Write a equation in slope intercept form that is equivalent to 10x-2y=16
Answer:
y = 5x - 8
Step-by-step explanation:
10x -16 = 2y
y = 10/2x - 16/2
y = 5x - 8
In ∆PQR, m P = 60°, m Q = 30°, and m R = 90°. Which of the following statements about ∆PQR are true? Check all that apply.
A. PQ = √3 • PR
B. PQ = 2 • PR
C. QR = 2 • PR
D. QR = √3/2 • PQ
E. QR = √3 • PR
F. PR = √3/2 • PQ
Answer:
C. QR = 2 • PR
Step-by-step explanation:
According to given information we can draw a right triangle with angle measures as follows :
30-60-90 and for this special right triangle the side length would follow as:
The side length that sees angle measure 30 = a
The side length that sees angle measure 60 = a[tex]\sqrt{3}[/tex]
The side length that sees angle measure 90 = 2a
following this information the:
PR(sees 30 degrees) = a (can be represented as PR in this case)
and so
QR(sees 90 degrees) = 2a (2*PR in this case)
PQ(sees 60 degrees) = a[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] *PQ in this case)
The correct option is C. QR = 2 • PR

Step-by-step explanation:
A hamburger costs twice as much as a hot dog. Three hamburgers and two hot
dogs cost $21. Choose the system of linear equations that represents this problem.
A. 2y=x
2x+3y=21
B. y=2x
2x+3y=21
C.x=2y
3x+2y=21
D.y=2x
3x+2y=21
Answer:
C
Step-by-step explanation:
Hamburger = Hotdog x 2
3(Hamburger) + 2(Hotdog) = 21
Now replace with x (Hotdog) and y (Hamburger)
y = 2x
3y + 2x = 21

is this graph skewed or roughly symmetrical?
Answer: Roughly Symmetrical
Step-by-step explanation: There's no super easy way to explain why other than learning with experience but if you look at about the center of the graph, there are two peaks, and each side of the graph if split at about 68 which is the center, has 7 points each. This in conjunction with the shape and relatively normal spread makes it roughly symmetrical, not quire symmetrical but getting there.
Tia went to the Farmers
Market and bought 6
pineapples for $3.49
each. How much money did
Tia spend?

there are 3 factors in the equation 5 x 3 x 2 = 30 true or false
Answer:
true
Step-by-step explanation:
the factors are simply what is being multiplied together. We can see there are 3 because we have 5,3,and 2. 30 is not a factor because that is the answer. I hope this helps!
solve pls brainliest
Answer:
a) 5
b) 9
Step-by-step explanation:
The lines by the side decide absolute value, meaning distance from zero. for question A, simply add the integers to get -5. With the absolute value lines surrounding the question, you must make the answer 5 instead of -5 to show the distance from zero. In easier words, absolute value is just the positive number of an integer. For question B, the absolute value is surrounding just the -7, making it a positive 7. So, you simply just add 7 + 2 for question B, getting 9.

Y'' − 2y' + y = 0 ; y(0) = 5 , y'(0) = 10
Answer:
correct
Step-by-step explanation:
fill the table using this function rule
y=-10x+3
Answer:
53, 13, 3, -7
Step-by-step explanation:
When x = -5,
y = -10(-5) + 3
= 50 +3
= 53
When x = -1,
y = -10(-1) + 3
= -10 + 3
= 13
When x = 0,
y = 3
When x = 1,
y = -10(1) + 3
= -7

if you write 14 to the power of 6
in expanded form, how many factors will there be?
9514 1404 393
Answer:
6
Step-by-step explanation:
The power is used to signify repeated multiplication in the same way a multiplier signifies repeated addition.
14⁶ = 14×14×14×14×14×14
There are 6 factors of 14.

Looking for the answer for the second one
Answer:
3 for the left one, and 5 on the right one.
Step-by-step explanation:
The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)
If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.
If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.
4. The six employees in the security department of a company average $120 gross pay a day. Three of the
employees earn $125 per day. Two others eam $116.50 a day. How much does the sixth employee eam per

Your grandfather placed $5,000 in a trust fund for you. In 12 years, the fund will be
worth $10,000. What is the rate of return on the trust fund?
Answer:
fv/pv=(1+r)^n
10,000/5000=(1+r%)^12
2=(1+r%)^12
r= 5.95
Step-by-step explanation:
fv/pv=(1 + r)^n
10000/5000=(1 + r%)^12
2=(1 + r%)^12
r=5.95
