What is the distance between points D and F?
A. 5.4
B. 4.2
C. 3.7
D. 2.6
Answer:
ans is A.............
The required distance between points D and F is 5.4 units.
Coordinate, is represented as the values on the x-axis and y-axis of the graph
Here,
The coordinate of point D is (2, 0) and the coordinate of point F is (-3, -2).
The distance between points D and F can be evaluated by the distance formula,
[tex]DF = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
Substitute the value in the above equation,
[tex]DF = \sqrt{(2 + 3)^2 + (0 + 2)^2}\\ DF = \sqrt{25 + 4}\\ DF = \sqrt{29}\\ DF = 5.4[/tex]
Thus, the required distance between points D and F is 5.4 units.

Step-by-step explanation:
multiply 5 by 4, and get 20.
Then we multiply 1 by 8, and get 8.
8 × 4 = 32 that give the terms new denominators
20 32
−− −−

the school cafeteria is offering a choice of two side dishes at lunch today either watermelon or french fries the ratio of the number of orders of french fries to the total number of side dishes ordered is 9:14
A: there are 9 orders of french fries for every 14 orders of watermelon
B:there are 5 orders of watermelon for every 9 orders of french fries
C: there are 14 orders of french fries for every 9 orders of watermelon
D: there are 5 orders of french fries for every 9 orders of watermelon
Answer:
B
Step-by-step explanation:
Here, we are to select the best option that defines the ratio given in the question;
From the question, we are told that the ratio of french fries to the number of side dishes ordered is 9:14
Since 9 represents the french fries, then the ratio representing water melon orders will be 14-9 = 5
Hence, the ratio of french fries orders to water melon orders will be 9:5
The correct option is thus;
There are 9 orders of french fries for every 5 orders of watermelon
Or
There are 5 orders of watermelon for every 9 orders of french fries

Which linear equation has a slope of 3 and a y-intercept of -2
y=3x +2
y=3x - 2
y=-2x + 3
y=2x - 3
Answer:
y=3x‒2
Step-by-step explanation:
y=3x‒2 in this equation slope is 3 cause slope is the number that is a coefficient of x.
&also the y-intercept of the equation is ‒2. y=3(0)‒2
y=0‒2=‒2
cause to find y-intercept is to substite 0 instead of x &to solve

His unit rate is mile(s) per hour.
Answer:
Slope = ⅘
Unit rate = 0.8 mile per hour
Step-by-step explanation:
The slope of the graph is simply the constant rate of change along the line of the graph or change in y-coordinates of two points divided by change in their corresponding x-coordinate.
For the graph given, distance (miles) is the y-variable, while time (hours) is the x-variable.
Given that Jorge travels 4 miles for every 5 hours, therefore, the slope of the graph plotted can be represented as [tex] \frac{4}{5} [/tex]
The unit rate would be 4:5 = ⅘ = 0.8 mile per hour.
Identify which shapes on the graph are congruent to shape I by performing these sequences of transformations on shape I:
a 90° clockwise rotation about the origin and then a reflection across the x-axis
• a 90° counterclockwise rotation about the origin and then a reflection across the x-axis
• a 180° rotation about the origin and then a translation right 4 units
The shapes on the graph that are congruent to shape I by performing these sequences of transformations are as detailed below
How to Identify the Congruent Shapes?We are told that the transformations are;
a 90° clockwise rotation about the origin and then a reflection across the x-axis;
a 90° counterclockwise rotation about the origin and then a reflection across the x-axis;
a 180° rotation about the origin and then a translation right 4 units;
Now, looking at shape I;
a 90° clockwise rotation about the origin and then a reflection across the x-axis will give us the third shape at the bottom.
A 90° counterclockwise rotation about the origin and then a reflection across the x-axis; will give us the first shape at the bottom.
A 180° rotation about the origin and then a translation right 4 units will give us the last shape on the right top.

2x + 5(y - 1) when x=8 and y=5
Answer:
Your answer would be 36
Step-by-step explanation:
First you start off by rewriting the equation to make it simpler for you to understand all of the steps.
2x + 5(y-1)Then you plug in your given values. (x = 8 and y = 5)
2(8) + 5(5-1)After you plug in your given values you solve all your parenthesis (aka using the Distributive Property of Equations to simplify your equation.)
16 + 20After that, you have basic math
16 + 20 = 36And now your answer is 36.
I hope this helps you :)
The solution of the expression 2x + 5(y - 1) when x=8 and y=5 is 36
From the question, we are to evaluate 2x + 5(y - 1) when x=8 and y=5
To do this, we will put the given respective values of x and y into the expression 2x + 5(y - 1)
That is,
2x + 5(y - 1) becomes
2x + 5(y - 1) = 2(8) + 5(5-1)
= 16 + 5(4)
= 16 + 20
= 36
Hence, the solution of the expression 2x + 5(y - 1) when x=8 and y=5 is 36

Answer:
Step-by-step explanation:
Ok
Step-by-step explanation:
when trying to find the inverse of a function just replace x with y and try to make the y the subject of the formula.
x = 1/2(y) + 1
x+1 = 1/2 (y)
2(x+1) = y

Answer:
Option (3)
Step-by-step explanation:
From the picture attached,
Area of the green shaded region = Area of triangle ADC + Area of triangle ABE
Area of triangle ADC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AD)(DC)[/tex]
= [tex]\frac{1}{2}(12)(8)[/tex]
= 48 square units
Area of triangle ABE = [tex]\frac{1}{2}(AB)(BE)[/tex]
= [tex]\frac{1}{2}(12)(8-3)[/tex]
= 30 square units
Area of green shaded region = 48 + 30 = 78 square units
Option (3) will be the answer.
