A line passes through the point (-2, -7) and has a slope of5/2
Write an equation in slope-intercept form for this line.
Answer:
y=5/2x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=5/2(x-(-2))
y+7=5/2(x+2)
y=5/2x+10/2-7
y=5/2x+5-7
y=5/2x-2

Answer:
[tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]
Step-by-step explanation:
We use the properties of logarithms to write this as a single logarithmic expression. First the exponent property:
2 log(a) + 4 log(b) - log(c) - 3 log(d) =
= log(a^2) + log(b^4) - log(c) - log(d^3) =
and now the multiplication and division properties
= [tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]

Evaluate. (82 - 42) . (1/4)2
Answer:
20
Step-by-step explanation:
The equivalent value of the expression is A = 2.5
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 82 - 42 ) ( 1/4 )²
On simplifying the equation , we get
A = ( 40 ) ( 1/16 )
A = 40/16
A = 2.5
Hence , the expression is solved and A = 2.5

The new computer you want to buy costs $749.50. If you wait for it to go on sale for 17% off, what will the sale price be?
Answer:
$622.09
Step-by-step explanation:
The computer is $749.50 and if the computer is 17% off, it means that you only need to pay 83% of the original cost.
749.50/100 = 74.95
74.95*83 = $622.085
Since the thousandth is a 5, round up to $622.09
The sale price is $622.09

Quadratic Transformations (photo down below)
Answer: b
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Because the transformation of the quadratic equation is outside of parentheses, it can be concluded that the line is either above or below each other. Next, since we are determining how much higher of lower f(x) is according to g(x), we can determine that it is above since the f(x) is a + and g(x) is a -.

What is the slope of the line
Write an equation in point-slope form of the line that passes through the two given points. Use the point (5,1) to write the equation.
(4, 7) and (5, 1)
A. y + 1 = 6(x-5)
B. y + 1 = 6(x+5)
C. y - 1 = -6(x-5)
D. y + 1 = -6(x-5)
Answer:
c.
Step0-by-step explanation:
you can plug both points into the equations
or you can just write it out using the point slope equation y-y₁=m(x-x₁)
plug in (5,1)
y₁=1 x₁=5
slope is difference of y/difference of x
m=(7-1)/(4-5)=-6
plug in to y-y₁=m(x-x₁) and you get
y - 1 = -6(x-5)

PLEASE HELP ASAP! Determine whether each graph represents a direct variation relationship
Answer:
1. Yes, it does not have a y-intercept, but has slope.
2. No, it has y-intercept.
Step-by-step explanation:
A direct variation relationship has to be able to fill in the equation y=mx. Any direct variation relationship cannot have a y-intercept in it. Therefore, question 1 is a direct variation relationship and question 2 is not a direct variation relationship.
Solve 2x - 3 = 1 help please
Answer:
first add 3 to both sides to get rid of the three on the left side
2x = 4
then divide 2 from both sides since it is the opposite of the operation shown then you'll get x = 2 when dividing to on the left side you get rid of it because you are trying to get rid of as much of the numbers as possible.
Answer:
X=2
Step-by-step explanation:
1). cancel the -3 out on both sides of the equation
2). When you add together the 1 and 3, you will recieve the value of 4
3).In order to get the x attached to the coefficient 2 isolated you have to divide 2 on both sides
4.) 2x = 4
5). 2x/2 = x
6). 4/2 = 2
Therefore x=2

Genny is making bracelets for her friends. She can make 3 bracelets in 15 minutes. How long will it take Genny to make a bracelet for all 10 of her friends?
Answer:
50 minutes
Step-by-step explanation:
15 / 3 = 5
5 x 10 = 50
Answer
50 minutes
Step-by-step explanation:
If Genny makes 3 bracelets in 15 minutes, she can make 9 bracelets in 45 minutes.
9/3 = 3
3 x 15 = 45 minutes
She needs to make one more bracelet. It takes 5 minutes to make one bracelet because: 15/3 = 5/1 (Five minutes = One bracelet)
45 mins + 5 mins = 50
