Answer:
the slope is 6
Step-by-step explanation:
Answer:
Equation: y = 3x + 9
Step-by-step explanation:
To find equation:
Take two coordinates: ( 1 , 12 ) , ( 2 , 15 )
Secondly find slope: ( y2 - y1 ) / (x2 - x1 )
Using the formula: ( 15 - 12 ) / ( 2 - 1 )
: 3 ............this is our slope, m
Using formula to find equation: y - y1 = m ( x - x1 )
: y - 12 = 3 ( x - 1 )
: y = 3x - 3 + 12
: y = 3x + 9 .....our final answer.
The equation in slope intercept form is y = 3x + 9

Haydn made a scale model of a building. The actual height of the building is 75 feet. Haydn's model used a scale in which 1.5 inch represented 30 feet. what is the height in inches of haydn's model ?
Answer:
3.75
Step-by-step explanation:
1.5 equals 30 ft so x2 equals 60 then 15 is half of 20 so half of 1.5 in is .75 so 3 plus .75

Find the value of X
Answer:
x = 155°
Step-by-step explanation:
most left upper angle = 180° - 35° - 90° = 55°
inner middle top angle = 180° - 60° - 55° = 65°
inner middle has right angle, that is 90°
inner middle bottom angle is then, 180 - 90° - 65° = 25°
then as x lies on a straight line with 25°
x + 25° = 180°
x = 180° - 25°
x = 155°
The value of x is 155° .
Sum of all the angles on a line is 180°.
Sum of all the interior angles of a triangle is 180°.

Youlanda bought a new laptop for $459 and paid 7.5% in sales tax. How much did Youlanda pay in sales tax?
Good evening!
In this question, we were asked to solve for the sales tax of the laptop that Youlanda bought.
We were given:
- Cost of laptop: $459
- Sales Tax: 7.5%
In order to find the amount Youlanda paid for the sales tax, we would multiply the cost of the laptop ($459) by the sales tax (0.075):
Calculate:
459 × 0.075 = 34.425
Your answer would be: $34.425
What is the equation of the nine that passes through
5,1)
and has a slope of 6/5
Answer:
y 6/5x-2
Step-by-step explanation
Answer:
y = [tex]\frac{6}{5}[/tex] x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{6}{5}[/tex] , then
y = [tex]\frac{6}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, 1 ) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = [tex]\frac{6}{5}[/tex] x - 5 ← equation of line

x = approximately 7.07
Answer:
Exact: SQRT 50
Approx: 7.07
Step-by-step explanation:
you take both of the 5s and square them.
So 5*5=25 and 5*5 is 25. Since the right angle is opposite the side you are trying to find you add those together to get 50. Then you take the SQRT of 50 because you are trying to solve for x via the pythagorean theorem.
So the exact is SQRT 50
and the approx is 7.07
