Figure A is a scale image of Figure B.
What is the value of x?
Answer:
The required value of x is 12 units.
Step-by-step explanation: Given that the figure A is a scale image of figure B.
We are to find the value of x.
Since figure A is the scale image of figure B, so both the figures are similar to each other.
Also, the corresponding sides of the similar figures are proportional, so we get
Thus, the required value of x is 12 units.
Find the formula for an exponential function that passes through the two points given.
(0,7) and (4,567)
Answer:
[tex]y = 7(3^x)[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,7)[/tex]
[tex](x_2,y_2) = (4,567)[/tex]
Required
Determine the formula
An exponential function is of the form:
[tex]y = ab^x[/tex]
For point [tex](x_1,y_1) = (0,7)[/tex]
[tex]7 = ab^0[/tex]
[tex]7 = a*1[/tex]
[tex]7 = a[/tex]
[tex]a = 7[/tex]
For point [tex](x_2,y_2) = (4,567)[/tex]
[tex]567 = ab^4[/tex]
Substitute 7 for a
[tex]567 = 7*b^4[/tex]
Divide both sides by 7
[tex]81 = b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{81} =\sqrt[4]{b^4}[/tex]
[tex]\sqrt[4]{81} =b[/tex]
[tex]b = \sqrt[4]{81}[/tex]
[tex]b = 3[/tex]
Substitute 7 for a and 3 for b in [tex]y = ab^x[/tex]
[tex]y = 7 * 3^x[/tex]
[tex]y = 7(3^x)[/tex]

Uber is now charging a $2.50 flat rate in addition to $0.75 per mile for your ride. Janae can spend at most $13 on her Uber Ride. Which answer choice below represents the number of miles Janae can travel without exceeding her budget?
A:22
B:10
C:30
D:18
Answer:
B: 10Step-by-step explanation:
Full charge can be expressed as equation:
c = 2.5 + 0.75m, where c- charge, m- milesThe limit for charge is $13, then we got inequality:
0.75m + 2.5 ≤ 130.75m ≤ 9.5m ≤ 9.5/0.75m ≤ 12.66Option B: 10 is correct as the only number satisfying the inequality
Answer:
B:10

someone please help me!!!!!
Explanation:
Each time x goes up by 1, y goes up by 18
slope = rise/run
slope = (change in y)/(change in x)
slope = 18/1
slope = 18
You can also use the slope formula to get the same answer. Let's say we picked the points (2,36) and (3,54). We then would get
m = (y2-y1)/(x2-x1)
m = (54-36)/(3-2)
m = 18/1
m = 18
We get the same result as before.
Since x represents the number of years and y is the number of inches, the slope of 18/1 indicates an increase of 18 inches per 1 year, or just 18 inches per year.
A large shipment of batteries (several million) contains 4% that are defecttive.It 60 batteries are selected randomly,What is the probability that at most two are defective?
Answer:
0.5676
Step-by-step explanation:
We have been given these informations from this question ,
probability of 4% = 0.04
q = 1 - p = 1 - 0.04 = 0.96
Sample size n = 60
We solve further by Using binomial probability formula,
P(X = x) = (nCx)*px*(1 - p)^n - x
We have:
(60C0)x 0.04⁰x(0.96⁶⁰+(60C1)x0.04¹x(0.96)⁵⁹+(60C2)x0.04²x (0.96)⁵⁸
From this we would get the probability to be = 0.5676

The ratio of two computers is 3:2.
1.If the first computer costs 55000/=,what is the price of the second computer?
2.If the price of 2nd computer is 2000/= more,what is the ratio of. the computers?
Answer:
1. $82,500
2. 169 : 110
Step-by-step explanation:
The computation is shown below:
Given that
1. Ratio between two computers is 3:2
And the first computer cost is $55,000
Let us assume the price of the second computer be x.
As we know that
Product of extremes = Product of mean.
2 : 3 :: 55000 : x .
Now cross mutiplication is to be done
2x = $55,000 × 3
x = $1,650,000 ÷ 2
= $82,500
2. Now if the price of the 2nd computer rised by $2,000
So the new cost would be
= $82,500 + $2,000
= $84,500
Now the ratio would be
= $55,000 : $84,500
= 169: 110

Answer:
The slope is -2 and the slope-intercept form is y=-2x+20
Step-by-step explanation:
To find the slope between two points, remember to use the equation y2-y1 over x2-x1. That will help you get the slope. To find the y-intercept, use any of the two points given and insert the slope into the equation y=mx+b. For this one I used the two points (7,6)

Graph the following equations on the graphs below.
( GRAPHING PAPER NEEDED, NOT A WEBSITE )
First, you want to identify the slopes and y-int.
Equation 1 = y = -2x + 2
Slope = -2
y-int. = 2 or (0,2)
Equationt 2 = y = 2x + 3
Slope = 2
Y-int. = 3 or (0,3)
To graph, first plot the y-intercepts. Then do the slopes.
Slope = -2
Down 2 over 1 (to the right)
Slope = 2
Up 2 over 1 (to the right)
Then just connect the dots in a line!
