Answer:
t = 2
Explanation:
To solve this equation, add nine to both sides. This will isolate the variable (t) and allow us to find its value.
[tex]-9 + t = -7\\(-9 + 9) + t = (-7 + 9)\\t = (-7 + 9)\\t = 2[/tex]
If you would like to double check that the variable (t) does in fact equal two, substitute the value of the variable in the equation and solve.
[tex]-9 + t = -7\\-9 + 2 = -7\\-7 = -7 [true][/tex]
Therefore, the value of t in the given equation is 2.

A student is using a table of values to graph the line y = -2x + 3. The student's table is shown below. What number would this student fill in for the "?" in the table? x y -4 11 -5 13 -6 ?
Answer: Y
Intercept Is the correct answer
Step-by-step explanation:
Let f(x) = x2 and g(x) = x - 6. What is fog?
I am not sure if your question is saying f(x) is x² or if it is 2x so I am giving you two answers.
If f(x) is x² the answer for f(g(x))= (x-6)²
If f(x) is 2x the answer for f(g(x))=2x-12
How did I get these answers? For fog, it basically means f(g(x)) so you just plug in what g(x) equals for the variable x in f(x)
What is the midpoint of (-9,5) and (21,-7)
Answer:6,-1
Step-by-step explanation:
Answer:
(-9,5) (21,-7)
[tex](\frac{-9+21}{2};\frac{5-7}{2})=(\frac{12}{2} ;\frac{-2}{2})=(6,-1)[/tex] this is the midpoint

I need help solving it
Answer:
the answer is 2
Step-by-step explanation:
add -4x and -6x and the answer is -10x bc they are both negative x. then divide both -10x and -20 by -10 so that it is x by itself on one side and 2 on the other so its 2=x :)

which expression is equivlent to 4(x+2y)
Answer:
[tex]\huge\boxed{4x+8y}[/tex]
Step-by-step explanation:
In order to find an expression equivalent to [tex]4(x+2y)[/tex], we want to simplify the equation down.
To do this, we can see that we can apply the distributive property on this equation. Basically, we multiply every term in the parentheses by 4.
[tex]4 \cdot x = 4x\\\\4 \cdot 2y = 8y\\\\4x+8y[/tex]
Hope this helped!

Which statement is true about a translation? 1. A translation takes a line to a parallel line or itself. 2. A translation takes a line to a perpendicular line. 3. A translation requires a center of translation. 4.A translation requires a line of translation.
Answer: 1. A translation takes a line to a parallel line or itself.
Step-by-step explanation:
I took the quiz myself.
When a line is translated, it means the line is moved from one position to another. The true statement is:
(1). A translation takes a line to a parallel line or itself.
In transformation, translation does not change the orientation of a line. This means that:
The position of the lines will change, when translatedThe orientation of the lines will remain unchangedIt does not require a center or scale of translationPoint (2) above means that;
Parallel lines will remain parallelPerpendicular lines will remain perpendicularUsing the above analysis, we can conclude that: option (1) is true

If AB = 8 and BC = 24, then AC =
If AB = 17 and AC = 68, then BC =
Answer:
(i) The length of AC is 32 units, (ii) The length of BC is 51 units.
Step-by-step explanation:
(i) Let suppose that AB and BC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:
[tex]AC = AB + BC[/tex]
If we know that [tex]AB = 8[/tex] and [tex]BC = 24[/tex], then:
[tex]AC = 8 + 24[/tex]
[tex]AC = 32[/tex]
The length of AC is 32 units.
(ii) Let suppose that AB and AC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:
[tex]AC = AB + BC[/tex]
[tex]BC = AC - AB[/tex]
If we know that [tex]AC = 68[/tex] and [tex]AB = 17[/tex], then:
[tex]BC = 68-17[/tex]
[tex]BC = 51[/tex]
The length of BC is 51 units.

The area of a rectangle is x 2 – 3x – 28. If the
length is x + 4, find the width.
Answer:
-4 square units
Step-by-step explanation:
a = l × b
x2 - 3x - 28 = (x +4)(×)
x2 - 3x - 28 = x2 + 4x
-3x - 28 - 4x = 0
-7x - 28 = 0
-7x = 28
x = -4

Answer:
Susan is correct. If you divide the unit price (the price of each individual soda) by the number of people, you will get the total cost of the soda. Or in other words, how much money you're putting down to buy this soda for X amount of people. John is incorrect because by dividing the cost of a 12 pack soda by the number of sodas, he is determining the cost of each individual soda, not the total cost.
