(x+12)23-(2x-3)+16=12+5x-1
hmmmmmmmmm
Answer:
look at the attached picture
Answer:
X = -16.75
Step-by-step explanation:
Distribute.
(x + 12)23 = 23x + 276
12 + 5x -1 = 11 + 5x
Combine like terms.
23x - 2x - 5x = 16x
11 - (276 + 3+16 ) = -284
16x = -284
x = -17.75

Is this equation linear?
y=x^2+3?
Is this equation linear?
y= x/4+7 (The x/4 is a fraction)
9514 1404 393
Answer:
noyesStep-by-step explanation:
In the equation ...
y = x² +3
the largest variable exponent is 2, which is not 1. The equation is not linear.
__
In the equation ...
y = (1/4)x +7
the largest variable exponent is 1, so the equation is linear.
PLZ HELP LAST QUESTION given the piecewise function given below select all statements that are true f(x)=-x+1,x<0 -2,x=0 x^2-1,x>0 All in brackets A.F(4)=7 Bf(-1)=2 c.F(-2)=0 d.F(1)=0
Answer:
Step-by-step explanation:
Given the function f(x)=-x+1,x<0 and f(x) = x^2-1,x>0
when x = 4
f(4) = -4+1
f(4) = -3
Also f(4) = 4^2 -1
f(4) = 8-1
f(4) = 7
when x = -1
f(-1) = -(-1)+1
f(-1) = 2
Also f(-1) = (-1)^2 -1
f(-1) = 1-1
f(-1) = 0
when x = -2
f(-2) = -(-2)+1
f(-2) = 3
Also f(-2) = (-2)^2 -1
f(-2) = 4-1
f(-2) = 3
when x = 1
f(1) = -1)+1
f(1) = -2
Also f(1) = (1)^2 -1
f(1) = 1-1
f(1) = 0
From the calculation above, the correct statements are
A. F(4)=7
B f(-1)=2
d. F(1)=0

The dimensions of the box below are reduced by half. What is the constant of proportionality between the volume of the new box and the volume of the original box? Alternative text A.1/2 B.1/4 C.1/8 D.1/16
Answer:
C. 1/8
Step-by-step explanation:
Dimensions of the Original Box:
Length = 40 inches
Width = 20 inches
Height = 8 inches
Volume of original box = L*W*H = 40*20*8 = 6,400 in³
Dimensions of the New Box (½ of the dimensions of the original box):
Length = ½*40 = 20 in
Width = ½*20 = 10 in
Height = ½*8 = 4 in
Volume of original box = L*W*H = 20*10*4 = 800 in³
Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]

Tangela earns the same amount each week by babysitting. When she started this job, she had $200 in her savings account.
The table shows Tangela's savings account balance for her first month of work.
Week 0 1 2 3 4
Balance $200 $350 $500 $650 $800
Let x represent the number of weeks Tangela has been working and let y represent Tangela's account balance.
Which equation, expressed in Slope-Intercept form, represents the amount of money in Tangela's bank account over time?
Answer:
y = 150x + 200
Step-by-step explanation:
Given the table :
Week (x) __ 0 ____ 1 ____ 2 ____3 _____ 4
Balance(y) :$200_ $350_ $500_ $650_ $800
Equation in slope - intercept form:
y = mx + c
Where
x and y are the independent(x) and dependent variables (y)
C = intercept, value of y, when x = 0
m = gradient change in y per change in x
Hence,
c = $200 ; y value when x = 0
m = change in x / change in y
m = (500 - 350) / ( 2 - 1)
m = $150
Hence, equation becomes :
y = 150x + 200

You decided to get the Cinemark Movie Pass. It is a flat
fee of $8 and an additional $11.00 per ticket.
Enter the equation of the line in y= mx + b form.
Answer:
y = 11t + 8
Step-by-step explanation:
Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:
y = 11t + 8
Where "t" represents the amount of tickets bought.

A kayak is originally priced at $160. The online retailer gives a discount and the kayak is now priced at $88. Enter the percentage discount for the cost of the kayak.
Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Step-by-step explanation:
Answer:
45%
Step-by-step explanation:
O= 160
C=88
160-88=72
72 ?
160 100
72 times 100=7200
7200/160=45

If angle 1 and angle 3 are vertical angles, and m<1= (5x + 14) degrees and m<3= (7x - 4) degrees, what is the value of x, and the measure for angle 1?
Answer:
x = 9
[tex] m\angle 1= 59\degree [/tex]
Step-by-step explanation:
Since, [tex] \angle 1 \:and \:\angle 3[/tex] are vertical angles.
[tex]\therefore m\angle 1 = m\angle 3\\
\therefore (5x + 14) \degree= (7x - 4) \degree\\
\therefore (5x + 14) = (7x - 4) \\
\therefore 5x - 7x = - 4 - 14\\
\therefore -2 x = - 18\\\\
\therefore x =\frac{-18}{-2}\\\\
\huge \orange {\boxed {\therefore x = 9}} \\\\
m\angle 1 = (5x + 14) \degree\\
m\angle 1 = (5\times 9+ 14) \degree\\
m\angle 1 = (45+ 14) \degree\\
\huge \purple{ \boxed{m\angle 1 =59\degree}}[/tex]
Solve the system by substitution. Check your solution.
y = 0.8 x + 7.2.
20 x + 32 y = 48.
a. (8, -6)
b. (5, 11)
c. (-4, 4)
d. (-10, 2)
Answer:
c. (-4, 4)
Step-by-step explanation:
y = 0.8x + 7.2
20x + 32y = 48
20x + 32y = 48
20x + 32(0.8x + 7.2) = 48
20x + 25.6x + 230.4 = 48
45.6x + 230.4 = 48
45.6x = -182.4
x = -4
y = 0.8x + 7.2
y = 0.8(-4) + 7.2
y = -3.2 + 7.2
y = 4
