Answer:
-2
Step-by-step explanation:
Given that:
A = (3, 4) ; B = (7, 6)
In triangle ABCD, AB and BC are Perpendicular lines :
Slope AB = Rise / Run = (y2 - y1) / (x2 - x1)
y2 = 6 ; y1 = 4 ; x2 = 7 ; x1 = 3
Slope AB = (6 - 4) / (7 - 3) = 2 / 4 = 1 / 2
To obtain the slope of BC:
RECALL:
product of the slope of 2 Perpendicular lines = - 1
Slope AB * Slope BC = - 1
1 / 2 * slope BC = - 1
Slope BC = - 1 ÷ 1/2
Slope BC = - 1 * 2/1
Slope BC = - 2
HENCE, slope of BC = - 2

Step-by-step explanation:
In a basketball game Elena scored twice as many points as Tyler Tyler scores four points fewer than Noah and Noah scores three points as Mai of Mai scores 5 points how many points did Elena score
Full question:
In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning
Answer and explanation:
We start from known to unknown. We know that Mai scored 5 points and so we work from here.
Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points
Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points
Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points

1. 7=w/14
2.42/n=7
3. 324/18=a
Answer:
w = 98
n = 6
a = 18
Step-by-step explanation:
Question 1)
7 = w/ 14
All you need to do is multiply each side by 14 to find w:
7(14) = W
W = 98
Question 2)
42/n = 7
For this one, first multiply each side by "n":
42 = 7n
and then divide both sides by 7:
N = 6
Question 3)
All you need to do for this question is divide 324 by 18 to find "a":
324/18 = a
a = 18
I hope this helps!

Answer:
3/2
Step-by-step explanation:
The first step is finding two points. (4,6) and (0,0) are two easy points to use.
To find the slope, find the change of y over the change of x.

the path of a toy rocket is modelled by the equation y=-x^2+6x+2, where x is the horizontal distance, in metres, travelled and y is the height, in metres, of the toy rocket above the ground. what is the maximum height of the toy rocket? at what horizontal distance does the maximum height occur?
Answer:
The path of a toy rocket is defined by the relation y=-3x^2+11x+4, where x is the horizontal distance, in meters, traveled and y is the height, in metres, above the ground.
Determine the zeros of the relation.
-3x^2 + 11x + 4 = 0
---
3x^2 - 11x -4 = 0
Factor:
3x^2 - 12x + x - 4 = 0
---
3x(x-4) + x-4 = 0
---
(x-4)(3x+1) = 0
---
x = 4 or x = -1/3
============================
f(x) = -3x^2+11x+4
How far has the rocket traveled horizontally when it lands on the ground?
4 ft.
==================
What is the maximum height of the rocket above the ground, to the nearest hundredth of a meter?
---
max occurs when x = -b/2a = -11/(2*-3) = 11/6
height = f(11/6) = 14.083 ft

LA BASE DE UN RECTANGULO ES 8 M MAYOR QUE LA ALTURA, EL AREA MIDE 65 METROS CUADRADOS ¿CUANTO MIDEN LA BASE Y ALTURA?
Answer:
23 m and 15 m
Step-by-step explanation:
THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?
Let the height of the rectangle is h.
Base = 8+h
Area of the rectangle, A = 65 m²
We need to find the base and height of the rectangle. The area of a rectangle is given by :
A = bh
So,
[tex]65=(8+h)\times h\\\\65=8h+h^2\\\\h^2+8h-65=0\\\\(h-5)(h+13)=0\\\\h=5\ m\ \text{and}\ x=-13\ m[/tex]
Neglecting negative value, h = 15 m
Base = 8+15 = 23 m
So, the base and height of the rectangle is 23 m and 15 m respectively.
Calculate the product using partial products

what is the y from for 5y+4x=-20 NEED HELP ASAP
Answer: y=−4/5x−4
Step-by-step explanation:
5y+4x=−20
Step 1: Add -4x to both sides. 4x+5y+−4x=−20+−4x 5y=−4x−20
Step 2: Divide both sides by 5.
y=−4/5x−4
