Answer:
A
Step-by-step explanation:
The solution we're looking at here is a set of all the points between two parallel lines. Let's see what we can find out about those lines from the inequality, and use that the pick the correct option.
We can start by splitting the inequality at the top into two seperate inequalities:
[tex]7\leq y-3x<11\\y-3x\geq7\\y-3x<11[/tex]
From here, we can put each inequality into slope-intercept form:
[tex]y\geq3x+7\\y<3x+11[/tex]
Our slope for both lines is positive, so we can immediately eliminate B and D. A and C both display lines with slopes of 3 and y-intercepts of 7 and 11; the only difference is in which line is dashed and which line is solid.
As a reminder, a dashed line means that the line itself is not included in the solution, a solid line means that it is. Dotted lines always pop up when you see the symbols < and >, while solid lines pop up when you see ≤ and ≥.
[tex]y\geq3x+7[/tex] (Solid)
[tex]y<3x+11[/tex] (Dashed)
This matches up very nicely with the graph in A, our solution.

Answer:
The steps will be :
1. Draw both equations into the graph.
2. Look for the coordinates where they intersect(curve and line crosses each other). So the coordinates will be (-2,0) and (3,5).
3. The x-value of the coordinates will the solution to the equations.

Which expression is equivalent to (7 – 3k) – (4 – 5k) – (6 – 2k)?
Answers
Answer:
The right response is "[tex]3(k-1)[/tex]". A further solution is given below.
Step-by-step explanation:
The given expression is:
⇒ [tex](7 -3k) - (4 - 5k) - (6 - 2k)[/tex]
On solving the above expression, we get
⇒ [tex]7-3k-4+5k-6+2k[/tex]
⇒ [tex]7-3k-10+7k[/tex]
⇒ [tex]3k-3[/tex]
On taking "3" as common, we get
⇒ [tex]3(k -1 )[/tex]
10.ABCD is a rhombus such that measure of angle ACB is 40º find the measure of angle ADC.
Answers
Answer:
ADC = 100 degrees
Step-by-step explanation:
Please check attachment for diagrammatic representation of the Rhombus
From what we can see in the diagram;
angle CBD and CDB are equal
The reason for this is that we have an isosceles in triangle CBD
CBD = 90- ACB
CBD = 90-40 = 50
We need ADB to completely calculate ADC
CAB is also 40 from the isosceles ABC
That means DBA = 90 - CAB = 90-40 = 50
So from isosceles ABD, we have that ADB is also 50
Mathematically;
ADC = ADB + DBA
ADC = 50 + 50
ADC = 100
use distributive property to write an expression 0.4(-5-7y-13.8)
Answers
Answer: -2.8y - 7.52
The simplified form of the expression is -2.28y - 7.52.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is a number used before a phrase.
Given:
An expression,
0.4(-5-7y-13.8).
Solving the expression with the help of distributive property,
0.4 x -5 - 0.4 x 7y - (0.4 x 13.8).
= -2 -2.8y - 5.52
= -2.28y - 7.52
Therefore, -2.28y - 7.52 is the solution.

isosceles and equilateral triangles (please help me as fast as you can thank you)
Answers
Answer:
x = 71°
x = 19°
x = 34°
Step-by-step explanation:
In rectangle ABCD. By exterior angle theorem:
x + 65° = 46° + 90°
x + 65° = 136°
x = 136° - 65°
x = 71°
Since, XYZ is an equilateral triangle,
Therefore, m(angle XZY) = 60°, So, by exterior angle theorem:
m angle XZY = x + 41°
60° = x + 41°
60° - 41° = x
19° = x
x = 19°
PQR is an isosceles triangle. In which PQ = PR.
Therefore,
m(angle PRQ) = m(angle PQR) = 69°

x = 69° - 35°
x = 34°

Answers
Answer:
C
Step-by-step explanation:
the range is all the possible numbers on the Y axis. We can see that the graphs peaks at 3 and then goes down both ways. This means that eventually the y axis will be equal to all real numbers less than 3
The range of the function looks to be all real numbers less than or equal to -1, according to the provided graph. The best choice is B.
What is a range of a function?This is due to the fact that the graph's horizontal line at y=-1, which shows that the function accepts all values less than or equal to -1, stretches eternally in both directions.
The collection of all potential output values that a function can take on is generally referred to as the function's range. You can look at the vertical spread of the graph to see what values the function can take on in order to determine the range of a function from its graph.
Observe that the accompanying graph features a horizontal line at y=-1 that spreads out infinity in both directions. This indicates that for all values of x, the function takes on the value of -1.
The graph also features a vertical line at x=2 that goes on forever in both directions, as can be seen. This shows that the function can accept any value of y for x=2.
Combining these findings, we can determine that the function has a range of all real numbers less than or equal to -1 since it takes on the value of -1 for all x and the range of potential values of y is unrestricted.
