Answer:
10 in
Step-by-step explanation:
This question can be solved with a proportion. 12 is to 8 as 15 is to x since the triangles are congruent. So solve 12/8=15/x. Then cross multiply to get x=10.
(x² – 5x – 1)(x²+ 2x + 3)
answer
[tex] {x}^{4} - 3 {x}^{3} + 8 {x}^{2} - 17x - 3[/tex]
(1/2)^x=16^2
Could you please help me with the step-by step? This problem is giving me trouble.
Write both sides as powers of 2. First,
1/2 = 2⁻¹
16 = 2⁴
so the equation can be rewritten as
(1/2)ˣ = 16²
(2⁻¹)ˣ = (2⁴)²
Recall that [tex](a^b)^c=a^{bc}[/tex], so that
2⁻ˣ = 2⁸
The bases are the same, so the exponents must be equal:
-x = 8
x = -8

How do I factor the polynomial -7y+y^2-30? I can do it in standard form but now im confused. Please help.
Answer:
your answer would be
(y - 10) (y + 3)
hope this helps
Answer:
Step-by-step explanation:
-7y+y^2-30 is presented legally, but not logically I will re-write it better
just re-write in standard form
y^2 - 7y - 30
y² - 7y - 30 is it better now?
(y - 10) (y + 3)

Answer:
a₂₀ = 69
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 15 - 12 = 3 , then
a₂₀ = 12 + (3 × 19) = 12 + 57 = 69

James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.
Answer: $339
Step-by-step explanation:
Given
The total length of the journey is 10 miles
fixed pledges are $300
variable pledges are $13 per mile
Point slope equation form is
[tex]\Rightarrow y=mx+c[/tex]
Here the total charge corresponds to y and miles walked corresponds to x
So, we can write
[tex]T=13\times m+300[/tex]
where,
[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]
for 3 miles distance
[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)
Answer:
C E

Answer:
-6
Step-by-step explanation:
it's asking when x is equal to -5 what is y equal to?
there's only one point when x=-5 and it's -6
so the point is (-5,-6) and y is equal to -6

Step-by-step explanation:
8+5=12
12/2=6
It takes40/ 13 or approximately 3.1 hours to do the job with both printers working on it.
What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

Step-by-step explanation:
The field has the shape of a trapezoid. Its area can be found using the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
A = (1/2)(399 +594)(506) = 251,229 . . . . . . acres
__
At 38909 plants per acre, the number of plants that should be planted for maximum yield is ...
(251,229 ac)(38,909 plants/ac) = 9,775,069,161 plants
_____
Comment on units
The problem statement tells us "each unit of coordinate plane represents one acre." An acre is a unit of area, so we have to assume this means that each square unit represents one acre. That means each unit on each axis is about 208.71 feet, the dimension that would have to be squared to get an area of one acre--43,560 square feet.

Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
