Answer:
y = –1 + 3x
Step-by-step explanation:
To know which option is correct, we shall use the equation given in each option to see which will validate the table. This is illustrated below:
Option 1
y = –1x + 3
x = –2
y = –1(–2) + 3
y = 2 + 3
y = 5
This did not give the required value of y (i.e –7) in the table.
Option 2
y = 1 + 3x
x = –2
y = 1 + 3(–2)
y = 1 – 6
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 3
y = –3 + 1x
x = –2
y = –3 + 1(–2)
y = –3 – 2
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 4
y = –1 + 3x
x = –2
y = –1 + 3(–2)
y = –1 – 6
y = –7
This gives the required value of y (i.e –7) in the table.
Thus, the equation that matches the table is:
y = –1 + 3x
Answer
Find out the how high up the wall does the ladder reach .
To proof
let us assume that the height of the wall be x .
As given
A 25-foot long ladder is propped against a wall at an angle of 18° .
as shown in the diagram given below
By using the trignometric identity
![cos\theta = \frac{Base}{Hypotenuse}](https://tex.z-dn.net/?f=cos%5Ctheta%20%3D%20%5Cfrac%7BBase%7D%7BHypotenuse%7D)
now
Base = wall height = x
Hypotenuse = 25 foot
Put in the trignometric identity
![cos18^{\circ} = \frac{x}{25}](https://tex.z-dn.net/?f=cos18%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7Bx%7D%7B25%7D)
![cos18^{\circ} = \bar{0.9510565162}](https://tex.z-dn.net/?f=cos18%5E%7B%5Ccirc%7D%20%3D%20%5Cbar%7B0.9510565162%7D)
x = 23.8 foot ( approx)
Therefore the height of the ladder be 23.8 foot ( approx) .
Answer:
The Answer would be No
Step-by-step explanation:
Hope im correct.
I did this when i was in middle school
Slope intercept is basically solve for y
y=mx+b
m=slope
b=yintercept
-3x-10y=7
add 3x to both sides
-10y=3x+7
divide both sides by -10
y=-3/10x-7/10
slope is -3/10
yintercept is -7/10 or at point (0,-7/10)
Answer: Branliest plz
ok so for the numbers from 0-150 is one bar, 150-300 is another bar, 300-450 is another bar, and finally 450-600 is the last bar. You put the numbers that go in each different bar i n their seperate bar.
