a^2-b^2+4b-4 please solve it step by step i will mark you brainlest
Answers
Answer:
b = a + 2 or b = 2 - a
Step-by-step explanation:
Solve for b:
-4 + a^2 + 4 b - b^2 = 0
The left hand side factors into a product with two terms:
(2 + a - b) (-2 + a + b) = 0
Split into two equations:
2 + a - b = 0 or -2 + a + b = 0
Subtract a + 2 from both sides:
-b = -a - 2 or -2 + a + b = 0
Multiply both sides by -1:
b = a + 2 or -2 + a + b = 0
Subtract a - 2 from both sides:
Answer:
b = a + 2 or b = 2 - a

Christine must buy at least $45$ fluid ounces of milk at the store. The store only sells milk in $200$ milliliter bottles. If there are $33.8$ fluid ounces in $1$ liter, then what is the smallest number of bottles that Christine could buy? (You may use a calculator on this problem.)
Answers
Answer:
7 bottles
Step-by-step explanation:
Christie needs to buy at least 45 fluid ounces of milk at the store.
33.8 fluid ounces=1 Liter
1 fluid ounce = [tex]\dfrac{1}{33.8}[/tex] Liters
45 fluid ounces = [tex]\dfrac{1}{33.8} \times 45 =1.3313$ Liters[/tex]
Now:
1 Liter =1000 Milliliter
Therefore:
1.3313 Liter= 1000 X 1.3313 Milliliters
1.3313 Liter= 1331.3 Milliliter
Therefore, the smallest number of 200 milliliter bottles Christie must buy is:
[tex]=\dfrac{1331.3}{200}=6.7 \\\approx 7$ bottles[/tex]

∆ABC and ∆PQR are similar. ∆ABC is dilated by a scale factor of 1.25 and rotated 45° counterclockwise about point B to form ∆PQR. The side lengths of ∆ABC are , 5 units; , 4.2 units; and , 4 units. Match each side of ∆PQR to its length.
Answers
Answer:
[tex]6.25\ units,\ 5.25 \ units\ and\ 5 \ units[/tex]
Step-by-step explanation:
Given:
The scale factor = 1.25 and rotated =45°
Length of side =5 units; , 4.2 units; and , 4 units respectively.
As mention in the question the ∆ABC and ∆PQR are similar it means there sides are equal .
Therefore sides of the ∆ PQR is
[tex]= (5*1.25),(4.2*1.25),(4*1.25)\\=6.25, 5.25, 5[/tex]
Hence the length of the ∆PQR is [tex]6.25\ units,\ 5.25 \ units\ and\ 5 \ units[/tex]

Determine graphically whether the ordered pair (0, 2) is a solution of the following system of equations, and check using algebra.
x + 3y= 4
3x+y = -2
Answers
Answer: Not a solution of the System
Step-by-step explanation:
Plug in 0 for x and 2 for y for both equations.
Note, if only one of the equations is a true statement
(0.2) is not a solution. If either one of the equation is not true, the ordered pair is not a solution.
0+3(2)=4
3*2=6
0+6=6
6≠4
This was only the first equation but it was not true.
The equation is not true, so (0, 2) is not a solution of the second equation. Therefore, (0, 2) is not a solution of the system of equations.
To determine graphically whether the ordered pair (0, 2) is a solution of the system of equations, we can plot the two equations on a graph. If the point (0, 2) lies on both lines, then it is a solution of the system.
The first equation is x + 3y = 4. To plot this equation, we can first solve for y:
y = -(1/3)x + 4/3
This equation has a slope of -1/3 and a y-intercept of 4/3. So, the line will rise 1 unit for every 3 units it moves to the left. The y-intercept is 4/3, so the line will pass through the point (0, 4/3). Three units to the left of (0, 4/3) is (-3, 7/3), so the line will also pass through this point.
The second equation is 3x + y = -2. To plot this equation, we can first solve for y:
y = -3x - 2
This equation has a slope of -3 and a y-intercept of -2. So, the line will fall 3 units for every 1 unit it moves to the right. The y-intercept is -2, so the line will pass through the point (0, -2). One unit to the right of (0, -2) is (1, -5), so the line will also pass through this point.
We can check this algebraically. Substituting (0, 2) into the first equation, we get:
0 + 3× 2 = 4
6 ≠ 4
This equation is not true, so (0, 2) is not a solution of the first equation. Substituting (0, 2) into the second equation, we get:
3 × 0 + 2 = -2
2 = -2
This equation is also not true, so (0, 2) is not a solution of the second equation. Therefore, (0, 2) is not a solution of the system of equations.

The population of Happyland is 15.8 Happys per acre exactly 553 Happys live in Happyland how many acres is Happyland enter only a numerical value in the answer blank
Answers
Answer:
35 acres
Step-by-step explanation:
We have 15.8 happys per acre and the we have exactly 553 happys living in happy land.
To calculate the number of acres, we just need to divide the number of happys we have by the number by the number of happys per acre
Mathematically, that would be 553/15.8 = 35 acres
Happyland have 35 acres of Land.
Given to us:
Population of Happyland = 553 Happys
Population of Happyland per acre = 15.8 Happys per acre,
Land with Happyland in acres:
[tex]\rm {Land with Happyland in acres =\dfrac{ Total\ number\ of\ Happys}{Population\ of\ Happyland\ per\ acre}}[/tex]
Putting in the value we get,
[tex]\rm {Land with Happyland in acres =\dfrac{ Total\ number\ of\ Happys}{Population\ of\ Happyland\ per\ acre}}\\\\\rm {Land with Happyland in acres =\dfrac{553}{15.8}}\\\\\rm {Land with Happyland in acres = 35 acres[/tex]
Hence, Happyland have 35 acres of Land.

Find the value of y Log^2 32=y
Answers
Answer:
Step-by-step explanation:
First of all, I have a strong feeling that that is supposed to be
[tex]log_2(32)=y[/tex] so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is
[tex]log_b(x)=y[/tex], the exponential form of it is
[tex]b^y=x[/tex]. We will apply that here to solve for y:
[tex]2^y=32[/tex]
which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:
[tex]2^y=2^5[/tex]
Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.
The fifth-grade classes at Harvest Elementary School had an apple-tasting party. They tasted red, yellow, and green apples. There were 130 apples at the party altogether. There were 3 times as many yellow apples as green apples. There were twice as many red apples as yellow apples. How many red apples were at the party?
Answers
Answer:
78 red apples
Step-by-step explanation:
Set up the equations
r + y + g = 130
y = 3g
r = 2y
If r = 2y and y = 3g, then r = 6g
Plug in the two equations, y = 3g, and r = 6g
6g + 3g + g = 130
10g = 130
g = 13
Plug in 13 as g in the equation r = 6g
r = 6(13)
r = 78
There were 78 red apples
