Answer:
a: K = 2s
K + s = 42
b: 2s + s = 42
K = 28
s = 14
Step-by-step explanation:
1. Come up with equations based on the information given.
K = Kim
s = sister
Kim is twice of her sister -> K = 2s
When you add Kim's age to her sister's age, you get 42 -> K + s = 42
2. Substitue for K to find out the value of s
K = 2s
2s + s = 42
3. Solve for s
s = 42/3
s= 14
4. Solve for K
K = 2s
K = 2*14
K = 28
5.6+ 2.2x> 65.6- 1.8x show you work
Answer:
No
Step-by-step explanation:
cuz i dont feel like it thx for pts
The solution to the inequality 5.6 + 2.2x > 65.6 - 1.8x is x > 15.
What is the solution to the inequality?Given the inequality in the question:
5.6 + 2.2x > 65.6 - 1.8x
To solve the inequality 5.6 + 2.2x > 65.6 - 1.8, first, collect and combine the like terms on both sides of the inequality:
5.6 + 2.2x > 65.6 - 1.8x
Add 1.8x to both sides:
5.6 + 2.2x + 1.8x > 65.6 - 1.8x + 1.8x
5.6 + 2.2x + 1.8x > 65.6
5.6 + 4x > 65.6
Subtract 5.6 from both sides of the inequality:
5.6 - 5.6 + 4x > 65.6 - 5.6
4x > 60
Divide both sides by 4 to isolate the variable x:
x > 60/4
x > 15
Therefore, x is greater than 15.

Answer:D 45
Step-by-step explanation:I haven't done this in a long time but from my knowledge it is 45 because the triangle has to add up to 180 and you do 45+45 which will get you 90 leaving you with 2x and x would 45 as well and you would do 2 x 45= 90 and that is how you solve 2x.

Answer:
The answer is that angle T is 41 degrees.
Step-by-step explanation:
Line USP is a 180 angle. Knowing this, you can subtract 104 from 180.
You get 76. Then, you add 76 to 63.
The sum is 139. Then, to find the answer, you subtract 139 from 180. You know to use 180 because EVERY TRIANGLE'S ANGLES always add up to 180.
180 minus 139 is 41. This is your answer: Angle T is 41 degrees in measure.

Question 10 multiple choice
Answer: Choice B
(x-1)(x^3+x^2+5x+6)
==========================================
Explanation:
The 1 in the upper left box means that x = 1 is a root of the original polynomial.
So this means x-1 is a factor of the original polynomial.
This is because x = 1 leads to x-1 = 0 after subtracting 1 from both sides.
-----------------
The 0 in the last position of the bottom row shows we got a remainder of 0.
Getting a remainder 0 tells us that (x-1) is a factor of the polynomial. This synthetic division table confirms our initial guess.
The other values in that bottom row (1, 1, 5, 6) form coefficients to the polynomial 1x^3+1x^2+5x+6, or simply x^3+x^2+5x+6
-------------------
So we know that (x-1) and (x^3+x^2+5x+6) are factors
Meaning that,
x^4+4x^2+x-6 = (x-1)(x^3+x^2+5x+6)
You can confirm this by expanding out the right hand side (distribution rule).

What is the value of F in this equation
F^2=9/49
Answer:
[tex] \sqrt{f {}^{2} } = \sqrt{ \frac{9}{49} } [/tex]
[tex]f = \frac{ \sqrt{9} }{ \sqrt{49} } [/tex]
[tex]f = \frac{3}{7} [/tex] or -3/7
Answer:
[tex]f=-\frac{3}{7},\frac{3}{7}[/tex]
Step-by-step explanation:
[tex]f^2=\frac{9}{49}[/tex]
Square root both sides of the equation:
[tex]\sqrt{f^2} =\sqrt{\frac{9}{49} }[/tex]
The square root of [tex]f^2[/tex] is [tex]f[/tex], so let's rewrite the equation:
[tex]f=\sqrt{\frac{9}{49} }[/tex]
Now, we can make this easier on ourselves by noticing that both the numerator and denominator of the fraction are square numbers, so rewrite the equation:
[tex]f=\frac{\sqrt{9} }{\sqrt{49}}[/tex]
Find the square root of 9 (-3 & 3), and the square root of 49 (-7 & 7). Due to the possibility of the positive or negative solution, there will be two:
[tex]f=-\frac{3}{7} ,\frac{3}{7}[/tex]
Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.
function notation in slope-intercept form: f(x) = ________
reasonable domain: ≤ x ≤
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.

What are the x and y intercepts for 3x-6y=-48
Answer:
x- intercept = - 16, y- intercept = 8
Step-by-step explanation:
Given
3x - 6y = - 48
To find the x- intercept, let y = 0 in the equation and solve for x
3x - 6(0) = - 48 , that is
3x - 0 = - 48 ( divide both sides by 3 )
x = - 16 ← x- intercept or (- 16, 0 )
To find the y- intercept, let x = 0 in the equation and solve for y
3(0) - 6y = - 48 , that is
0 - 6y = - 48 ( divide both sides by - 6 )
y = 8 ← y- intercept or (0, 8 )

I need Urgent Help!! Can you please show me how you solve this step by step? 4-7x>-5(4+x)
Answer:
The answer of this inequality is: x < 12
Step-by-step explanation:
1) First, place out what is given:
[tex]4 - 7x>-5(4+x)[/tex]
2) Distribute -5 to (4 + x)
[tex]4 - 7x > -20-5x[/tex]
3) We want to get x by itself, so we need to move each term to their own side(s):
4 - 7x > - 20 - 5x
+20 + 7x > +20 +7x
---------------------------
24 > 2x
5) Divide both sides by 2
[tex]\frac{24}{2} > \frac{2x}{2}[/tex]
6) Now that you have x alone, your answer is:
[tex]x < 12[/tex]

Write an equation for the parabola that passes through (-2, 7) , (1, 10) , and (2, 27) .
Answer:y=4x^2+5x+1
Step-by-step explanation:
Just did the quiz on big ideas math
The equation of the parabola which passes through the points (-2, 7) , (1, 10) , and (2, 27) is y = (25/6)x² -(17/6)b + (1/3)c.
What is a parabola?A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.
We know equation of a parabola is y = ax² + bx + c.
Given are three points (-2, 7) , (1, 10) , and (2, 27).
If these points lie on the parabola it must verify that [tex]y_o = ax^2_o + bx_o + c.[/tex]
Therefore,
7 = a(-2)² + b(-2) + c = 0
7 = 4a - 2b + c ...(i)
10 = a(1)² + b(1) + c = 0
10 = a + b + c ...(ii)
27 = a(2)² + b(2) + c
27 = 4a + 2b + c...(iii)
Now adding eqn(i) and eqn(ii) we get 8a + 2c = 34...(iv)
Now multiplying eq(ii) by 2 and adding it to eq(i) we get 6a + 3c = 27...(v).
Now multiplying eqn(iv) by 3 and (v) by 2 and subtracting them we get a = 25/6.
Putting the value of an in eqn(iv) we get c = 1/3.
Similarly substituting the value of a and c in eqn(ii) we get b = -17/6.
∴ The equation of the parabola is y = (25/6)x² -(17/6)b + (1/3)c.
