Answer:
vertex = (3, 1 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 3)² + 1 ← is in vertex form
with vertex (h, k ) = (3, 1 )

(7TH GRADE LEVEL) Read the instructions and answer questions 16-18
Answer:
Equations
Step-by-step explanation:
16:
7 · (-3) = -21
-3 · 7 = -21
-21 ÷ 7 = -3
-21 ÷ (-3) = 7
17:
-4 · (-5) = 20
-5 · (-4) = 20
20 ÷ (-4) = -5
20 ÷ (-5) = -4
18:
1.5 · (-3) = -4.5
-3 · 1.5 = -4.5
-4.5 ÷ 1.5 = -3
-4.5 ÷ (-3) = 1.5
This is 7th grade?
Hope I helped :)
Answer:
16. 7 x -3= -21
-3 x 7= -21
-21/-3=7
-21/7=3
17. -4 x -5= 20
-5 x -4= 20
20/-4=-5
20/-5=-4
18. 1.5 x -3= -4.5
-3 x 1.5=-4.5

factorise a³ - b³ + 4a-4b
Answer:
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]a^3-b^3+4a-4b[/tex]
solving the expression
[tex]a^3-b^3+4a-4b[/tex]
as
[tex]a^3-b^3[/tex][tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]
[tex]a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)[/tex]
also
[tex]4a-4b[/tex][tex]\mathrm{Factor\:out\:common\:term\:}4[/tex]
[tex]=4\left(a-b\right)[/tex]
so the expression becomes
[tex]=\left(a-b\right)\left(a^2+ab+b^2\right)+4\left(a-b\right)[/tex]
[tex]\mathrm{Factor\:out\:common\:term\:}\left(a-b\right)[/tex]
[tex]=\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Therefore,
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

The length of a rectangle is four times its width.
If the area of the rectangle is 144 ft, find its perimeter.
Answer:
y = mx + c
since m = 0
c = 9
Answer: 60
suppose: the width of a rectangle is x (x > 0)
⇒ The length of a rectangle is 4x
because the area of the rectangle is 144 ft
=> 4x.x = 144
⇔ x² = 144/4 = 36
⇒ x = 6
with x = 6 ⇒ The length of a rectangle is 4.6 = 24
the perimeter of the rectangle is (6 + 24).2 = 60
Step-by-step explanation:
Solve for y: 2x-y = 3...halp meeeh pls. thhhhxxx!
Answer: Subtract 2x from both sides of the equation. Multiply each term in −y=−3−2x - y = - 3 - 2 x by −1 - 1 . Multiply (−y)⋅−1 ( - y ) ⋅ - 1 .
Step-by-step explanation:
Answer:
y= -3
Step-by-step explanation:
to find y- intercept, substitute x= 0
2 x 0 - y = 3
y= -3

Answer:
1.58 meters
Step-by-step explanation:
a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules
Answer:
150 JoulesStep-by-step explanation:
Step one:
Given data
Force F= 10N
the distance is described by the coordinate = (0,0) to (15,0)
hence the distance = 15m in the x-direction.
Step two:
Required is the work done
we know that work done is expressed as
Wd= Force* Distance
Wd= 10*15
Wd= 150 Joules

Dave bought 4 cookies at a bake sale if each cookie cost 0.85 and he paid with a twenty dollar bill how much change should he get back
Answer:
$16.60
Step-by-step explanation:
4 x 0.85 = $3.40
20 - 3.40 = 16.6
Dave should get back $16.60 in change.
Answer:
$16.6 dollars back
Step-by-step explanation:
The answer is $16.6 because 0.85 times 4 is 3.4 and 20 minus 3.4 is 16.6
How would you do this and how would you graph it on a number line
Answer:
k=-5,5
Step-by-step explanation:
first you calculate (by switching the -6 to the other side)
|k|<-1+6
second you add the -1+6 and get |k|<5
the other part will be that the |k| will turn to - negative.
now you will have -k<5 then not you have to take the negative of -k to only have, (k<-5), k equalling to -5.
But remeber you always flip the < to > when you have the greater-to-equal sign or less-to-equal sign.
4x= x + 18 X= whattttttttttt
Answer:
4x=x+18x=
We move all terms to the left:
4x-(x+18x)=0
We add all the numbers together, and all the variables
4x-(+19x)=0
We get rid of parentheses
4x-19x=0
We add all the numbers together, and all the variables
-15x=0
x=0/-15
x=0

Find the slope of the line that passes through (-3, 2) and (6, 2).
Answer:
slope = 0
Step-by-step explanation:
(-3, 2) and (6, 2)
slope = (y1 - y2)/(x1 - x2)
remember, either x or y can be used but you have to be consistent
slope = (2-2)/(-3-6)
slope = 0/(-9)
slope = 0
Answer: no slope or 0
Step-by-step explanation:
The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], it still ends up with 0.
What is 0 divided by 0
Answer:
0
Step-by-step explanation:
You can’t divided 0 by 0 so it’s 0
