The Vertex of the parabola is V=(-5,-2)=(h,k)→h=-5, k=-2
This is a vertical parabola, then its equation has the form:
y=a(x-h)^2+k
Relacing h=-5 and k=-2
y=a(x-(-5))^2+(-2)
y=a(x+5)^2-2

When the x-value is -4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation:
a=?
x=-4, y=2→2=a(-4+5)^2-2
2=a(1)^2-2
2=a(1)-2
2=a-2
2+2=a-2+2
4=a
a=4

Answer: The coefficient of the squared expression in the parabola's equation is 4

Answer: Option B. 4

A sailboat's Saul has three sides that are all the same length. Each side measures x - 10 units. The sail's perimeter is 63 unit
ruslelena [56]

Answer:

The value of 'x' is 31 unit

Step-by-step explanation:

Given:

Measure of each side = x-10\ units

Perimeter of sails  = 63 units.

We need to find the value of x.

Solution:

Now we can see that from given data.

A sailboat's Saul has three sides.

Now assuming it to be triangle we get;

"Perimeter of triangle is equal to sum of all side."

So we can say that;

x-10+x-10+x-10 =63\\\\3x-30=63

Now adding both side by 30 we get;

3x-30+30=63+30\\\\3x=93

Now dividing both side by 3 we get;

\frac{3x}{3}=\frac{93}{3}\\\\x=31 \ units

Hence the value of 'x' is 31 units.

Well according to the slope intercept equation.

Y = mx +/- b

The slope is the value m
The y intercept is b

To graph the function, one sure way to do it is simply make a table of values picking any x values that fall within the graph space, and finding out the resulting y values and using the points to graph.

For instance for the first graph, if x = 0, y = 5, that is one possible point. Keep on choosing x values to graph.

The difference between sixteen, and the product of seven and two
Monica [59]

Answer:

2

Step-by-step explanation:

If this product was written as an equation, it would look like this:

16 - 7 * 2

PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.

7 * 2 = 14

Now, the equation looks like:

16 - 14

All we need to do now is subtract 14 from 16.

16 - 14 = 2

So, the final answer is 2.
