Step-by-step explanation:
The x-intercept is the value of x when y is 0
So you need to substitute:
0 = 4x + 7
-7 = 4x
-7/4 = x
(-7/4,0)
Similarly, the y-intercept is the value of y when x is 0
So:
y = 4x + 7
y = 4(0) + 7
y = 7
(0,7)

an arithmetic sequence has sixth term 15 and ninth term 16. Find its common difference. determine which term has value 22.
Answers
Answer:
The 27th term is 22Step-by-step explanation:
Let the first term is a and common difference is d.
The nth term is:
aₙ = a + (n - 1)dWe have:
a₆ = 15a₉ = 16The difference of these terms is:
(a + 8d) - (a + 5d) = 16 - 153d = 1d = 1/3Then the first term is:
a + 5*1/3 = 15a = 15 - 5/3 = 13 1/3The nth term equation is:
aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13If the nth term is 22, find n:
1/3n + 13 = 221/3n = 22 - 131/3n = 9n = 9*3n = 27Find the product of 6b(2 over 3b).

The chess clubs at school decides to give $400 to a charity at Christmas time. If the chess club raised $1,000 fund raising. What percent of the fund raiser did they donate to charity
Answers
Answer: 40%
Step-by-step explanation:
To find the percent, divide the amount donated by the full amount of money raised. 400/1000 = 0.4.
Now to make this into a percentage, multiply the answer by 100. 0.4 * 100 = 40.
Percent of the fund raiser did they donate to charity 40%
What is percentage ?In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Percentages have no dimension. Hence it is called a dimensionless number. If we say, 50% of a number, then it means 50 per cent of its whole.
To find the percent,
divide the amount donated by the full amount of money raised. 400/1000 = 0.4.
Now to make this into a percentage,
multiply the answer by 100. 0.4 * 100 = 40.
