Answer:
8 mph
Step-by-step explanation:
The lorry's shortest route:
60 miles in 1.5 hours
speed = distance/time = (60 miles)/(1.5 hours) = 40 mph
The longer route:
time = 1.5 hours
distance = 20% more than 60 miles = 1.2 * 60 miles = 72 miles
speed = distance/time = (72 miles)/(1.5 hours) = 48 mph
Difference in speeds: 48 mph - 40 mph = 8 mph
I’m stuck on this math problem
Answer:
C.
Step-by-step explanation:
You can eliminate A and B because they square root graphs. You are left with C and D. C is the correct choice because the graph is being reflected across the x-axis, shown by the negative.
Alternatively you can graph each equation on a graphing calc and choose the best answer.

Which algebraic expression represents the phrase “ the quotient of negative right and the sum of a number and three”?
Answer:
-8 ÷ (x + 3)
Step-by-step explanation:
So quotient means that you're dividing, so put a ÷
Next, it says the dividend, or the part being divided is -8, so now you have this: -8 ÷
Lastly, it says the divisor, or the part doing the dividing, is a quantity equal to the sum of "some number" (we'll use x) and 3. Since the divisor is one quantity collectively, you have to put it in parentheses.
This gives you: (x + 3)
When you put it all together, you get -8 ÷ (x + 3).
This can also be written as a fraction: -8/x+3.

To break even Lucas needs to sell 200 ribbons --> this is because, =>
let's make an expression for this equation -->
x = amt. of ribbons
y = expense or revenue
x(0.25) = y + x(0.02)
Let's plug he given in --> 0.25x = 46 + 0.02x -->

what is the area of the obtuse triangle given below
Answer:
The answer is A
Step-by-step explanation:
The formula used to find the area of a triangle is 1/2base *height
The base is 16 so half of 16 is 8 then multiply it with the height 8 to get 64.
Area of obtuse triangle is 64 sq. units
What is obtuse triangle?"A triangle whose any one of the angles is an obtuse angle or more than 90 degrees, then it is called obtuse-angled triangle or obtuse triangle."
Given
Base of triangle = 16
Height of triangle = 8
Formula to find the area of obtuse triangle
A = [tex]\frac{1}{2}[/tex] × [tex]base[/tex] × [tex]height[/tex]
A = [tex]\frac{1}{2}[/tex] × [tex]16[/tex] × [tex]8[/tex]

Complete the table of ordered pairs for the given liners equation
Answer:
Step-by-step explanation:
Given equation of the line is,
y = -x + 1
We will get the output values (y-values) from the given equation for different input values (x-values).
For x = 0,
y = 0 + 1
y = 1
For x = -1,
y = -1 + 1
y = 0
For x = -6,
y = -6 + 1
y = -5
So the table of the ordered pairs will be,
x 0 -1 -6
y 1 0 -5

Answer:
y = -7
Step-by-step explanation:
As the slope is m = 0, that means there is no slope. All values of x in the domain will always output -7. Therefore, your equation would be y = -7.
Answer:
y = -7
Step-by-step explanation:
Use the formula:
y = mx + b
Where m is the slope and b is the y-intercept.
The slope of the equation is equal to 0.
The y-intercept is at (0, -7)
y = (0)x + -7
y = -7
The equation of the line is y = -7.

Find the x.
Answer:
10
Step-by-step explanation:
1. Write an equation to represent the ratio of the sides to the corresponding sides in the second figure.
6/9 = x/15
6 and x are both numerators because they are corresponding sides and 9 and 15 are both numerators because they are corresponding sides.
2. Solve for x.
multiply both sides by 9
6 = 9x/15
multiply both sides by 15
90 = 9x
solve for x by dividing both sides by 9
x = 10

In STU, SU =18 and TU =13. Find m
Answer:
m=22.2
Step-by-step explanation:
By using the Pythagorean’s theorem i.e
hypotenuse^2=opposite^2+adjacent^2
Where
Hypotenuse =unknown
Opposite =18
Adjacent =13
Hyp^2=18^2+13^2
Hyp^2=324+169
Hyp^2=493
Hyp=sqrt 493
Hyp=m=22.2
Find the slope of the line that passes through (-38, 100) and (-37, 5).
The slope between two points is: (change in Y) / (change in X) .
Slope = (-95) / (1)
Slope = -95
Step-by-step explanation:
[tex](-38, 100) and (-37, 5). \\ x1 = - 38 \\ y1 = 100 \\ x2 = - 37 \\ y2 = 5[/tex]
[tex]m \: = \frac{y2 - y1}{x2 - x1} \\ m \: = \frac{5 - 100}{ - 37 - 38} \\ m = \frac{ - 95}{ - 75} [/tex]

Use △XYZ, in which ∠X is a right angle and tanY=815.
Answer:
8/17
Step-by-step explanation:
The correct and complete question is:
Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?
From definition:
tan(Y) = opposite/adjacent
From the graph and the question:
tan(Y) = XZ/XY = 8/15
Then:
XZ = 8 and XY = 15. Using pytaghorean theorem:
XZ² + XY² = YZ²
8² + 15² = YZ²
√289 = YZ
17 = YZ
From definition:
sin(Y) = opposite/hypotenuse
From the graph:
sin(Y) = XZ/YZ
sin(Y)= 8/17
Find dy/dx by implicit differentiation for x – y = xy.
Answer:
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]
Step-by-step explanation:
Differentiate xy using the product rule, then
Given
x - y = xy
1 - [tex]\frac{dy}{dx}[/tex] = x. [tex]\frac{dy}{dx}[/tex] + y. 1 = x[tex]\frac{dy}{dx}[/tex] + y ( subtract 1 from both sides )
- [tex]\frac{dy}{dx}[/tex] = x [tex]\frac{dy}{dx}[/tex] + y - 1 ( subtract x [tex]\frac{dy}{dx}[/tex] from both sides )
- [tex]\frac{dy}{dx}[/tex] - x [tex]\frac{dy}{dx}[/tex] = y - 1 ( multiply through by - 1 )
[tex]\frac{dy}{dx}[/tex] + x[tex]\frac{dy}{dx}[/tex] = 1 - y
[tex]\frac{dy}{dx}[/tex] (1 + x) = 1 - y ← divide both sides by (1 + x)
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1-y}{1+x}[/tex]
The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).
What is differentiation?Differentiation is a method of finding the derivative of a function.
It shows instantaneous rate of change in a function.
The given expression is,
x - y = xy
Differentiate with respect to x,
d/dx (x-y) = d/dx (xy)
Use multiplication formula for differentiation,
d/dx(ab)= a.db/dx+da/dx.b,
1 - dy/dx = x.dy/dx + y. 1
1 - dy/dx = x.dy/dx + y
1 - y =x.dy/dx + dy/dx
1 - y = (x+1).dy/dx
dy/dx = (1-y)/(x+1)
The differentiation of the function x - y = xy is dy/dx = (1-y)/(x+1).

Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9

What is the equation of a line with a slope of -3 and a y-intercept of 4
Answer:
y = -3x + 4
Step-by-step explanation:
So the -3 is the slope and the slope always has an x and the y intercept is b which is 4
Answer:
y = -3x + 4
Step-by-step explanation:
slope-intercept form: y = mx + b
Note that: m = slope
y- intercept = b
m = slope = -3
y-intercept = b = 4
Plug in the corresponding number to the corresponding variables:
y = mx + b
