Solve: x²+5x-6 = 0
Answer please
Given that:
x² + 5x - 6 = 0
Here we see that,
→ Product of coefficient of x² and constant term = 1 × 6 = 6
→Difference of the constant term and the coefficient of x² = 6 - 1 = 5
Now the given equation can be written as,
⇛x² + 6x - 1x - 6 = 0
(Here we simply applied the correc sign and splitted the middle term in two terms)
Now let's take the common terms
⇛x(x + 6) - 1(x + 6) = 0
On grouping we get,
⇛(x - 1)(x + 6) = 0
Here either (x - 1) = 0 or (x + 6) = 0 since the product is zero so anyóne of the terms should be zero.
⇛(x - 1) = 0 or (x + 6) = 0
⇛x - 1 = 0 or x + 6 = 0
⇛x = 1 or x = -6
Here we got two solutions of the equations. This means thet are in correct form.
Answer: The value of X is 1 or -6.

Answer:
3052.1 in³
Step-by-step explanation:
The volume of a sphere is given by the formula ...
V = 4/3πr³ . . . . r is the radius
The radius is half the diameter, so is 9 in. Then the volume is ...
V = (4/3)(3.14)(9 in)³ = 972(3.14) in³ ≈ 3052.1 in³
State the slope and y-intercept for the graph of
- 8x + y = -12.
Answer:
y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.
To read the slope, you must have x and its coefficient on opposite sides of the equal sign.
So you get
y = 8x – 12 when you add 8x to both sides
Next, the y intercept is found when x = 0
y = 8x – 12
y = 8(0) – 12
y = – 12
The y intercept is -12 or in point form (0, – 12)
Answer
slope = 8
y intercept = – 12

Answer:
y = mx + b is the slope intercept form of writing the equation of a straight line
Step-by-step explanation:
y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is.
i a stoc kcar model is built to scale of 1 cm : 2.5 ft and the model measures 7.7 cm in length, what will be the length of actual stock car?
Answer:
19.25 ft
Step-by-step explanation:
for every one cm the actual car is 2.5 feet. therfore it would be 7.7 times 2.5 which equals 19.25
Pls help me with this
Step-by-step explanation:
a)
clearly, A and B are mirrored images of each other around the x-axis.
and the equation of the x-axis is simply
y = 0
b)
this is trickier.
first of all, the mirror line is now vertical and not horizontal.
and where is it ? of course, in the middle between A and B.
how many units are there between A and B ?
I am counting 5. so, the middle between them is 2.5 units.
so, let's go e.g. from A 2.5 units to the right (in the direction of B).
where do we end up ? at x = 0.5
and that is also the equation of the vertical line there.
again
x = 0.5

The vertices of quadrilateral PQRS are listed.

Which of the following is the strongest classification that identifies quadrilateral PQRS?
A.
Quadrilateral PQRS is a rectangle.
B.
Quadrilateral PQRS is a trapezoid.
C.
Quadrilateral PQRS is a square.
D.
Quadrilateral PQRS is a parallelogram.
Answer:
Rectangle
Step-by-step explanation:
Did it on
Option A is correct.
As, Quadrilateral PQRS is a rectangle because it has four right angles.
What is a rectangle?A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
here, we have,
Explanation:
Given:
The coordinate of vertices of quadrilateral PQRS are P(3,7), Q(6,-2), R(0,-4), S(-3,5).
Slope for two points (x1,y1) and (x2,y2) is given by:
m = y1-y2/ x1 - x2
.so, we get,
The slope of PQ is = -9/3 = -3
The slope of QR is = -2/-6 = 1/3
The slope of RS is = -3
The slope of SP is = 1/3
we know that,
The slopes of perpendicular lines are opposite reciprocals.
we get,
∴ all pair of sides has slopes that are negative reciprocals;
this means the figure has 4 right angle, so it is a rectangle.
Therefore, Quadrilateral PQRS is a rectangle because it has four right angles.

Solve the inequality-8≤3x-17<19
Answer: The answer is X∈[3,12).
Answer:
-8≤3x-17<19
-8+8 ≤ 3x - 17 + 8 < 19 + 8
0 ≤ 3x - 9 < 27
0 ≤ 3x - 9 + 9 < 27 + 9
0 ≤ 3x < 36
0 ≤ 3x / 3 < 36/3
0 ≤ x < 12
So x can be 0 or less than 12. A number between 0 and 12
