Given :
h(x) = 5 - 9x - equation (1)
h(x) = -67 - equation (2)
since, both of them are equal, let's equate :
5 - 9x = -67 -9x = -67 - 5-9x = -72 x = (-72) ÷ (-9) x = 8⇒h(x) = 5 - 9x
⇒h(x) = -67
Now, We'll make two equations,⇒h(x) = 5 - 9x ........ (Ⅰ)
⇒h(x) = -67 ......... (ⅠⅠ)
As, both the equations which we formed are equal, So, we'll equate both of them,⇒5 - 9x = -67
⇒-9x = -67 - 5 (Combining like terms)
⇒-9x = -72 (Since, (-) is common in L.H.S & R.H.S we'll cancel it out & we will get the values positive)
⇒x = 72/9 (Transposing 9 to R.H.S)
⇒x = 8 (Required Answer)

27. A parallelogram has a perimeter of 96 inches, and 1 of
its sides measures 16 inches. If it can be determined,
what are the lengths, in inches, of the other 3 sides?
Α.) 16, 16, 48
Β. 16, 24, 24
C. 16, 32, 32
D. 16, 40, 40
E. Cannot be determined from the given information
Answer:
C. 16, 32, 32
Step-by-step explanation:
Since it is a parallelogram, two of the sides must be 16, giving a total of 32. 96 - 32 is 64, meaning the other 2 sides are 64 ÷ 2, which is 32. So the sides are 16, 16, 32, 32.

PQR is an equilateral triangle. PQ=4 cm. what are the length of PR and QR? give reasons for your answer
Answer: PR and QR are both 4cm
Step-by-step explanation: If PQR is an equilateral triangle all sides must have the same length because that's the definition of an equilateral triangle. Therefore, PR and QR must also be 4 sides.

hi <3
you can use the keep flip change rule here.
it states that when dividing fractions, to solve them you can keep the first fraction the same, flip the second one and change the sign into a multiply one
thus you get:
1/5 x 5/4
now you can just multiply across to get an answer of 5/20 or simplified this would be 1/4.
i'm not sure if you had options you had to select from but you can drop them below if you need that.
hope this helps :)

For which value of x is the figure a rhombus?
A. X=6
B. X= 7.5
C. X=12
D. X=18.75
That is a question about properties of rhombus.
There is a property of a rhombus that says that the its diagonals divided the internal angles in two equals angles.
Now that we know about it, it is easier to solve this question, because now we know that [tex]2x+39[/tex] and [tex]6x - 9[/tex] are equal angles. So, we can make a equation and solve it:
[tex]2x+39 = 6x - 9\\39 + 9 = 6x - 2x\\48 = 4x\\4x = 48\\x=\frac{48}{4} \\x=12[/tex]
Therefore, the value of [tex]x[/tex] is 12. So, the correct alternative is letter C).
I hope I've helped. ^^

Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?
We have an algebra problem.
We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.
The information given is:
The pickup can travel 45 miles on 3 gallons of gas.
To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)
This is:
r = (45 miles)/(3 gallons) = 15 miles/gallon.
Now that we know this, the number of gallons needed to travel 30 miles is given by:
N = (30 miles)/(15 miles/gallon) = 2 gallons.
N = 2 gallons.
The pickup needs 2 gallons to travel 30 miles.

does a ti 83 plus calculator work the same as a ti 84?
Answer:
Yes. Both are graphing calculators. TI 83 has a black only screen while the TI 84 has a colored screen
Yes. The two calculators are the same more or less overall. They have the same functions and features. There are slight differences (eg: the TI84 is slightly faster than the 83 version), but it's not too big a deal since you can do the same math with both versions.
If you can, I recommend using online tools such as Desmos or GeoGebra. These tools are much faster compared to the TI83 and TI84. Also, they allow for multiple colors to be used, so you can tell the graphs apart. There are lots of other features as well (way too many to go over right now), and the best part is that both tools Desmos and GeoGebra are free. Unfortunately, your teacher may not allow you to use them in a test setting. However, I would ask and they may allow a limited version to be used in some capacity.
