Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy. Which is the first error that Tomas made? Tomas substituted the 3 for x when he should have substituted 6 for x. Tomas added 6 to both sides of the equation instead of subtracting 6. Tomas should have written the equation as . Tomas substituted 3 for x when he should have substituted 3 for y.
Correct question is;
Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost,
Where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
2x + 6y = 12
2(3) + 6y = 12
6 + 6y + 6 = 12 + 6
6y = 18
y = 3
which is the first error that tomas made?
A) tomas substituted the 3 for x when he should have substituted 6 for x.
B) tomas added 6 to both sides of the equation instead of subtracting 6.
C) tomas should have written the equation as 3x + 6y = 12.
D) tomas substituted 3 for x when he should have substituted 3 for y.
Answer:
Option B: tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
We are told that; x represents the number of pounds of granola while y represents the number of pounds of walnuts.
Now, we are told that He can spend a total of $12 on the ingredients. Also that he buys 3 pounds of granola that costs $2.00 per pound while the walnuts cost $6 per pound.
Thus;
2x + 6y = 12
He buys 3 pounds of granola. Thus;
2(3) + 6y = 12
6 + 6y = 12
The next step here is to subtract 6 from both sides but Tomas added 6 to both sides instead.
Thus, option B is the correct answer.

A flying squirrel jumped from a tree branch and floated to the ground. The squirrel's height (in meters above the ground) ttt seconds after jumping is modeled by
h(t)=-2t^2+4t+30h(t)=−2t

+4t+30h, left parenthesis, t, right parenthesis, equals, minus, 2, t, squared, plus, 4, t, plus, 30
Suppose we want to know the height of the squirrel above the ground at its highest point.
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
h(t)=h(t)=h, left parenthesis, t, right parenthesis, equals
2) At its highest point, how far above the ground was the squirrel?
Answer:
1) The vertex form of the function reveals the highest point:
h(t)=-2(t-1)^2+32
2) At its highest point, the squirrel was 32 meters above the ground.
Explanation:
took the dumb quiz
The vertex format of the given equation so that the answer appears as a number in the equation is [tex]h(t) = -2(t-1)^2+32[/tex] and at its highest point, the squirrel is 32 meters above the ground.
Given :
A flying squirrel jumped from a tree branch and floated to the ground. [tex]h(t) = -2t^2+4t+30[/tex]1) Write the given equation in vertex formate so that the answer appears as a number in the equation.
[tex]h(t) = -2t^2+4t+30\\h(t) = -2(t^2-2t-15)\\h(t) = -2(t-1)^2+32[/tex]
2) From the above equation it can be concluded that at its highest point, the squirrel is 32 meters above the ground.

Elevation represents distance from sea level. Positive numbers represent elevations that are above sea level and negative numbers represent elevations that are below sea level.
A hiker recorded the distance from sea level that she hiked on 4 different days in the table below.
On which day did the hiker travel the furthest distance.
A. Monday
B. Tuesday
C. Wednesday
D. Thursday
Answer:
The answer is C i got it right i am not lieing
Step-by-step explanation:
On Wednesday the hiker had the greatest elevation of 8.74 km.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Given, Elevation represents the distance from sea level.
Positive numbers represent elevations that are above sea level and negative numbers represent elevations that are below sea level.
We know distance is always positive so if we look through the table on Wednesday the hiker has hiked - 8.75 km,
Now modulus of - 8.75 is | - 8.75 | = 8.75, so on Wednesday the hiker has the greatest distance covered.

Mr. Bishop and his family leave on a car trip Saturday morning at 5am and arrive at their destination at 11am. When he began the trip the car's odometer read 44 520 km and when he arrived it read 45 000 km. What was the average speed for the trip?
Answer:
Average speed =80km/h
Step-by-step explanation:
Given data
initial odometer reading= 44 520 km
final odometer reading= 45 000 km
distance covered= final odometer reading-initial odometer reading
distance covered= 45 000 -44 520
distance covered=480km
time taken = 11-5= 6hours
we know that speed= distance /time
speed=480/6
speed= 80km/h

f(x)=1 – 2x - 3x^4 as
x → infinity, f(x) → -infinity
A. True
B. False
Answer:
true
Step-by-step explanation:
took the quiz
The polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have a polynomial:
f(x) = 1 – 2x - 3x⁴
or
f(x) = - 3x⁴ - 2x + 1
As we increase the value of x the value of f(x) decreases because the leading term is negative.
Leading term = -3
Thus, the polynomial f(x) = 1 – 2x - 3x⁴ as x → infinity, f(x) → -infinity is true because the leading term is negative.

Tommy runs a lemonade stand to raise money for Baker Children's Hospital. Last weekend, he made 8 quarts of lemonade to sell. Saturday was rainy, so he only sold 6 cups. The weather was better on Sunday, so he sold 18 cups. How many quarts of lemonade does he have left?
Answer:
2 quarts
Step-by-step explanation:
In order to solve this problem we first need to calculate the total amount of lemonade, Tommy made in Cups. Since 1 quart holds 4 cups we simply multiply the 8 quarts that Tommy made by 4 like so...
8 * 4 = 32 cups of Lemonade
Now that we know that Tommy made a total of 32 cups of lemonade we can subtract the number of cups he sold each day from the total.
32 - 6 - 18 = 8 cups
Finally, we see that after selling 6 cups on Saturday and 18 cups on Sunday he has 8 cups left. Now we simply divide this by 4 to turn the cups back into quarts
8 / 4 = 2 quarts
Answer:
2 quarts

Which equation represents the line that passes through the point (−2,2) and is parallel to y - 8= 12x ?
Answer:
y=12x+26
Step-by-step explanation:
We need an equation that passes through (-2,2) and is parallel to y-8=12x.
For this problem, we are going to use point slope form. Point slope form is written like this: [tex]y-y_{1} =m(x-x_{1})[/tex]. Parallel lines on graphs also have the same slope and different y-intercepts. Let's start plugging our known values. We will start with the slope. We know that the slope is 12, so m=12.
[tex]y-y_{1}=12(x-x_{1})[/tex].
We also know that [tex]y_{1} =2, x_{1}=-2[/tex]. Now let's solve
[tex]y-2=12(x+2)\\y-2=12x+24\\y=12x+26[/tex]
