Answer:
1. A 2. B
Step-by-step explanation:
Whatever happens to x must also happen to y.
For the first question, x is doubled, which means that the value of y is also doubled.
For the second question, if the value of x triples, then the value of y triples as well, which means that it would be multiplied by 3.
We can check to see if these two answers are true by inputting values into the equations.
For the first equation, let's use the example x = 2
y = 5(2)
y = 10
If the value if x doubled, it would become x = 4
y = 5(4)
y = 20
As you can see, when the value of x doubled from 2 to 4, the value of y also doubled from 10 to 20.
You can do something similar for the other equation.
Answer:
10,404/334,084
Step-by-step explanation:
Given the polynomial
289r^2 - 102r + c
We are to find the value of c that will make it a perfect square
Divide through by 289
289r²/289 - 102r/289 + c/289
Half of the coefficient of r is 1/2(102/289)
Half of the coefficient of r = 102/578
Square the result
r² = (102/578)²
r² = 10,404/334,084
Hence the required constant is 10,404/334,084

Answer:
The standard form of the equation is -3x + y = -19
Step-by-step explanation:
To find the standard form, we first need to note that the slope will be 3 since parallel lines have the same slope. Then we can use point-slope form and manipulate into standard form.
y - y1 = m(x - x1)
y - 5 = 3(x - 8)
y - 5 = 3x - 24
-3x + y - 5 = -24
-3x + y = -19
Answer:
- x = sandwiches
- y = wraps
- y = -3/4x +420
- y-intercept = 420
- m = -3/4
Step-by-step explanation:
This is a reading comprehension question. The problem statement tells you ...
"x number of sandwiches" and "y number of wraps."
You should be able to deduce that ...
x represents the number of <em>sandwiches</em>
y represents the number of <em>wraps</em>
___
The equation 3x+4y=1680 is put into slope-intercept form by solving for y.
4y = -3x +1680 . . . . . subtract 3x
y = (-3/4)x + 420 . . . .divide by 4
Comparing this to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, we see that ...
y-intercept = 420
m = -3/4
