Answer x=6 and y=10
Explanation:
Replace each variable in turn with 0 and solve
5x+3y=30 Put zero in place of x and solve for y
5(0)+3y=30
[tex]\frac{3y}{3} =\frac{30}{3}[/tex]
y=10 The y- intercept is 10
5x+3y=30 Put zero in place of y and solve for x
5x+3(0)=30
[tex]\frac{5x}{5} =\frac{30}{5}[/tex]
x=6 The x-intercept is 6

Find the mean of the following set of numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
Enter the answer
Answer:
The mean of the given set of numbers is 3.5
Step-by-step explanation:
We need to find the mean of following numbers:
8.9, 6.1, -4.8, 8.2, 2.7,-0.1
For calculating the mean the formula used is: [tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}[/tex]
Finding sum of numbers:
[tex]Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21[/tex]
Total numbers = 6
So, mean is:
[tex]Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5[/tex]
So, mean of the given set of numbers is 3.5

-3x-5<10 Equations
Answer:
x>-5
Step-by-step explanation:
First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.

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.

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
x + 94° + 23° = 180°
Step 2: Solve for x
Combine like terms: x + 117° = 180°Subtract 117° on both sides: x = 63°Answer: it’s 63
Step-by-step explanation:
All triangles equal 180. So you need to add the angles they give you; so 23+94=117 so then you subtract 117 from 180 which equal 63

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.

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

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
find the value of x.
At a party there are 3 pizzas to share. If each pizza has 8 slices, determine how many pieces each child will receive if 12 kids attend the party. Now what if 8 kids attend?
Answer: your answer is 3
Step-by-step explanation: if you multiply 3 and 8 you get 24 divide that by 8.
The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total number of pizzas at the party = 3 pizzas
The total number of slices in 1 pizza = 8 slices
So , the number of slices in 3 pizzas = 3 x 8 slices
The number of slices in 3 pizzas = 24 slices
Now , the equation will be
The number of children attended the party be = A
The value of A = 12 children
So , the number of pizza slices each child gets = number of slices in 3 pizzas / number of children attended the party
Substituting the values in the equation , we get
Number of pizza slices each child gets = 24 / 12
Number of pizza slices each child gets = 2 slices each
Therefore , if there are 12 children , the number of slices of pizzas each child receives is 2 slices
Now , if the number of children is B = 8
Number of pizza slices each child gets = 24 / 8
Number of pizza slices each child gets = 3 slices each
Therefore , if there are 8 children , the number of slices of pizzas each child receives is 3 slices
Hence , The number of pizzas each kid will receive if there were 12 children was 2 slices each
The number of pizzas each kid will receive if there were 8 children was 3 slices each
