The vertex is at (-3, 4)
This can be found by looking at the basic form of vertex form:
y = (x - h)^2 + k
In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = 4. This means the vertex is at (-3, 4).
The y-intercept is at 13. To find this we must first square the parenthesis and get the equation into standard form.
y = (x + 3)^2 + 4
y = x^2 + 6x + 9 + 4
y = x^2 + 6x + 13
Now we know that the y-intercept is equal to the constant, which is the last number in the equation.

Answer:
C. 50 degrees.
Step-by-step explanation:
The angles of the triangle add up to 180. So the remaining angle is 50.
Answer:
The mechanic will need to finish in 4 hours.
Step-by-step explanation:
100+40=140
40+40=80
40+40=80
40
140 +80 + 80+ 40= 340
Total number of yards of ribbon available = 25 yards.
Number of yards of fabric available = 30 yards.
Number of yards of ribbon a child need = 1.75 yards
Number of yards of fabric a child need = 2.8 yards.
<em>Total number of children participate in the activity for 25 yards of ribbon = 25/1.75 = 14.28 approximately 15 children.</em>
<em>Total number of children participate in the activity for 30 yards of fabric = 30/2.8 = 10.7 approximately 11 children.</em>
<h3>Therefore, maximum 11 children can participate in the activity because each child required both 1.75 yards of ribbon and 2.8 yards of fabric .</h3>
