Find the missing angle measurements.
The options are :
60°, 64°, 45°, 49°, 53°
Answer:
Top right ?- 60
? above 64- 64
Bottom left- 45
Step-by-step explanation:
Triangles equal 180.
The question mark above 64, the 64 and ? are congruent so the question mark is 64.
The question mark in top right, add 64+56=120. Since triangles equal 180, subtract 180-120=60
The question mark in bottom left, add 64+71=135. Since triangles equal 180, subtract 180-135=45
Hope it helps!
The value of the three missing angles are 45°, 60°, and 64°.
We have,
From the figure,
we have vertical angles.
So,
One missing angle is 64°.
Now,
There are two triangles.
The sum of angles in a triangle is 180.
So,
56 + 64 + x = 180
x = 180 - 56 - 64
x = 60°
And,
The sum of angles in a triangle is 180.
So,
71 + 64 + y = 180
y = 180 - 71 - 64
y = 45°.
Thus,
The value of the three missing angles are 45°, 60°, and 64°.

Solve this 2 system equations 2x - y = 7 and 6x - 3y = 14
Answer:
No solution
Step-by-step explanation:
Consider the given two lines
2x-y = 7 and 6x-3y = 14
Multiply the first equation by 3
6x-3y = 21 and Ii equation is 6x-3y =14
We observe both are of the 6x-3y = k for different ks
Hence these two are parallel lines.
As parallel lines never meet these line will not meet at all.
There cannot be any solution for this system.
If we subtract 6x-3y = 21 from 6x-3y = 14, we get absurd result as
0 = 7
This confirms that this system cannot be solved.
Is this equation true, false or open? 9p+8=10p+7

TRUE
The equation 9p+8=10p+7 is a true equation as it provides a specific solution upon rearrangement and simplification which is p = 1.
Explanation:The equation you have provided: 9p + 8 = 10p + 7, is what we refer to as an equation in algebra. A way to determine if an equation is true, false or open is by attempting to solve. Firstly, let's put all 'p' terms on one side of the equation and numbers on the other. It would look like this after simplification: 10p - 9p = 8 - 7, which simplifies to: p = 1. Since we found a specific solution (p = 1), this means the equation is classified as true.

Graph the inequality y> 2x +3
Graph the inequality y> 2x +3
Solution
Step 1: To graph the inequality, we need to find a few coordinates and form the table.
Step 2: Forming the table.
Let's take x = -1 and find the value of y.
Plug in x = -1 and find the value of y.
y = 2(-1) + 3 = -2 + 3 = 1
When x = -1, the value of y is 1.
So the coordinates are (-1, 1)
Plug in x = 0 and find the value of y.
y = 2(0) + 3 = 3
The coordinates are (0, 3)
Plug in x =1 and find the value of y.
y = 2(1) + 3 = 2 + 3 = 5
The coordinates are (1, 5)
Steo 3: Now let's plot the points and draw the graph.
Since the graph is greater than, we have to draw the dotted lines and shade the region above.

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) true?
Answer:
x=1/5
Step-by-step explanation:
-5x-(7-4x)=-2(3x-4)
-5x+7+4x=6x-8
-5x+6x+4x=5x = 8-7=1
5x = 1

What is the slope and y-intercept of the equation 3(y − 2) + 6(x + 1) − 2 = 0? A. slope = -2, y-intercept = B. slope = 2, y-intercept = C. slope = -2, y-intercept = D. slope = 2, y-intercept = E. slope = -2, y-intercept =
The correct answer is that the slope is equal to -2 and the y-intercept is equal to 2/3.
To find this, follow the order of operations and solve for y.
3(y − 2) + 6(x + 1) − 2 = 0 ----> distribute
3y - 6 + 6x + 6 - 2 = 0 -----> combine like terms
3y + 6x - 2 = 0 -----> subtract 6x
3y - 2 = -6x -----> add 2
3y = -6x + 2 -----> divide by 3
y = -2x + 2/3
Now we can find the slope as the coefficient of x (-2) and the intercept as the constant (2/3)
Answer: The slope of the given line is -2 and y-intercept is [tex]\dfrac{2}{3}.[/tex]
Step-by-step explanation: We are given to find the slope and y-intercept of the following equation of a line:
[tex]3(y-2)+6(x+1)-2=0~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
the slope-intercept form of the equation of a line is given by
[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.
From equation (i), we have
[tex]3(y-2)+6(x+1)-2=0\\\\\Rightarrow 3y-6+6x+6-2=0\\\\\Rightarrow 3y+6x=2\\\\\Rightarrow 3y=-6x+2\\\\\Rightarrow y=-2+\dfrac{2}{3}.[/tex]

How to solve 2^x = 550?
2 squared X= 550
x = 550 square root
x=23.45
The solution to the equation [tex]2^x[/tex] = 550 is x ≈ 9.0959.
To solve the equation [tex]2^x[/tex] = 550, we need to isolate the variable 'x'. Here's the step-by-step process:
1. Take the logarithm (base 2) of both sides of the equation:
log2([tex]2^x[/tex]) = log2(550)
Using the property of logarithms, logb([tex]b^x[/tex]) = x, we have:
x = log2(550)
2. In this case, since we want to find x, we can use the logarithm function with base 2:
x ≈ log2(550) ≈ 9.0959
Therefore, the solution to the equation [tex]2^x[/tex] = 550 is x ≈ 9.0959.

Add 1 to both sides
19 = 5x - 1

Mrs. Santos has 24 students in her class. Five-eighths of her students have nicknames. Mr. Russo also has 24 students in his class. Only one-third of his students have nicknames. How many students from Mrs. Santos' class and Mr. Russo's class do not have nicknames?
In Mrs. Santos' class, five-eighths of the students have nicknames, meaning that three-eighths don't have nicknames. Three-eighths of 24 is 9, so 9 students don't have nicknames.
In Mr. Russo's class, one-third of the students have nicknames, meaning that two-thirds don't have nicknames. Two-thirds of 24 is 16, so 16 students don't have nicknames.
Therefore, there are 9 students from Mrs. Santos' class and 16 students from Mr. Russo's class who don't have nicknames.

Answer:
The integer represents the yards gained or lost on the next play is 9.
The required number line is shown in figure 1.
Step-by-step explanation:
Consider the provided information.
A football team lost 9 yards during a play.
Represent Lost with a negative sign.
Thus, lost of 9 yards can be written as: -9 (As shown in the provided figure)
Now it is given that the team had a combined gain or loss of 0 yards after the next play.
Let they gain or lost x score in next play.
-9 + x = 0
Add both the sides by 9
x = 9
It means team must gain 9 yards.
So, the integer represents the yards gained or lost on the next play is 9.
Now represent this on number line.
Move 9 digit right to -9.

Find the equation of the line that is perpendicular to y=-3/4x+1 and contains the point (9,12).
The equation of the perpendicular line is y= 4/3x
How to determine the line equation?The equation is given as:
y = -3/4x + 1
The slope of the above equation is;
m = -3/4
Let the slope of the perpendicular line be n.
So, we have:
n = -1/m
This gives
n = -1/(-3/4)
Evaluate
n = 4/3
The equation of the line is then calculated as:
y = n(x - x1) + y1
This gives
y = 4/3(x - 9) + 12
Evaluate
y= 4/3x - 12 + 12
Evaluate the like terms
y= 4/3x
Hence, the equation of the perpendicular line is y= 4/3x

The equation of the line that is perpendicular to the line y=-3/4x+1 and passes through the point (9,12) is y = 4/3x + 1.
Explanation:To solve your question, we first need to identify the slope of the given line. The equation y=-3/4x+1 is in the form y=mx+b, where m represents slope. So, the slope of the given line is -3/4.
But we require an equation that's perpendicular to this line, so its slope will be the negative reciprocal of -3/4, which is 4/3. Now, we have the slope of the new line, and we know it passes through point (9,12).
With that information, we use the point-slope formula, y - y1 = m (x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Here, x1=9, y1=12 and m=4/3. Substituting these values in gives us y - 12 = 4/3 (x - 9). Simplifying yields the equation y = 4/3x + 1, which is the equation of the line that is perpendicular to the given line and passes through the point (9,12).
