Alyssa is painting 3 of the walls in her art studio blue. Each of the walls is 8.3 feet tall and 7.5 feet wide. Round the length and width to the nearest whole number (ones). Then estimate the area Alyssa will paint. Write equations to show your work.
Answer: below(=
Step-by-step explanation: Given that,
dimensions of wall = 8.3ft by 7.5ft
height of wall = 8.3
width of wall = 7.5
there are total 3 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
Height x Width
Formula to calculate area of four walls
3 (Height x Width)
= 3( 8.3ft x 7.5ft)
= 3 (62.25 ft²)
= 186.75 ft²
So area Alyssa will paint = 186.75 ft²

HELP! The Question is "Select All Ordered pairs that satisfy the function y=4x + 3.
Answer: see explanation
Step-by-step explanation: To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation
(- 1, - 1)
x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation
(2, 11)
x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation
(4, 7)
x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation
(7, 1)
x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation
Natalie and Anjali each improved their yards by planting hostas and shrubs. They bought their supplies from the same store. Natalie spent $86 on 2 hostas and 7 shrubs. Anjali spent $104 on 8 hostas and 4 shrubs. Find the cost of one hosta and the cost of one shrub
Please help it is on solving systems of equation using all methods
Answer: One hosta= $8
One shrub = $10
Step-by-step explanation:
Let the cost of one hostas be h
Let th cost of one shrub be s.
The question can be rewritten into am equation as:
2h + 7s = 86 .......... equation i
8h + 4s = 104 ........ equation ii
Multiply equation i by 8
Multiply equation ii by 2
16h + 56s = 688 ...... equation iii
16h + 8s = 208 ........ equation iv
Subtract equation iv from iii
48s = 480
s = 480/48
s = 10
One shrub cost $10
Put the value of one shrub into equation ii
8h + 4s = 104
8h + 4(10) = 104
8h + 40 = 104
8h = 104 - 40
8h = 64
h = 64/8
h = $8
One hostas cost $8

The second statement is the
of the first
A. contradiction
B. converse
C. inverse
D. contrapositive
Answer:
The second statement is the contrapositive of the first.
Step-by-step explanation:
We know that x → y is a conditional statement read as 'if x then q'.
The converse EXCHANGES the hypothesis and conclusion such as:
y → x
The 'contrapositive' statement basically NEGATES the converse of the conditional such as:
¬y → ¬x
Coming back towards the question,
Given
x ⇒ y
¬y ⇒ ¬x
Therefore, the second statement is the contrapositive of the first.
Answer:
D. Contrapositive

Answer:
See below.
Step-by-step explanation:
[tex]h(x)=-1/2(x - 4)^2 + 3[/tex]
The domain is all real numbers.
The range is all real numbers [tex]\leq 3[/tex].
The domain of the function will be all real numbers and the range of the function will be (-∞, 3].
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,
y = a(x - h)² + k
The domain means all the possible values of x and the range means all the possible values of y.
The equation of the parabola is given below.
h(x) = – 1/2(x – 4)² + 3
The vertex of the parabola is at (4, 3). The parabola is a downward parabola.
The domain of the function will be all real numbers and the range of the function will be (-∞, 3].

Identify the system of equations given in the graph below.
Hi there!
[tex]\large\boxed{\left \{ {{y=3x + 1} \atop {y = 3x - 1}} \right}[/tex]
From the graph, we can see that both lines are parallel. We can determine the slope of one line to find the slope of the other.
Use the slope formula to determine the slope of a line. In this case, I am using the blue line as a reference:
[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]
[tex]m = \frac{ 3 - 1 } { 1 - 0 } = 3[/tex]
The slope of both lines is 3.
Let's find the equation of the blue line by finding its y-intercept to solve for the "b" value in the equation y= mx + b:
y-intercept is when x = 0, or at (0, 1). Therefore:
Blue line equation: y = 3x + 1
The red line intersects the y-axis at (0, -1), therefore:
Red line equation: y = 3x - 1
The systems of equations is:
y = 3x + 1
y = 3x - 1
Answer:
y = 2x + 1
y= 2x - 1

A repairman estimates the cost of fixing a computer is at most $225.
The estimate includes $35 for a part, a $40 service charge, and $30 per hour for labor.
What is the maximum number of hours the repairman estimates for the job?
Answer:
The answer is 5 hours
Step-by-step explanation:
First u add the part and service charge toghther which is 75 and then 225 minus 75 is 150 so u divide 150 and 30 and u get 5 which is your answer.

2.7x -9 = x +7.5 need the answer can't find solution.
Answer:
x = 9.7
Step-by-step explanation:
2.7x -9 = x +7.5
2.7x - x = 7.5 + 9
1.7x = 16.5
x = 16.5/1.7
x = 9.7
Answer:
x = 9.70588
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2.7x - 9 = x + 7.5
Step 2: Solve for x
Subtract x on both sides: 1.7x - 9 = 7.5Add 9 on both sides: 1.7x = 16.5Divide 1.7 on both sides: x = 9.70588Step 3: Check
Substitute in x into the original equation to verify it's a solution.
Substitute in x: 2.7(9.70588) - 9 = 9.70588 + 7.5Multiply: 26.2059 - 9 = 9.70588 + 7.5Subtract/Add: 17.2059 = 17.2059Here we see that 17.2059 does indeed equal 17.2059.
∴ x = 9.70588 is a solution of the equation.
