Answer:
x = √48
Step-by-step explanation:
[tex] ({3}^{ \frac{x}{2} } )( {3}^{ \frac{x}{4} }) = 3 {}^{6}[/tex]
[tex] {3}^{ \frac{x}{2} \times} {}^{ \frac{x}{4} } = 3 {}^{6} [/tex]
[tex]3 {}^{ \frac{ {x}^{2} }{8} } = 3 {}^{6} [/tex]
[tex] \frac{ {x}^{2} }{8} = 6[/tex]
[tex] {x}^{2} = 6 \times 8[/tex]
[tex] {x}^{2} = 48[/tex]
[tex]x = \sqrt{48} [/tex]

Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40
solve the inequality
7y+2<5y+12
Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]
= y < 5

The transformation formula of a horizontal-facing parabola is:
x = ±a(b(y - k)) + h, where the vertex is at (h, k).
Looking at the graph, we can see a vertex at (-2, -3) with a stretch of 2. The graph is also pointed towards the RIGHT, which means that the coefficient "a" must be positive. Therefore:
The only logical answer choice is B, or x = 2(y + 3)² - 2.
The formula indicates that:
* Vertex at (-2, -3)
* Stretch of 2
* Right-facing parabola

Answer:
9.68
Step-by-step explanation:
it makes sense when u tink about ot
Answer:
Jamil buys 6 pens.
Step-by-step explanation:
Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90. If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

Step-by-step explanation:
because 26 is a negative you know that n has to be a positive so you subtract 13 from 26 and that's your answer
The equation for this graph is y = x +
Answer:
y=3x+2
Step-by-step explanation:
The y intercept is 2. Therefore, we can plug 2 into b in y=mx+b because b is a y intercept.
The slope is 3 because if you go up 3 and right to the one (rise over run) the line will go through it. You can also make is -3 over -1 but that would just equal 3.

Step-by-step explanation:
Lane is making accessories for the soccer team. He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches. He also uses 361.21 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player? Please answer quick pls
Answer:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
Step-by-step explanation:
Lane is making accessories for the soccer team.
For headbands
He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches.
Hence:
Let the number of inches used for headbands be represented by x
41x + 2x = 721.54
43x = 721.54
x = 721.54/43
x = 16.78 inches
Hence the number of inches used to make head band for 1 player is 16.78 inches
He also uses 361.21 inches of fabric on wristbands for just the players.
We have 41 players hence:
41 players = 361.21 inches
1 player = x
41 × x = 1 × 361.21 inches
x = 361.21 inches/41
x = 8.81 inches
8.81 inches of fabric was used for wristbands for each player.
Hence:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player

What is the slope of the line that passes through the points (3,-2) and (1,5)?
Answer:
-7,2 I believe :)
Step-by-step explanation:
Rise over run
Put into an equation, y1-y2/1-x2
so its
-2-5/3-1 which gives you the answer of -7/2 :)
Answer:
m= 7/-2
Step-by-step explanation:
Use the slope formula.
y2 - y1 = 5 -- 2 = 7
x2 - x1 = 1 - 3 = -2
m = 7/-2

what is the slope and y-intercept of this graph?
Answer:
Slope is 2
Y-intercept is 7
Step-by-step explanation:
To find the slope we take any two points from the table
and use it in the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]
we take the points (0,7) and (1,9)
now we put these points in the formula and it becomes
[tex]m=\frac{9-7}{1-0}[/tex]
[tex]m=2[/tex]
so our slope which is m is 2 and now for the y-intercept we use the standard equation
[tex]y=mx+c[/tex]
where c is the y-intercept
we use the value of m which is 2 and use any point from the table lets take (0,7)
[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]
our y-intercept which is c is 7
so finally our slope is 2 and y-intercept is 7
