38-15= 23. I’m guessing this is what you meant. If not please correct me.

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the gi

Marrrta [24]

y = x - 2.....the slope here is 1. A parallel line will have the same slope

y = mx + b
slope(m) = 1
(2,-2)...x = 2 and y = -2
now we sub and find b, the y int
-2 = 1(2) + b
-2 = 2 + b
-2 - 2 = b
-4 = b

so ur parallel line is : y = x - 4

Hey can you help me fast!!!

kotykmax [81]

Answer:

12 ft²

Step-by-step explanation:

the rectangular hole area:

l • w = A

3 • 2 = 6 ft

the triangular hole area:

(b • h) / 2 = A

(4 • 3) / 2 = 6 ft

6 ft + 6 ft = 12 ft²

Someone please help! ATTACHMENT (just the circled one)

Elza [17]

4 (3x+9)-3(5y+7) =11

distribute

12x +36 -15y -21 =11

12x -15y +15 =11

subtract 15 from each side

12x -15y =-4

subtract 12x from each side

-15y= - 12x-4

divide by -15

y = -12/-15 x -4/-15

y = 4/5 x + 4/15

slope = 4/5

y intercept = 4/15

Sorting Quadratic Function Discriminants

nataly862011 [7]

The number of zeros of the quadratic functions, considering their discriminant, is given as follows:

discriminant = 0: 1 Real number solution.

discriminant = -36: 0 Real number solutions.

discriminant = 3: 2 Real number solutions.

discriminant = 2: 2 Real number solutions.

discriminant = 100: 2 Real number solutions.

discriminant = -4: 0 Real number solutions.

<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>

A quadratic equation is modeled by:

$y = ax^2 + bx + c$

The discriminant is:

$\Delta = b^2 - 4ac$

The solutions are as follows:

If $\mathbf{\Delta > 0}$ , it has 2 real solutions.

If $\mathbf{\Delta = 0}$ , it has 1 real solutions.

If $\mathbf{\Delta < 0}$ , it has 0 real solutions.

Hence, for the given values of the discriminant, we have that:

discriminant = 0: 1 Real number solution.

discriminant = -36: 0 Real number solutions.

discriminant = 3: 2 Real number solutions.

discriminant = 2: 2 Real number solutions.

discriminant = 100: 2 Real number solutions.

discriminant = -4: 0 Real number solutions.
