9514 1404 393
Answer:
x can be any value (infinite number of solutions)
Step-by-step explanation:
The equation simplifies to ...
2(x -2) +3 = 2x -1
2x -4 +3 = 2x -1
2x -1 = 2x -1
This is true for every value of x. There are an infinite number of solutions.
80^2 - 45^2 = a^2 - b^2
ans pls in working, thnx in advance
Answer:
[tex]{a}^{2} - {b}^{2}= {(80)}^{2} -{(45)}^{2} \\(a + b)(a - b) = (80 + 45)(80 - 45) \\ = 125 \times 35 = \boxed{ 4375}✓[/tex]
4375 is the right answer.Write an equation for the line that passes through the points (0, -2) and (-4, 0).
y = - x - 4
y = -2 x - 4
y = -2 x - 2
y = - x - 2
Answer:
y=-1/2x-2
Step-by-step explanation:
I dont think any of those options are the right one so thats the correct answer
Answer: y = -1/2x - 2
Step-by-step explanation:
To first write the equation, we need to find the slope and the y intercept and write it in the form y=mx +b
To find the slope, we will find the difference between the y coordinates and divide it by the difference between the x coordinates.
The y coordinates of the points are , 0 and -2
The x coordinates of the points are -4 and 0
0 - (-2) = 2
-4 -0 = -4
Slope: 2/-4 = -1/2
Now using the formula y=mx+b, you will input the slope and use one of the given point's coordinates to solve for b the y intercept.
We will use the point (0,-2)
-2 = -1/2(0) + b
-2 = b
This means the equation will be y = -1/2x - 2

What is the exact value of x? 5⋅21^5x=16
Answer:
x= 16 /20420505
Step-by-step explanation:
Let's solve your equation step-by-step.
5(215)x=16
Step 1: Simplify both sides of the equation.
20420505x=16
Step 2: Divide both sides by 20420505.
20420505x /20420505 = 16 /20420505
x= 16 /20420505

3x-2
Answer: 47
we have:
41° + 3x - 2 = 180°
⇔ 3x - 2 = 180 - 41
⇔ 3x - 2 = 139
⇔ 3x = 139 + 2
⇔ 3x = 141
⇔ x = 141/3
⇔ x = 47

Which equation shows how the distributive property can be used to find the number of
Xs in both arrays?
Answer:
here is a simple version
lets make A equal the exponent so (A=^2 or 3 or whatever)
the exponent will be the amount of times you want to repeat the process.
Now lets make x = the first array, so x=3
and lets make y = the second array, y=7
now a simple equation would be (3x)(7y)^A or for this you could say
(3x)(7y)^6

What is the probability of the compound event of spinning a 3 on a 5 number spinner and landing on tails with a coin.
Answer:
1/10
Step-by-step explanation:
1/5 to land on the spinner, and 1/2 to land on tails. Compound prob = we gotta multiply the probabilities so we get 1/10

If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.
Answer:
y = 6
Step-by-step explanation:
If x varies inversely proportional as y.
[tex]x=\dfrac{k}{y}[/tex], k is constant of proportionality
or
k = xy
When x = 3 and y = 10
k = 3×10
k = 30
Put x = 5,
[tex]y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6[/tex]
So, the value of y is 6 when x is 5.

An arithmetic sequence has this recursive formula:
a1=9
an=an-1 -3
What is the explicit formula for this sequence?
A. an=9+(n-1)(-3)
B. an=-3+(n-1)9
C. an=9+(n-3)(-1)
D. an=-1+(n-9)(-3)
Answer:
The correct answer is:
Option A. a_n=9+(n-1)(-3)
Step-by-step explanation:
Given that
a1 = 9
[tex]a_n = a_{n-1}-3[/tex]
We can see that in recursive formula the next term is being obtained by subtracting 3 from previous term
That means that the common difference is -3
We also know the first term
The general form of explicit formula for an arithmetic sequence is:
[tex]a_n = a_1 + (n-1)(d)[/tex]
We know that a1 = 9 and d = -3
Putting the values we get
[tex]a_n = 9+(n-1)(-3)[/tex]
Hence the correct answer is:
Option A. a_n=9+(n-1)(-3)

Why do we use fractions to represent slope?
Answer:
The formula for slope is sometimes referred to as "rise over run", because the fraction onsists of the "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
Step-by-step explanation:
