Answer:
Step-by-step explanation:
Actually Welcome to the Concept of the linear equations..
Here given value of x= 5 and y =1 , so we get as,
5a + b = 38 and 5b - a = 8
so, now we multiply equation no. 2 by 5 all over.
==> 25b - 5a = 40....(1)
hence adding new equation and equation no. 1
26b = 78
b = 78/26
hence b = 3 , and a = 7

Given that f(x) = 10x + 45, find f(-2)
Answer:
f(-2) is 25
Step-by-step explanation:
[tex]{ \tt{f(x) = 10x + 45}}[/tex]
» f(-2) means that x is -2
[tex]{ \tt{f( - 2) = 10( - 2) + 45}} \\ { \tt{f( - 2) = - 20 + 45}} \\ { \tt{f( - 2) = 25}}[/tex]

The graph of a proportional relationship contains the point (20, 4) .
What is the corresponding equation?
please hurry i need help ill give 100 points
Step-by-step explanation:
in a proportional relationship, one variable is always a constant value times the other.
and as such, (0, 0) is always a point of that relationship too.
in general that means the equation is
y = ax
with a being the constant.
using the given point :
4 = a×20
a = 4/20 = 1/5
so, the equation is y = x/5

Which inequality represents all values of x for which the quotient below is
defined?
Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because [tex]\sqrt{3(0)}[/tex]will be 0. So, the inequality can't be divided by 0.
Option C is wrong because 1 will suffice this inequality. [tex]\sqrt{7}/\sqrt{3}=1.5 (approx)[/tex]
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
The inequality x > 0 represents all values of x for which the quotient √(7x²) ÷ √(3x) is defined.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the values of x for which the quotient √(7x²) ÷ √(3x) is defined, we need to ensure that the denominator is not zero.
Since the denominator contains √(3x), we know that 3x must be positive for the expression to be defined.
So, the inequality 3x > 0 for x.
Dividing both sides by 3, we get x > 0/3, which simplifies to x > 0.
Therefore, the correct answer is (B) x > 0, which represents all values of x for which the quotient.

Answer: ( x − 4 ) ( x + 36 )
Step-by-step explanation:
Use the sum-product pattern

Given thatTriangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).
The triangle is translated as 3 units to the left and 1 unit up.
We have to determineWhat are the coordinates of B' after the translation?
According to the questionTriangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).
The triangle is translated as 3 units to the left and 1 unit up.
To find the coordinates of B', we will shift the x-coordinate of point B to left by 3 units and the y-coordinate of point B to 1 unit up.
After the given transformation the coordinates of point B' would be:
[tex]\rm B(0, \ 5) = B (0-3, \ 5+1) = B(-3, \ 6)[/tex]
Therefore, the coordinates of point B' are (-3, 6).

What is the measure of x
Answer:
[tex]\boxed{\boxed{\tt x=74^{\circ}}}[/tex]
Step-by-step explanation:
From the diagram given above, we see that ∠WXY and ∠YXZ are supplementary angles:
→ Supplementary angles are angles that add up to 180 degrees.
Therefore, [tex]\tt m\angle WXY+m\angle YXZ=180^{\circ}[/tex]

Alyssa has two part-time jobs. Her earnings for 1 wk are represented by
the equation E= 10.50c + 11.25s.
• Eis her total earnings in 1 wk.
• c is the number of hours she works as a caregiver.
• s is the number of hours she works in retail sales.
In the first week of May, Alyssa earned $195. In that week, she worked
10 h as a caregiver. For how many hours did she work in retail sales?
Answer:
it's 209 because if you multiply the same number of hours when she was a caregiver to when she was a retail salesman, she gets 209.
Use words and math to explain why these two expressions are equivalent.
3h + 2 - 6 + 5h and 2( 4h -2)
Answer:
here
Step-by-step explanation:
when given the first set, you combine like terms so you add 5h and 3h together and -6 and 2 are combined, so the first one is 8h -4. The second set you distribute 2 to 4h and -2 getting you 8h and -4 as well
Answer:
See explanation
Step-by-step explanation:
Let’s manipulate 3h+2-6+5h to show how it is equal to 2(4h-2)
Combine like-terms:
3h+2-6+5h = 8h-4
Then, factor out the greatest common factor (in this case it’s 2):
8h-4 = 2(4h-2)
If you want to verify how to above is true, just combine them again!

Which is an equation of a line parallel to the line 2x - 4y = -16?
Answer:
First we need to isolate the y in the equation
-4y=16-2x (subtract the 2x)
4y=2x-16 (divide both sides by -1)
y=1/2x-4 (divide both sides by 4)
The we know the slope of this line is 1/2. I'm not sure what the choices are, but the answer would have to have a slope of 1/2. For example, y=1/2x+2 might be an answer.

Step-by-step explanation:
In exponential growth functions the base of the exponent must be greater than 1 how would the function change if the base of the exponent were 1? How would the function change if the base of the exponent were between 0 and 1
Answer:
First, let's start with 1:
1^1 = 1
1^2 = 1
1^3 = 1
1^x = 1
It would be quite boring if we used 1
When the base is greater than 1, the function speeds up quickly and zips towards infinity. When the base is less than 1, it gets closer and closer to zero but never reaches it.
If you know what the graph looks like for an exponential graph, imagine you flip it sideways; now you have a backward "J" where the base is less than 1.
