Answer:
Step-by-step explanation:
a and d are in standard form.
b and c are in factored form
ax² + bx + c ---> this is the standard form.
If the equation is written as product of two terms then it is in factored form.
Angles A and B are supplementary. If mA = 67, find mB.
Answer:
Angle A +Angle B=180
67+B=180
B=113°
the first row the theater has 15 seats in it each subsequent row has 3 more seats that seats that the previous ow . if the last row has 78 sears, how many rows are in the theater a 21 b 78 c 77 d 45 e 22
Answer:
21
Sorry if not correct
But I think this is the answer
The number of rows in the considered theater which has 3 more seats that seats that the previous row, with first row having 15 and last row having 78 seats is given by: Option D: 22
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:
[tex]a, a + d, a + 2d, ... , a + (n+1)d, ...[/tex]
Its nth term is
[tex]T_n = a + (n-1)d[/tex]
(for all positive integer values of n)
And thus, the common difference is
[tex]T_{n+1} - T_n[/tex]
for all positive integer values of n
For this case, we can use arithmetic sequence as the number of seats in each next row is 3 more than previous row, so there is constant difference.
Now, the first number is 15, so we have: a = 15,d = 3 (increasing, so positive).
Let there are 'n' row in the theater.
Then the nth term of the arithmetic sequence having a = 15 and d = 3 should be 78 (as the nth row from first to last is the last row, having 78 seats).
Thus, we get:
[tex]T_n = a + (n-1)d\\78 = 15 + (n-1)3\\78-15 =3n - 3\\\\n = \dfrac{63+3}{3} = 22[/tex]
Thus, the number of rows in the considered theater which has 3 more seats that seats that the previous row, with first row having 15 and last row having 78 seats is given by: Option D: 22

Jimmy and Ted each improved their yards by planting daylilies and shrubs. They brought theurbsupplies from the same store. Jimmy spent $80 on 4 daylilies and 9 shrubs. Ted spent $148 on daylillies and 4 of shrubs. What is the cost of one daylily and the cost of one shrub?
Step-by-step explanation:
given,
JIMMY bought,
no. of daylillies = 4
no. of shrubs = 9
total cost of all material he bought = $80
TED bought,
no. of daylillies = 12
no. of shrubs = 4
total cost of all material he bought = $148
let daylillies be x and shrubs be y
the equation is,
4x + 9y = $80 -----------(1)
12x + 4y = $148 -----------(2)
now, multiply (1) by 3 we got,
12x + 27y = $240 -----------(3)
now, subtract (2) from (3) we got,
23y = 92
→ y = 92/23 = 4
→ y = 4
therefore cost of shrubs are $4.
so, cost of daylillies,
→ 12x + 4(4) = 148
→ 12x = 148 - 16 = 132
→ x = 132/12 = 11
→ x = 11
Hence, cost of daylillies are $11 and shrubs are $4.

Answer:
x = - 1
Step-by-step explanation:
3(x + 2) = 2x + 5 ← distribute parenthesis on left side by 3
3x + 6 = 2x + 5 ( subtract 2x from both sides )
x + 6 = 5 ( subtract 6 from both sides )

Gabrielle’s age is two times Michaels age. The sum of their ages is 39. What is Mikhails age?
Based on the given information, Michael's age is 13, and Gabrielle's age is 26.
Let's represent Gabrielle's age as G and Michael's age as M.
Given that Gabrielle's age is two times Michael's age, we can express this relationship as:
G = 2M.
We also know that the sum of their ages is 39:
G + M = 39.
Now, we can substitute the value of G from the first equation into the second equation:
2M + M = 39.
Combining like terms:
3M = 39.
To isolate M, we divide both sides of the equation by 3:
M = 39 / 3.
Simplifying further:
M = 13.
Therefore, Michael's age is 13.
To confirm this result, we can substitute M = 13 back into the equation G = 2M:
G = 2(13).
G = 26.
So, Gabrielle's age is 26.

Write the equation of the line in fully simplified slope intercept form
Answer:
y = 3x - 8
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
4 - 1 / 4 - 3 = 3/1 = 3
m = 3
b = y-intercept
b = -8
y = mx + b
y = 3x + (-8)
y = 3x - 8

Use the figure at the right. If BE = 3x + 6 and DF = 7x +4, find DF.
Line segments can be divided into sub-segments.
The value of DF is 18
The given parameters are:
[tex]\mathbf{BE = 3x + 6}[/tex]
[tex]\mathbf{DF = 7x + 4}[/tex]
We have:
[tex]\mathbf{BE + DF = 30}[/tex]
So, we have:
[tex]\mathbf{3x + 6 + 7x + 4 = 30}[/tex]
[tex]\mathbf{10x + 10 = 30}[/tex]
Subtract 10 from both sides
[tex]\mathbf{10x = 20}[/tex]
Divide both sides by 10
[tex]\mathbf{x = 2}[/tex]
Substitute [tex]\mathbf{x = 2}[/tex] in [tex]\mathbf{DF = 7x + 4}[/tex]
[tex]\mathbf{DF = 7 \time 2 + 4}[/tex]
[tex]\mathbf{DF = 14 + 4}[/tex]
[tex]\mathbf{DF = 18}[/tex]
Hence, the value of DF is 18
