Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16

A triangle has a perimeter of 23 feet. Find the value of X
In which quadrant would the point
(9.-10) be located?
a) Quadrant 1
b) Quadrant 2
c) Quadrant 3
d) Quadrant 4
Answer:
D
Step-by-step explanation:
Start with the 9. It goes to your right. It is on the plus x axis.
You are either in quad 1 or quad 4
We need the - 10 to decide which.
+ 10 would go up and that would mean quad 1
- 10 mean going down so you are in Quad 4
Which interval notation represents the set of all numbers greater than -2 and less
than or equal to 3?
Answer:
yes
Step-by-step explanation:
Answer:
(- 2, 3 ]
Step-by-step explanation:
parenthesis ( ) is used when the end value is not equal
brackets [ ] are used when the end value is equal
Here numbers are greater but not equal to - 2 and less than or equal to 3
(- 2, 3 ] ← is the appropriate interval notation

Answer:
[ - 4, 8 ]
Step-by-step explanation:
parenthesis ( ) is used when end values are not equal to x
brackets [ ] are used when the end values are equal to x
For - 4 ≤ x ≤ 8
Then x can equal both - 4 and 8 , so
[ - 4, 8 ] ← is the appropriate interval notation

4x^2-12x=-9
Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0
I let you try !
Jackie has two new puppies. One weights 5 9/16 pounds, and the other weighs 6 1/4 pounds. Find the difference in their weights.
Answer:big brrrrrrd
Step-by-step explanation:
yes
Answer:
11/16 pounds
Step-by-step explanation:
The difference between their weights can be found by subtracting 6 1/4 pounds from 5 9/16 pounds to find the difference. To do this we must transfer it from 1/4 to sixteenths which is 4 sixteenths. Then we subtract.
6 4/16

Find the equivalent equation that results from, halving both sides first and then subtracting
1 from both sides. Show each step. You do not have to solve the equation at the end,
Answer:
6x - 1 = 9
Step-by-step explanation:
1. first you have to divide every term in the equation by 2
12x/2 + 4/2 = 20/2
2. simplify
6x + 2 = 10
3. next you have to subtract one from both sides
6x + (2-1) = (10-2)
4. simplify
6x + 1 = 9

Are (2,9) and (-3,-6) both on the line y - 4x + 6? If not, find an equation for the line that does pass through both points.
Answer:
points doesn't lie in the given line.
Step-by-step explanation:
firmula for finding the equation of these points are
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} [/tex]
x1=2 , x2=-3, y1= 9 ,y2=-6
subtitute all values in formula
[tex] \frac{y - 9}{ - 6 - 9} = \frac{x - 2}{ - 3 - 2} [/tex]
[tex]y - 3x - 3 = 0[/tex]
if we put (2,9) and (-3,-6) in new equation then they will satisfy equation.so this is the equation where points lie in the line
is 16 a natural, whole, integer, rational or irrational number?
Answer:
6 is a natural, whole and integer
Step-by-step explanation:
16 is a natural, whole and integer
it is not rational or irrational because
rational numbers are written in p/q as well as irrational
natural numbers start from 1 till infinite
whole numbers start from 0 to infinite
integers include all the positive and negative numbers
Answer:
rational
Step-by-step explanation:
Write an equation of the line that passes through the point (-6, -9) with slope-5.
A. y + 9 = 5(20+6)
B.y +6 = 5(x +9)
c.y+9= -5(x + 6)
D.y +6 = -5(x +9)
Answer:
[tex]y+9=-5(x+6)[/tex]
Step-by-step explanation:
We are being asked to write the equation in point-slope form:
[tex]y-y_1=m(x-x_1)[/tex] where m = slope and the first point = [tex](x_1,y_1)[/tex]
In this case, the slope is -5 and the point is [tex](-6,-9)[/tex] so the equation will be:
[tex]y+9=-5(x+6)[/tex]

Simplify 4(2x3 – 5x2 + 8x + 2) - 6x - 8x3
Answer:
- 20x² + 26x + 8
Step-by-step explanation:
Given
4(2x³ - 5x² + 8x + 2) - 6x - 8x³ ← distribute parenthesis by 4
= 8x³ - 20x² + 32x + 8 - 6x - 8x³ ← collect like terms
= - 20x² + 26x + 8
