Help please. Domain ASAP
Answer:
x ≥ -1
Step-by-step explanation:
The domain is all the possible x-values of the function.
Reading from left to right, the first x-value is x = -1 (which is included because the dot is filled in.) From there, the graph goes to the right, towards infinity.
So x is greater than or equal to -1.
x ≥ -1

A wood board 59 inches long is cut into three parts. The first part is twice the
length of the second part. The third part is 5 less than the second part. How long
are the three parts?
Answer:
first part is 32 inches, second part is 16 inches, third part is 11 inches.
Step-by-step explanation:
2x + x + x - 5 = 59
4x + 64
x = 16.
we can then plug 16 in first parts expression, 2x, for 32. second part is just x so 16. 3rd part is 5 less, x-5, so 11.

An angle measures 46° more than the measure of its complementary angle. What is the
measure of each angle?
Answer:
Angle + the Complementary angle = 90 degrees. Let x be the measure of the angle under the question. Then the measure of the Complementary angle is (x+46) degrees, and you have this equation x + (x+46) = 90, or 2x+ 46 = 90, or 2x = 90 - 46 = 44. Then x =  = 22. The given angle has the measure of 22 degrees. The complementary angle is 90-22 = 68 degrees. Check. 68 - 22 = 44 degrees. Correct !!

Slove 3(t-3)=5(2t-1)
Answer:
t = 7/-4 OR -1 3/4
Step-by-step explanation:
3(t - 3) = 5(2t - 1)
3t - 9 = 10t - 5
(3t - 3t) - 9 = (10t - 3t) - 5
-9 = 7t - 5
-9 + 5 = 7t (- 5 + 5)
-4 = 7t
-4/-4 = 7t/-4
t = 7/-4 OR -1 3/4

Step-by-step explanation:
Tom makes a bet with his friend Bob. Bob wagers $100, but Tom decides to make him a deal. If Bob wins, Tom will pay him $100. If Tom wins, Bob will instead pay $1 for the first day, then every day for 10 days he must match the total amount paid so far.
For the first day, Bob will pay $1. The second day, he will pay an additional dollar, since he has only paid $1 thus far. The third day he will pay $2, the fourth $4, and so on.
If Bob has a 75% chance to win, which of the following is the closest to the amount of money Tom will make on average with this bet?

Answer:
y = 14/3 and 2
x = -13/3 and 1
(-13/3, 14/3) and (1, 2)
Step-by-step explanation:
[tex]x + 2y = 5 - - - (a) \\ {x}^{2} - {y}^{2} = - 3 - - - (b)[/tex]
for equation (a)
make x the subject of the formular:
[tex]x = 5 - 2y - - - (c)[/tex]
for equation (b)
[tex] {x}^{2} - {y}^{2} = - 3[/tex]
substitute for x as 5 - 2y in equation (b):
[tex] {(5 - 2y)}^{2} - {y}^{2} = - 3 \\ (25 - 20y + 4 {y}^{2} ) - {y}^{2} = - 3 \\ 25 - 20y + 3 {y}^{2} = - 3 \\ {3y}^{2} - 20y + 28 = 0 \\ (3y - 14)(y - 2) = 0[/tex]
therefore,
[tex]y = \frac{14}{3} \: \: and \: \: 2[/tex]
substitute for all values of y in equation (c):
for y = 14/3:
[tex]x = 5 - 2( \frac{14}{3} ) \\ \\ x = 5 - \frac{28}{3} \\ \\ x = - \frac{13}{3} [/tex]
for y = 2:
[tex]x = 5 - 2(2) \\ x = 5 - 4 \\ x = 1[/tex]
Answer:
(1, 2)
(-13/3, 14/3).
Step-by-step explanation:
x + 2y = 5
x² - y² = -3
From the first equation x = 5 - 2y
Substitute for y in the second equation:
(5 - 2y)^2 - y^2 = -3
25 + 4y^2 - 20y - y^2 = -3
3y^2 - 20y + 28 = 0
Factoring:-
(3y - 14(y - 2) = 0
y = 2, 14/3.
So when y = 2, x = 5 - 2(2) = 1.
When y = 14/3, x = 5 - 2(14/3) = -13/3.
Checking the results in the second equation:
(1, 2):-
1^2 - 2^2 = -3 Correct.
(-13/3, 14/3):-
(-13/3)^2 - (14/3)^2 = -3 Correct.

If you are performing the following translation (x,y) --> (x + 3, y -4) Determine how that would change the original ordered pair (10, 9). Select the new ordered pair after the Translation. (answer choices below)
(7, 9)
(10, 4)
(3, 10)
(13, 5)
Answer:
(13, 5 )
Step-by-step explanation:
The translation
(x, y ) → (x + 3, y - 4)
Means add 3 to the x- coordinate and subtract 4 from the y- coordinate, so
(10, 9 ) → (10 + 3, 9 - 4 ) → (13, 5 )

(x-2)/(x+1)=1/2 . find x
Answer:
x=5
Step-by-step explanation:
(x-2)/(x+1)=1/2, we use that a/b = c/d is the same as a*d = c*b
2*(x-2) = 1* (x+1), distribute multiplication over subtraction
2x -4 = x +1 , subtract x and add 4 to both sides
2x -x = 1 +4, combine like terms
x = 5
Answer: x = 5
Solve:
Given
(x - 2) / (x + 1) = 1/2
Cross multiply applied
1 (x + 1) = 2 (x - 2)
Expand parentheses and apply the distributive property
x + 1 = 2x - 4
Add 4 on both sides
x + 1 + 4 = 2x - 4 + 4
x + 5 = 2x
Subtract x on both sides
x + 5 - x = 2x - x
x = 5
Check:
Left-hand side = (x - 2) / (x + 1) = (5 - 2) / (5 + 1) = 3/6 = 1/2
Right-hand side = 1/2
1/2 = 1/2

Answer:
A.) w² + 3w in²
B.) 28 in²
Step-by-step explanation:
A.)
Let w = width and l = length.
The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.
A(rectangle) = lw = (w + 3) · w = w² + 3w
B.)
Use the polynomial we previously found to find the area.
A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²
Model:
Solve for W.
4w=5.12
Answer:
x =1.28
Step-by-step explanation:
4w=5.12
Divide each side by 4
4w/4 = 5.12/4
x =1.28
solve 4m plus 2n equals 5n for m.
Answer:
m = (3/4) n
Step-by-step explanation:
4m + 2n = 5n
The subtraction property of equality states that we can subtract 2n from both sides to isolate the m and its coefficient to get
4m = 3n
The division property of equality states that we can divide 4 from both sides to isolate only the m (we divide by 4 because anything divided by itself equals 1) to get
m = (3/4) n
