Answer:
they add up to 75 degrees
Step-by-step explanation:
the interior angles of a triangle always have to total to 180 degrees, so if one of them is 105 the other two are 180 - 105 = 75 degrees
Answer:
Each angle could possibly be 37.5
Step-by-step explanation:
the sum of all the angles inside a triangle is 180 degrees. If one angle is 105, then we take 105 from 180
180 - 105 = 75
75 is the measure of all the missing angles. since there are two missing angles, we can divide 75 by two for the two angles
75 divided by two is 37.5
The first equation in a system is 5x + 2y = –4. Which equation gives a system with no solution? A. y = 2x + 6 B. y = 1/4x – 2 C. y = 2x + 7 D. y = –5/2x – 3
Given:
The first equation of the system of equations is
[tex]5x+2y=-4[/tex]
To find:
The equation that gives a system with no solution.
Solution:
We have,
[tex]5x+2y=-4[/tex]
It can be written as
[tex]2y=-5x-4[/tex]
[tex]y=\dfrac{-5x-4}{2}[/tex]
[tex]y=-\dfrac{5}{2}x-2[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=-\dfrac{5}{2},b=-2[/tex]
It means the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is -2.
Slope of parallel lines are same but the y-intercepts are different.
From the given options, the slope of the line is [tex]-\dfrac{5}{2}[/tex] only in option D and the y-intercept is -3 which is different from -2.
The line [tex]y=-\dfrac{5}{2}x-3[/tex] is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is [tex]y=-\dfrac{5}{2}x-3[/tex].
Therefore, the correct option is D.
Find the value of b + 19 when b=9.
Answer:

(9) + 19 =
9 + 19 = 28
Answer:
28
Step-by-step explanation:
Substitute b with 9 so it's 19 + 9 = 28

Answer:
the picture has the answer (4y , 2.5x)
Step-by-step explanation:
Answer:
y = 7
Step-by-step explanation:
Locate x = - 5 on the x- axis, go vertically up to meet the graph at (- 5, 7)
Thus when the input is x = - 5, the output is y = 7
Alex is y years old. Bella is 4 years older than him .Carla is double Alex's age. The sum total of their age is 32
Form and solve an equation to work out the ages of the three children
Answer:
Alex is 7, Bella is 11, and Carla is 14
Step-by-step explanation:
Equation is 32=y+2y+(y+4)
To solve:
First combine like terms (the y's)
32=4y+4
Subtract 4 from both sides
28=4y
Divide both sides by 4 to get y alone
7 =y (Alex's age)
Bella is 4 years older than Alex so 7+4 = 11
Carla is 2 times older than Alex so 2 • 7 = 14
Their ages are supposed to add up to 32.
7+11+14
18+14
32
A function is given: f (x) = 2x + 3
What is the value of f(-2)?
Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
A collection of all points in the plane of the form (x, f(x)) is the graph of a function f. The graph of f is defined as the graph of the equation y = f(x).
Find function:[tex]\to f (x) = 2x + 3[/tex]
[tex]\to f(-2) =?[/tex]
Putting the value "-2 " into the above given method:
⇒ f(-2) = 2(-2) + 3
⇒ f(-2) = -4 + 3
⇒ f(-2) = -1

i need help hurry!!!!!!!! solve for x
Answer:
Original Equation: 10x-8/3-4x=6x
Add 4x to both sides: 10x-8/3=10x
Subtract 10x from both sides: -8/3=0
However, we know that -8/3 does not equal to 0, so there is no solution.

Ivan wants to rent a boat and spend less than $31. The boat costs $8 per hour, and Ivan has a discount coupon for $9 off. What are the possible numbers of
hours Ivan could rent the boat?
Write your answer as an inequality solved for t.
Answer:
he could have the boat for 4 hours with the coupon
t or time is the unknown here to be solved.
The hours Ivan rent the boat multiplied with $8 with $9 discount needs to be less than $31. Hence,
8t - 9 < 31
8t < 31 + 9
8t < 40
t < 5
The hours Ivan can rent the boat has to be less than 5. This is because he wants to spend LESS than 31, 31 sharp is not okay.

g(x) is the function from the table which gives values that could come from the exponential function.
What is a function?A relation is a function if it has only One y-value for each x-value.
We have to find the function from the table which gives values that could come from the exponential function.
The exponential function is a mathematical function denoted by .
As we observe the g(x) function.
When x =1, g(x)=2
x=2, g(x)=4
x=3, g(x)=8
g(x)=2ˣ is the required function which is in exponential form
Hence, g(x) is the function from the table which gives values that could come from the exponential function.

Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. Use the graph to find the range.
Step-by-step explanation:
Explanation: y=7 is a straight line with zero slope and y-intercept 7 as shown below. Hence its domain (all allowed x-values) is all real numbers, and its range (all allowed y-values) is only 7.
