Answer:
a = 3, b = -1, c = -1
Step-by-step explanation:
3x² - x - 1 = 0 ⇒ 3x² - 1x - 1 = 0
a = 3, b = -1, c = -1

1. Baking Blueberry Pies
Mrs. Berry is famous for her pies. She has been making pies in her bakery for many
years. She knows that it takes 1 2/3 cups of flour to make her special pie crust. She
buys flour in 25 pound bags and knows that each pound contains about 3 cups of flour.
How many pies can she expect to make from a 25 pound bag of flour?
Answer:
45 piesStep-by-step explanation:
25 pound bag contains:
25*3 = 75 cups of flourNumber of pies:
75 : 1 2/3 = 75 : 5/3 = 75 * 3/5 =45 piesI need help on this question please factorise into brackets then solve for x
Answer:
x = 7
Step-by-step explanation:
The difference between the length and width is 3 , then length = x - 3
area (A) of rectangle = length × width
A = x(x - 3) = 28 , distribute parenthesis
x² - 3x = 28 ( subtract 28 from both sides )
x² - 3x - 28 = 0 ← in standard form
(x - 7)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 4 = 0 ⇒ x = - 4
However, x > 0 , then x = 7

Find the area of the circle to the nearest hundredth. (Use 3.14 for π)
options:
452.16 cm2
37.68 cm2
113.04 cm2
18.84 cm2
Answer:
113.04 cm^2
Step-by-step explanation:
To find the area, you do radius squared, multiplied by [tex]\pi[/tex]
Radius is half of the diameter. 12/2 is 6
6^2×3.14=113.1

m/-7<14, what should be done to both sides?
O Divide both sides by 14.
Divide both sides by -7.
O Multiply both sides by 14.
O Multiply both sides by - 7
Answer:
D. Multiply both sides by -7
Step-by-step explanation:
So solving would look like this
m/-7 < 14
m > -2
Remember when multiplying by a negative the sign flips, hope that helps :)

Find the equation of the exponential function represented by the table below:
Answer:
y = 5(4ˣ)
Step-by-step explanation:
Answer:
y = 5 * 4^x
Step-by-step explanation:
exponential functions are of the form
y = ab^x
to find a use point (0, 5)
5 = ab^0
5 = a * 1
a = 5
To find b use any other point
using (1, 20)
20 = 5(b^1)
4 = b^1
b = 4
The equation is
y = 5 * 4^x

Peter wins five sixth of his matches and loses the rest. What is the ratio of wins to losses?
BRAINLIEST
Answer:
5:1
Step-by-step explanation:
5/6 won
1/6 lost
5:1=6
Answer:
5:1
Step-by-step explanation:
Total numbers of match = 6
No. of matches Peter wins = 5
Ratio of wins to lose = 5:(6-5) = 5:1
Please, don't write the answer as 1:5. Because, 5:1 and !:5 both are different so don't be confused.

Sarah had 1 3/4 bags of trail mix. She age 1/2 of a bag. She gave 1/3 of a bag to her friend. She dropped 1/6 of a bag and she was sad. How much trail mix did she had left?
Answer:
3/4 bags of trail mix
Step-by-step explanation:
She ate 1/2 of a bag, she gave 1/3 of a bag, and she dropped 1/6 of a bag. In total she "lost" 1/2+1/3+1/6=1 bag of trail mix. So she has 1 3/4-1=3/4 bags left

Answer:
8
Step-by-step explanation:
4+4 =8
Answer:
y = 8
Step-by-step explanation:
To find this simply you have to put values instead of x and y,
For an example,
If the value of x is 1, you have to put 1 instead of x to the equation to find the value of y,
x = 1,
y = x + 4
y = 1 + 4
y = 5
In the same way, you can find the value of y when the value of x is 4.
x = 4,
y = x + 4
y = 4 + 4
y = 8
Hope this helps you.

Use the graph to determine the
solution (solutions) of the equation
f(x) = 0.
Please help, with explanation
Answer:
-3, 1
Step-by-step explanation:
The vertical scale of the graph is f(x). So, f(x) = 0 is the x-axis. Where the graph crosses the x-axis, the value of f(x) is 0.
The x-axis is labeled on alternate lines. Those labels are sufficient to tell you that each grid line represents one unit. The curve intersects the x-axis 3 units to the left of the vertical axis, at x = -3, at 1 unit to the right of the vertical axis, at x = 1.
The values of x where f(x) = 0 are -3 and 1.

There are 63 students in band. This represents 30% of the grade. How many students are in the entire grade
So, the question is 63 is 30% of what number?
That can translate to the equation
63 = 30% · x or 63 = 0.3x
Divide by 0.3 and you get x = 210.
There are 210 students in band.
Answer:
210 students
Step-by-step explanation:
210 x (3/10) = 63
