Answer:
y=-x-2
Step-by-step explanation:
slope-intercept form is y = mx+b
slope is change in y over change in x, which is -5-(-3)/(3-1) = -1
y = -x+b
plugging in a point, like (1,-3), we have -3 = -1+b. b = -3+1 = -2
y = -x-2
Answer:
Each student should get 7:75 gallons of water
Step-by-step explanation:
Do 62 divided by 8
To make things easier, convert the mixed number 12 1/2 into a fraction.
12 1/2 = 25/2
1/3 x 25/2 = 25/6
Answer:
<em>1+√3</em>
Step-by-step explanation:
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * AC * BD
We need to get AC
AC = AD+DC
Get base AD using SOH CAH TOA
tan 45 = 4/AD
AD = 4/tan45
AD = 4/1
AD = 4
Get DC
tan 30 = 4/DC
DC = 4/tan 30
DC = 4/(1/√3)
DC = 4√3
AC = 4 + 4√3
AC = 4(1+√3)
Get the Area of the triangle
<em>Area = 1/2 * 4 * 4(1+√3)</em>
<em>Area of the triangle = 1+√3</em>
