Find all possible values of b such that 4x^2+bx+3 can be factored?
Answer:13,7,8 but if there’s an answer choice go with 7,8
Step-by-step explanation: Assuming b is an integer, we first look at factors of 4, being 1 and 4 or 2 and 2. The factors of 3 are 1 and 3 only. So the factorisation possibilities are (x+3)(4x+1), (4x+3)(x+1) and (2x+1)(2x+3).
Expanding these we get: 4x²+13x+3, 4x²+7x+3 and 4x²+8x+3, giving values of b=13, 7 and 8
The possible values of b in the given polynomial are 7, 8 or 13.
What is a polynomial?In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer powers of variables.
Given is a polynomial, 4x²+bx+3, we need to find all possible values of b such that 4x²+bx+3 can be factored.
4x²+bx+3
4×3=2×2×3
2×2×3 = 2×6 and 2+6 = 8
2×2×3 = 4×3 and 4+3 = 7
2×2×3 = 12×1 and 12+1 = 13
b=7, b=8, and b=13
4x²+7x+3 = (4x+3) (x+1)
4x²+8x+3 = (2x+1) (2x+3)
4x²+13x+3 = (4x+1) (x+3)
Hence, the possible values of b in the given polynomial are 7, 8 or 13.

Dave is making cookies.
He mixes flour, butter and sugar in the ratio 6:4:1
Dave uses 160 grams of butter.
Work out how much flour and sugar Dave uses.
Answer: 240 grams of flour and 40 grams of sugar.
Step-by-step explanation: I used the rule of three to calculate the values for the flour and sugar. The common ratio that these numbers have would
be 40.
Reasoning: If the ratio is 6:4:1, then you can apply it as a rule of three. If 160 relates to 4, then x (the value of flour) will relate to 6. 160/4 = x/6, cross multiply, and x = 240. The amount of flour is 240 grams. Using the same logic, you can set another rule for the amount of sugar (represented by variable s); 160/4 = s/1. Cross multiply, and s = 40. The amount of sugar is 40 grams.

Answer:
All real solutions
Step-by-step explanation:
5w - 15 < 5w + 20
subtract 5w from both sides
-15 < 20
since it is true and there are no variables left. all real solutions will make this true
Answer:
w < w + 7
Step-by-step explanation:
5w-15 < 5w+20
divide all by 5 =
w < w + 7
Write a linear function f with the values f(-4) = 0 and f (4) = 2.
Answer:
y + (1/4)(x + 4)
Step-by-step explanation:
One point on the graph is (-4, 0); another is (4, 2).
The change in x from the first point to the second is 8; this is the 'run.'
The change in y is 2 (which is 2 - 0). This is the 'rise.'
Thus, the slope of the line is m = rise / run = 2/8 = 1/4
Let's use the point-slope form of the equation of a straight line:
y - k = m(x - h). Substituting 0 for k and -4 for h, we get:
y - 0 = (1/4)(x + 4), or
y + (1/4)(x + 4)

which linear function represent the table?
Answer:
Step-by-step explanation:So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function. This rate of change is called the slope.Mar 9, 2011
Natalie and John are both saving coins in jars for a rainy day. Natalie currently has 1 1/8 jars of coins, and John has 9/14 of a jar of coins. If John gets all his coins to Natalie, how many jars of coins would she have all together?
Answer:
Natalie will have [tex]1\frac{43}{56}[/tex] jars of coins all together after receiving John's coins.
Step-by-step explanation:
Given that:
Coins Natalie have = [tex]1\frac{1}{8}[/tex] jars of coins
Coins John have = [tex]\frac{9}{14}[/tex] jars of coins
When John will give all his coins to Natalie.
Total coins Natalie have = Her coins + John's coins
Total coins Natalie have = [tex]1\frac{1}{8}+\frac{9}{14}[/tex]
Total coins = [tex]\frac{9}{8}+\frac{9}{14}[/tex]
Total coins =[tex]\frac{63+36}{56}=\frac{99}{56}[/tex]
Total coins = [tex]1\frac{43}{56}[/tex]
Hence,
Natalie will have [tex]1\frac{43}{56}[/tex] jars of coins all together after receiving John's coins.

find x if 20% of x equals 12% of (x + 20)
Answer:
x = 30
Step-by-step explanation:
We have to find x
Given that:
20% of x = 12 % of (x +20)
This can be written as:
0.2(x) = 0.12 (x + 20)
0.2x = 0.12x + 2.4
Subtracting 0.12x from both sides we get:
0.2x - 0.12x = 0.12x - 0.12x + 2.4
0.08x = 2.4
Dividing both sides by x we get:
0.08/0.08x = 2.4/0.08
x = 30
Answer:
x = 30
Step-by-step explanation:
Set up an equation:
0.2x = 0.12(x + 20)
Distribute 0.12 and solve for x:
0.2x = 0.12x + 2.4
0.08x = 2.4
x = 30
So, the answer is x = 30

The quadratic [tex]3x^2+4x-9[/tex] has two real roots. What is the sum of the squares of these roots? Express your answer as a common fraction in lowest terms.
Answer:
70/9
Step-by-step explanation:
We have the quadratic:
[tex]3x^2+4x-9[/tex]
So, let’s find the roots of the quadratic. We will set the expression equal to 0:
[tex]3x^2+4x-9=0[/tex]
Testing for factors, we can see that our quadratic isn’t factorable.
So, we can use the Quadratic Formula. The quadratic formula is given by:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case:
[tex]a=3, b=4,\text{ and } c=-9[/tex]
Therefore, by substitution:
[tex]\displaystyle x=\frac{-(4)\pm\sqrt{(4)^2-4(3)(-9)}}{2(3)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{-4\pm\sqrt{124}}{6}[/tex]
Simplify the square root:
[tex]\sqrt{124}=\sqrt{4\cdot31}=2\sqrt{31}[/tex]
Hence:
[tex]\displaystyle x=\frac{-4\pm2\sqrt{31}}{6}[/tex]
Reduce:
[tex]\displaystyle x=\frac{-2\pm\sqrt{31}}{3}[/tex]
So, our roots are:
[tex]\displaystyle x_1=\frac{-2+\sqrt{31}}{3}, x_2=\frac{-2-\sqrt{31}}{3}[/tex]
We want to find the sum of the squares of our two roots. So, let’s square each term:
[tex]\displaystyle (x_1)^2=\Big(\frac{-2+\sqrt{31}}{3}\Big)^2[/tex]
Square. For the numerator, we can use the perfect square trinomial patten where:
[tex](a+b)^2=(a^2+2ab+b^2)[/tex]
Therefore:
[tex]\displaystyle (x_1)^2=\Big(\frac{(-2)^2+2(-2)(\sqrt{31})+(\sqrt{31})^2}{9}\Big)[/tex]
Simplify:
[tex]\displaystyle (x_1)^2=\frac{35-4\sqrt{31}}{9}[/tex]
Similarly, for the second root, we will have:
[tex]\displaystyle (x_2)^2=\Big(\frac{-2-\sqrt{31}}{3}\Big)^2[/tex]
So:
[tex]\displaystyle (x_2)^2=\Big(\frac{(-2)^2+2(-2)(-\sqrt{31})+(-\sqrt{31})^2}{9}\Big)[/tex]
Simplify:
[tex]\displaystyle (x_2)^2=\frac{35+4\sqrt{31}}{9}[/tex]
Therefore, our sum will be:
[tex]\displaystyle (x_1)^2+(x_2)^2\\\\ \begin{aligned} &=\frac{35-4\sqrt{31}}{9}+\frac{35+4\sqrt{31}}{9}\\&=\frac{35-4\sqrt{31}+35+4\sqrt{31}}{9}\\&=\frac{70}{9}\end{aligned}[/tex]
Therefore, our final answer is 70/9.
