Question: -3x – 10 = 32

Answers

Answer:

x = -14

Step-by-step explanation:

The first thing you are trying to do is get the x alone. so first you will look at 10 and do the opposite of the sign that you have. So you would take the -10 and make it +10. you would solve -10 + 10 and 32 + 10 because whatever you do to one side you do to the other. -10 +10= 0 and 32+10 = 42. Your equation now is -3x=42. we do not put -3x+0=42 because zero does not have a value. From here we would look at the -3x and do the opposite sign, which means dividing. whenever a number is next to x or any variable it is multiplication. For example, 7x is the same as 7*x. The opposite of multiplication is division. so we would do -3x/-3. We do 42/-3 because whatever we do to one side we do to the other. On the left side we are left with x then you add the equal sign and the quotient of 42/-3.

Answer: x = -14

I drive at 55 miles per hour, and my trip will takr 5 hours. Proportional or non proportional

Answers

Answer:

Proportional

Step-by-step explanation:

Here, we want to know if the distance at the given time will be proportional

What we will do here is to simply divide the distance by the time

Mathematically, that will be 55 miles/ 5 hours = 11 miles / hour

So this means that in an hour, 11 miles will be traveled

This expression is proportional

There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?

Answers

I’m pretty sure it decreased, apologies if I got this wrong

The sum of participants last year was 44 students, but this year was only 37.80 participants.

There is an increase in total participants.

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

number of boys = 28

Number of girls = 16

Total participants = 28 + 16 = 44

Now, there is decrease in number of boys by 8%

= 28- 8% x 28

=28- 8/100 x 28

=28 - 0.08*28

=28 -2.24

= 25.76

and, there is 19% increase in number of girls

=16 + 0.19 x 16

=16 + 3.04

=19.04

So, total participants = 25.76 + 19.04

= 44.8

Hence, there is an increase in total participants.

At the supermarket, you can fill your own honey bear container. A customer buys 12 oz of honey for $5.40.
How much does honey cost per ounce?
How much honey can you buy per dollar? Round to the nearest hundredth.

Answers

Answer: a. $0.45; b. 2.22 oz

Step-by-step explanation:

From the question, we are informed that acustomer buys 12 oz of honey for $5.40.

a. How much does honey cost per ounce?

To calculate this, we divide $5.40 by 12oz. This will be:

= $5.40/12

= $0.45

b. How much honey can you buy per dollar?

Since 1 ounce cost $0.45, the number of honey that can be bought for $1 will be:

= $1/$0.45

= 2.22 oz

find the equation of the line that passes through a and b

Answers

Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line

8. A line passes through the points (0-2) and (0,5). Is it possible to write an equation of the line in
slope-intercept form? Justify your answer.

Answers

Answer: No

Step-by-step explanation:

There is no slope

It is not possible to write the equation of the line passing through (0, -2) and (0, 5), because slope is not defined.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given that a line passes through two points (0, -2) and (0, 5).

Both the points are on Y axis.

Therefore the line is along the Y axis.

Slope of a line along the Y axis is not defined since the Y axis is making 90° with the X axis and tan 90° is the slope, which is not defined.

Or in other words, taking the given points,

slope = change in y coordinates / change in x coordinates

= (5 - -2) / (0 - 0)

= 7 / 0, not defined.

Hence the equation of the line along the Y axis cannot be written in the slope intercept form as the slope is undefined.
