In montrel was -8 in new york it was 11 deggrees warmer, what was the tempreture in ny?
Answer:
3 degrees
Step-by-step explanation:
-8, -7 -6,-5,-4,-3,-2,-1,0, 1,2 3
If you count 11 spaces to the right on a number line, starting at -8, you will land at 3 degrees.
=========================================================
Explanation:
Think of the +11 as +8+3
Draw a vertical number line. Start at -8 on that number line. Then move up 8 units to arrive at 0. Afterward move the remaining 3 units to get to 3 on the number line. We've moved up a total of 8+3 = 11 degrees.
In other words, starting at -8 and moving up 11 units will have us arrive at 3
This visually shows -8+11 = 3

What is the equation in point-slope form of the line passing through (-1,3) and (1, 7)?
O a
y - 7 = 4(x - 1)
Ob
y-7 = 2(x - 1)
ос
y- 3 = 2(x - 1)
Od
y- 3 = 4(x + 1)
Answer:
y - 3 = 2(x+1)Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)
Explain why the two figures below are similar. Use complete sentences and provide evidence to support your explanation. (10 points) Figure ABCDE is shown. A is at negative 3, 1. B is at negative 1, 3. C is at 3, 3. D is at 2, 0. E is at negative 1, negative 1
Figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.
How to Identify Similar Triangles?
Similar triangles are triangles that have the same shape, but their sizes may vary.
In figure ABCDE vertices A,B,C,D,E are given so we can find their sides by applying distance formula:
D=√((x2 - x1)² + (y2 - y1)²)
With the help of this formula we can find AB;
AB = √(-1 - (-3))² + (3 - 1)²)
AB = √((-1 + 3)² + (2)²)
AB = √((2)² + (2)²)
AB = √(4 + 4)
AB = √8
AB = (√2*2) * 2
AB = 2√2
Likewise, we can find the remaining sides as;
BC = 4, CD = √10, DE = √10 and EA = 2√2
FG = √2, GH = 2,HI = 1.58114, IJ = 1.58114 and JF = √2
When the two figures are similar then the ratios of their corresponding sides are equal.
Thus, we have that;
AB/FG = BC/GH = CD/HI = DE/IJ = EA/JF
Therefore, we conclude that figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.

What is the value for f(x) =0
The function can be graphed to demonstrate this further. On the graph where f(x)=0, the curve is just the x-axis, which always has the same y-value of 0.
How to find the domain of a function ?Domaine:The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Given the function f(x)=0,
since this is a constant function (that is, for any value of x, f(x)=0, the limit of the function as x→a, where a is any real number, is equal to 0.
More specifically, as a constant function,f(x) maintains the same value for any x. f(1)=f(2)=f(π)=f(e)=f(−(1258567)/(44))=0. Further, as a constant function, f(x) is by definition continuous throughout its domain. Note, however, that if one arrives at a constant function via division or multiplication of non-constant functions (for example, (8x)/(x), there will still exist a discontinuity where the original denominator was0).
Graphing the function will further prove this point. On the graph f(x)=0, the curve is simply the x-axis, which maintains a constant y-value of 0 no matter the x-value.

3 Lila planted a tree in her backyard. She made this graph to show the tree growth for over 5 years. Part A Complete the equation to correctly show how to find the slope for the function shown in the graph.
Answer: Part A : slope = 20/1 -8/1 12/4 =3 Part B: The y-intercept is 5
Step-by-step explanation: I just did this with my teacher..Hope this helps! ( The numbers in bold are the answers)
The slope of the graph is 3 and the y intercept is 5.
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
Let y represent the height of the tree after x years.
The line passes through the point (0, 5) and (3, 14). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-5=\frac{14-5}{3-0} (x-0)\\\\y=3x+5[/tex]
Therefore the slope of the graph is 3 and the y intercept is 5.

Step-by-step explanation:
Tommy has $350 of his graduation gift money saved at home in the amount is modeled by the function h(x)=350. He reads about a bank that has savings account that accrue interest according to the function s(x)=(1.04))^x-1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposit his $350 justify your reasoning
Answer:
Step-by-step explanation:
His functions are:
h(x)= $350
s(x)=(1.04))^x-1
To find total amount of money in Tommy's account using the functions above, we substitute the first function x= $350 in the second function
So, we can say that the new function represents the interest received by
Tommy with initial saving $350.
Function:A function is a group of statements that together perform a task.
Given that Tommy got $350 as the gift which he saves.
So, the amount saved is given by the function is [tex]h(x)=350....(1)[/tex]
Also, the interest by the saving bank account is given by,
[tex]s(x)=(1.04)^{x-1}....(2)[/tex]
Comparing equations (1) and (2) we get a new function as,
[tex]g(x)=350(1.04)^{x-1}[/tex]
The function gives the value [tex]h(x)=350[/tex] when [tex]x=0[/tex] and the amount is increasing by the interest.

Find the value of x that will make A parallel to B
2x + 50
5x - 80
x = ?
Answer:
30
Step-by-step explanation:
If Line A is parallel to Line B, then 2x+50+5x-80 = 180. This is because 2x+50 is an alternate interior angle with the supplement of 5x-80, therefore the supplement of 5x-80 is also 2x+50. Supplementary angles add up to 180°.
Solve the Equation2x + 50 + 5x - 80 = 180 --> Combine like terms
7x - 30 = 180 --> Add 30 to both sides
7x = 210 --> Divide both sides by 7
x = 30
Check the Solution
We can check our answer by plugging 30 in for x back into our original equation.
2(30) + 50 + 5(30) - 80 = 180
60 + 50 + 150 - 80 = 180
110 + 150 - 80 = 180
260 - 80 = 180
180 = 180
Therefore x = 30.
