The cost y in dollars for x pounds of deli meat is represented by the equation y=3.5x. Graph the equation and interpret the slope
Answer:
The graph is included below as an attachment.
The slope is the ratio of the change in the cost to the change of the amount of deli meat. The magnitude means that there is a change of 3.5 units in the cost per each pound of change of deli meat.
Step-by-step explanation:
The following linear equation represents the cost ([tex]y[/tex]), measured in dollars, as a function of the amount of deli meat ([tex]x[/tex]), measured in pounds:
[tex]y = 3.5\cdot x[/tex] (1)
The graph is included below as an attachment.
The slope is the ratio of the change in the cost to the change of the amount of deli meat. The magnitude means that there is a change of 3.5 units in the cost per each pound of change of deli meat.

Im in algebra II honors and right now we are working on parabolas and quadratic equations. Can someone help me understand how to convert from standard form to vertex form? Also how to do the opposite so convert from vertex form to standard form?
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.
The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.

Find the GFC of each set of numbers
300, 450
Answer:
The GCF is 150.
Step-by-step explanation:
hope this helps
The factors of 300 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
The factors of 450 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
Then the greatest common factor is 150.
Answer:
GFC: 150
Step-by-step explanation:
prime factorization of 300: 300 = 2 × 2 × 3 × 5 × 5
prime factorization of 450: 450 = 2 × 3 × 3 × 5 × 5
then multiply all the prime factors common to both numbers: GCF = 2 × 3 × 5 × 5
GCF = 150

Laura spent ⅕ of her money on a new pocketbook and had $90 remaining. How much did she spend on her new pocketbook?
Answer:
$18
Step-by-step explanation:
90 x 1/5
90/5
18
Answer:
$22.50
Step-by-step explanation
90 is 80% (4/5) of what number (x)? So you do 90 times 100 = 9000 and 80 times x is 80x and then 9000 divided by 80 is 112.5 so she had 112.5 to begin with but she spent 1/5 so 112.5 divided by 5 is 22.5 so 1 fifth is 22.5
Find the slope of the line that passes through the points (2, 1) and (3, 2).
Answer: M = 1
Step-by-step explanation:
Use the slope formula to find the slope
Answer:
slope=1
Step-by-step explanation:
So the equation to find slope is m=y²-y¹
-------
x²- x¹
Using that equation, we take 2= y² and 1= y¹ also 3= x² and 2= x¹
2-1 = 1
3-2 = 1
so the answer is 1!

How does the graph of y = 3 differ from y = 3x?
Answer/Step-by-step explanation:
The graph with y =3 tells you that the y variable is going to be a constant 3.
The graph with y = 3x tells you that y will climb 3 times per each x variable that is added.

i need help with this problem
Answer:
Hi!
Step-by-step explanation:
Since an isosceles triangle has two sides that are equal, those sides are A and C. To do this problem, you would need to substitute the values in for A=C, which would make it 3x+40=x+50. Bring the variables to one side and you have 2x=10, divide by 2. Your answer would be x=5. To find the value of angle A, you do 3*5=15+40=55. Then you can always check with C, 5+50=55. There you go! Hope I helped good luck! What grade are you in by the way?

Answer:
a) Recommended slope: 4, b) v = 24, c) h = 8.5
Step-by-step explanation:
a)
h = 1 / 4 of v
Slope = rise / run
= v / (1 / 4) v
= 4
Therefore, the recommended slope of the ladder is 4.
b)
h = 6
Therefore v equals 6 x 4 = 24 to satisfy the recommended slope.
c)
v = 34
Therefore h equals 34 / 4 = 8.5 to satisfy the recommended slope.
Jerry pays $1.40 per gallon for premium gasoline. He spends $16.80 and wants
to know how many gallons he bought. Which equation models this situation?
Select the correct answer.
Find the slope and the wintercept of the equation 4x + 5y=-9.
A slope = "4/5 and vintercept = `(9)/(5)
OB slope = '(4)/(5) and v-intercept = "9)/(5)
c. slope = '(4)/(5)' and y-intercept = \491(5)
D slope = '(47(5)' and vintercept = "9/5
Yo sup??
4x+5y=-9
y=(-4x)/5-9/5
we see that this is of the form y=mx+c
where m is the slope
therefore the slope of the line is -4/5
To find y intercept, put x=0
y=-4*0/5-9/5
y=-9/5
Therefore y intercept is -9/5
