3x + 5y = -7 slope for this equation
Answer:
I have attached the picture of the slope.
Answer:
slope = - [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 5y = - 7 ( subtract 3x from both sides )
5y = - 3x - 7 ( divide all terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x - [tex]\frac{7}{5}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{5}[/tex]

This Diagram Shows a Square (6x-1)cm (4x+6)cm. Find the length of the side of the square. Your final answer must say, Side = ...cm
Given:
Diagram Shows a Square (6x-1)cm (4x+6)cm.
To find:
The length of the side of the square.
Solution:
We know that, all sides of a square are equal. So,
[tex]6x-1=4x+6[/tex]
[tex]6x-4x=1+6[/tex]
[tex]2x=7[/tex]
Divide both sides by 2.
[tex]x=\dfrac{7}{2}[/tex]
[tex]x=3.5[/tex]
Now, the side of the square is
[tex]Side=6x-1[/tex]
[tex]Side=6(3.5)-1[/tex]
[tex]Side=21-1[/tex]
[tex]Side=20\text{ cm}[/tex]
Therefore, the length of the side of the square = 20 cm.
Answer:
Given:

What is the decimal for the fraction 22/4
The decimal for this fraction is 5.5
Answer:
The decimal for the fraction is 5.5.
Step-by-step explanation:
Between 20/4 and 24/4, you can safely assume that the fraction provided is between 5 and 6 which makes part of your answer as a whole number 5. Since 22/4 is exactly between the fractions mentioned above, it is safe to assume that the decimal is 5.5 with .5 being half of the number.

The ratio of the numerator to the denominator of a fraction is 2 to 3. If both the numerator and the denominator are increased by 2, the fraction becomes . What is the original fraction?
Answer:
a) If both the numerator and the denominator are increased by 2, the fraction becomes?
= 4/5
b) What is the original fraction?
= 2/3
Step-by-step explanation:
The ratio of the numerator to the denominator of a fraction is 2 to 3.
a) If both the numerator and the denominator are increased by 2, the fraction becomes .
2:3 = 2/3
We are told that both numerator and denominator are increased by 2, hence:
2 + 2/3 + 2
= 4/5
b) What is the original fraction?
The ratio of the numerator to the denominator of a fraction is 2 to 3.
Hence, the original fraction is:
2:3 = 2/3

which recursive formula can be used to represent the sequence 2,5,8,11,14,..
a. a1=2 an-1=an+3
b. a1=0 an=an-1+3
c. a1=2 an=an-1-3
d. a1=2 an=an-1+3
The recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.
SequenceA sequence is an ordered set of numbers that frequently maintain a pattern.
How to find a recursive formula that is used to represent the given sequence?The given sequence is 2,5,8,11,14,..
The first term is 2.
So, a(1)=2
The common difference is (5-2), that is 3.
So, the recursive formula is a(n)=a(n-1)+3
Therefore, the recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.
Thus, the correct option is (d)

A certain cookie recipe calls for 3 cups of flour to make one batch of cookies. Which
of the following graphs BEST represents the relationship between the amount of
flour and the number of batches of cookies that can be made using this recipe?
Answer:
the answer is the one similar to the one highlighted in purple, but the line should go through the points (3,1), (6,2), (9,3), (12,4)... so on and so forth
Step-by-step explanation:
We want to see which graph represents the relationship between the number of cups of flour and the number of batches of cookies that can be made with the recipe. The graph can be seen at the end.
So, we know that for every 3 cups of flour, we can make 1 batch of flour.
This relation can be written as:
y = (1/3cups)*x
Where y is the number of batches of cookies that you get, and x is the number of cups of flour that you use.
The graph of this line can be seen in the image below:
You can notice that neither of the two shown graphs coincides with this, so the correct option is not shown.

4(3x + 2) =16x + 7 -4x + 1
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3x+2)=16x+7−4x+1
(4)(3x)+(4)(2)=16x+7+−4x+1(Distribute)
12x+8=16x+7+−4x+1
12x+8=(16x+−4x)+(7+1)(Combine Like Terms)
12x+8=12x+8
12x+8=12x+8
Step 2: Subtract 12x from both sides.
12x+8−12x=12x+8−12x
8=8
Step 3: Subtract 8 from both sides.

When you multiply the following binomials, what is the linear term (the term with x)?
(X+3) (X-5)
Answer:
We conclude that 2x is the linear term with x.
Step-by-step explanation:
Given the expression
[tex]\left(x+3\right)\left(x-5\right)[/tex]
Multiplying the binomials
Apply FOIL method:
[tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
[tex]\left(x+3\right)\left(x-5\right)=xx+x\left(-5\right)+3x+3\left(-5\right)[/tex]
Apply +(-) = - rule
[tex]=xx-5x+3x-3\cdot \:5[/tex]
simplify
[tex]=x^2-2x-15[/tex]
Here, 2x is the linear term with x.
It is called a linear term because the exponent of the variable is raised to the power of 1.
In other words, the degree of the linear term is 1.
Therefore, we conclude that 2x is the linear term with x.
