Step-by-step explanation:

Answer:

Gradient: -4

y-intercept: [tex]-\frac{9}{2}[/tex]

Step-by-step explanation:

Step 1 - Subtract 8x from both sides to isolate the 2y + 9

[tex]8x + 2y + 9 = 0\\8x + 2y + 9 - 8x = 0 - 8x\\2y + 9 = -8x\\[/tex]

Step 2 - Subtract 9 from both sides to isolate the 2y:

[tex]2y + 9 = -8x\\2y + 9 - 9 = -8x - 9\\2y = -8x - 9[/tex]

Step 3 - Divide both sides of the equation by 2:

[tex]\frac{2y}{2} = \frac{-8x}{2} - \frac{9}{2}\\y = -4x - \frac{9}{2}[/tex]

In this form, y = mx + b, the m value is the gradient with the b value being the y-intercept. This means:

[tex]y = -4x - \frac{9}{2}\\\\m = -4\\b = -\frac{9}{2} \\\\[/tex]

Resulting in the gradient being -4 and the y-intercept being [tex]-\frac{9}{2}[/tex].

Work Shown:

x = number of pounds of strawberries purchased

1.38x = cost of buying those x pounds of strawberries, at $1.38 a pound

1.38x = 241.50

x = (241.50)/(1.38)

x = 175

As a check,

1.38*x = 1.38*175 = 241.50

which confirms the answer

Answer:

a = 16, b = 6, c = - 4, d = - 9

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate.

x = - 3 : y = 1 - 5(- 3) = 1 + 15 = 16 → a

x = - 1 : y = 1 - 5(- 1) = 1 + 5 = 6 → b

x = 1 : y = 1 - 5(1) = 1 - 5 = - 4 → c

x = 2 : y = 1 - 5(2) = 1 - 10 = - 9 → d

Answer:

a=16; b=6, c= -4, d= -9

Step-by-step explanation:

[tex]f(x)=1-5x\\f(-3) = 1-5(-3)=1+15=16\\f(-1) = 6\\f(1)=-4\\f(2)=-9[/tex]

Answer:

Multiply

Step-by-step explanation:

You need to multiply the number by 10 or 100 or 1000 according to the number. but after multiplying it should become a whole digit. And you also need to multiply 10 or 100 or 1000 in the dividend.

Hope this has helped you.

1) Through any two points, there is exactly one line.- postulate

2) A line segment is a part of a line and is bounded by two endpoint. - Definition

3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem

"These are statements that are assumed to be true without proof."

"It is used to give a precise meaning to a new term."

"It is a statement that can be proved to be true by accepted mathematical operations and arguments"

For given question,

We have been given three statements.

We need to classify them as theorem, postulate and definition.

The first statement is 'Through any two points, there is exactly one line.'

We know that this is the fundamental postulate use in Geometry.

The second statement is 'A line segment is a part of a line and is bounded by two endpoint.'

Above statement is the definition of line segment.

The last statement is 'If two lines intersect, then each pair of opposite angles are congruent.'

We can prove above statement by using Euclid's axiom.

So, above statement is a theorem.

Therefore, 1) Through any two points, there is exactly one line.' - postulate

2) A line segment is a part of a line and is bounded by two endpoint. - Definition

3) If two lines intersect, then each pair of opposite angles are congruent. - Theorem

i think its 2.5 because 15/6= 2.5 so 2.5t=h and the equation is kt=h so 2.5 makes the most sense.

Answer:

450 minutes

Step-by-step explanation:

1st plan

18 + 0.13x = y

2nd plan

0.17x = y

x is minute of calls

y is the total price customers must pay

both of them equal as y = y

y = y

18 + 0.13x = 0.17x

18 = 0.17x - 0.13x

18 = 0.04x

x = 18/0.04

x = 450 minutes

Answer: in your graphplot the point of the y-intercept(which in this case is 1, hence the “+1”)

Step-by-step explanation:

Next 5x is the same as -5/+1 which pretty much means you have to go down 5 times and 1 to the right in a repeated motion until you can no longer plot that point.

then you do the opposite of -5x which is -1/+5 which means you have to go up 5 times and 1 to the left in a repeated motion until you can’t

Answer:

subtract 4 from both sides

Step-by-step explanation:

you will then get -3y=27 as your equation then you just divide each side by -3 and your answer will be y = -9

Answer:

Step-by-step explanation:

4 - 3y = 31

Step 1:  Subtract 4 from both sides

        -3y =  31 -4

         -3y = 27

Step 2:  Divide both sides by (-3)

[tex]\dfrac{-3y}{-3}=\dfrac{27}{-3}[/tex]
