Answer:
x = —2
Step-by-step explanation:
h(x) = 4x — 1
if h(x) = -9 then 4x — 1 = -9
So:
[tex]4x - 1 = - 9 \\ 4x = - 9 + 1 \\ 4x = - 8 \\ x = - 2[/tex]
Answer:
x = -2
Step-by-step explanation:
[tex]-9=4x-1\\-8=4x\\-2=x[/tex]
solve for x
2x + 4 + 2x -9 + 8 = 180
Answer: Simplifying
2x + 4 + 2x + 8 + 2x + 8 = 180
Reorder the terms:
4 + 8 + 8 + 2x + 2x + 2x = 180
Combine like terms: 4 + 8 = 12
12 + 8 + 2x + 2x + 2x = 180
Combine like terms: 12 + 8 = 20
20 + 2x + 2x + 2x = 180
Combine like terms: 2x + 2x = 4x
20 + 4x + 2x = 180
Combine like terms: 4x + 2x = 6x
20 + 6x = 180
Solving
20 + 6x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 6x = 180 + -20
Combine like terms: 20 + -20 = 0
0 + 6x = 180 + -20
6x = 180 + -20
Combine like terms: 180 + -20 = 160
6x = 160
Divide each side by '6'.
x = 26.66666667
Simplifying
x = 26.66666667
Step-by-step explanation:
Answer: x=
44.25
Step-by-step explanation: (2x+2x)+(4+−9+8)=180 4x+3−3=180−3 4x/4=177/4 x=44.25
five more than one-third of a number is -2. Find the number
Answer:
x = -21
Step-by-step explanation:
Words To Algebra:Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
Isolate x:5 + (1/3)x = -2 [tex]\longmapsto\\[/tex] Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7 [tex]\longmapsto\\[/tex] Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
Check:5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2

Lisa likes to go to one movie per week. She usually spends $12 on her ticket and $10 on a drink and popcorn. How much money would she save in one year if we went on Tuesday’s when the price of a ticker was half off and she didn’t have any snacks?
Step-by-step explanation:
there are 52 weeks per year.
she would save on one visit
12/2 = $6 plus the $10 for snacks = $16
so, she would save in one year
52×16 = $832

64t-16t^2>28 how do i solve this?
Answer:
0.5 < t < 3.5
Step-by-step explanation:
[Given] 64t-16t^2>28
[Rewrite] 64t - 16t² > 28
[Subtract 28 from both sides] 64t - 16t² - 28 > 0
[Reorder] - 16t² + 64t - 28 > 0
[Solve Using The Quadratic Formula] 0.5 < t < 3.5

Paula has a dog that weighs 3 times as much as Carla's dog. The total weight of the dogs is 76 pounds. How much does Paula's dog weigh? Use the diagram to find the weight of Paula's dog.
Answer:
Paula's dog weighs 57lbs and Carla's dog weighs 19lbs
Step-by-step explanation:
So Paula's dog will be "p" and Carla's dog will be "c"
This means p = 3c and that p + c = 76
Replace p with 3c
3c + c = 76
4c = 76
c = 19
Now solve for p
p + (19) = 76
p = 57

Step-by-step explanation:
Answer:
x = 12.633, -0.633
Step-by-step explanation:
x^2 -12x + 36 = 44
the underlined part is (x - 6) ^2
(x - 6)^2 = 44
(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)
(x - 6 ) = + 6.6332495807108
x = 12.6332495807108 = 12.633
(x - 6 ) = - 6.6332495807108
x = - 6.6332495807108 + 6
= -0.6332495807108 = -0.633
The dimensions of a rectangular prism are 3 cm, 15 cm, and k cm. Its volume is
90 cm. Find the value of k.
Answer:
k = 2 cm
Step-by-step explanation:
3 x 15 x k = 90 cm^3
45 x k = 90 cm^3
k = 90/45 = 2 cm
The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?
Answer: Length = 25, width = 7
Step-by-step explanation:
Let width be w, and length be 3w + 4.
Perimeter of a rectangle = 2l + 2w
64 = 2(3w + 4) + 2w
64 = 6w + 8 + 2w
64 = 8w + 8 [subtract 8 from both side]
56 = 8w [Divide 8 from both side]
w = 7
Plug w in l, where l = 3w + 4 = 21 + 4 = 25
Theres a 4 at the bottom but i couldn't get it in
Answer:
See answer below.
Step-by-step explanation:
1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot
there because this is your starting point.
2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and
closer to -2 because the point is -1 .75. Remember this point is not on the
graph.
3. Now move up from that point to 4.5 and put a dot at that place. The point is in the Q II , to the left top.
