x = -2, 7
Please help I'll give the brainiest to the right answer!
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Because vertical angles are always equal, we want to solve [tex]50x+10=70x-10[/tex].
We can add 10 to both sides to get [tex]50x+20=70x[/tex].
We can subtract [tex]50x[/tex] from both sides to get [tex]20=20x[/tex].
Lastly, we divide both sides by 20 to get [tex]1=x[/tex].
So, [tex]\boxed{x=1}[/tex] and we're done!
The check is left as an exercise to the reader.
Answer:
x= 1
Step-by-step explanation:
TO solve you can use the equation 50x+10=70x-10.
First, subtract 10 from both sides:
50x= 70x-20
Then subtract 70x from both sides:
-20x=-20
Then divide by -20:
x=1
Check your work:
50(1)+10=70(1)-10
50+10=70-10
60=60
Hope this helps!

x^2 - 6x + 1 = 0 by completing the square
Answer:
See below.
Step-by-step explanation:
x^2 - 6x + 1 = 0
x^2 - 6x = -1
We halve the coefficient of x (which is -6/2 = -3) and square it, then add this to both sides:-
x^2 - 6x + (-3)^2 = -1 + (-3)^2
x^2 - 6x + 9 = -1 + 9
(x - 3)^2 = 8
x - 3 = ±√8
x = 3 ± √8
= 0.17, 5.83 to 2 decimal places.
Answer:
[tex]x = - 2 \sqrt{2} + 3 \\ or \\ x = 2 \sqrt{2 } + 3[/tex]

simplify 4b²−2b+7b−6b+1
Answer:
=4b^2−b+1
Step-by-step explanation:
4b2+−2b+7b+−6b+1
4b2+−2b+7b+−6b+1=(4b2)+(−2b+7b+−6b)+(1)
=4b^2−b+1
4b²−2b+7b−6b+1
solution:first combine light terms.
[tex] {4b}^{2} - 2b + 7b - 6b + 1[/tex]
light terms equal:
[tex] - 2b + 7b - 6b[/tex]
let's solve:
[tex] {4b}^{2} - 2b + 7b - 6b + 1[/tex]
[tex] = { 4b}^{2} - b + 1[/tex]

Given f(x)=-2x-1, solve for x when f(x)=-7
Answer:
The answer is -15.
Step-by-step explanation:
1. 2x - 1
2. 2(-7) - 1
3. (-14) - 1
4. -15
By plugging in our x value, we are able to use PEMDAS to multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.
Volume = 154 cm cubic
height = 16 cm

FIND THE DIAMETER OF THE CYLINDER
#SHOW THE WORKING PLZZ
Cylinder Volume
Level : JHSV = hπr²
154 cm³ = 16 cm × 3.14 × r²
154 cm³ = 50.28 cm × r²
r² = 154 cm³ : 50.28 cm
r² = 3.0625 cm²
r = 1.75 cm
d = 2r
d = 2 × 1.75 cm
d = 3.5 cm
So, the diameter of the Cylinder is 3.5 cm

During the fall, you decide to rake leaves and charge $12 for coming to a house and raking, and then $9 for every hour you rake. If you make $57 in each of 3 houses you went to in one day, how many hours did you spend shoveling?
Answer:
15
Step-by-step explanation:
For 1 house, the charge just to go to a house is $12.
In each house you made $57.
$57 - $12 = $45
The charge per house just for raking was $45.
You charge $9/hour.
$45/($9/hr) = 5 hours
You shoveled 5 hours in each house.
3 * 5 hours = 15 hours
Answer: 15 hours

Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
50 = -1/3b + 20
what is b?
To find b, start by subtracting 20 from both sides:
50 = -1/3b + 20
-20 -20
30 = -1/3b
Now isolate b by dividing both sides by -1/3:
30/(-1/3) = (-1/3b)/(-1/3)
-90 = b
b is 90!
