Write down the equation of a line whose slope is -7 and crosses the y-axis at 7. Express in slope-intercept form.
Answer:
y= -7x+7
Step-by-step explanation:
y= mx+b
y= slope x+ y intercept
The equation of the line having the slope -7 and y-intercept is 7 is: y = -7x + 7
What is the equation of line?A straight line's equation is a relationship between its x and y coordinates, and it is written as y = mx + c, where m is the line's slope and c is its y-intercept.
We are given that the slope m is -7,
and the line crosses the y-axis at 7.
so the value of c = 7
Therefore, we can substitute these values into the slope-intercept form to get:
y = -7x + 7
So the equation of the line is y = -7x + 7.

Ellie took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.50 plus $5 per mile. The total fare was $76,50, not including the tip. Write and solve an equation which can be used to determine m, the number of miles in the taxi ride.
I dont understand this
Answer: 1.50+5m=76.50 m=15
Step-by-step explanation:
The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
pick-up fee = $1.50 plus $5 per mile
Since, m is the number of miles in the taxi ride
So, equation for pick-up fee for m miles,
pick-up fee = $1.50 + $5m
Now total fare = $76,50
Thus, required equation to determine m is given as,
1.50 + 5m = 76.50
Subtracting 1.5 both the side we get,
1.50 + 5m - 1.5 = 76.50 - 1.5
⇒ 5m = 75
or, m = 75/5
⇒ m = 15
Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

Which function is best represented by the graph?
Which is the solution for ln(3x - 5) = ln(11) + ln(2) ?
Answer:
B: x=9
Step-by-step explanation:
You have to use the property of logarithms
that says ln A + ln B = ln AB. So here we have
ln (3x - 5) = ln 11 + ln 2 = ln 22
Therefore 3x - 5 = 22, from which x = 9

Find the measure of each side indicated. Round to the nearest tenth.
Answer:
Step-by-step explanation:
to find x we can use tangent function
tan 31= x/9
0.60=x/9
x=0.60*9=5.4 choice B
The measure of x side.
We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.
We have to determine the value of x.
Therefore we use here the trigonometric ratio
What is the tan ratio?[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]
Therefore we get
tan 31= x/9
tan(31)=0.60
0.60=x/9
Isolate the x
x=0.60*9
x=5.4
Therefore option B is correct.

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1

Which function has an inverse that is a function?
b(x) = x2 + 3
d(x) = –9
m(x) = –7x
p(x) = |x|
Answer:
All but the second one
Step-by-step explanation:
Find the inverse of each function:
b(x)=x^2+3
y=x^2+3
x=y^2+3
x-3=y^2
sqrt(x-3)=y
This inverse function is a function
d(x)=-9
y=-9
This doesn't have an inverse function
m(x)=-7x
y=-7x
x=-7y
-1/7x=y
This inverse function is a function
p(x)=|x|
y=|x|
x=|y|
x=y
This inverse function is a function
Therefore, all but the second function have inverses that are functions
Answer:
All but the second one have inverse functions
