The equation for the quadratic graphed as x-intercepts: (-3,0) and (-1,0); y-intercept: (0,-2) can be written as y = -1/2 (x+3)(x+1)

An equation of the second degree, or one with at least one squared term, is a quadratic equation. The equation in standard form is written as ax2 + bx + c = 0, where a, b, and c are numerical coefficients that are constants, and x is an unknown variable.

The initial constant, “a,” cannot be 0, and this is an unbreakable rule.

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The slope is the ratio of the y-to-x change.

Thereafter draw a sloping triangle connecting the two spots you find on the line.

If the x intercepts are -3 and -1, then the factored form is y = a(x + 3)(x + 1). In order to find "a", we plug in the data point (x, y) of (0, -2) so:

-2 = a(0+3)(0+1)

-2 = 4a

a = -1/2

So the equation can be written as y = -1/2 (x+3)(x+1)

Answer:

x = 8

y = 8

Step-by-step explanation:

The two equations are:

x + y = 16    (1)

x = y           (2)

Since x = y substitute for y in terms of x in (1):
x + x = 16

2x = 16

2x/2 = 16/2

x = 8

y = 8

Step-by-step explanation:

Have a good day :)

The system of inequalities is:

y < -4*x + 1

y ≥ (1/2)*x + 1

Here we can see two lines, one dashed that passes through (0, 1) and (-1, 5), then the slope is:

s = (5 - 1)/(-1 - 0) = -4

And the y-intercept is 1, then the inequality is:

y < -4*x + 1

The other line is solid, and the shaded region is above the line.

This line passes through (0, -1) and (2, 0), then the slope is:

s = (0  + 1)/(2 - 0) = 1/2

So the inequality is:

y ≥ (1/2)*x + 1

Yes, This situation represent a function.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The cost of each car = $40

The cost of each person = $8.50

Let the number of car = x

The number of persons in a car = z

Then, Total cost of car = $40x

Total cost of persons in car = $8.50z

So, Total cost (y) = $40x + $8.50z

Thus, The function for this situation is;

y = $40x $8.50z

Clearly, This is a linear function with three variable.

a. Solving for 'd' as the subject of formula gives d = P/64

b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet

A function can be defined as an expression, law or rule that shows the relationship between two variables.

These variables are namely;

Given the function as;

P = 64d

Where;

Now, let's make the variable 'd' the subject of formula

Divide both sides of the equation with the coefficient of the variable 'd' which is 64. This is done so that the variable stands alone.

We have;

P/64 = 64d/64

d = P/ 64

If the pressure, P equals  672 pounds per square foot

Substitute the value of the variable into the formula, we have;

d = P/64

Then,

d = 672/64

Find the quotient

d = 10. 5 feet.

Since, Serving of 1 pancakes takes 2/3 cups of milk

Hence, serving of 24 pancakes takes (2/3)*24

                                                    =48/3

                                                   =16

So that; 16 cups of milk are required for serving of 24 pancakes.

Answer:

16 cups of milk

Step-by-step explanation:

Make a proportion

[tex]\frac{serrvings}{cups of milk}[/tex] = [tex]\frac{servings }{cups of milk}[/tex]

[tex]\frac{1}{\frac{2}{3} }[/tex] = [tex]\frac{24}{x}[/tex]  cross multiply and solve

1x = [tex]\frac{2}{3}[/tex][tex](\frac{24}{1})[/tex]       1x is the same a x.  24 is the same as [tex]\frac{24}{1}[/tex]

b) The rules are given as follows:

The transformations used in this problem are as follows:

For this problem, the orientation of the triangle changed, with the C at the bottom of the triangle being transformed into C'' at the top of the transformed triangle, hence the figure was reflected over the x-axis, and the rule is:

(x,y) -> (x, -y).

After the reflection, the coordinates of C' are given as follows:

C' (-4, -1).

The final coordinates of C'' are given as follows:

By graphing both equations and finding where the graphs intercept, we can see that the solution for the system is x = 3.

Here we have the functions:

f(x) = -2x +4

g(x) = 2x - 8

We want to find the value of x such that:

f(x) = g(x).

If we graph the two functions, we just need to identify the x-value of the point where the functions intercept.

The graph can be seen in the image below.

There we can see that the graphs intercept at (3, -2), meaning that the solution of:

f(x) = g(x) is x = 3.

After 10 years, the money dis she earn is $800 with the interest of 6%.

Interest:

Interest is the amount for a particular principal amount of money at some rate of interest.

Given,

Jackie deposited $500 in an account for 10 years at 6% interest.

Here we need to find the money did she earned.

We know that, the interest for the amount is 6%.

So, the amount after 10 years is,

=> 500 x (6/100) x 10

=> 30 x 10

=> 300

Therefore, the interest amount is 300.

So, the total amount she will receive after 10 years is,

=> 500 + 300

The required rational number is 7/11.

let the denominator be x.      

and since we are given that the numerator of a rational number is 4 less than its denominator, the numerator will be x-4.

working on the given condition, i.e. If I is added to both its numerator and denominator, it becomes 2/3

(x-4+1)/(x+1) = 2/3

further solving it by cross multiplication we get,

3(x-4+1)=2(x+1)

=> 3(x-3)=2x+2

=> 3x-9=2x+2

=> 3x-2x=9+2

=> x=11

=> x= 11 (denominator)

we know the numerator is 4 less than the denominator i.e.

11-4=7

thus the required fraction will be 7/11.

When there are two middle values, the median is the mean of these two values:

The provided translated function, f(x), shifts left by two units on the horizontal axis.

One type of transformation is translation. Both the scaling calculation and the compression calculation are performed using it. This approach wouldn't change the object's form or shape.

The given graph equation for the translation, as per the query, is g(x) = (x + 2)²

The translation of the given quadratic function is: y = g(x) = (x + 2)²

Consequently, the parent function is written as y = g(x) = x2.

Additionally, the vertex should be known when graphing the translated function:

a(x - h)2 + k = y = g(x);

where the parent function is (0, 0) and the vertex values are (h, k).

(h, k) = is the vertex for the function that is provided (-2, 0)

This information causes the translation function to move the graph two units to the left.

Horizontal translation is the name given to the translation.

As a result, the given function, f(x), shifts horizontally, or left, by 2 units.
