Answer:
x = -3.5
Step-by-step explanation:
POE = PROPERTY OF EQUALITY
3*2 + 2x + 1 = 0
6 + 2x + 1 = 0 ## ^ Multiplication
7 + 2x = 0 ## ^ Combine like-terms
2x = -7 ## ^ Subtraction POE
x = -3.5 ## ^ Division POE
Answer:
X=0
Step-by-step explanation:
Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.
Solve using substitution. y = 1
3x − 7y = 8
Answer:
(5, 1)
Step-by-step explanation:
Substitute:
[tex]3x - 7*1 = 8\\3x - 7 = 8\\3x = 15\\x = 5[/tex]
so the solution is (5, 1)
What single decimal multiplier would you use to decrease by 14% followed by a 9% decrease?
Answer:
the single decimal multiplier is 0.7826
Step-by-step explanation:
The computation of the single decimal multiplier is given below:
Given that
It is reduced by 14% that followed by 9% decrease
So according to this, the following calculation is required
= (1 - 0.14) × (1 - 0.09)
= 0.86 × 0.91
= 0.7826
Hence, the single decimal multiplier is 0.7826

Manufacturing a company is designing a new rectangular shipping box that must have a
volume of 24 cubic inches. The company has created a box with a width that is 2 inches less
than its length. The height is 5 inches greater than the length. What are the dimensions?
Answer:
3in by 1in by 8in
Step-by-step explanation:
Volume of the box = Length × Width × Height
Given
Volume = 24in³
If the width is 2inhes less than the length
W = L-2... 2
Also if the height is 5 inches greater than the length, then;
H = L+5 ... 3
Substitite 2 and 3 into the formula.
V= LBH
24 = L(L+5)(L-2)
24 = L(L²+3L-10)
24 = L³+3L²-10L
L³+3L²-10L-24 =0
Factorize
The factored form is
(L+2)(L²+L−12) = 0
L²+L-12 = 0
L²+4L-3L-12 = 0
L(L+4)-3(L+4) = 0
(L+4) = 0 and L-3 = 0
L = 3in
W = L-2
W = 3-2
L = 1in
H = L+5
H=3+5
H = 8in
Hence the dimension is 3in by 1in by 8in
name a combination of 12 coins that equals 3 dollars (has to be dimes & quarters)
Answer:
63(P) 20
Step-by-step explanation:
The required number of coins are would only by quarters so that 12 coins shows the values of $3.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
dime = $0.1
quarter = $0.25
Now,
Let the number of dimes be x and number of quarter be y,
x + y = 12
x = 12 - y - - -- -(1)
According to the question,
0.1x + 0.25y = 3 -- - -(2)
y = 12
Now,
x = 0
Thus, the required number of coins are would only by quarters so that 12 coins shows the values of $3.

Pls helpppp
Answer:
Infintely many solutions
Step-by-step explanation:
I'm going to assume that the capital y is equal to the lowerase y
if you subtract y and two from both sides in the second equation you get
-y=2x-2
you then divide by -1 to get it into a normal form
y= -2x+2
this is the same as the first equation, these lines are the same
Identify the zeros of each function. y=(x-7)^2
9514 1404 393
Answer:
x = 7 (multiplicity 2)
Step-by-step explanation:
When the function is written in factored form, the zeros are the values of the variable that make the factors zero.
y = (x -7)(x -7)
The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.
__
On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).
What is the equation of the line? Can someone help me with this? Thanks! :)
Answer: y = ¹/₂x + 2
Step-by-step explanation: This is slope-intercept form. y = mx + b
m is the slope. Rise/run
The difference in y-values is the rise. The difference in x-values is the run.
Look for places where the graphed line intersects the grid. Count the squares. Here, the graphed line rises 1 square as it runs 2 squares.
b is the y-intercept. Here, that is 2
