-5x + 4y = 3
x = 2y - 15
solve for x and y
I'm failing please send help
Answer:
Let's solve for x.
−5x + 4y = 3
Step 1: Add -4y to both sides.
−5x + 4y+ −4y =3+ −4y
−5x = −4y +3
Step 2: Divide both sides by -5.
-5x divided by 5 = -4y+3 divided by -5
x=4/5y + −3/5

A 13ft ladder is leaning against a wall when its base starts ti slide away from the wall. By the time its base is 12 feet from the wall, the base is moving at the rate of 5ft/sec. How fast is the top of the ladder sliding down the wall?
Given :
A 13ft ladder is leaning against a wall when its base starts ti slide away from the wall.
By the time its base is 12 feet from the wall, the base is moving at the rate of 5ft/sec.
To Find :
How fast is the top of the ladder sliding down the wall.
Solution :
By, Pythagoras theorem, distance of ladder from horizontal to wall is 5 feet.
Now, [tex]x^2 + y^2 = 13^2[/tex]
Differentiating both sides, we get :
[tex]2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}=0\\\\(2\times 12\times 5) + (2\times 5 \times \dfrac{dy}{dt})=0\\\\\dfrac{dy}{dt}= -12 \ feet/sec[/tex]

Solve the equation. Enter the answer in radical form, and then use a calculator to approximate the
solution to two decimal places, if necessary. Use a graphing calculator to graph the related function to
check your answer.
5x2 - 16 = 29
The solutions are x =
and x-
Answer:
solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]5x^2 - 16 = 29[/tex]
We need to solve the equation to find the value of x.
We can solve this equation using simple DMAS rule.
We are given:
[tex]5x^2 - 16 = 29[/tex]
Add 16 on both sides
[tex]5x^2 - 16+16 = 29+16\\5x^2=45[/tex]
Now, divide both sides by 5
[tex]\frac{5x^2}{5}=\frac{45}{5} \\x^2=9[/tex]
Now, we know that [tex]\sqrt{x^2}=\pm x[/tex]
Taking square root on both sides.
[tex]\sqrt{x^2}=\sqrt{9}\\x=\pm3[/tex]
So, we get values of x:
[tex]x=3, x=-3[/tex]
Therefore, solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]

Factor 72x−18xy
Find the Factor of 72x-18xy
Answer:
4x and (1-y)
Step-by-step explanation:
4x(1-y)
this is my answer
The factors of the expression are 18x and 4-y
Given the expression 72x - 18xy
Find the factor of each term:
72x = 18 * 4 * x
18xy = 18 * x * y
Since 18x is common to both terms, hence the factored form is expressed as:
72x - 18xy = 18x (4 - y)
The factors of the expression are 18x and 4-y

Analyze the diagram below and complete the instructions that follow. Find the value of x and the value of y
A. x=15, y= 10 √3
B. x=20, y= 10 √3
C. x=20 √3, y= 5 √3
D. x=15, y= 5 √3
Answer:
Use the SOH CAH TOA
Step-by-step explanation:
Angle = 60°
x = opposite o
y = adjacent a
10√ 3 = hypotenuse h
To find x we use SOH {sineø = o/h}
Sin 60° = x/10√ 3
x=10√ 3 * sin 60
X=15
You can use Pythagoras theorem or CAH{cosø = a/h}
Cos 60°= y/10√ 3
y=Cos 60° * 10√ 3
y=5√ 3

Answer:
Step-by-step explanation:
Remark
The point about the question is that the two sides are marked as equal.
Equation
3x + 5 = 5x + 1 Subtract 3x from both sides
Solution
3x - 3x + 5 = 5x - 3x + 1 Combine like terms
5 = 2x + 1 Subtract 1 from each side
5-1 = 2x +1 - 1 Combine
4 = 2x Divide by 2
4/2 = 2x/2
x = 2
3. a) The dimensions of your game cover are 20 cm x 15 cm. However, you need to have a strip of
constant width around the border for labeling purposes (game console type, etc). This width will
take up 32% of your game cover's total space. What is the width of the border? Make sure to
state any values that don't make sense.
20cm×15 cm =300
32
/100 = 0.32
9514 1404 393
Answer:
1.5 cm
Step-by-step explanation:
All areas are in cm^2. For a width w, the border will have an area equal to the product of its centerline length and its width:
border area = 2((20-w) +(15-w))·w = w(70 -4w)
This area is 32% of the total cover area, so is ...
0.32(20)(15) = 96
Equating these expressions for the area gives ...
96 = 70w -4w^2
w^2 -17.5w = -24 . . . . . divide by -4
w^2 -17.5w +8.75^2 = -24 +8.75^2 . . . . . complete the square
(w -8.75)^2 = 52.5625 . . . . simplify
w -8.75 = ±√52.5625 = ±7.25
A border width only makes sense if it is between 0 and 7.5 cm, so the appropriate value for w is ...
w = 8.75 ± 7.25 . . . . . . . . . add 8.75
w = 8.75 -7.25 = 1.50 . . . . . the solution w=16 makes no sense
The border width is 1.5 cm.
1.25 × 109 + 3.50 × 109 + 3.25 × 109 =
