Which system of equations does this graph represent?
Linear graph and parabola. They intersect at negative 1, negative 5 and 2, negative 2
Group of answer choices
y = x2 − 6
y = −x − 4
y = x2 + 6
y = x + 4
y = x2 + 4
y = −x + 4
y = x2 − 6
y = x − 4
An explanation would also be appreciated!
Answer:
y = x^2 - 6 and y = x - 4
Step-by-step explanation:
It's x^2 - 6, because the parabola was moved 6 down, and positive slope, so in the linear, x is positive

Gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year
What is Economic indicator ?An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance.
We need to find the which economic indicator is the measure of all goods and services produced within a given economy in one year.
A trade deficit occurs when a country imports more than it exports
A trade surplus is an economic measure of a positive balance of trade, where a country's exports exceed its imports.
GDP measures the monetary value of final goods and services—that is, those that are bought by the final user—produced in a country in a given period of time
Hence, gross domestic product is the economic indicator to measure of all goods and services produced within a given economy in one year

Mercury has a mass of 3.30 * 10 23 kg.
Mars has a mass of 6.42 x 10 23 kg.
How many times more massive is Mars than Mercury?
51x 10 23 kg
51
1.95 10 23 kg
1.95
Answer:
Option (4)
Step-by-step explanation:
Mass of Mercury = 3.3 × [tex]10^{23}[/tex] kg
Mass of Mars = 6.42 × [tex]10^{23}[/tex] kg
Therefore, ratio of the masses of Mars and Mercury = [tex]\frac{6.42\times 10^{23} }{3.30\times 10^{23}}[/tex]
= 1.95
[tex]\frac{\text{Mass of Mars}}{\text{Mass of mercury}}=1.95[/tex]
Mass of Mars = 1.95 × (Mass of Mercury)
Therefore, mass of Mars is .95 times more than Mercury.
Option (4) will be the answer.

A Trinomial expression has 3 terms.
If it has degree 2, then the exponent of the leading term will be 2.
If the leading coefficient is -5, then the leading term will be [tex]-5x^2[/tex]
Written in standard form: [tex]y=-5x^2+bx+c[/tex]
We are not given any information about the coefficients of the remaining two terms, so we can substitute any values for these:

Which system models this situation? h = 3t 10 and h = -16t2 15t 6 10t 3 and h = -16t2 6t 15 -16t2 3t 10 and h =-16t2 15t 6 -16t2 10t 3 and h = -16t2 6t 15.
The system of equations that model this situation are [tex]h = -16t^{2}+15t +6[/tex] and [tex]h = 3t +10[/tex].
As we know,
Projectile motion formula,
[tex]h = -16t^{2}+vt +h_{0}[/tex].....(1)
Where, t = time since the measuring tape was thrown.
h = height in feet above the ground.
What is a projectile motion?Projectile motion is a form of motion experienced by an object or particle that is projected near the Earth's surface and moves along a curved path under the action of gravity only.
It is given that:
v =15 feet/sec
h₀ = 6 feet
So, (1) will become,
[tex]h = -16t^{2}+15t +6[/tex]
Also, h = distance of worker's arm from the ground + speed of bucket * time(t)
[tex]h = 3t +10[/tex]

Proof:
I need help on this question
Answer:
Step-by-step explanation:
They all give 8r so that is not the distinguishing characteristic.
The first one in column A gives
12r + t - 4r + 6t
12r - 4r + t + 6t
8r + 7t
This is the third one in column B
2nd one in Column A
12r + 2t - (4r + 10t) Remove the brackets
12r + 2t - 4r - 10t Pay close attention to 10t becoming -10t. The minus sign effects both terms inside the brackets.
12t - 4t + 2t - 10t Combine
8r - 8t Now take out the common factor (8)
8(r - t) That's the top one in column B
3rd one in column A
12(r + t) - 6(r +t) + 4(r + t) - 2(r+t) They all have r+t so r + t is a common factor)
(r+t) [12 - 6 + 4 - 2] Combine
(r + t ) [ 8 ]
This is the second one in column B
The trick here is to look out for common factors. Don't remove the brackets. But it takes a bit of practice before you know that

?% of $8,000,000 = $1,600,000
Answer:
20%
Step-by-step explanation:
To solve, we can calculate how much 1,600,000 is of 8,000,000 as a decimal and then solve from there.
Let's say our missing value is x.
x of 8,000,000 = 1,600,000
"x of something", in this case, can be rephrased as "x * something", so we have
x * 8,000,000 = 1,600,000
divide both sides by 8,000,000 to isolate x
x = 1,600,000/8,000,000 = 0.2
to convert from a decimal to percentage, multiply by 100
0.2 * 100 = 20
20% is our answer

The polynomial that is prime is given by Option C: [tex]10x^2 - 4x +3x +6[/tex]
What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Checking all the listed polynomials for them being prime or not:
Case 1: [tex]x^3+3x^2+2x+6[/tex]Rewriting it as:
[tex]x^3+3x^2+2x+6 = x^2(x+3) + 2(x+3) = (x^2 + 2)(x+3)[/tex]
shows that this polynomial has factors. Thus, it isn't prime polynomial
Case 2: [tex]x^3 + 3x^2 -2x -6[/tex]Rewriting it as:
[tex]x^3 + 3x^2 -2x -6 = x^2(x+3) -2(x+3) = (x^2-2)(x+3)[/tex]
shows that this polynomial has factors. Thus, it isn't prime polynomial
Case 3: [tex]10x^2 - 4x +3x +6[/tex]We can rewrite it as:
[tex]10x^2 -4x + 3x -6 = 10x^2 -x -6 = f(x) \: \rm (say)[/tex]
This polynomial is prime polynomial as it is irreducible in terms of polynomials having their coefficients as integers.
Case 4: [tex]10x^2 -10x + 6x - 6[/tex]
It can be factored as:
[tex]10x(x-1) + 6(x-1) = (x-1)(10x-6)[/tex]
This is not a prime polynomial.

Please help me with these questions in algebra 1 and show work:
Answer:
I’m not gonna show you a graph but these instructions should help…
For the first equation.
You have
5y = -3x + 15
So we have to put it in y=mx + b format.
We can isolate y.
Divide 5 on both sides.
y = -3/5 x +3
You have your equation right htere.
The y intercept (b) here is 3 following the format y=mx +b
So now you plot a point on (0,3) since thats your Y- intercept, first point of contact on the y axis. Now for the slope. Slope goes by rise / run. Think of it as you get out of bed, you have to get up first before you run off to whatever you do.
Now you can just follow the instructions give, -3/5 is -3 rise and 5 run. Since a -3 rise is going down, we do down since its a negative slope here.
Starting from (0,3) you go down 3 units, then at that point go to the RIGHT 5 units. You should have a plotted point on, (5,0). Now following the postulate, if two lines exists in a plane that a line is created, draw a line using the 2 points from (0,3) to (5,0). (Draw throguh the whole thing, not segment and make sure it fills up the whole coordinate plane)
That is your equation.
For the second equation its the same thing, but this time it’s an inequality.
It’s the same gist and the equation is already simplified due for you!
Start on the y- intercept which is -2, or (0,-2)
Now since it’s a positive slope, because its 1/2, rise 1, run 2. From (0,-2) rise up 1 and then run two units to the RIGHT.
You should end up with, (2, -1)
Construct a line throught he two points (not segment line, fill the whole plane).
Now since its an inequality, we don’t stop there.
It’s a less then sign so when constructed the line that fills the whole plane.
You have to shade the bottom RIGHT of your screen that has a line throguh it.
So basically a line is made though two points and you have the whole plane covered. Shade in the bottom part WITHOUT crossing over the line.

Ifa=12 and 120% of a is equal to 80% of b, then what is
a+b?
Rsm question
Answer:
a + b = 30
Step-by-step explanation:
If we convert the percentages to decimals (120% = 1.2 & 80% = 0.8), we can use this equation to find B: 1.2A = 0.8b
Since we know a, we then have 1.2 * 12 = 0.8b
Solving for B gives us b = 18
12 + 18 = 30
