Answer:
Isn't it 18?
Step-by-step explanation:
Because you need to add 4 and 2 then multiply it with 3?
Answer:
The solution is (0, 3)
Step-by-step explanation:
First, reduce 2x + 4y = 12 to x + 2y = 6, for easier calculations.
Next, substitute y - 3 for x in the other equation:
y - 3 + 2y = 6, or
3y = 9
Then y = 3. Since x = y - 3 in general, x = 3 - 3 = 0 when y = 3.
The solution is (0, 3)
Equation of the first circle is (x - 1)² + (y + 2)² = 9 and that of the second circle is x² + (y + 2)² = 9
Step-by-step explanation:
- Step 1: Given the center of the first circle (h,k) = (1,-2) and radius, r = 3
Equation of the circle = (x-h)² + (y-k)² = r²
⇒ (x - 1)² + (y + 2)² = 9
- Step 2: Given the center of the first circle (h,k) = (0,-2) and radius, r = 3
⇒ x² + (y + 2)² = 9
Answer:
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
Step-by-step explanation:
You need to set variables and create system of equations first.
Elsa= e
Deon= d
Carlos = c
e+d+c=107
d=e+5
c=4e
Now you plug in the values into the equation x+y+z=116
e+(e+5)+(4e)=107
6e+5=107
6e=102
e=17
You plug in the value of x into the other equations.
e = 17
d= 17+5=22
c=4*(17)=68
Rearrange so it corresponds with days...
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
the slope is 6-2/2-(-2)=4/4=1
point slope form: y-6=1(x-2)
slope-intercept form: y=x+4
Standard form: -x+y=4 change to x-y=-4
Hope that had helped
Have a nice day :)
