Graph: y = 3x - 5
Plz help
Answer:
The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!
hope this helped!
Answer:
Step-by-step explanation:
y=3x-5 is a line
pick any 2 points for example
(x=0, y=(3*0)-5=-5) so one point is (0,-5)
(x=2, y=(3*2)-5= 1) so another point is (2, 1)
draw a line trough points (0, -5) and (2, 1)
You purchase a video game for $150. You make a down payment of $25. You pay the rest of the money you owe in 5 equal monthly payments with no interest. How much is each monthly payment?
Answer: So basically for this you just need to multiply. The answer is 25
each month since 5x30=150 and you already made a down payment of 25. So 5x30=150-25=125.

What is a quadratic equation?A basic quadratic equation, or a second-order polynomial equation with a single variable, is represented by the equation x : ax² + bx + c = 0, where a≠0 for the variable x. As it is a second-order polynomial equation, which is ensured by the algebraic fundamental theorem, it must have at least one solution.
The standard equation for a hyperbola centered at the origin is:
(x²)/(a²) - (y²)/(b²) = 1
where "a" and "b" are the lengths of the transverse and conjugate axes, respectively. To find the value of "b" for the given hyperbola equation, we need to first rewrite it in the standard form.
(x²)/(24²) - (y²)/(b²) = 1
Multiplying both sides by (24²)(b²), we get:
b²(x²) - (24²)(y²) = (24²)(b²)
Dividing both sides by (24²), we get:
b²(x²)/(24²) - y² = b²
Comparing this with the standard equation, we can see that a = 24 and b is the square root of the constant term, which is b² = 576. Therefore, b = 24.
However, the given directrix of x = 576/26 is not consistent with the equation of the hyperbola. The directrix for a hyperbola with center at the origin and transverse axis along the x-axis is given by x = a²/b. Using the value of a = 24, we can find the directrix as:
x = (24²)/b
Setting this equal to 576/26, we get:
(24²)/b = 576/26
Solving for b, we get:
b = 16
Therefore, the correct answer is (B) 16.

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
y=-3x + 3
y=-3x - 6
y = 3x - 3
y = 3x - 1
Answer:
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
The equation will be of slope-intercept form: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
We are given slope m =-3, we need to find y-intercept b
Finding y-intercept
using slope m=-3 and point (-1, 6)
[tex]y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3[/tex]
So, y-intercept b is 3
Now the equation of line having slope m= -3 and y-intercept b = 3 is
[tex]y=mx+b\\y=-3x+3[/tex]
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.

Integrate both sides with respect to t :
∫ dy/dt dt = ∫ -12t ² dt
y(t) = -4t ³ + C
Use the initial condition to solve for C :
5 = -4•0³+ C
C = 5
So
y(t) = -4t ³ + 5
and the answer is D.
Alternatively, you can directly apply the fundamental theorem of calculus:
[tex]\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du[/tex]
[tex]\implies y(t)=5-4u^3\bigg|_0^t[/tex]
[tex]\implies y(t)=5-4t^3[/tex]

Answer:
y=1 3/5x+-5
Step-by-step explanation:
So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.
Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries express the answer as dollars. Cents
Answer:
$0.15
Step-by-step explanation:
Given that:
Cost of banana per pound = $0.80
Amount of banana bought = [tex]2\frac{1}{4}=2.25\ pounds[/tex]
Cost of strawberries per pound = $1.10
Amount of strawberries bought = [tex]1\frac{1}{2} = 1.5\ pounds[/tex]
To find:
How much more money was spent on bananas than Strawberries.
Solution:
Here, first we need to find how much money was spent on bananas and strawberries.
Then we need to subtract the smaller value from larger value.
From the given values, we can calculate the following:
Cost of banana for 2.25 pounds = $0.80 [tex]\times[/tex] 2.25 = $1.8
Similarly,
Cost of strawberries for 1.5 pounds = $1.10 [tex]\times[/tex] 1.5 = $1.65
Money more spent on bananas = $1.8 - $1.65 = $0.15
which table of values matches the equation y=2x-3
Answer:
What are the possible answer??/
Step-by-step explanation:
The set of points satisfying the equation y = 2x - 3 is a. {(0, -3), (1, -1), (1.5, 0), (2,1)}.
An equation is the combination of 2 or more expressions separated by the equality sign(=), signifying the equality of expressions.
To obtain the set of points satisfying the equation y = 2x - 3.
The given equation is y = 2x - 3.
Let's take x = 0,
y = 2 × 0 - 3 = -3,
the point is (0, -3).
Let's take y = 0,
0 = 2x - 3
2x = 3
x = [tex]\frac{3}{2}[/tex]
x = 1.5,
the point is (1.5, 0).
Let's take x = 1,
y = 2 × 1 - 3 = -1,
the point is (1, -1).
Let's take y = 1,
1 = 2x - 3
2x = 1 + 3
2x = 4
x = [tex]\frac{4}{2}[/tex]
x = 2,
the point is (2,1).
Hence, the set of points satisfying the equation is {(0, -3), (1, -1), (1.5, 0), (2,1)}.

Lucy has a goal of walking at least 15 miles she walks at a rate of 5 miles per hour which inequality can Lucy used to find H the number of hours she should walk in order to meet or exceed her goal
Answer:
5h>15
Step-by-step explanation:
✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h
✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as
5h>15
