Answer:
E) (0, 1)
Step-by-step explanation:
We can equalize the first two equations to find a certain point they share. We can then check if the third line also passes through this point if substituting that point's x coordinate into the third line's equation returns the point's correct y value.
[tex]2x + 1 = 3x + 1 \\\to 0 = x[/tex]
Therefore, the point is (0, 1) as substituting [tex]x = 0[/tex] into the first equation returns [tex]y = 1[/tex].
Substituting [tex]x = 0[/tex] into the third equation does also return [tex]y = 1[/tex], therefore, that line passes through the shared point (0, 1).

prove that triangles abc and def are congruent
Answer:
Below.
Step-by-step explanation:
In Δ ABC m < B = 180 - (50+70) = 60 degrees.
in Δ DEF m < D = 180- ( 60 + 70) = 50 degrees.
BC = DE ( both are 10 cm).
m < A = m < F ( both 70 and directly opposite BC and DE)
m < C = m < D (corresponding angles and both = 50 degree)
Therefore, Δ's ABC and DEF are congruent by AAS.

Show work please and thank you.
Step-by-step explanation:
2 things to remember :
the sum of all angles in a triangle is ashtrays 180°.
the sum of all angles around a point on one side of a line is also always 180° (because that represents a half-circle).
let's call the 3rd angle in the triangle "innerQ".
so,
180 = (4x + 13) + 19 + innerQ
180 = (7x + 2) + innerQ
as innerQ is also the supplementary angle of 7x + 2.
because of that, we can now say
(4x + 13) + 19 + innerQ = (7x + 2) + innerQ
4x + 13 + 19 = 7x + 2
4x + 32 = 7x + 2
30 = 3x
x = 10
so, the angle S = 4×10 + 13 = 40 + 13 = 53°
17. Callie's cat lost 41/2 pounds before having
surgery. Two weeks after having surgery, her
cat gained 2 7/8 pounds. What was the total
change in weight of Callie's cat?
The total change in the weight of Callie's cat will be - 1 5/8 pounds.
Callie's cat lost weight = 4 1/2 pounds
Lost = 9 / 2 pounds
Cat gained the weight = 2 7/8 pounds
Gained = 23 / 8 pounds
Net change = - 9 / 2 pounds + 23 / 8 pounds
= - 36 / 8 pounds + 23 / 8 pounds
= - 13 / 8 pounds
= - 1 5/8 pounds
She lost the net weight of 1 5/8 pounds.
Therefore, the total change in the weight of Callie's cat will be - 1 5/8 pounds.

In linear equation, the missing value is a 16.
According to the statement
We have to find that the value of the linear equation.
So, For this purpose, we know that the
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
It is given that:
The equation shown includes a missing value.
-2(2x - ?) + 1 = 17 - 4x
Applying the distributive property:
-4x + ? + 1 = 17 - 4x
? + 1 = 17
There aren't any values that the equation has only 1 solution or unique solutions.
For no solution the missing value are often anything except 16
? + 1 = 17
? = 17 - 1
? = 16
Thus, there aren't any values that the equation has just one solution for no solution the missing value are often anything except 16.

The value for g(f(-4)) = -4
What are the domain of the function g(f(-4))?
Given:
g(x) = 3 x+2 and f(x)= x-2 / 3
Take, f(x) = x-2 / 3
substitute x = -4 into the function f(x). Then:
f(-4) = (-4)-2/ 3
f( -4) = -6/3
f( -4) = -2
Now, the next step is to substitute f(-4) into the function g(x)
g(x) = 3 x+2
g(f( x)) = 3 x+2
g(f(-4)) = 3(-2) +2
g(f(-4) = -6+2

A four-foot tree was planted. It will grow 2.5 feet each year. The relationships between x, the number of years since the tree has been planted, and y, the projected height of the tree is a linear relationship.
Write an equation to represent this relationship.
The relation between these two variables can be represented by the linear equation:
y = 4ft + 2.5ft*x
How to write an equation that represents this relationship?We know that the original height of the tree was 4 ft, and it grows 2.5 feet each year.
Then if we define the variables:
y = height.
x = number of years.

1.6 qt/s
Step-by-step explanation:
You want the fill rate of 24 gal/min converted to quarts per second.
Units conversionTo convert units, multiply by a factor that has units you want and cancels units you don't want. The numerator value and the denominator value of the conversion factor should be equal:
4 qt = 1 gal
1 min = 60 s
Your conversion is ...
[tex]\dfrac{24\text{ gal}}{\text{min}}=\dfrac{24\text{ gal}}{\text{min}}\times\dfrac{4\text{ qt}}{1\text{ gal}}\times\dfrac{1\text{ min}}{60\text{ s}}=\dfrac{24\cdot4}{60}\,\dfrac{\text{qt}}{\text{s}}=\boxed{1.6\text{ qt/s}}[/tex]
In an inverse variation,y = 4when x = 2.Write an inverse variatione quation thats hows there relationship between x and y . Write the equation using a decimal or an integer.
When y = 4 and x = 2, the inverse variation equation is y = 8/x
What is inverse variation?Inverse variation is variation in which the relationship between two variables is an inverse one. That is, while one variable increases, the other decreases.
How to write an inverse variation equation that shows there relationship between x and y.Given that in an inverse variation, y = 4 when x = 2. Since y and x have an inverse relationship, we have that
y ∝ 1/x, this implies that
⇒ y = k/x where k = constant of proportionality
Now, given that in an inverse variation, y = 4 when x = 2. Substituting the values of y and x into the equation, we have that
y = k/x
4 = k/2
k = 4 × 2
k = 8
So, susbstituting k = 8 into the equation for y, we have
y = k/x
y = 8/x
