From the graph, write the linear equation in slope-intercept form
Answer:
y = -3x + 1
Step-by-step explanation:
slope intercept form -> y=mx+b
you can find your slope, m, by doing rise over run ( up 3, left one -> -3/1 )
you can find your y-intercept, b, by just looking at the y axis ( 0,1 -> 1 )
from there you just plug in the values
y = m ( slope ) x + b ( y-intercept )
y = -3x + 1
One fifth of the difference of a number and 1?
If you are asking for that to be in expression form, that would be:
1/5(x-1)
Let x be the number.
Answer: The expression that models this situation is given by:
x-1/5
---------------------------
The number is unknown, so it is called x.
The difference between 3 and 2 is 3 - 2 = 1, between 10 and 5 is 10 - 5 = 5, and so on. Thus, the difference between a number and 1 is x - 1.
One fifth of a number is the number divided by 5. Thus, in this context, the expression that represents one fifth of the difference of a number and 1 is given by:
x-1/5

plz help me what the coordinate points for each
Answer:
A. (-4, -3)
B. (5, 3)
C. (-1, 3)
Step-by-step explanation:
Ok, bear with me, its been a while since I have done this so make sure you double check.
A. So, we already know where point A is(1,-3) and we need that to find B
It says we need a reflection which is basically mirroring it across the y-axis(note: if it were across the x-axis then this would turn out much differently.)
Its hard to explain but i will tell you that reflecting point A will give us (-1, -3)
Now we need to translate it 3 units to the left
(-4, -3)
B. Ok, next we have point C which is a reflection using the x-axis (now you will see how important it is to make sure you are reflecting in the right place.) Over the x-axis, will give us (1, 3).
Now we need to translate to the right... (5, 3)
C. Point D... we need to rotate it. Now, rotating is a little bit more work than reflecting and translating but its not hard.
since we are rotating 180 degrees then we are basically just turning it around halfway from 360...
A is (1, -3) so D would be (-1, 3)

The U.S. population in 1910 was 92 million people. In 1990, the population was 280 million. This could either be a linear or exponential model. You will create both and then look at the true population increase and decide which model is closer the the true growth.
The actual U.S. population data (in millions) was:
Which model provides a better forecast for the U.S. population for the year 2030, linear or exponential or neither?
Question 5 options:
Linear model
Exponential model
Neither
Answer:
The linear model means that there is a uniform increase and in this case of US population from 92 million people in 1910 to 250 million people in 1990 .
This means an increase of 250 − 92 = 158 million in 1990 -1910 = 80 years or 158 80 = 1.975 million per year and in x years it will become 92 + 1.975 x million people. This can be graphed using the linear function 1.975 ( x − 1910 ) + 92 ,
graph{1.975(x-1910)+92 [1890, 2000, 85, 260]}
The exponential model means that there is a uniform proportional increase i.e. say p % every year and in this case of US population from 92 million people in 1910 to 250 million people in 1990 .
This means an increase of 250 − 92 = 158 million in 1990 − 1910 = 80 years or
p % given by 92 ( 1 + p ) 80 = 250 which gives us ( 1 +p ) 80 = 250 92 which simplifies to p = ( 250 92 ) 0.0125 − 1 = 0.0125743 or 1.25743 % .
This can be graphed as an exponential function 92 × 1.0125743 ( x − 1910 ) , which gives population in a year y and this appears as graph{92(1.0125743^(x-1910)) [1900, 2000, 85, 260]}

Which of the following statements is true in its conditional and converse forms?
If K is between points J and L, then K is a midpoint.
If a polygon has 3 sides, then the sum of its interior angles is 180°.
If two angles are right angles, then they are congruent.
If B is the midpoint of AC¯¯¯¯¯¯¯¯, then AB = BC.
The converse statement involves switching the hypothesis and the conclusion of a conditional statement.
The correct statement is (d) If B is the midpoint of AC, then AB = BC.
The converse of the given conditional statements are:
If K is a midpoint, then K is between points J and LIf the sum of interior angles is 180°, then the polygon has 3 sidesIf two angles are congruent, then they are right anglesIf AB = BC, then B is the midpoint of ACFrom the above statements, (a), (b) and (c) are not the same as the conditional statement, because:
Point K does not have to be between points J and L to be a midpoint.The sum of interior angles of all polygons (whether it has 3 sides or more) is 180 degreesCongruent angles may not be right anglesFor option (d):
For B to be a midpoint of AC, it means that sides AB and BC are congruent.
Hence, the correct statement is (d)

can someone please help me with how to find the perimeter and area of this
Answer:
Perimeter = 68ft
Area = 289ft²
Step-by-step explanation:
The lines on each side mean that they are all the same length - this shape is a square.
To find the perimeter, do 17 + 17 + 17 + 17 or 17 × 4. This gives you 68ft.
To find the area, you multiply the length and width → 17 × 17 = 289ft²

Solve the simultaneous equation
2x-5y=9
3x+4y=2
Answer/Step-by-step explanation:
2x-5y=9
Add 5y to both sides of the equation.
2x=9+5y
Divide each term by 2 and simplify.
Divide each term in 2x=9+5y by 2
[tex]\frac{2x}{2} =\frac{9}{2} +\frac{5y}{2}[/tex]
Cancel the common factor of 2.
Divide x by 1.
[tex]x=\frac{9}{2} +\frac{5y}{2}[/tex]
[tex]y=\frac{-9}{5} +\frac{2x}{5}[/tex]
----------------------------------------------------------------------------------------------------------------
3x+4y=2
Add 4y to both sides of the equation
3x=2+4y
Divide each term by 3 and simplify.
Divide each term in 3x=2+4y by 3.
[tex]\frac{3x}{3} =\frac{2}{3} +\frac{4y}{3}[/tex]
Cancel the common factor of 3.
Divide x by 1.
[tex]x=\frac{2}{3} +\frac{4y}{3}[/tex]
[tex]y=\frac{-1}{2} +\frac{3x}{4}[/tex]

Answer:
C. temperature outside
Step-by-step explanation:
Discrete data is information that can only take certain values. ... This type of data is often represented using tally charts, bar charts or pie charts. Continuous data is data that can take any value. Height, weight, *TEMPERATURE* and length are all examples of CONTINUOUS data. = not discrete data

A line with a slope of 5 passes through the points (4,5) and (5,u) What is the value of u?
Answer:
See Below
Step-by-step explanation:
Slope is rise over run.
Rise is the difference in the y values
Run is the difference in the x values.
Rise/Run = 5 (slope)
You have both x values 4 from one point and 5 from the other point so the difference is 1. The Run is equal to 1
So you now have Rise / 1 = 5
The first y value you have is 5 and based on (rise/1 = 5), you know the difference in the y values must equal 5. That means the other y value has to be either 10 or 0.
0 will not work because that would make the slope negative since the line would slope downward from left to right.
