Answer:

Step-by-step explanation:

-6x + 3y = -7

to find the x intercept, sub in 0 for y and solve for x

-6x + 3y = -7

-6x + 3(0) = -7

-6x = -7

x = 7/6 <=== ur x intercept is (7/6,0)

to find the y intercept, sub in 0 for x and solve for y

-6x + 3y = -7

-6(0) + 3y = -7

3y = -7

y = -7/3 <=== ur y intercept is (0,-7/3)

Hello there.

There were 196 students that participated in a clean-up event at a nearby lake. this is one fourth of the entire student population. write and solve an equation to find the number of students at this school.

Answer: x is the number of students in the school.
 $\frac{x}{4}$ = 196.
196 x 4 = 784.
Therefore the number of students in this school is 784.

Hope This Helps You!
Good Luck Studying ^-^

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

SpyIntel [72]

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

$3x+8y=55$ -----> equation A

$x+y=15$

$x=15-y$ -----> equation B

Substitute equation B in equation A

$3[15-y]+8y=55$

$45-3y+8y=55$

$5y=55-45$

$5y=10$

$y=2$

Find the value of x

$x=15-y$

$x=15-2=13$

therefore

the answer is

the number of multiple choice question are $13$

the number of free response question are $2$

What is the slope of a line that is perpendicular to the line whose equation is 3x+2y=6 3 x + 2 y = 6 ?

Tanzania [10]

Answer:

The slope of the line perpendicular to the given line is 2/3

Step-by-step explanation:

step 1

Find the slope of the given line

we have

3x+2y=6

isolate the variable y

2y=-3x+6

y=-(3/2)x+3

The slope of the given line is m=-(3/2)

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, their slopes are opposite reciprocal of each other ( the product of their slopes is equal to -1)

m1*m2=-1

we have

m1=-3/2

m2=2/3

therefore

The slope of the line perpendicular to the given line is 2/3

624,612 rounded to the nearest hundred is

Dimas [21]

Answer:

624 600

Step-by-step explanation:

624 612

you have to concentrate at the 1 because because it's at the tens place, if the 1 is not greater than 5 you don't have to do anything. you just have to remove the two numbers before the the number 6 and you so it automatically should be 624 600.

To round a number to the nearest hundredth , look at the next place value to the right (the tens this time). Same deal: If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right.
