Answer:
19, 18, 15.5
Step-by-step explanation:
To solve this problem, you need to substitute the given values into the function.
b(x = -2) = 18 - 0.5(-2) = 18 + 1 = 19
b(x = 0) = 18 - 0.5(0) = 18 - 0 = 18
b(x = 5 ) = 18 - 0.5(5) = 18 - 2.5 = 15.5

the sum of three numbers is 20
the first is 4 times the sum of the other two
the second is seven times the third
what is the product of all three
Answers
Answer:
A*B*C= 28
Step-by-step explanation:
A+B+C=20
1. A = 4(B+C)
2. B = 7C
3. C = C
----------------------
1.
A = 4( 7C + C )
A=4(8C)
A= 32C
---------------------
A+B+C=20
32C + 7C + C = 20
40C = 20
C = 20/40
C = 1/2
------------------------
A= 32(1/2) = 32/2 = 16
B= 7(1/2) = 7/2
C= 1/2
A*B*C = 16 * 7/2 * 1/2
A*B*C= 28

Answers
Answer:
It should be c
Step-by-step explanation:
Your formula is
Number of color ball/total ball
so 8/20 x 7/19 x 3/18 then convert to fraction
The probability the first ball is red is 0.4 or 8/20 or 2/5
The probability the next is blue is 7/19
The probability of the next being white is 6/18 or 1/3.
Multiply them together because these are independent events that must all occur and we get 2*7*1= 14 as the numerator
5*19*3=285 for a total probability of 14/285.

Hello there!
When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.
Rise=How many units we move up (here, the rise is 3)
Run=How many units we move left or right (Here, the run is 5)
So the slope of this line is [tex]\frac{3}{5}[/tex]

A. y=5.5x+6.75
B.y=13.5x-1.25
C.y=13.5x+12.25
D.y=6.75x+5.5
Answers
Answer:
D. y = 6.75x + 5.5Step-by-step explanation:
The slope intercept form:
y = mx + b, where m- slope, b- y-interceptUse two ordered pairs from the table and work out the equation.
(1, 12.25) and (3, 25.75)Find the slope:
m = (y₂ - y₁)/(x₂ - x₁)m = (25.75 - 12.25)/(3 - 1) = 13.5/2 = 6.75Find the y- intercept:
12.25 = 6.75*1 + bb = 12,25 - 6.75b = 5.5The equation is:
y = 6.75x + 5.5Correct choice is D
Slope
m=(25.75-12.25)/3-1m=6.75Equation in point slope form

The graph of [tex]y = \frac 34x +5[/tex] has a slope of 3/4 and a y-intercept of 5
The linear equation is given as:
[tex]y = \frac 34x +5[/tex]
Set x = 0
[tex]y = \frac 34 * 0 +5 = 5[/tex]
Set x = 1
[tex]y = \frac 34 * 1 +5 = 5\frac 34[/tex]
Set x = 2
[tex]y = \frac 34 * 2 +5 = 6\frac 12[/tex]
The above means that, the graph of [tex]y = \frac 34x +5[/tex] passes the following points

A 3m wide road runs around a circular park whose circumference is 132m . Find the cost of fencing the outer boundary of the road at the rate of $10 per m
Answers
Answer:
$ 1508.57 and please give brainliest
Step-by-step explanation:
The road around the park = 3 m wide,
and the circumference of the park = 132 m,
We have to find the cost of fencing
the outer boundary,
the rate = $10 per m
Step-by-step explanation:
As we know that the circumference
of a circle = 2 × 22÷7 × radius
2 × 22÷7 × radius = 132 m,
44 × radius = 132 m × 7,
44 × radius = 924 m,
radius = 924 ÷ 44 m
So, radius = 21 m ( smaller circle )
radius = 21 m + 3 m ( larger circle )
= 24 m
Usually, we fence on the borders means it's
the circumference of the larger circle
= 2 × 22÷7 × radius
= 44÷7 × 24 m
= 1056÷7 m
= 150.85 m
cost of fencing = $ 10/m
total cost = 150.85 × $ 10
= $ 1508.57

Answer:
A) 23+x = 35
x = 12
Step-by-step explanation:
The question is asking you to find the equation and variable that best represents the scenario. We know that Emily had 35 dollars and had 7 dollars after paying for everything. This means that 7 plus what she spent must equal 35. However, we only know the cost of the ticket. So, add the cost of the ticket to the money left to figure out part of the equation. This equals 23 dollars. Therefore, whatever is left must be what she spent on lunch. So, the equation should look like 23 + x = 35. This is because the $23 is the ticket/the amount left and the x is the cost of lunch. Together they equal what Emily brought to the fair.
