Answer: C:10
Step-by-step explanation:
Equation of a line passes through (a,b) and (c,d) :
[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]
Equation of line passes through A(-2,8) and B(4,14) will be :
[tex]y-8=\dfrac{14-8}{4-(-2)}(x-(-2))\\\\\Rightarrow\ y-8= \dfrac{6}{6}(x+2)[/tex]
[tex]\Rightarrow\ y-8=x+2\\\\\Rightarrow\ y= x+2+8\\\\\Rightarrow\ y=x+10[/tex]
For y-intercept , put x= 0 , we get y= 10
So, the y-intercept = 10
Thus , correct option = C:10

Answer:
y = $19.50
x = $17.17
z = $20.67
Step-by-step explanation:
Notice that $13.50 of $22.50 is 60% (in math decimal form 0.6). The same is true for $16.20 of $27.00. Therefore, the value of y is going to be :
0.6 * $32.50 = $19.50
We notice as well that the added taxes to the discount price $13.50 is:
14.31 - 13.5 = $0.81, which at a time is a percent of the discounted sales price. Such percentage is calculated as shown below:
0.81/13.5 = 0.06 (or 6%)
we can then add 0.06 * 16.20 = 0.972 to 16.20 to find the total price "x"that includes tax:
x = $16.20 + $0.97 = $17.17
And we do something similar to find z:
z = $20.67

Shelly deposited $8,000 into a savings
account that earns 4% simple interest.
How much interest did she earn after
three years?
Answer:
Shelly earned $8,960 in interest.
Step-by-step explanation:
The formula for simple interest is A=P(1+rt). For this problem, the equation is A=8,000(1+0.04x3). 8,000 is the initial balance, 0.04 is the annual interest rate, and 3 is the time in years. Following the order of operations, 0.04 multiplied by 3 is 0.12. 0.12 plus 1 is 1.12. 8,000 multiplied by 1.12 is 8,960.
Answer:
£960
Step-by-step explanation:
So you start of by calculating the interest for one year.
8,000 × 0.04 = 320
Because the interest rate is 4% you will write it as 0.04
And because it is simple interest, you will need to multiply 320 by 3 to get the amount of interest she will get after 3 years.
320 × 3 = 960
If you wanted the total amount of money she would have after receving the interest, you just have to add 960 to the starting amount of 8,000.
8,000 + 960 = 8,960
In this, you are assuming that she doesn't take any money out or put any money in for those 3 years.
I think that's right anyway.

you are rolling a die number 1-6. What is the theoretical probability that you roll a 6?
Answer:
16.7 percent
So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

is 4(x+1) - 3 and 4x + 1 equivalent and why ??
Step-by-step explanation:
Hey there!
Given;
4(X+1) -3 and 4x+1.
No, they are equivalent.
Reason:
Solving 1st expression.
4(x+1) = 4x + 4 - 3
Now, next expression is: 4x+1.
So, 4x + 4 = 4x+1
So, they are equivalent to eachother.

Step-by-step explanation:
f, your friends lunch
f + 3, your lunch
f + f + 3 = 19
2f + 3 = 19

Peter has a 25 acre field. He 20.5 acres with sweet corn . What fraction of his field does Peter plant with sweet corn
Answer:
82%
Step-by-step explanation:
Multiply 25*4 to get 100.
Then multiply 20.5*4 because what you do to one side you have to do for the other.
You end up with 0.82 or 82%
Based on the length of the field and the amount of the field that was planted the fraction of the field planted is 4.1/5.
The field has a length of 25 acres and Peter plants in 20.5 acres of them.
The fraction that is planted is:
= Amount of field planted on / Total area of field
Solving will give:
= 20.5 / 25
Take to the simplest form by dividing both by 5:
= 4.1 / 5
In conclusion, the fraction planted on is 4.1/ 5.

Answer:

0.3
Step-by-step explanation:
Brainliest?
We want to rewrite the given expression as a square of a monomial. We will get:
0.09*a^2 = (0.3*a)^2
So we have the expression:
0.09*a^2
We want to write this as a square of a monomial like:
(c*a)^2 = 0.09*a^2
Basically, we must find a number c such that:
c^2 = 0.09
c = √(0.09) = 0.3
Then the monomial is:
0.3*a
And we can rewrite the given expression as:
(0.3*a)^2
