what is the value of x?
6(x-4)=10
Answer:
[tex]\boxed{\sf{x=\dfrac{17}{3}=5.6 }}[/tex]Step-by-step explanation:
Use a distributive property.
Distributive property:
[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]
⇒ 6(x-4)=10
First, divide by 6 from both sides.
⇒ 6(x-4)/6=10/6
Solve.
⇒ x-4=5/3
Add by 4 from both sides.
⇒ x-4+4=5/3+4
Solve.
5/3+4
4*3/3+5/3
4*3+5/3
4*3=12
12+5=17
x=17/3
Dividing is another option.
17/3=5.6
x=17/3=5.6
Therefore, the final answer is x=17=5.6.I hope this helps you! Let me know if my answer is wrong or not.

Which of the following expressions are equivalent to -2(5 – 3)?
Choose all answers that apply:
A
-10 - 6
B
-10 + 6
None of the above
Peno
Sos
Answer:
It's B
-10 + 6
Step-by-step explanation:
Here, we gotta use the distributive property.
the -2 will distribute to the 5, which will make the -10
then, the -2 will also distribute to the -3 (the minus is the negative) which will make the 6
So, that should give you the -10 + 6, which is B
hope this helped :)
Answer:
[tex]\boxed{\sf{B.-10+6}}[/tex]Step-by-step explanation:
Use the distributive property.
Distributive property:
→ A(B+C)=AB+AC
→ -2(5-3)
Multiply.
→ -2*5=-10
→ -2*3=-6
Rewrite the problem down.
→ = -10+6
Therefore, the correct answer is B. -10+6.I hope this helps you! Let me know if my answer is wrong or not.

68°
Z
Answer:
X=121, y=59, w=59, z=53
Step-by-step explanation:
To find w, we know that the interior angles of a triangle are 180°. Thus ↓
180-31-90=59
For y, we know that y and w are opposite angles. Therefore, y = w = 59.
To find x, we know that there is a one straight line, so therefore we use ↓
180-59=121
Lastly, to find z, we know that the interior angles of a triangle are 180°. Thus ↓
180-59-68=53

Answer:
f(g))(0) = 0
Step-by-step explanation:
assuming you mean f(g)(0)
evaluate g(0) then substitute the value obtained into f
x = 0 then g(0) = 2 ← from graph (0, 2 ) , then
x = 2 then f(2) = 0 ← from graph (2, 0 )
What is the approximate area of Laura’s yard?
To find the area of an irregular shape (in general)
⇒ is best to split it into different regular shapes
⇒ (in this case), let's split into a half-circle and a square
Area of the half-circle:
⇒ half the area of a circle ([tex]\pi r^2[/tex])
⇒ Area of half-circle = [tex]\frac{1}{2}\pi r^2[/tex]
r: length of radius ⇒ half of length of the diameter ⇒ 8.5m[tex]\pi[/tex] = 3.14Area of Half Circle = [tex]\frac{1}{2}\pi (8.5)^2 = 113.5m^2[/tex]
Area of square
⇒ length * width
⇒ Area of Square = 17 * 17 = 289[tex]m^2[/tex]
Total Area = 113.5 + 289 = 402.5 ≈ 402[tex]m^2[/tex]

The diameter of a circle is 18 ft. Find its area in terms of pi
Answer:
81π
Step-by-step explanation:
To find the area of a circle, the formula is πr^2
r=radius, and radius is half the diameter, so it is 9.
Plug the radius into the formula to get 81π
(9^2*π)

If f(1)=2 and f(n) = f(n-1)^2+4 then what is the value of f(3)?
Answer:
f(3) = 68
Step-by-step explanation:
Given:
[tex]\sf f(1)=2[/tex]
[tex]\sf f(n) = f(n-1)^2+4[/tex]
[tex]\sf \implies f(2) = f(1)^2+4[/tex]
[tex]\sf \implies f(2) = 2^2+4=8[/tex]
[tex]\sf \implies f(3) = f(2)^2+4[/tex]
[tex]\sf \implies f(3) = 8^2+4=68[/tex]
Find the area of a regular octagon with an apothem length of 10 and a side length of 6.
Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²
Answer:
Step-by-step explanation:
Preliminary task
Draw a regular octagon.
Draw a perpendicular from the side's midpoint to the center. (That is the apothem).
Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.
The octagon has 8 such triangles.
Area one triangle
Area = 1/2 * side * apothem
side = 6
apothem = 10
Area = 1/2 6 * 10
Area = 30
Area of 8 such triangles.
Area = 8 * area of 1 triangle
area 1 triangle = 30
Area of 8 such triangles = 30*8 = 240

Answer:
-x + 1
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
we want to find (f-g)(x)
(f-g)(x) is the same as saying f(x) - g(x)
f(x) - g(x) = (2x + 3) - (3x + 2)
==> remove parenthesis and apply negative sign
f(x) - g(x) = 2x + 3 - 3x - 2
==> combine like terms
f(x) - g(x) = -x + 1

Step-by-step explanation:
(2,5);(−6,−3)
(x1,y1)=(2,5)
(x2,y2)=(−6,−3)
Use the slope formula:
m=
y^2−y^1

=1
Answer:
m=1
Answer:
[tex]\boxed{\sf{1}}[/tex]
Step-by-step explanation:
To solve this problem, you have to use a slope formula.
Slope formula:
[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{Rise}{run} }[/tex]
[tex]\sf{y_2=(-3)}\\\\\sf{y_1=5}\\\\\sf{x_2=(-6)}\\\\\sf{x_1=2}[/tex]
Rewrite the problem down.
[tex]\sf{\dfrac{(-3)-5}{(-6)-2} }[/tex]
Solve.
[tex]\sf{\dfrac{(-3)-5}{(-6)-2}=\dfrac{-8}{-8}=\boxed{\sf{1} }[/tex]
Therefore, the slope is 1, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.
