Why do we use standard form?
Answer:
Standard Form is useful because a lot of times as it's helpful to find the x and y intercepts. And it also gets to be useful once you start studying quadratics which is when you have x squared. However most of the time people like to use equations that are either in point slope form or slope intercept form.
Step-by-step explanation:
The diagram shows triangle ABC with AB perpendicular to BC. A is the point (-6, 6) and B is the point (-5, 2). The gradient of AC is - 2/9 Find the coordinates of C.
WILL MARK BRAINLIEST
Answer:
C (3, 4 )
Step-by-step explanation:
slope is calculated as
m = [tex]\frac{vertical}{horizontal}[/tex] between 2 points on a line
m = - [tex]\frac{2}{9}[/tex]
means a change of - 2 in the vertical and + 9 in the horizontal
A (- 6, 6 ) → (- 6 + 9, 6 - 2 ) → (3, 4 )
Coordinates of C (3, 4 )
there are 16 boysin an english class of 28 students. the ratio of boys to the total numbers of students in this class is typical of the whole school. there are 476 students in the school. about how many are boys.
Answer: 272 boys
Step-by-step explanation:
16:28 can be simplified
4:7
Divide the total # of students by 7 then multiply it by 4
476/7 = 68
68 x 4 = 272
I agree with the other answer
Answer: 272 boys
Step-by-step explanation:
16:28 can be simplified
4:7
Divide the total # of students by 7 then multiply it by 4
476/7 = 68
68 x 4 = 272

is this correct? responding due to annoying bots.
Answer:
Yep, they are all correct
Step-by-step explanation:
I have not seen your previous post but am assuming you want me to check
1. Number one is correct, when we simplify the both of them, they are correct pr the same value. 1.5 = 1.5
2. Number two is also correct 38=38
3. And number three is also correct 2.4 = 2.4
All in all, all of them are correct, good job :)

4x - 9 = 2x + 7.
I need correct explanation with please.
Answer:
8
Step-by-step explanation:
4x - 9 = 2x + 7
4x - 2x = 7 + 9
2x = 16
x = 16 / 2
x = 8
Here, we are given with an equation in which we are given with some constants and two same variables x. We are said that the LHS and RHS are equal to each other. We are asked to find the value of the variable x. To find the value of x, we use an other concept which helps us to find the value of x and also to verify our answer. This concept is called as the transposition method. While using this method, the sign of the appropriate number or variable changes. We use this method to shift the numbers and variables on two separate sides. We can also verify our answer at the end of our answer by verification method. So, let's solve!!
[tex]\:[/tex]
➤ Solution :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Shift the variable value to LHS and the constant value to RHS, changing it's sign.
[tex]{\sf \leadsto 4x - 2x = 7 + 9}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 2x = 16}[/tex]
Shift the number 2 from LHS to RHS.
[tex]{\sf \leadsto x = \dfrac{16}{2}}[/tex]
Simplify the fraction to find the value of x.
[tex]{\sf \leadsto x = 8}[/tex]
[tex]\:[/tex]
[tex]{\red{\underline{\boxed{\bf So, \: the \: value \: of \: x \: is \: 8.}}}}[/tex]
━━━━━━━━━━━━━━━━━━━━━━━
Verification :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Substitute the value of x.
[tex]{\sf \leadsto 4(8) - 9 = 2(8) + 7}[/tex]
Multiply the numbers in the bracket.
[tex]{\sf \leadsto 32 - 9 = 16 + 7}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 23 = 23}[/tex]
So,
[tex]{\sf \leadsto LHS = RHS}[/tex]

Write a function g whose graph is a translation 3 units to the left of the graph of f.
Answer:
f(x) = (x + 3)
Step-by-step explanation:
when it's in the parentheses, it's the opposite so in this if it's saying 3 units to the left, it would be subtracting or negative so to make it the opposite u do x + 3 in parentheses

-325
75
75 ÷ 15 = 5
It is 5 pounds over the 50 pound limit.
In evaluating the limits of rational functions, the numerator and the denominator was found out to be both equal to zero, what does it mean?
Answer:
If only numerator found as zero the answer would be zero. If only denominator found as zero the answer is undefined. In your situation both are zero. But, when denominator becomes zero the answer always be undefined. Therefore, your answer is undefined when both numerator and denominator are zeros.
Mrs. Castro left her parents' house in the province and drove home.
After driving for 3 hours, she was 90 km from home, and after
5 hours, she was 25 km from home. Assuming that the distance from
home and the number of hours driving form a linear relationship,
how long did it take Mrs, Castro to drive from her parents' house
to her home? How far was Mrs, Castro from home after driving
6 hours? How long had Mrs. Castro been driving when she was
50 km from home?
Answer:
Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.
