Answer:
y = x² + 2x + 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 1, 4), thus
y = a(x + 1)² + 4
To find a substitute (0, 5) a point on the graph into the equation
5 = a(0 + 1)² + 4
5 = a + 4 ( subtract 4 from both sides )
a = 1, thus
y = (x + 1)² + 4 ← expand and simplify
= x² + 2x + 1 + 4
= x² + 2x + 5
Lucy would save $114.
Step 1: Multiply 6.175 x 30 = 185.25
Step 2: Divide 370,000/185.25 = 1,997
Step 3: Repeat Steps 1&2 but with (6.55 x 30) and divide 370,000/196.5 = 1,883.
Step 4: Subtract 1,997 - 1,883 = 114
Step 5: She will save $114 with points versus without.
Answer: 24 cm
Step-by-step explanation:
Mrs Lopez cut 46cm of yarn.
Miss Hamilton then cut 22cm less than what Mrs Lopez had cut.
Mrs. Hamilton must have therefore cut:
This is a case of subtraction:
= 46 - 22
= 24 cm
Answer:
6.569
Step-by-step explanation:
Difference is subtraction.
10.22-3.651=6.569
Answer:
Each question worth 5.
Step-by-step explanation:
Each question worth 5 Point because
5 x 20 = 100
Hence, 20 question each question worth 5 point.
If You get a 45% then you miss 11 question and only get 9 question correct..
9/20 x 100 = 45.
