Solve 4(x + 1) = 4x + 4
Answer:
x is all real numbers
Step-by-step explanation:
4(x + 1) = 4x + 4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
x is all real numbers
is a=3 b=4 c=2 and d=-2 find the value of 3b²c-2ad
And ac-bd/7
Step-by-step explanation:
remember : calculations are usually done from left to right, but multiplications and divisions come before + and -.
and exponents come before multiplications and divisions.
and minus a negative number always turns into plus a positive number.
so,
3b²c - 2ad = 3×4²×2 - 2×3×-2 = 96 - -12 = 96 + 12 = 108
and
ac - bd/7 = 3×2 - 4×-2/7 = 6 - -8/7 = 6 + 8/7 = 7 1/7 ≈ 7.143
52 plus what equals 208
Answer:
The answer is 156 Hope it helps!

Answer:
solution:
here,
or, (2x+30)°=(3x+20)°
or,2x+30°=3x+20°
or, 2x+3x=30°+20°
or, 5x=50°

Sameer had $600 in his savings account. He wants to have at least $100 in the account
by the end of the year. He withdraws $20 a week for expenses. How many weeks can
Sameer withdraw money? Important! When you multiply or divide by a negative
number, the inequality sign reverses.>+<
amounts in savings - amount per week x number of weeks 2 amount of money at the
end of the year
30 weeks
25 weeks
O
5 weeks
20 weeks
Answer:
The answer is 25 weeks
Step-by-step explanation:
Let, Number of weeks = x
Now, the required expression is
∴[tex]600-20x\geq 100\\=>-20x\geq -500\\=>20x\leq 500\\x\leq 25[/tex]

Find the y-intercept of the line: 6x – 3y +6=0
Answer:
Step-by-step explanation:
The y-intercept exists where the x coordinate is 0. Therefore, we can find it by plugging in a 0 for x and solving for y:
6(0) - 3y + 6 = 0 and
-3y + 6 = 0 and
-3y = -6 so
y = 2
2. Find the domain of the function (f/g)(x) where f (x)= x^2 – 9 and g(x)= x^2 - 4x+3
A (-infinity, infinity)
B (-infinity, 1) (1, infinity)
C (infinity, 1) (1,3) (3, infinity)
D (-infinty, -3) (-3,-1)(-1, infinity)
Answer:
I think you mean C.
Step-by-step explanation:
f(x) / g(x) = (x + 3)(x - 3)
==========
(x - 3)(x - 1)
f(x)/g(x) = (x+3) / (x - 1)

In a rotation, pairs of corresponding points are on parallel lines?
Step-by-step explanation:
Corresponding angles are congruent if the two lines are parallel. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.
Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
3. Square with side length 40 ft
Answer:
Area of the square:
A = a² = 40² = 1600 ft²Area of the circle:
A = πr² = 3.14*(40/2)² = 1256 ft²Probability of landing in the shaded region:
P = 1256/1600 = 0.785 or 78.5%Answer:
78.5%
Step-by-step explanation:
We can find the area of both shapes then divide to find the probability.
Square area:
40 * 40 = 1600ft²
Circle area with diameter [ 1/4πd² ]:
1/4π(40)²
1/4π(1600)
0.785(1600)
1,256
Now divide both areas to find the probability.
1256/1600 = 0.785
0.785 * 100% = 78.5%
Best of Luck!

Answer:
Ithink the answer is 6 hope it helps please mark as brainliest
Answer:
a^2+3a+2
Step-by-step explanation:
(a + 1) × (a + 2)
a x a = a^2
a x 2 = 2a
1 x a = 1a
1 x 2 = 2
a^2 +2a+1a+2
2a+1a =3a
a^2+3a+2

Trapezoid p is the image of trapezoid P after a translation. Y 7+ . р на дъл от - 1 -7-6-5-4-3-2-1 -2+ 11 2 3 4 5 6 7 1 PY 1 - - -51 -67 Which statement correctly describes the translation of trapezoid P to create the image Pl? A. 3 units to the right and 5 units down B. 4 units to the right and 1 units down O C. 8 units to the right and 5 units down D. 9 units to the right and 6 units down
Answer:
C. 8 units right and 5 units down
Step-by-step explanation:
since it's only a translation, take one point as an example. lets say the bottom right point on trapezoid P is point A, and the translated point on P' is A'. the coordinates of A are (-3,2) while the coordinates of A' are (5,-3). (-3+x,2+y)=(5,-3). -3+x=5, x=8; 2+y=-3, y=-5
Find f(-3) if f(x) = -2x^2 + x + 3 and g(x) = -2x + 1
HELP please explain how to do it
Since you're trying to find f(-3), your function that you have to plug -3 into will be f(x).
f(-3) = -2(-3)^2+(-3)+3
f(-3) = -2(9)+(-3)+3
f(-3) = -18-3+3
f(-3) = -18 is your final answer
