Answer:
The answer is below
Step-by-step explanation:
Given that:
y = 4x - 5
y = 3x - 2
This problem can be solved graphically by plotting the graphs of both lines, and the x and y coordinate of the intersection of both lines would give the solution to the problem. Also, the problem can be solved simultaneously by:
Step 1: subtract the second line equation from the first line equation to get
0 = x - 3
x = 3
step 2: Put x = 3 in equation 1 to get
y = 4(3) - 5
y = 7
Therefore the solution = (x, y) = (3, 7)

In triangle △WXY, XY ≅ WX and m∠X=38 Find m∠W
PLEASE HELP!!
Find all missing angles
Answer:
m∠2= 52° (alt. ∠s)
m∠1 +m∠2= 180° (adj. ∠s on a str. line)
m∠1 +52°= 180°
m∠1= 180° -52°
m∠1= 128°
m∠3= 47° (alt. ∠s)
m∠4 +47°= 180°
m∠4= 180° -47°
m∠4= 133°
m∠5 +52° +47°= 180° (adj. ∠s on a str. line)
m∠5 +99°= 180°
m∠5= 180° -99°
m∠5= 81°
☆ The sum of the angles of a straight line is 180°.

Which values are in the solution set of the compound inequality -8 <3x +7s 10? Select three options.
O-15
O-5
O-3
O1
Step-by-step explanation:
-8 < 3x + 7 <= 10
-15 < 3x <= 3 (subtract 7)
-5 < x <= 1 (divide by 3)
Hence the correct options are -3, 0 and 1.

If J is the centroid of cde, de=52, fc=15, he=14, find each missing measure
Answer:
[tex]DG = 26[/tex]
[tex]GE = 26[/tex]
[tex]DF = 15[/tex]
[tex]CH = 14[/tex]
[tex]CE = 28[/tex]
Step-by-step explanation:
The figure has been attached, to complement the question.
[tex]DE = 52[/tex]
[tex]FC = 15[/tex]
[tex]HE = 14[/tex]
Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:
[tex]DF = FC[/tex]
[tex]CH = HE[/tex]
[tex]DG = GE[/tex]
Solving (a): DG
If [tex]DG = GE[/tex], then
[tex]DE = DG + GE[/tex]
[tex]DE = DG + DG[/tex]
[tex]DE = 2DG[/tex]
Make DG the subject
[tex]DG = \frac{1}{2}DE[/tex]
Substitute 52 for DE
[tex]DG = \frac{1}{2} * 52[/tex]
[tex]DG = 26[/tex]
Solving (b): GE
If [tex]DG = GE[/tex], then
[tex]GE = DG[/tex]
[tex]GE = 26[/tex]
Solving (c): DF
[tex]DF = FC[/tex]
So:
[tex]DF = 15[/tex]
Solving (d): CH
[tex]CH = HE[/tex]
[tex]CH = 14[/tex]
Solving (e): CE
If [tex]CH = HE[/tex], then
[tex]CE = CH + HE[/tex]
[tex]CE = 14 + 14[/tex]
[tex]CE = 28[/tex]
what is the best decimal equivlanet to 3 9 100
Hey there!
“What is the best decimal equivalent to 3 9/100?”
3(100) + 9
3(100) = 300
300 + 9 = 309 ⬅️ solving for your numerator
100 ÷ 1 = 100 ⬅️ solving for your denominator
309 / 100 ➡️ 309 ÷ 100 = 3.09
Thus your answer is: 3.09 ☑️

A particle moves along the curve y = 5x^2 – 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1?
Decreasing one fifth unit/sec
Increasing one fifth unit/sec
Decreasing one tenth unit/sec
Increasing one tenth unit/sec
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.
A scientist uses a submarine to study ocean life she begins at C level which is at an elevation of 0 feet then she travel straight down for 90 seconds at a speed of 3.5 ft./s then she then travels directly up for 30 seconds how do you speed of 2.2 ft./s after this 120 seconds period how much time in seconds will it take for the sciences to travel back to see if level at the submarines maximum speed of 4.8 ft./s
9514 1404 393
Answer:
10.625 seconds
Step-by-step explanation:
distance = speed · time
We want the total of all distances to be zero.
(-3.5)(90) +(2.2)(120) +(4.8)t = 0
-315 +264 +4.8t = 0 . . . . . simplify
-51 +4.8t = 0 . . . . . . . . . . . simplify more
-10.625 +t = 0 . . . . . . . . . .divide by 4.8
t = 10.625 . . . . . . . . . . . . . add 10.625
It will take the scientist 10.625 seconds to reach sea level.

The city plans to extend the Wildflower Tral to make it 2 ½ times its current length in the next 5 years. How long will the Wildflower Trail be at the end of 5 years?
Answer: 5¹⁵/₁₆
Step-by-step explanation:
The Wildflower Trail is currently 2³/₈ miles long.
If the city will extend it by 2¹/₂ in 5 years, the length in five years will be;
= 2³/₈ * 2¹/₂
= 19/8 * 5/2
= 95/16
= 5¹⁵/₁₆

In right-angled ∆ ABC, ∟B=90⁰. ∆ ABC is in the first and second quadrant on the graph paper. The coordinates of the points A and C are (2,5) and (-2,3). How do you find the possible pairs of coordinates of B?
Answer:
The given coordinates of the points A and C of the right triangle ABC are (2, 5) and (-2, 3) respectively
The possible pairs of the coordinates of the point B are found as follows;
1) Draw a horizontal line from the point C to the right and a vertical line down from the point A to get the point B at (2, 3) which is the point of the perpendicular intersection of the two constructed lines above
2) Draw a vertical line from the point C upwards and a horizontal line to the left from the point A to get the point B at (-2, 5) which is the point of the perpendicular intersection of the two newly constructed lines here

Answer:
Y = 4X - 6
Step-by-step explanation:
Slope of linear equation = change in Y / change in X
As Y is changing +4 units, with change in X +1 units. [ -6 - (-2) ] / [ 1 - 0 ]
So, slope = 4
Y = A + BX
Y = A + 4X , as B = slope & A = intercept
Putting values of X & Y (0,-6)
-6 = A + 4 (0)
A = -6
Hence, Equation : Y = 4X - 6

Which of the following are polynomials?
A. x^2 + x + 1/x^2 + 1
B. 2/x^3 + x + 1/2
C. 2/3x^2 + x + 1
D. x^2/3 + 0x + 1
E. x^3 + 2x + square root of 2
Answer:
The polynomials are:
[tex]\frac{2}{3}[/tex] x² + x + 1 ⇒ C
x³ + 2x +√2 ⇒ E
Step-by-step explanation:
A polynomial: is an expression consisting of variables and coefficients, with the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
A polynomial never division by a variableA polynomial could be one term, and it could be just a constantLet us solve the question
∵ The polynomial never division by a variable
∵ Answer A and B have a division in variable ⇒ ( [tex]\frac{1}{x^{2}+1 }[/tex] , [tex]\frac{2}{x^{3}}[/tex] )
∴ Answers A and B are not polynomials
∵ The polynomial has integer exponents of variables
∵ Answer D has a fraction exponent of x ⇒ [tex]x^{\frac{2}{3}}[/tex]
∴ Answer D is not a polynomial
∵ [tex]\frac{2}{3}[/tex] x² + x + 1 has a non-negative integer exponent of x
∵ There is no division by x
∴ [tex]\frac{2}{3}[/tex] x² + x + 1 is a polynomial
∵ x³ + 2x +√2 has a non-negative integer exponent of x
∵ There is no division by x
∴ x³ + 2x +√2 is a polynomial
∴ The polynomials are [tex]\frac{2}{3}[/tex] x² + x + 1 and x³ + 2x +√2

if one leg of a right triangle is 12 and the other leg is 16, what is the length of the hypotenuse in this right triangle?
Answer:
20
Step-by-step explanation:
Since I am given two values of the triangle, I will input the equation a²+b²=c².
"c" represents the hypotenuse. First I plug in the values of the legs, 12²+16²=c². Next I simplify these values to 144+256=c², which is 400=c². Finally I take the square root from both the value and the variable: √400=√c² which is equivalent to 20=c. Therefore, the hypotenuse is 20. Hopefully this helps :)
