A. 5 (b+2)
B. 5b+2
C. (b+2) over 5
D. b over (5+2)
Answer:
A
Step-by-step explanation:

Find twe positive even consecutive intecers such
that the square of the smaller integer is 10 more
than the larger integer.
Answer:
The numbers are 4 and 6
Step-by-step explanation:
Let:
x - the smaller even consecutive integer x+2 - the larger even consecutive integerwe know that
[tex]x^{2} =(x+2)+10[/tex]
solve for x
[tex]x^{2} -x-12=0[/tex]
We can use the quadratic formula for quadratics in the form [tex]ax^{2} +bx+c=0[/tex]
[tex]x= \frac{-b(+/-)\sqrt{b^{2} -4ac}}{2a}[/tex]
to give us an answer of 4 and -3
Since the question states positive and even we use 4 and that gives us 6 as the other answer
4 and 6
Answer:
4 and 6
Step-by-step explanation:
x = smaller integer
x+2 = larger integer
x² = 10 + (x + 2)
x² = x + 12
x² - x - 12 = 0
factors are:
(x-4)(x+3) = 0
x-4=0; x = 4
x+3=0; x = -3
Since the question states the numbers are even and positive we use only the 4 and the next consecutive even integer is 6

Question 2
x = ?
Answer:
x=20
Step-by-step explanation:
These these angles are adjacent
because they share a vertex and side. They also form a linear pair meaning they add up to 180 degrees...
x+20+7x=180
Combine like terms
8x+20=180
Subtract 20 from both sides
8x=160
Divide both sides by 8
x=20

Three trigonometric functions for a given angle are shown below. Sine theta = Negative StartFraction 77 Over 85 EndFraction, cosine theta = StartFraction 36 Over 85 EndFraction, tangent theta = Negative StartFraction 77 Over 36 EndFraction What are the coordinates of point (x, y) on the terminal ray of angle mc020-2. Jpg, assuming that the values above were not simplified? (–77, –36) (–77, 36) (–36, 77) (36, –77).
Trigonometric functions are the ratio of the different sides of a right-angled triangle. We can say that the coordinates of the point are (-77, 36).
What are trigonometric functions?
Trigonometric functions are the ratio of the different sides of a right-angled triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Given to us
[tex]Sin(\theta) = \dfrac{-77}{85}[/tex]
[tex]Cos(\theta) = \dfrac{36}{85}[/tex]
[tex]Tan(\theta) = \dfrac{-77}{36}[/tex]
As we know that the Tangent(Tan) is the ratio of perpendicular and base. therefore, we can write the function as,
[tex]\rm Tan(\theta) = \dfrac{Perpendicular}{Base} = \dfrac{-77}{36}[/tex]
therefore, the length of the perpendicular is 77, while the length of the base is 36.
As given to us that the value of sin is negative, therefore, the perpendicular will be on the negative side of the y-axis. While the value of cos is positive, therefore, the base will be on the positive side of the x-axis.
Thus, we can say that the coordinates of the point are (-77, 36).

two consecutive odd numbers between 60 and 80 which are both prime?
Answer:
Hello I'll help you :))!
So there are 21 numbers from 60 to 80 both terms inclusive.
We ignore all even numbers in this range as even numbers can not be prime.
The odd numbers are 61,63,65,67,69,71.73,75,77,79.
So remaining numbers are prime. They are 61,67,71,73,79.
So there are 5 prime numbers in this range.

You may notice that the two segments of the hypotenuse, x and 25, have a product that is the square of the altitude. Another way to say this is that the altitude is the geometric mean of the segments x and 25.
There are two other geometric mean relations in this geometry:
the short side at the right is the geometric mean of x and (x+25).
the long side at the bottom is the geometric mean of 25 and (25+x).
That is, the segments that intersect the hypotenuse are the geometric mean of the two segments of the hypotenuse that they meet.
geometric mean of A and B is √(AB)

Find the nth term rule for 18,15,12,9
Answer:
an = a+(n-1) d
this is the rule
Answer:
nth term = 21 - 3n
Step-by-step explanation:
18,15,12,9....
This is an arithmetic sequence.
a= first term = 18
Common difference = d = second term - first term
d = 15 - 18
d = -3
nth term = a + (n-1)d
= 18 + (n-1)*(-3)
= 18 + n*(-3) - 1*(-3)
= 18 - 3n + 3
= 21 - 3n

The base and height of a triangle are in the ratio 4: 5. If the area is 640 sq. cm, find the base and height.
Answer:
base = 32 cm , height = 40 cm
Step-by-step explanation:
ratio of base : height = 4 : 5 = 4x : 5x ( x is a multiplier )
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height ) , then
A = [tex]\frac{1}{2}[/tex] × 4x × 5x = 2x × 5x = 10x²
given A = 640 , then
10x² = 640 ( divide both sides by 10 )
x² = 64 ( take square root of both sides )
x = [tex]\sqrt{64}[/tex] = 8
Then
base = 4x = 4 × 8 = 32 cm
height = 5x = 5 × 8 = 40 cm

3,328 divided by 8 show your thinking
Answer:
416
Step-by-step explanation:
Well I know 8 x 100=800 so I did 8 x 400=3,200
Then I added 8 x 10=80 which is 3,280
and from there I did 8 x 6=48
And then what's 3,280+48=3,328 because 3,280+40=3,320 and then add 8=3,328
Hope it helps
Answer:
If we break apart 3,328 and first divide 3,000 by 8 we get 375, and then divide 328 by 8 we get 41, this helps us understand that if we divided 3,328 by 8 we would get 416

Answer:
[tex]y = 3x + 12[/tex]
Step-by-step explanation:
The rate of change is represented as the slope.
The problem is asking for a slope that is equal to 3.
y=6x-3 is incorrect, the equation is simplified and the slope is 6.
3y=2x+5 is incorrect, the slope is 2 and the equation isn't simplified.
y=3x+12 is correct, the equation is simplified and it's showing the correct slope.
