1. solve equation for y: 3x - 4y = 16
2. what are the x- and y- intercepts of the line: 4x - 3y = -24
3. which ordered pair is on the graph of the equation 6x + 3y = 9
4. what is the slope of the line that passes through the points (4,8) and (1,6)
Answers
Answer:
1) y = 3/4x - 4
2) x-intercept: (-6,0) y-intercept: (0,8)
3) (-2,7)
4) slope: 2/3
Step-by-step explanation:
1) subtract 3x from both sides, divide -4 from both sides, simplify right side which gives you y = 3/4x -4
2) to get x-inter: plug in 0 for y and solve for x, the equation should look like 4x = -24, divide both sides by 4 which gives you x = -6
get y-inter: plug in 0 for x and solve for y, the equation should look like -3y=-24, divide both sides by -3 which gives you y = 8
3) plug in the points from the choices and go from there
4) slope formula: m = y2-y1/x2-x1

Answers
The total distance traveled from 0 ≤ t ≤ 7, considering the position function x(t) = t³ - 6t² - 29, is given as follows:
288.75 units.
How to obtain the total distance traveled?The position function for this problem is defined as follows:
x(t) = t³ - 6t² - 29.
The total distance traveled over an interval [a,b] is given by the definite integral of the function x(t) over the interval from x = a to x = b.
The definite integral in this problem is calculated as follows:
I = 0.25t^4 - 2t³ - 29t, from t = 0 to t = 7.
Applying the Fundamental Theorem of Calculus, the total distance is calculated as follows:
I = 0.25(7)^4 - 2(7)³ - 29(7) - (0.25(0)^4 - 2(0)³ - 29(0))
I = 288.75 units.
(which is the absolute value of the result of the definite integral).

Gross weekly income:
20(4.5 + 4.75) = $185.00Deductions:
180(12.5 + 7.65 + 6.85)/100 = $48.60Net weekly income:
185 - 48.60 = $136.403.
Saving $40, the amount left per week:

the midpoint of H J and L is the midpoint of
IJ. If KL= -3.2 + 39, and
HI = 6x + 18, what is the measure of HI?
Answers
Answer:
HI = 48 units
Step-by-step explanation:
By midpoint theorem,
"Line segment joining midpoints of two sides of a triangle measures the half of the third side of a triangle."
Since, KL is the segment joining midpoints of JH and JI,
[tex]KL = \frac{1}{2}(HI)[/tex]
-3x + 39 = [tex]\frac{1}{2}(6x + 18)[/tex]
-3x + 39 = 3x + 9
6x = 30
x = 5
Therefore, HI = 6x + 18
= 6(5) + 18
= 30 + 18
= 48

one more than 4 times a number is 14
Answers
Answer:
13 / 4 ( or ) 3.25
Step-by-step explanation:
Let the number be x.
4 times a number means,
4 ( x ) = 4x
One more than 4 times a number means,
4x + 1
One more than 4 times a number is 14,
4x + 1 = 14
4x = 14 - 1
4x = 13
x = 13 / 4
( or )
x = 3.25
Therefore, the number is 13 / 4 ( or ) 3.25

27870 x .05 = 1394
27870 + 1394 = 29264
month 2
29264 x .05 = 1463
29264 + 1463 = 30727
month 3
30727 × .05 = 1536
30727 + 1536 = 32263

if it's hard for you to multiply by 1.05, you can always divide by 20 or divide by 10 then by 2 (like the below)
1. 27870÷10= 2,787
2. 2787÷2= 1393.5
3. 27870+1393.5 = 29263.5
solution 2 -Fast but probably needs a calculator

15. Find the lengths of the sides of the kite KITE. (Answer in simplest radical form and show work)
Answers
The lengths of the sides of the kite LM is 13√2.
How does Pythagoras' rule work?According to the Pythagorean theorem, the hypotenuse of a right-angled triangle's other two sides add up to a square whose length equals the hypotenuse's.
The hypotenuse (longest side) of a right-angled triangle's square is equal to the sum of its other two sides, according to the Pythagoras theorem (base and perpendicular). Hypotenuse2 = Base2 + Perpendicular2 is how this is expressed. A2 + B2 = C2 is the formula for the hypotenuse.
According to question:-
LM = 13√2
Hypotenuse = Base 2 + Perpendicular 2.
So,
LM = √7² + 17²
LM = √49 + 289
LM = √338
LM = 13√2.

Answers
The greatest poible value of b is (72-14)/(14-(-2))×(x+2)+14.
What is possible value?Possible value is the potential for something to have a particular outcome, result, or consequence. It is the amount of beneficial or desirable result that can be achieved, given the available resources. Possible value is often determined by assessing various factors such as cost, risk, and time. It is an important concept in economics, finance, and business, as it helps to identify the most beneficial course of action.
The greatest possible value of b is found by solving the equation of the line through A and B, which is y = (72-14)/(14-(-2))×(x+2)+14.
Setting the y-value to 0 and solving for x gives x = -14, which means b = 14. Therefore, the greatest possible value of b is 14.

The Fraction for the given word problem is x/y = 9/11
What is Fraction?A fraction, which derives from the Latin word fractus, meaning "broken," is a portion of a whole or, more broadly, any number of equal parts. A fraction, such as one-half, eight-fifths, or three-quarters, indicates the number of parts of a particular size when it is used in everyday speech.
Let the fraction be x/y
The numerator of a fraction is 2 minus its denomination.
⇒ x = y - 2 .....(i)
When 3 is subtracted from numerator and from denomination the new fraction obtained is 3/4
⇒ x - 3/y - 3 = 3/4
Can also be written as
⇒ 4(x + 3) = 3(y - 3)
⇒ 4x - 12 = 3y - 9
⇒ 4x - 3y = -9 + 12
⇒ 4x - 3y = 3 .....(ii)
Substitute the value of (i) in (ii)
⇒ 4x - 3y = 3
⇒ 4(y - 2) - 3y = 3
⇒ 4y - 8 - 3y = 3
⇒ y - 8 = 3
⇒ y = 3 + 8
⇒ y = 11
Putting the value of y in (i).
⇒ x = y - 2
⇒ x = 11 - 2
⇒ x = 9
Hence, Fraction = x/y = 9/11
