(3x + 1) (x - 2)
= 3x(x - 2) + 1(x - 2)
= 3x² - 6x + x - 2
= 3x² - 5x - 2
At which point do the two equations
[tex]3x + 5y = y + 4x[/tex]
and
[tex]y = {x}^{2} [/tex]
intersect?
The lines intersect at two places.
They intersect at approximately (-2,8) and (2,3)
Looking at the choices they would be at (1.8,3.2) and (-2.8,7.8)
The answer is D. Both A and B.
Explain how to find the y-intercept on a graph.
Answer:
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Vectors a, b, c, d and e are drawn on an isometric grid.
a
Write each of the vectors c, d and e
in terms of a and/or b.
Give each answer in its simplest
form
Answer:
c= 3a
d= a+b
e= a-b
A resultant vector is given by the sum of the component vectors
The correct options are;
c = 3·a
d = a + b
e = a - b
The reasons why the above options are correct are as follows:
Required:
To write the vectors c, d, and e in terms of a and/or b
Solution:
The vector c comprises of three horizontal segments each of length a, therefore, we have;
c = 3·a
The vector d comprises of the vectors a followed by the vector b, therefore, we have;
d = a + b
The vector e comprises of the re verse of the vector b (which is -b) followed by the vector a to give;
e = a - b

7 people will equally split 258.2 acres of land. To the nearest tenth of an acre, how much land will each person get
Answer:
Each person will get 36.9 acres of land.
Step-by-step explanation:
Given that:
Total land = 258.2 acres
7 people will equally split the land between them, therefore, we will divide the total land by total number of people to calculate the share of each person.
Share of each person = [tex]\frac{258.2}{7}[/tex]
Share of each person = 36.88 acres
Rounding to the nearest tenth,
Share of each person = 36.9 acres
Hence,
Each person will get 36.9 acres of land.

lily likes to collect records. Last year she had 4 records in her collection. Now she has 7 records. What is the percent increase of her collection?
Answer:
75% increase
Step-by-step explanation:
First we need to figure out how many new records she got this year...
7-4 = 3 new records.
Now, we need to know how many times 4 goes into 100%....
100 ÷ 4 = 25%
This tells us that a single record this year is a 25% increase.
Now, we multiply 25% by 3 to get 75% as our final answer

3(x+5) = 7x + 12 - 4x + 3.
Answer:
Infinitely many solutions
Step-by-step explanation:
3(x+5) = 7x + 12 - 4x + 3
3x + 15 = 7x + 12 - 4x + 3
3x + 15 = 3x + 12 + 3
3x + 15 = 3x + 15
They are the same equation, therefore there are infinitely many solutions.

Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.
This gives you: 1 - 4 - 7 + 10 = 0.
Because 0 = 0 is a true statement, you know that x = 1 is a solution.

When multiplying 1,729 times 308, Clayton got a product of 53,253. Without
calculating, does his product seem reasonable?
Answer:
Well, let's try and estimate it! Let's say.....1,700 times 300. or even to simplify it a bit more 2000 times 300.
Step-by-step explanation:
First, 1,700 times 300 is 510,000. Since you already know that you can figure out that it's already not true.
2000 times 300 is 600000. So that also comes into context.

The percentage of pizza Marissa ate was 37.5 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the percentage of pizza Marissa ate be = A
Let the total number of slices in the pizza be = 16 slices
Let the number of slices of pizza Marissa ate be = 6 slices
So , the equation will be
The percentage of pizza Marissa ate A = ( number of slices of pizza Marissa ate / total number of slices in the pizza ) x 100
On substituting the values in the equation , we get
The percentage of pizza Marissa ate A = ( 6 / 16 ) x 100
The percentage of pizza Marissa ate A = ( 3 / 8 ) x 100
The percentage of pizza Marissa ate A = 0.375 x 100
The percentage of pizza Marissa ate A = 37.5 %
Therefore , the value of A is 37.5 %
Hence , The percentage of pizza Marissa ate was 37.5 %
