Answer:
a. y = 3
b. x = 1
c. y-intercept = 5
d. x-intercept = -2.5
e. 2
f. y = 2x + 5
Step-by-step explanation:
Based on the graph, we can see the point where x is -1, y = 3.
Based on the graph, we can see the point where y = 7, x = 1.
Based on the graph, we can see the y-intercept is 5.
Based on the graph, we can see the x-intercept is -2.5.
To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{5-3}{0-(-1)}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5
Find the measure of the missing angle
Answer: b=112 degrees and c=68
Step-by-step explanation:
Answer:
b = 112, c = 68
Step-by-step explanation:
The angle of a line is 180 degrees.
If an angle is 112, 180-112=68 so that blank space will be 68 degrees.
180-68=112, so b=112.
Since b is 112, we now that c is 68.

What is the length of NM?
Answer:
See below :)
Step-by-step explanation:
We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3
[tex]\frac{6}{\sqrt3}[/tex]
We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3
[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]
This then makes it 6 times root 3 over 3
[tex]\frac{6\sqrt3}{3}[/tex]
We then get [tex]2\sqrt{3}[/tex]
Expand and simplify 2(5x + 3) - 2(2x - 3)
Answer: It is 6x+12
Step-by-step explanation: Distribute 2 to the parenthesis, then do the same at the second parenthesis, 10x+6-4x+6, combine like terms, 10x-4x and +6+6, so 6x+12 is the final result.

Answer:
y = 2x², 0, 2, 8
y = 2^x, 1, 2, 4
Step-by-step explanation:
For the first equation, multiply the input by itself and then multiply by two
y = 2x²
y = 2(2)²
y = 2(2*2) = 8
For the second equation, multiply 2 by itself depending on the value of the input
y = 2^x
y = 2²
y = 2 * 2 = 4
Find 62÷2. Use the distributive property.
Answer: The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Step-by-step explanation: According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Answer: 31
First, we can break down the number 62.
We will break the number 62 down into 60 + 2.
Now, we will divide the numbers we get after we break down 60.
60 ÷ 2 = 30
2 ÷ 2 = 1
30 + 1 = 31
The answer to your question is 31.

SAVINGS Natalie has $250 in her savings accountinto which she deposits $10 of her allowance each week. The balance of her savings account can be modeled by the function f(w) = 250 + 10w , where w represents the number of weeks. Write a function g(w) to represent the balance of Natalie's savings account if she withdraws $40 to purchase a new pair of shoes. Describe the translation of f(w) that results in g(w) .
Answer:
[tex]g(w) = 210+ 10w[/tex]
Step-by-step explanation:
Given
[tex]f(w) = 250 + 10w[/tex]
[tex]Withdrawal = \$40[/tex]
Required
Determine g(w)
First, we'll write an expression for g(w)
From the question, we understand that she withdrew $40 from her account balance in w weeks.
This implies that:
[tex]g(w) = f(w) - 40[/tex]
Where f(w) is the account balance in w weeks and $40 is the withdrawn amount
Substitute 250 + 10w for f(w)
[tex]g(w) = 250 + 10w - 40[/tex]
Collect Like Terms
[tex]g(w) = 250 - 40+ 10w[/tex]
[tex]g(w) = 210+ 10w[/tex]
Recall that:
[tex]g(w) = f(w) - 40[/tex]
This means that function f(w) when shifter by 40 units downward, gives g(w)
Adsila and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes, Adsila fills 11 boxes every hour. How many boxes does Carlos fill every hour?
Answer:
Carlos fills 16 boxes per hour.
Step-by-step explanation:
Given that:
Adsila and Carlos are working together to fill the gift boxes for soldiers.
Number of boxes filled while working together in 4 hours = 108 boxes
Number of boxes filled while working together in 1 hour = [tex]\frac{108}{4} = 27[/tex] boxes per hour
Number of boxes filled by Adsila every hour = 11 boxes
To find:
Number of boxes filled by Carlos every hour = ?
Solution:
Number of boxes filled every hour while working together = Number of boxes filled every hour by Adsila + Number of boxes filled every hour by Carlos
Number of boxes filled every hour while working together = 27 = 11 + Number of boxes filled every hour by Carlos
Number of boxes filled every hour by Carlos = 27 - 11 = 16

Which point lies on the circle x^2+y^2=100
A (0,-100)
B (10,-10)
C (25,75)
Answer:
NOT a single ordered pair satisfies the equation.
Step-by-step explanation:
Given the equation
[tex]x^2+y^2=100[/tex]
Let us substitute all the given ordered pairs to find which ordered pair satisfies the equation.
For (0, -100)
[tex]x^2+y^2=100[/tex]
substitute x=0 and y=-100
[tex]0^2+\left(-100\right)^2=100[/tex]
[tex]10000=100[/tex]
FALSE
Thus, the ordered pair (0, -100) does NOT satisfy the equation.
For (10, -10)
[tex]x^2+y^2=100[/tex]
substitute x=10 and y=-10
[tex]10^2+\left(-10\right)^2=100[/tex]
[tex]200=100[/tex]
FALSE
Thus, the ordered pair (10, -10) does NOT satisfy the equation.
For (25, 75)
[tex]x^2+y^2=100[/tex]
substitute x=25 and y=75
[tex]25^2+\left(75\right)^2=100[/tex]
[tex]6250=100[/tex]
FALSE
Thus, the ordered pair (25, 75) does NOT satisfy the equation.
Therefore, NOT a single ordered pair satisfies the equation.
