent, respectively, the sides. Here, the mediator corresponds to the bisector, the median. So this line will form two  right triangles.

Th 30-60-90

I used the 30-60-90 theorem, which says that the opposing the angle of 30 degrees has the length equal to half the hypotenuse.

Th Pitagora's

Which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Good luck:)
