What is the y-intercept of the graph?

Answer:

a

Step-by-step explanation:

supplmentay angles are either of two angles whose sum is 180°

option b is two right angles (90 degree on both) add them together you get 180.

option c is 60 degrees and 120 degrees add them together to get 180 degrees.

option d is 155 degrees and add 25 degrees you get 180.

so the answer is a, because 30 degrees and add the other 30 degrees together you only get 60

The correct answer is A, because 30 degrees and add the other 30 degrees together you only get 60.

The supplementary angles are defined as the angles whose sum is equal to 180°.

Supplementary angles are either of two angles whose sum is 180°

Option b is two right angles (90 degrees on both) add them together you get 180.

Option c is 60 degrees and 120 degrees add them together to get 180 degrees.

Option d is 155 degrees and add 25 degrees you get 180.

Therefore, the answer is A, because 30 degrees and adding the other 30 degrees together you only get 60.

Answer:

[tex]p =4[/tex]

Step-by-step explanation:

Given

Variation: Inversely

[tex]p = 12[/tex] when [tex]q = 45[/tex]

Required

Determine p when [tex]q = 135[/tex]

First, we need to determine the relationship between p and q

Since, it is an inverse variation.

The relationship is:

[tex]p\ \alpha\ \frac{1}{q}[/tex]

Convert to an equation

[tex]p= k *\frac{1}{q}[/tex]

[tex]p= \frac{k}{q}[/tex]

Where k = constant of variation

Make k the subject

[tex]k = p * q[/tex]

When [tex]p = 12[/tex] and [tex]q = 45[/tex]

[tex]k = 12 * 45[/tex]

[tex]k = 540[/tex]

To solve for p when q = 135

Substitute 135 for q and 540 for k in [tex]p= \frac{k}{q}[/tex]

[tex]p = \frac{540}{135}[/tex]

[tex]p =4[/tex]

2/3 = 6/9

Step-by-step explanation:

2 x 3 = 6 so then you have to multiply 3 with 3 which is 9. (because the numerator and denominator should be multiplied by the same number.)

So thats why 2/3 = 6/9 is correct.

Answer:

6 weeks

Step-by-step explanation:

From the question:

Let us represent the number of weeks as x

Andre and Alina are each saving money.

For Andre:

Andre starts with $100 in a savings account and adds five dollars per week

$100 + $5 × x

= 100 + 5x

For Elena

Elena starts with $10 in her savings account and add $20 each week

$10 + $20 ×x

= 10 + 20x

The next step is to equate both algebraic expression for Andre and Elena together

Hence:

100 + 5x = 10 + 20x

Collect like terms

100 - 10 = 20x - 5x

90 = 15x

x = 90/15

x = 6 weeks

Hence, after 6 weeks Andre and Elena would have the same amount of money in their savings account.

Answer:

I believe the answer is 6

Step-by-step explanation:

f(x) = 3x - 15 -- plug 7 into x (that's how many candy bars he's buying)

f(x) = 3(7) - 15 -- solve the equation (just know that 3(7) is the total, and 15 is the amount of money on his gift card.)

f(x) = 21 - 15

f(x) = 6 -- your answer

Answer:

Step-by-step explanation:

From the table you have points (-1, 3) and (2, 9)

general equation

y-y1 = m (x-x1)

the slope m= (y2-y1) / (x2-x1) = 9-3/ 2+1 = 6/3 =2

so the equation shhould be

y+1=2(x-3)

Answer:

78°

Step-by-step explanation:

42+60=102

180-102=78

Answer:

Step-by-step explanation:

first find the final interior angle since we need it to find the exterior

60 + 42 = 102

180 - 102 = 78 degrees

then we just have to do 180 - 78 bc we have a straight line and straight lines are always 180 degrees

180 - 78 = 102 degrees

x = 102

you honestly could just take the 2 values you already know and add them and use that lol

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the square feet of the house be represented as x

Let the number of houses be represented as y

Let the first point be P ( 1400 , 105)

Let the second point be Q ( 1500 , 183 )

Now , the slope of the equation is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope m = ( 183 - 105 ) / 1500 - 1400

Slope m = 78 / 100

Slope m = 0.78

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 1400 = 0.78 ( x - 105 )

On simplifying the equation , we get

y - 1400 = 0.78x - 81.9

Adding 1400 on both sides of the equation , we get

y = 0.78x + 1318.1

Therefore , the value of y is 0.78x + 1318.1

Hence , the equation of line is 0.78x + 1318.1 and the price is $ 176,000
