We know: the sum of measures of triangle angles is 180°.
Therefore we have the equation

Substitute
:

<h3>Answer: 180 - 7x</h3>
Answer:
see below
Step-by-step explanation:
-2x-5y=30
To find the x intercept, set y =0 and solve for x
-2x-5*0=30
-2x = 30
Divide each side by -2
-2x/-2 = 30/-2
x =-15
To find the y intercept, set x =0 and solve for y
-2*0-5y=30
-5y = 30
Divide each side by -5
-5y/-5 = 30/-5
y = -6
The vertex is (-5, 5) and the parabola opens downward. The vertex form equation is
.. y = -(x +5)^2 +5
Answer: Salid should get $38.75 of change.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Quantity of window trim bought: 35 feet
</em>
- <em>Cost per feet: $1.75
</em>
- <em>Amount paid: $100
</em>
First, we have to calculate the total cost, by multiplying the Quantity of window trim bought (35) by the price per feet (1.75)
35 x 1.75 = $61.75
Finally, to calculate the change that Salid should get, we have to subtract the total cost (61.75) to the amount paid (100)
100-61.75=$38.75
(x+2)^2+(y+5)^2=1
