Answer:
Step-by-step explanation:
The systems of linear equations can have:
1. No solution: When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. One solution: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. Infinitely many solutions: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts never have more than one solution.
Write an expression that shows “the product of 3 and the sum of 6 and 8.”
A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19
Kristen is trying to finish 1/2 of her test every 2/3 hour. How many hours will it take Kristen to complete her whole test?
Answer:
4/3
Step-by-step explanation:
4) -4x - 10.2
I need the answer to this question asap please.
Answer: -2.55
Explanation: First add 10.2, and then the equation becomes -4x = 10.2.
Then, you just divide by -4 from both sides of the equation, and you get x = -2.55. :]
Answer:
21 - 4x
Step-by-step explanation:
Multiply 10 and 2 to get 20.
41 - 4x - 20
Subtract 20 from 41 to get 21.
21 - 4x

=4.50000
Step-by-step explanation:
Slope = 1.000/2.000 = 0.500
x-intercept = 9/-1 = -9.00000
y-intercept = 9/2 = 4.50000

x=5/2
Step-by-step explanation:
what is the sum of all positive integer cubes that are less than 100
Step-by-step explanation:
2^3=8
3^3=27
4^3=64
so if you add all the positive integer cubes it will be 8+27+64=99
hence 99 is less than 100
Hence solved.
Camila Cabello wants to order cheesecakes over the internet. Each cheesecake costs $15.99 and shipping for the entire order is
$9.99. Camila has no more than $100 to spend. Choose the statement that best describes how many she can purchase.
She can purchase no more than 6 cheesecakes.
She can purchase no more than 5 cheesecakes.
She can purchase 6 cheesecakes.
She can purchase 5 cheesecakes.
She can purchase about 5.6 cheesecakes.
She can purchase at least 6 cheesecakes.
She can purchase at least 5 cheesecakes.
Answer:
she can purchase 5 cheesecakes
Step-by-step explanation:
15.99*5=79.95
if we add 9.99 for the shipping of thw whole order
79.95+9.99=89.94
what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
Answer:
The equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4
Step-by-step explanation:
We need to write equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units.
When the graph is shifted towards right h units the equation becomes f(x)=(x-h) using it for our scenario:
If x is shifted right 3 units it will become f(x)=|x-3|
When the graph is shifted down h units the equation becomes f(x)=x-h using it for our scenario:
and Shifted down 4 units the equation will become: f(x)=|x-3|-4
So, the equation for f(x)=|x| if it is what is the equation for f(x)= |x| shifted to the right 3 units and Shifted down 4 units is f(x)=|x-3|-4

Paul creates the diagram to help him factor 4x2 + x – 5 by using double grouping. His diagram is incomplete.
Which terms should Paul write in squares M1 and M2?
a) 5x and −4x
b) –5x and 4x
c) –2x and 10x
d) 2x and −10x
Answer:
5x and -4x
Step-by-step explanation:
Because Paul is looking for M1 and M2 in order to get a total that is +x and a product that is equal to -20x^2, we can see that 5x and -4x help Paul get the products he wants.
Answer:
A; 5x and −4x
Step-by-step explanation:
r(x) = -4x² + 5x1
r(-3) =?
Answer:
therefore when x = -3, r(x) = -51
Step-by-step explanation:
This is a function of r(x), so when it says r(-3), the x value is -3, so we have to find the value of r(x) when x=-3.
just plug in the x value in to the given equation
r(-3) = [tex]-4(-3)^{2}[/tex]+5(-3)
r(-3) = -4(9)+5(-3)
r(-3) = -36+-15
r(-3) = -51
therefore when x = -3, r(x) = -51
Answer: r(x) = -51
If the 1 is not a +1 or a -1
It is very unusual to have a 1 in that position.
Step-by-step explanation:
Substitute the value given (-3) in place of x, and evaluate the function.
r(-3) = -4(-3)² + 5(-3)
r(-3) = -4(9) - 15
r(-3) = -36 -15
r(-3) = -51
Solve by substitution

Which function has a domain of all real numbers?
A. y=-x½+5 B. y=(2x)⅓-7 C. y=(x+2)¼ D. y=-2(3x)⅙?
Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.
