Write an equation of the line passing through the points (3,8) and (-2,-22)
Answer:
y=6x+8 or y=6x-22
Step-by-step explanation:
use the equation y=mx+b
m is the slope and b is the y-intercept
to find the slope use the equation m = y2-y1 over x2-x1
-22 - 8 / -2 - 3 = -30 / -5 = 6
6 is your slope and for the y-intercept you can choose whichever y-intercept to put into the equation.
HOPE THIS HELPS!!
What is the probability that both spinners land on red or orange?
A) 1/9
B) 1/3
C) 4/9
D) 2/9
Answer:
A, the probability is 1/9. you get this because you multiply the probabilities
in this example its 1/3 times 1/3 so you get 1/9
Step-by-step explanation:
Noah is buying a pair of jeans and using a coupon for 10%off. The total price is $56.70 which includes $2.70 in sales tax. Noah’s purchase can be modelled by the equation
x-0.1x+2.70=56.70
what does the solution to the equation mean in this situation?
How can you verify that 70 is not a solution but 60 is the solution?
Answer:
See below.
Step-by-step explanation:
So, we know that Noah's purchase can be modeled by the equation:
[tex]x-0.1x+2.70=56.70[/tex]
Part 1)
The solution to the equation will be the value of x.
In this case, x will represent the original price of the jeans.
We know that Noah has a coupon for 10% off the original price of the jeans.
So, 0.1x will represent how much of the original price Noah gets a a discount on.
Therefore, (x - 0.1x) represents the total cost of the jeans after the coupon.
So, x is our original price of the jeans.
Part 2)
To verify that 70 is not a solution, we can simply substitute 70 for x and check whether or not the equation is true. So:
[tex](70)-0.1(70)+2.7\stackrel{?}{=}56.70[/tex]
Multiply:
[tex]70-7+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]63+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]65.7\neq56.7[/tex]
However, we can verify that 60 is the solution by substituting. So, substitute 60 for every x:
[tex](60)-0.1(60)+2.7\stackrel{?}{=}5.7[/tex]
Multiply:
[tex]60-6+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]54+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]56.7\stackrel{\checkmark}{=}56.7[/tex]
So, 60 is indeed the solution and is the value of x.
So, this means that $60 was the original price of the jeans.
Answer:
$60

i need help with 1/2x+13=9
im in the 8th grade btw
Answer:
-8
Step-by-step explanation:
You are wanting to solve for x
First you want to subtract 13 on both sides-
1/2x = -4
Now you want to divide on both sides-
x = -8
Answer:
1/-8
To find:
x
Step-by-step explanation:
1/2x+13=9
take 13 to the LHS. when you take 13 to the LHS it becomes negative
1/2x=9-13
1/2x=-4
by cross multiplying,
2x × -4=1
-8x=1
x=1/-8
hope it helps you!!
Can you help with these two plz? Number a and b if you can do c and d for me that would be great as well!
Answer:
a) x = 60. b) b = 110. c) x = 20. d) x = 30.
Explanation:
For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.
For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.
For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.
For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.

SOLVE NUMBER TWO I WILL GIVE BRAINLIST!! USE PIE PLEASE.
Answer:
see explanation
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
Here C = 32π , thus
πd = 32π ( divide both sides by π )
d = 32
Thus a coin with diameter 32 mm should fit through a slot of 35 mm

F(x)=20x Calculate how high he will be at 5, 25, and 60 minutes.
F(5)=
F(25)=
F(60)=
Answer:
f(5) = 100
f(25) = 500
f(60) = 1200
Step-by-step explanation:
All you had to do was pulug in the f(x) into the x.
F(5) = 20 (5) = 100
f(25) = 20(25) = 500
f(60) = 20(60) = 1200

-14 = -4(9x - 1)
Answer:
x = 0.5
Step-by-step explanation:
First, distribute -4 to the parentheses:
-14 = -4(9x - 1)
-14 = -36x + 4
Subtract 4 from both sides:
-18 = -36x
Divide each side by -36
0.5 = x
x = 0.5
➠ -14 = -4(9x - 1)
Multiplying by -1 on both sides,
we ge[tex]t[/tex]
➠ 14 = 4(9x - 1)
➠ 14 = (4 × 9x) - (4 × 1)
➠ 14 = 36x - 4
➠ 36x = 14 + 4
➠ 36x = 18
➠ x = 18/36
➠ x = 1/2
➠ x = 0.5

−3 = x −11
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
-3 = x - 11
Step 2: Solve for x
Add 11 to both sides: 8 = xRewrite x = 8Step 3: Check
Plug in x to verify it's a solution.
-3 = 8 - 11
-3 = -3
Answer:
X = 8
Step-by-step explanation:
8-11= -3. I think the easiest way to solve this if you are new to negative numbers is to use a number line.
Good luck!
