PLEASE HELP !! Timed test Which equation represents the relationship between x and y in the table?
Answer:
divided by 5
Step-by-step explanation:
Hope that helps!
Answer:
Answer Choice D- y=x/5
Step-by-step explanation:
All the numbers in the table fit in and correlate to the equation. You can substitute any of the x's into the equation and get y correctly this is why the equation y=x/5 is the solution.

Tomas combines 8.73 ounces of strawberries with 8.86 ounces of blueberries to make fruit bowls. He pours the fruit equally into 4 bowls, and has 0.23 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
8.73 Ounces
Step-by-step explanation:
8.73 + 8.86 = 17.59
17.59 - 0.23 = 17.36
17.36 divide by 4 = 8.73
Each bowl has 4.46 ounces of fruit.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
ounces of strawberries = 8.73 ounces
ounces of blueberries = 8.86 ounces
So, total ounces of fruits = 8.73 ounces + 8.86 ounces
⇒ total ounces of fruits = 17.59 ounces
Left over fruit = 0.23 ounces
So, total ounces of fruit in all bowls = 17.59 ounces - 0.23 ounces
⇒ total ounces of fruit in all bowls = 17.82 ounces
Since there are 4 bowls.
Thus, ounces of fruit in each bowl = 17.82/4 ounces
⇒ ounces of fruit in each bowl = 4.46 ounces
Thus, Each bowl has 4.46 ounces of fruit.

Greta uses 2oz of pasta to make 2/3 of a serving of pasta.How many oz of pasta are there per serving
Answer:
3oz of pasta per serving
Step-by-step explanation:
Given parameters:
Number of oz of pastas used = 2oz
Quantity of serving = [tex]\frac{2}{3}[/tex]
Unknown:
Number of oz of pasta per serving = ?
Solution:
To solve this rate problem use;
Number of oz of pasta per serving = [tex]\frac{number of oz of pasta}{number of serving}[/tex]
Number of oz of pasta per serving = [tex]\frac{2}{\frac{2}{3} }[/tex] = 2 x [tex]\frac{3}{2}[/tex] = 3oz of pasta per serving

Use the provided information to write the standard form equation of the parabola.
Opens up or down, and passes through (8,0), (13,-5), and (12,0)
Answer:
f(x) = -x² + 20x - 96Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors
So we get:
f(x) = a(x - 8)(x - 12)
The parabola passes through point (13, -5) that means if x=13 then f(x)=-5
So:
-5 = a(13 - 8)(13 - 12)
-5 = a(5)(1)
-5 = 5a
a = -1 {<0 so parabola opens down}
Therefore:
f(x) = -(x - 8)(x - 12)
And expanding:
f(x) = -(x² - 12x - 8x + 96)
So the standard form equation of the parabola:
f(x) = -x² + 20x - 96
Geometry problem plz help?
Step-by-step explanation:
let eqn be y = mx + b.
m = (9 - 1)/(2 - 4) = -4
sub (4, 1):
1 = -4(4) + b
b = 17
therefore, it's y = -4x + 17

Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55. Step 1: Write the ordered pairs (35, 41.45) and (65, 55.55). Step 2: Find the slope. M = StartFraction 55.55 minus 41.45 Over 65 minus 35 EndFraction = 0.47 Step 3: Find the y-intercept to write the equation in slope intercept form. Y minus 55.55 = 0.47 (x minus 35). Y minus 55.55 = 0.47 x minus 16.45. Y = 0.47 x + 39.1.
Answer:
y = 0.47x + 25
y1 = 41.45 and not 55.55
Step-by-step explanation:
Given that:
x = number of brochures
y = total. Cost
Total cost of 35 brochures = $41.45
Total cost of 65 brochures = $55.55
The ordered pairs :
(x1, y1) ; (x2, y2)
x1 = 35 ; y1 = 41.45 ; x2 = 65 ; y2 = 55.55
(35, 41.45), (65, 55.55)
The slope :
Slope (m) = change in y / change in x
m = (y2 - y1) / (x2 - x1)
m = (55.55 - 41.45) / (65 - 35)
m = 14.1 / 30
m = 0.47
The y intercept :
y - y1 = m(x - x1)
y - 41.45 = 0.47(x - 35)
y - 41.45 = 0.47x - 16.45
y = 0.47x - 16.45 + 41.45
y = 0.47x + 25
Lila incorrectly chose 41. 45 as y1
Answer:
C. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.
