Answer:4/3
Step-by-step explanation:
Use the slope formula
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{1-(-3)}{1-(-2)} = 4/3[/tex]
Answer:
The slope of a line that passes through (-2, -3) and (1, 1) is 4/3.
Step-by-step explanation:
Here's the required formula to find slope line :
[tex]\star{\underline{\boxed{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}}[/tex]
Here, we have provided :
[tex]\begin{gathered} \footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf y_2 = 1\\& \sf y_1 = - 3\\ & \sf x_2 = 1\\ & \sf x_1 = - 2\end{cases} \end{gathered}[/tex]
Substituting the values in the formula to find slope line :
[tex] \begin{gathered} \qquad{\longrightarrow{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{(1) - ( - 3)}{1 - ( - 2)}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{1 + 3}{1 + 2}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{4}{3}}}} \\ \\ \qquad{\star{\underline{\boxed{\frak{m = \dfrac{4}{3}}}}}} \end{gathered}[/tex]
Hence, the slope line is 4/3.

a figure is dilated by a factor of 3/4. by what factor will the area of the figure change
Answers
The area of the figure changes by a factor of 9/16, when the figure is dilated by a factor of 3/4
What is dilation?When a shape is dilated, the size of the shape changes (i.e. it either compresses or enlarges)
The scale factor (k) is given as:
[tex]k = \frac 34[/tex]
The area of the shape will change by the square of the scale factor.
So, we have:
[tex]Area = k^2[/tex]
This gives
[tex]Area = (\frac 34)^2[/tex]
[tex]Area = \frac 9{16}[/tex]
Hence, the area of the figure changes by a factor of 9/16

Anna paddled 16 km up river to see her uncle, and then returned downstream to her home. The river flows at a rate of 6 km/h, and Anna paddles at a rate of 10 km/h. What was her average speed in km/h?
Answers
Anna average speed in km/h is 7.5 km per hour
Average speed
Average speed is the ratio of total distance covered to total time taken. It is given by:
Average speed = Total distance / total time
Given the distance upstream is 16 km at a rate of 6 km/h, hence:
6 = 16/tt = 2.67 hoursThe distance downstream is 16 km at a rate of 10 km/h, hence:
10 = 16/tt = 1.6 hoursTotal distance = 16 km + 16 km = 32 km
Total time = 2.67 + 1.6 = 4.27 hours
Average speed = 32 / 4.27 = 7.5 km per hour

What is the value of x in the equation 3x + 2 + 3(1+x) = 23?
if u get it right in under 15 minutes i'll mark u brainllist
Answers
Answer:
3
Step-by-step explanation:
Let's start by simplifying the parenthesis. Distribute the 3 to the terms in it.
3x + 2 + 3 + 3x = 23
Simplify the like terms.
6x + 5 = 23
Isolate the x term by subtracting 5 on both sides.
6x = 18
Divide both sides by 6 to get the value of x.
x = 3
the equation is now 3x+2+3x+3=23
next add like terms to get 6x+4=23
next subtract the 5 on both sides to get 6x= 18
then divide by 6 on both sides to get 3.
so the answer is 3

Solve the following application problem. Be sure to show your system of equations and the steps to solve the problem.
Application Problem: It takes a boat 2 hours to go 16 miles downstream with the current and 4 hours to return against the current. Find the speed of the boat in still water and the speed of the current.
Answers
Answer:
boat: 6 mphcurrent: 2 mphStep-by-step explanation:
The relationship between time, speed, and distance is ...
speed = distance/time
For boat speed b and current speed c, the speed downstream is ...
b +c = (16 mi)/(2 h) = 8 mi/h
The speed upstream is ...
b -c = (16 mi)/(4 h) = 4 mi/h
Adding the two equations eliminates the c term:
2b = 12 mi/h
b = 6 mi/h . . . . . divide by 2
Solving the second equation for c, we get ...
c = b -4 mi/h = 6 mi/h -4 mi/h = 2 mi/h
The speed of the boat in still water is 6 mi/h; the current is 2 mi/h.

Debbie's bank offers an online bill pay service. For this, the bank charges $2.25 per month plus $0.10 per bill paid using the service. How many bills does she pay each month if the charges are always between $3.50 and $5.00? (Note: She is not allowed to pay part of a bill.)
Answers
Based on the information given, the number of bills will have to be between 13 and 28 every month.
Solving equationsLet the number of bills be represented by x.
Therefore, the equation to solve the question will be:
2.25 + (0.10 × x) = 3.50
2.25 + 0.10x = 3.50
0.10x = 3.50 - 2.25
0.10x = 1.25
x = 1.25/0.10 = 12.5 = 13
Also, 2.25 + 0.10x = 5.00
0.10x = 5.00 - 2.25
0.10x = 2.75
x = 27.5 = 28
Therefore, the number of bills will be between 13 and 28 every month.

The first angle measures 60 degrees. The second angle measures 60 degrees. The third angle is labeled y. The line between the 70 degree angle and angle y extends below the straight line. The angle formed is labeled angle x. Write and solve an equation to determine the measure of angle x.

The value of x is 50°.Step-by-step explanation:
We know that:
x = y2(70 + 60) + x + y = 360Work:
2(130) + x + x = 360=> 260 + 2x = 360=> 2x = 360 - 260=> 2x = 100=> x = 50Hence, the value of x is 50°.
Hoped this helped.
[tex]BrainiacUser1357[/tex]
Answer:
x =50° , y = 50°
we know that angles on a straight line equals to 180°
here,
y + 70° + 60° = 180° ( as lies on straight line )
y = 180° - 70° - 60° ( changing sides, changes the sign + to - and - to positive )
y = 50°
we can see y = x as they are parallel to each other
so x = 50°
