hello : 2x+5y= - 6
1) the x-intercept when y=0 : 2x+5(0)= -6
means : 2x=-6 so : x=-6/2 = -3
2) the y-intercept when x=0 : 2(0)+5y= -6
means : 5y=-6 so : x=-6/5

How do you solve this question? With a step by step explanation please!
[tex]\frac{1}{4}x + 2 = -3 + \frac{1}{2} x[/tex]
First, we will take [tex]\frac{1}{4}[/tex]x to the right hand side of the equation, and -3 to the left hand side. In doing so, their signs will change (that is, they will be subtracted from the side that they are moved to).
2 -(-3) = [tex]\frac{1}{2} x - \frac{1}{4} x[/tex]
2 + 3 = [tex]\frac{1}{4}[/tex]x
[tex]\frac{1}{4} x = 5[/tex]
Now, we will multiply both sides by 4, so as to find x.
[tex]\frac{1}{4} x[/tex] x 4 = 5 x 4
x = 20
Therefore, x = 20.

Step-by-step explanation:
factor using the box method or quadratic formula.
Answer:
(x - 9)(x + 1)
Step-by-step explanation:
Given
x² - 8x - 9
Consider the factors of the constant term (- 9) which sum to give the coefficient of the x- term (- 8)
The factors are - 9 and + 1, since
- 9 × 1 = - 9 and - 9 + 1 = - 8, thus
x² - 8x - 9 = (x - 9)(x + 1)

Zech deposited $5,600 in an account, which compounded 1.9 percent quarterly, and left it there for 10 years. What was the amount in the account at the end of 10 years? Round to the nearest dollar.
Answer:
$6769
Step-by-step explanation:
To calculate the amount, we make use of the compound interest formula
A = P(1+r/n)^nt
where A is the amount which we are to calculate
P is the amount deposited which is $5,600
r is the rate which is 1.9% or 1.9/100 = 0.019
t is the number of years = 10
n is the number of times the interest is compounded per year which is 4(quarterly means every 3 months and there are 4 quarters in a year)
Plugging all these values, we have
A = 5,600(1+ 0.019/4)^40
A = 5,600( 1 + 0.00475)^40
A = 5,600(1.00475)^40
A = $6768.75
Which is $6769 to the nearest dollars

Answer:
The only statement that is NOT true is option A.
- If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
Step-by-step explanation:
Complete Question
Ellen is opening. Cookie shop eat a local middle school . She randomly surgery’s students to determine The types of cookies they would buy at the cookie shop the results of the surveys are below based on the survey. Which statement is not true?
Cookie Survey
Type of Cookie | Number of Students
Chocolate Chip | 25
Oatmeal Raisins | 15
Peanut Butter | 22
Sugar | 18
A) If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
B) 22½% of the students surveyed would buy a sugar cookie.
C) If 240 students were to purchase a cookie from the store, approximately 66 students will purchase a peanut butter cookie.
D) Half of the students prefer chocolate chips or oatmeal raisin cookies.
Solution
First of, we obtain the proportion or percentages of students surveyed that buy each type of cookie.
Each of that is the number of students that buy the type of cookie in the sample divided by the Total number of students sampled.
Total number of students sampled = 25 + 15 + 22 + 18 = 80
Type of Cookie | N | proportion | %
Chocolate Chip | 25 | 0.3125 | 31.25%
Oatmeal Raisins | 15 | 0.1875 | 18.75%
Peanut Butter | 22 | 0.2750 | 27.50%
Sugar | 18 | 0.2250 | 22.50%
Now, taking the statements one by one
A) If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
Proportion of students that buy sugar cookie in the sample = 0.225
Number of students that will buy sugar cookie amongst 160 students = np = 160 × 0.225 = 36 students.
This statement is false, that is, NOT true.
B) 22½% of the students surveyed would buy a sugar cookie.
From the table, 22.5% of the students surveyed bought a sugar cookie. Hence, no matter the number of students, the percentage of students that will buy a sugar cookie will approximately be 22.5%.
This statement is True.
C) If 240 students were to purchase a cookie from the store, approximately 66 students will purchase a peanut butter cookie.
Proportion of students that buy peanut butter cookie in the sample = 0.275
Number of students that will buy peanut butter cookie amongst 240 students = np = 240 × 0.275 = 66 students.
This statement is true.
D) Half of the students prefer chocolate chips or oatmeal raisin cookies.
Proportion of students that buy chocolate chips or oatmeal raisin cookies in the sample = 0.3125 + 0.1875 = 0.50
0.50 is half of the distribution.
Hence, this statement too, is True.

The total finance charge over the course of his loan is $2071.20.
It is required to find the total finance charge.
What is simple & compound interest?Simple Interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time. Compound Interest can be defined as when the sum principal amount exceeds the due date for payment along with the rate of interest, for a period of time. Formula. S.I. = (P × T × R) ⁄ 100.
Given that:
Loan= $15,000
The table tells you that Bob's monthly payment on a 4-year loan at 6.5% will be 23.71 per thousand borrowed.
The sum of those 48 payments is ...
=48 × $23.71 =
=$1138.08
That means, Bob pays $138.08 in total finance charge for each $1000 he borrows. He is borrowing 15 times $1000.
so his total finance charge will be
= 15 × $138.08
= $2071.20
Therefore, the total finance charge over the course of his loan is $2071.20.

What is the volume of a cube with a side length of 5 cm?
A) 10 cm3
B) 15 cm3
C) 25 cm3
D) 125 cm3
Answer:
D. 125 cm³
Step-by-step explanation:
Volume is how much space an object takes up.
The volume of a cube is denoted by: V = s³, where s is the side length of the cube. Here, we see that s = 5, so plug this into the formula:
V = s³
V = 5³ = 5 * 5 * 5 = 125
The answer is thus D.

180/9 x 10^-5
IN SCIENTIFIC NOTATION
Answer:
2*10^-4
Step-by-step explanation:
Answer:
2.0x10^6
Step-by-step explanation:
First, let's change the number in the numerator into scientific notation.
180/ 9.0x 10^-5 = 1.80x10^2/ 9.0x10^-5
Start by collecting the significance and exponents.
1.80X10^2/ 9.0x10^-5 = 1.80/ 9.0x 10^2/10^-5
Then divide each term separately. When dividing exponents with the same base, subtract their power.
=0.20x10^2-(-5) =0.20x 10^7
To write the answer correctly in scientific notation, the first number needs to be between 1 and 10. In this case, we need to move the decimal one position to the right without changing the value of our answer.
We can use the fact that 0.20 is the same as 2.0/10, or 2.0x 10^-1
=2.0x10^-1x 10^7
=2.0x 10^-1+7
=2.0x 10^6

WHAT IS THE PERIMETER?
The perimeter is just the distance around a shape. If you put a fence around a field, the length of all of the fencing is the perimeter.
-------------------------------------------------------------------
WHAT IS AN ISOSCELES TRIANGLE?
An isosceles triangle is a triangle that has at least two sides that have the same length! In our triangle, we have two sides that have the value of a, so that makes it isosceles!
-------------------------------------------------------------------
THE SOLUTION
In our problem, we want to find the perimeter of this triangle in terms of a and c. When we say in terms of, it just means that our answer will include a and c instead of finding a number value.
The perimeter is the sum of each of these sides. This means that the perimeter is a+a+c, which is also 2a+c.
Therefore, the perimeter of this isosceles triangle is 2a+c.

A girl and a puppy are 850 feet apart when they start running towards each other. The girl runs at a speed of 8 feet per second, and the puppy runs at a speed of 7 feet per second. How soon will they meet?
Answer:
time taken = 850/(8+7) =56.6 second
Answer:
The answer is: 56 2/3
Step-by-step explanation:
First add up the amount of feet they run all together every second. 8+7=15 feet/second. You have to find the total amount of seconds for them to meet so you divide. 850 divided 15 equals 56 2/3 seconds. That's your answer.
