Answer:
[tex]x = 3[/tex]
Step-by-step explanation:
Step 1: Determine the equation
So we know that our equation does not have a y-intercept which means that it doesn't intersect ANYWHERE on the y-axis. Therefore, this means that our equation will be a straight vertical line that doesn't move side to side and just goes straight up and down. We also know that our point is (3, 6) which means that our x-value will be 3 and this is where the equation will be located.
There are several ways to display our answer where x = 3 is the most common way which basically means give me all of the y-values for the same x value of 3. Another way of saying it is x - 3 = 0 which either way when adding 3 to both sides gives you x = 3 which is what I usually go with.
Answer: [tex]x = 3[/tex]
Answer:
x = 3 or x - 3 = 0
Step-by-step explanation:
Given
It does not have a y-interceptPasses through the point (3, 6)Solving
If the line cannot touch the y-axis, it has to be parallel to it (in other words, the line must be vertical)Since the x-value is constant for a vertical line and it passes through the point (3, 6), the equation of the line will be :x = 3 or x - 3 = 0Please help!! Will mark brainlyest.
Solve 4+3(x-2)=2x-4.
Answer:
x=-2
Step-by-step explanation:
isolate the variable and the numbers
Answer:
-2
Step-by-step explanation:
4+3(x-2)=2x-4
distibute 3 to (x-2)
4+3x-6=2x-4
simplify
3x-2=2x-4
add -4 (becomes +4) to -2
3x+2=2x
subtract 3x
2=-x
divide the negative

Circumference of the wheel is :
[tex]\qquad \tt \dashrightarrow \:c = 2 \pi r[/tex]
c = circumference r = radiusNumber of revolutions = 13, and distance travelled is 65 m.
So, we can infer that :
[tex]\qquad \tt \dashrightarrow \:c = \frac{distance \: covered}{number \: of \: revolutions} [/tex]
Now, equate both the equations ~
[tex]\qquad \tt \dashrightarrow \:2 \pi r = \frac{distance \: covered}{number \: of \: revolutions} [/tex]
[tex]\qquad \tt \dashrightarrow \:2 \pi r = \frac{65}{13} [/tex]
[tex]\qquad \tt \dashrightarrow \:2 \pi r = 5[/tex]
[tex]\qquad \tt \dashrightarrow \:r = \frac{5}{2 \pi} [/tex]
[tex]\qquad \tt \dashrightarrow \:r = \frac{5}{3.14 \times 2} [/tex]
[tex]\qquad \tt \dashrightarrow \:r = \frac{5}{6.28} [/tex]

suppose h(t)=-0.2t^2+2t models the height, in feet of a ball that is kicked into the air where as t is given time in seconds. after how many seconds does the ball reach maximum height. what is the maximum height of the ball after how many seconds does the ball reach the ground
Answer:
Step-by-step explanation:
h=vt-16t²+s
t= -b/2a
t= -2/.4
t=5 seconds
h= -0.2(5)²+2(5)
h= -0.2(25)+10
h= -5+10
h= 5ft
It takes 5 sec. to reach its max height so it will take 5 sec. to hit the ground so 5+5=10 10 sec. total.

Step-by-step explanation:
The exchange rate is 1. 65 Bosnian markas per U. S. Dollar. The price of a refrigerator in Bosnia is 1964 markas while in the U. S. It is $1357. The real exchange rate is approximately
We will see that the real exchange rate is approximately 1.447 markas per U.S. dollar.
What is the real exchange rate?Here we need to perform a change of units procedure.
We know that the price of a refrigerator in Bosnia is 1964 markas, while in the US is $1357.
Then we can write the relation:
1964 markas = $1357
Now, we want to find the value in markas for a single dollar, then we divide both sides by 1357 to get:
(1964 markas)/1357 = $1357/1357
1.447 markas = $1
This means that the exchange rate is 1.447 markas per U.S. dollar.

Determine the central and radius of the circle of equation given below
x2+y2-4x+6y-12=0
Answer:
centre = (2, - 3 ) and radius = 5
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 4x + 6y - 12 = 0 ( add 12 to both sides )
x² + y² - 4x + 6y = 12 ( collect x/ y terms )
x² + 4x + y² + 6y = 12
using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(-2)x + 4 + y² + 2(3)y + 9 = 12 + 4 + 9
(x - 2)² + (y + 3)² = 25 ← in standard form
with (h, k ) = ( 2, - 3 ) and r = [tex]\sqrt{25}[/tex] = 5
Answer:
center of the circle = (2, -3)
radius of the circle = 5
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given equation:
[tex]x^2+y^2-4x+6y-12=0[/tex]
Collect like terms:
[tex]\implies x^2-4x+y^2+6y-12=0[/tex]
Add 12 to both sides:
[tex]\implies x^2-4x+y^2+6y=12[/tex]
Complete the square for both variables.
Add 4 to both sides for x. Add 9 to both sides for y.
[tex]\implies x^2-4x+4+y^2+6y+9=12+4+9[/tex]
[tex]\implies (x^2-4x+4)+(y^2+6y+9)=12+4+9[/tex]
Factor the two variables:
[tex]\implies (x-2)^2+(y+3)^2=25[/tex]

Answer:
80%
Step-by-step explanation:
We can generalize from a specific example.
Let's assume that the season is 100 games long.
We have played 75% of the season, which is 75 games
We have won 40% of the games that we have played, so we have won 40% of 75 games, which is 30 games.
So, we must have lost 45 games.
To finish the season with as many wins as losses, of the 25 games we have left to play, we will have to win 20 games and lose 5.
To win 20 out of the last 25 games will be 20/25 = 0.80 = 80%

Step-by-step explanation:
Using distance formula
d^2 = ( x1-x2)^2 + (y1-y2)^2
d^2 = (3a - -a)^2 + (b - -5b )^2
d^2 = (4a)^2 + (6b)^2
