A coordinate grid is placed on top of a city map, showing the following characteristics:
• Washington Avenue is represented by the line x = 3.
.
Lincoln Avenue passes through the point (5,2).
Lincoln Avenue and Washington Avenue are parallel.
line
Lincoln Avenue is represented by the line
Answer:
Lincoln Avenue is represented by the line [tex] x = 5 [/tex], which is a VERTICAL LINE.
Step-by-step explanation:
The equation of the line of Washington Avenue, x = 3, suggests that the line is a vertical line, since a vertical line takes the form of x = k, where k is the value x would always take and also it is the x-intercept.
Given that Lincoln Avenue passes through the point (5, 2), and its line is parallel to that of Washington Avenue, it means that the line do not intercept each other, and Lincoln Avenue is also a vertical line.
Therefore, if Lincoln Avenue passes through (5, 2), its line can be represented also in the form, x = k. Where, k is the value that x would always take, and also, it is the x-intercept. x would always be 5 even when y changes.
Therefore, the equation of the line that represents Lincoln Avenue would be:
✅ [tex] x = 5 [/tex]
✅This is also a Vertical line.
USING ALGEBRA TILES Write the sum of the two algebraic expressions modeled by the algebra tiles. Let x be the variable. Then use the algebra tiles to simplify the expression. math
Answer:
the picture is super blurry can u change the picture and I'll do my best to answer it :)
Step-by-step explanation:
The sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have to determine the sum of the two algebraic expressions modeled by the algebra tiles.
Let the variable would be x.
List the algebraic expression by the algebra modeling tiles
⇒ (2x - 6) + (x +5)
⇒ 2x - 6 + x +5
Rearrange the terms and apply the arithmetic operation
⇒ 3x - 1
Therefore, the sum of the two algebraic expressions modeled by the algebra tiles is 3x - 1.

a. – 12x – 24 = -2x + 36
B. – 10x - 24 = 36
Help none of this makes sense lol.
Line B changes because you are taking -2x and adding it to both sides to get -10x -24 = 36
You do this to get the X on one side of the equation, hope this helped you :)

Let g(x) = -2(3x + 4)(x - 1)(x – 3)2 be a polynomial function.
1. Sketch a graph of the polynomial.
2. Name all horizontal and
vertical intercepts of the graph.
3. State the end behavior of g.
Answer:
Hope this helped a little :)
Step-by-step explanation:
The all horizontal and vertical intercepts of the graph are x-intercept(s): (-4/3, 0), (1,0), (3,0) and y-intercept(s): (0,72).
The given function is g(x) = -2(3x+4)(x-1)(x-3)².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) The sketch a graph of the polynomial is given below.
2) To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s):
(-4/3, 0), (1,0), (3,0)
y-intercept(s): (0,72)
3) Use the degree and the leading coefficient to determine the behavior.

A scale model drawing of a backyard is 6 centimeters wide and 8 centimeters long. The scale model uses a scale in which 2 centimeters represents 1.6 meters. What is the area of the actual backyard? 11.52 m² 22.40 m² 30.72 m² 48 m²
Answer:
First you need to divide 1.6 by 2 to get .8 then multiply
.8 x 6 = 4.8
.8 x 8 = 6.4
Then multiply 4.8 by 6.4 and get 30.72
The area of the actual backyard is 30.72 [tex]m^2[/tex]
Calculation of the area:Since A scale model drawing of a backyard is 6 centimeters wide and 8 centimeters long. The scale model uses a scale in which 2 centimeters represents 1.6 meters.
Here we were required to divide 1.6 by 2 so that 0.8 could come
Now
[tex]= (.8 \times 6) \times (.8 \times 8) \\\\= 4.8 \times 6.4[/tex]
= 30.72

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtained if she wishes the estimate to be within 0.03 with 90% confidence if (a) she uses a previous estimate of 0.34?(b) she does not use any prior estimates? n=_____(Round up to the nearest integer.)
Answer:
675 samples
752 samples
Step-by-step explanation:
Given that :
α = 90%
E = 0.03
Previous estimate (p) = 0.34
Estimated sample proportion (n)
n = p *q * (Zcritical /E)
Zcritical = α/2 = (1 - 0.9) /2 = 0.1 / 2 = 0.05
Z0.05 = 1.645 ( Z probability calculator)
q = 1 - p = 1 - 0.34 = 0.66
n = 0.34 * 0.66 * (1.645/0.03)^2
n = 674.70
n = 675
B.) without prior estimate given ;
p and q should have equal probability
Hence ;
p = 0.5 ; q = 0.5
n = 0.5 * 0.5 * (1.645/0.03)^2
n = 751.67361
n = 752

The points O, P, Q and R all lie on the same line segment, in that order, such that the
ratio of OP : PQ: QR is equal to 4:5: 2. If OR = 11, find QR.
9514 1404 393
Answer:
QR = 2
Step-by-step explanation:
The sum of ratio units is 4+5+2 = 11, corresponding to the total length OP +PQ +QR = OR. OR is also 11, so each ratio unit stands for 11/11 = 1 length unit.
The number of ratio units associated with QR is 2, so the length of QR is 2.
