Answer:
The expression y = 4.85g + 0.83s can be used to determine the total cost.
Step-by-step explanation:
Given that:
Cost per pound of granola bars = $4.85
Cost per pound of sugar = $0.83
Let,
y be the total cost.
According to given statement;
y = 4.85g + 0.83s
Hence,
The expression y = 4.85g + 0.83s can be used to determine the total cost.

A.) 12.25 units
B.) 12.7 units
C.) 10.25 units
D.) 10 units
Answer:
D
Step-by-step explanation:
We can use the ratios 8:9 and x:11.25 are similar.
then we can make them fractions and solve. 8/9=x/11.25
That would make 9x=90
so the answer is D
Measure of angle 3 need help
Answer: ∠3 = 120°
Step-by-step explanation:
∠3 and m∠60° are linear pairs so they had up to 180°
∠3 + 60 = 180
Subtract both sides by 60
∠3 = 120

Answer:
Quadratic:
a.
c.
e.
i.
j.
Neither:
f.
h.
Linear:
b.
d.
g.
Step-by-step explanation:
Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.
Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.
Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher. Therefore we can simply sort these equations by the highest exponent of x present after simplifying.
To the nearest tenth, what is the perimeter of the triangle with vertices at (−2, 3), (3, 6), and (2, −2)?
9514 1404 393
Answer:
20.3
Step-by-step explanation:
The distance formula can be used to find the side lengths.
d = √((x2 -x1)^2 +(y2 -y1)^2)
For the first two points, ...
d = √((3 -(-2))^2 +(6 -3)^2) = √(5^2 +3^2) = √34 ≈ 5.83
For the next two points, ...
d = √((2 -3)^2 +(-2-6)^2) = √(1 +64) = √65 ≈ 8.06
For the last and first points, ...
d = √((-2-2)^2 +(3-(-2)^2) = √(16 +25) = √41 ≈ 6.40
Then the sum of the side lengths is ...
5.83 +8.06 +6.40 = 20.29 ≈ 20.3
The perimeter of the triangle is about 20.3 units.
The lowest temperature ever recorded in the United States was -62 degrees Celsius, in Prospect Creek Camp, Alaska. The average temperature on Mars is about -55 degrees Celsius.
Which is warmer, the coldest temperature recorded in the USA, or the average temperature on Mars? Explain how you know.
Write an inequality to show your answer. Check your work with the video when you are ready.
Answer:
United States
Step-by-step explanation:
-62 < -55?
Because on the number line, -62 is farther left than -55.
the lager value of y for which (y-1)²=4y-7 is
Answer:
the lager value of y is 4.
Step-by-step explanation:
Given;
(y-1)² = 4y - 7
Simplify as follows;
(y - 1)(y - 1) = 4y - 7
y² - y - y + 1 = 4y - 7
y² - 2y + 1 = 4y - 7
Collect like terms
y² -2y - 4y + 1 + 7 = 0
y² - 6y + 8 = 0
Factorize the equation;
y² -2y - 4y + 8 = 0
y(y - 2) -4(y - 2) = 0
(y - 2)(y - 4) = 0
y = 2 or y = 4
Thus, the lager value of y is 4.

in an academic contest, correct answers earn 12 points and incorrect answers lose 5 points. In the final round, School A starts with 165 points and given the same number of correct and incorrect answers. School B starts with 65 points and given no incorrect answers and the same number of correct answers as School A. The game ends with the Schools tied.
Part A: Which equation models the scoring in the final round and the outcome of the contest?
A.) 12x + 5x - 165 = -12x + 65
B.) 12x - 5x + 165 = 12x + 65
C.) 5x - 12x + 165 = 12x + 65
D.) 12x - 5x - 165 = 12x +65
Part B: How many answers did each school get correct in the final round?
Answer:
part a is b part b is 230 tell me if im wrong
Step-by-step explanation:
Step-by-step explanation:
Let x represent the number of correct answers School A gave.
Then x is also the number of incorrect answers School A gave and the number of correct answers School B gave.
Final score of School A
= 165 + 12x - 5x.
Final score of School B
= 65 + 12x
Hence the correct equation is
12x - 5x + 165 = 12x + 65. (B)
=> 7x + 165 = 12x + 65
=> 5x = 100
=> x = 20
Hence Schools A and B got 20 correct answers each.

A basketball team played six games. In those games, the team won by 8 points, lost by 7 , won by 9 , won by 11 , lost by 3 , and won by 6 . What was the mean difference in game scores over the six games?
Answer:
4
Step-by-step explanation:
From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6
The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6
= [8 + (-7) + 9 + 11 + (-3) + 6] / 6
= 24 / 6
= 4

28.57
Step-by-step explanation:
Write an equation in point-slope form for the line that passes through the point with the given slope.
Answer:
Slope: 3
Equation: y + 2 = 3(x + 1)
Step-by-step explanation:
Find the slope using (-1, -2) and (0, 1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-2)}{0 - (-1)} = \frac{3}{1} = 3 [/tex]
Slope (m) = 3
The equation can be represented in point-slope form, y - b = m(x - a)
Where,
(-1, -2) = (a, b)
m = 3
Plug in the values into y - b = m(x - a)
y - (-2) = 3(x - (-1))
y + 2 = 3(x + 1)

Solve for x. Please Help
Look at the box pls and help me
Answer:
y = 4x + 11
Step-by-step explanation:
From the question given above, the following data were obtained:
Coordinate = (–2, 3)
Slope (m) = 4
We can express the above in slope intercept form as follow:
Slope (m) = 4
x–coordinate (x₁) = –2
y–coordinate (y₁) = 3
y – y₁ = m(x – x₁)
y – 3 = 4(x – –2)
y – 3 = 4(x + 2)
y – 3 = 4x + 8
Make y the subject of the expression by rearranging
y = 4x + 8 + 3
y = 4x + 11
Therefore, the slope intercept form is
y = 4x + 11
