Answer:
-2, -3, 3/2
Step-by-step explanation:
Factor 2x^2+ 3x – 9
(x+3)(2x-3)
(x + 2)(x+3)(2x-3) - the zeros are basically the opposite of the numbers here
x+2=0
x=-2
x+3=0
x=-3
2x-3=0
x=3/2
To plot just put the numbers on the x line because it is (x,0)

If y= 1/2x and x = -14 find y
Answer:
y = -7
Step-by-step explanation:
y = 1/2x
x = -14 (given)
y = 1/2 × (-14)
= -7
Answer:
y= -7
Step-by-step explanation:
Just plug -14 in for x to calculate y
y=1/2(-14)= -7

Answer:
a = 57 mm is the answer.
Step-by-step explanation:
a = ?
b = 76 mm
c = 95 mm
According to the Pythagoras theorem,
a² + b² = c²
a² + 76² = 95²
a² + 5776 = 9025
a² = 9025 - 5776
a² = 3249
a = 57 mm
∴ a = 57 mm is the length of the missing leg.
Answer:
57 mm
Step-by-step explanation:
To solve for a, we can use the Pythagorean Theorem.
a² + b² = c²
We have to solve for a, and we are given values for b and c, c being the hypotenuse.
This is what we know-
a² + 76² = 95²
We can simplify this to-
a² + 5776 = 9025
To solve for a, we have to isolate the variable on on side of the equals sign. So, we can subtract 5776 from both sides.
a² + 5776 - 5776 = 9025 - 5776
Simplify.
a² = 3249
Finally, to solve for a, find the square root of a².
[tex]\sqrt{3249^{2}[/tex] = 57
So, a = 57 mm

Answer:
c = 9.4m is the answer
Step-by-step explanation:
a (length of the telephone pole) = 9m
b (distance between the pigeon and the pole) = 3m
c = ?
According to the Pythagorean theorem,
a² + b² = c²
9² + 3² = c²
81 + 9 = c²
c² = 90
c = 9.4m
∴ the pigeon will fly 9.4m

If a figure has elght vertices and 12 edges, how many faces does it have? 10
8
6
4
Answer:
It would have 6 faces
Step-by-step explanation:
In any convex polyhedron:
let v be the number vertices , e is the number of edges and f is the number of faces then;
....[1]
As per the statement:
If a figure has eight vertices and 12 edges
⇒v = 8 and e = 12
Substitute in [1] to solve for f, we have;
⇒
Subtract 6 from both sides we have;
f = 6
Somebody Please help!!!
Answer:
Slope, m = -8
Step-by-step explanation:
Given the following data;
Points on x-axis (x1, x2) = (2, 3)
Points on y-axis (y1, y2) = (5, -3)
To find the slope, m;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {-3 - 5}{3 - 2} [/tex]
[tex] Slope, m = \frac {-8}{1} [/tex]
Slope, m = -8/1
Slope, m = -8

How will the appearance of the graph change if the a value in the function is decreased, but remains greater than 0
a) the graph will increase at a slower rate
b) the graph will show a decreasing, rather than increasing, function
c) the graph will show an initial value that is lower on the y-axis
d) the graph will increase at a constant additive rate, rather than a multiplicative rate
Answer:
C
Step-by-step explanation:
in exponential equations f(x)=ab^x , a is the intial amount while b is the growth factor. you are just decreasing a so the intial value is lower (=^w^=)

Answer:ok
Step-by-step explanation:
If P = (3,2), find the image
of P under the following rotation.
270° counterclockwise about the origin
([?], [])
Given:
The point P = (3,2) is rotated 270° counterclockwise about the origin.
To find:
The image of the given point after rotation.
Solution:
If a point rotated 270° counterclockwise about the origin, then the rule of rotation is:
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex]P(3,2)\to P'(2,-3)[/tex]
Therefore, the image of given point P = (3,2) after the rotation of 270° counterclockwise about the origin, is P'(2,-3).
