The solutions to a certain quadratic equation are x= -4 and X = 3. Write the equation in standard form below.
[blank] +x [blank] [blank] = 0
Answers
Answer:
x² + x - 12 = 0
Step-by-step explanation:
If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0

The vertex C has coordinates:
x = - 4, y = 2If the triangle reflected over the y-axis, the y-coordinates of C and C' will be same but the x-coordinate will change to opposite.
So the vertex C' will have coordinates:

Use intercepts to graph the linear equation 4x+6y=12 .
Answers
Answer:
The Y Intercept is -2 and the slope is 4/6.
Step-by-step explanation:
First, you need to convert that equation into y = mx + b. To do that you need to bring the 6x over on the other side first. 6y = 4x - 12 is what you get.
Then you need to get rid of the 6, you divide it into the 4 and 12 to do that.
You get y = 4/6x - 2.
Your slope is 4 rise and 6 run.
Your Y-intercept is negative 2.
Answer:
First, put it into a graphing form:
4x + 6y = 12
6y = -4x + 12
y = -2/3 + 2
(I would graph this but it`s not letting me attach an image. I`ve laid out the steps below)
- Make a point at (0,2). It`s two units above the origin. This is your y-intercept.
- Move the dot two units down, and three units right. It should end up on the point mentioned in the next step
- Make another point at (3, 0). It`s three units to the right of the origin. This is your x-intercept.
- Continue moving two down , three right until that side of the graph is done.
- Go back to the y-intercept and move two units up, and three units left, until the line reaches the edge.
- Once you have the dots down, connect them with a ruler.
The easier way to do this is by just taking two points, and going all the way across the graph, but it`s not always accurate.
y-intercept = (0,2)
x-intercept = (3,0)
Hope this helps!

[tex]\\ \tt\hookrightarrow h=\dfrac{50}{0.73}[/tex]
[tex]\\ \tt\hookrightarrow h=68.4ft[/tex]
Answer:
sine
sin = o/h
Step-by-step explanation:
The ladder leaning against the building has created a right triangle.
A right triangle is made up of 2 legs (at 90° to each other) and a hypotenuse (longest side).
Trig ratios help us calculate side lengths and interior angles of right triangles:
sin(x) = O/Hcos(x) = A/Htan(x) = O/Awhere x is the angle, O = the side opposite to the angle, A = the side adjacent to the angle, H = hypotenuse
From inspection of the diagram, we need to find the hypotenuse (H) and we have been given the angle (x) and the side opposite to the angle (O):
Therefore, we can use the trig ratio sin(x) = O/H to determine H:
⇒ sin(47) =50/H
⇒ H = 50/sin(47)
⇒ H = 68.36637305... = 68 ft (nearest foot)

Find five consecutive odd integers if the sum of the first three integers is 7 more than the sum of the last two.
Answers
Answer: 15, 17, 19, 21, 23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23
The first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Let x be the first odd integer, then the next four odd integers would be x+2, x+4, x+6, and x+8.
According to the problem, the sum of the first three integers is 7 more than the sum of the last two, which can be expressed mathematically as:
x + (x+2) + (x+4) = (x+6) + (x+8) + 7
Simplifying the equation, we get:
3x + 6 = 2x + 21
Subtracting 2x and 6 from both sides, we get:
x = 15
Therefore, the first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23
