Answer:
y + 1 = 7(x + 2)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 7
Point (-2, -1)
<u>Step 2: Write Equation</u>
<em>Substitute in variables into general form.</em>
y + 1 = 7(x + 2)
Volume of prism = 1/2 a c h
= 1/2 × 7 × 9 × 15 = 472.5
Therefore, the vorrect answer is A. 472.5 ft
Answer:
233.53 s
Step-by-step explanation:
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.
Answer:
Step-by-step explanation:
y=mx+c
where m is the gradient and c is the y-intercept of the line
Let's find the gradient of the line first.
Using the above formula,
Subst. the gradient into m:
Now, find the value of c by substituting a coordinate into the above equation.
when x=-1, y=3,
Therefore the equation of the line is
