Answer:
The parallel line should be y = 2x + 7
The equation of the line that passes through the point (8,-1) and is parallel to the line y = 2x – 4 is; y = 2x + 7
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope,
m= 2
We know that Point-Slope Form:
y - y₁ = m(x - x₁)
Point (-2,3)
Then Slope m = 2
Now Write the equation as;
y - 3 = 2(x + 2)
This means the final equation is;
y = 2x + 7

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

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.

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.

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

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]
