Find the y-intercept and x-intercept of the line.
5x-3y=10
Answer:
strategy: put this equation into slope intercept form y = mx + b
then it is easier to find x and y intercepts
Step-by-step explanation:
5x-3y=10
5x-10=3y
5/3x - 10/3 = y
y = 5/3x - 10/3
when x is zero then y is - 10/3, that's the y intercept
when y is zero then x is 2, that's the x intercept

What is the interval notation for the compound inequality? x≤−4 or x≥5
(−∞, −4) or (5, ∞)
(−∞, −4] or [5, ∞)
(−4,5)
[−4,5]
Answer:
(-∞, -4] or [5, ∞)
Step-by-step explanation:
Because the solutions for x can also be equal to -4 and 5, brackets are used.
And because the solutions for x can be any number less than -4 or any number greater than 5, -∞ and ∞ are used respectively.

f(x) = x2. What is g(x)?
Answer: Choice C. g(x) = (3x)^2
To confirm this, plug in x = 1 and you'll find that:
g(x) = (3x)^2
g(1) = (3*1)^2
g(1) = (3)^2
g(1) = 3*3
g(1) = 9
Showing that (1,9) is on the red g(x) curve.
A classroom is 11 m long, 8 m wide and 5.5 m high Find the sum of the areas of the four walls.
( please show the working out pleaseee)
Answer:
209 m²
Step-by-step explanation:
The class room has a measurement of 11 m long, 8 m wide and 5.5 m high. Hence the walls of the classroom would be 4, with the following measurements.
Wall 1: 11 m by 5.5 m, Wall 2: 8 m by 5.5 m, Wall 3: 11 m by 5.5 m and Wall 4: 8 m by 5.5 m
The area of wall 1 = 11 m * 5.5 m = 60.5 m²
The area of wall 2 = 8 m * 5.5 m = 44 m²
The area of wall 3 = 11 m * 5.5 m = 60.5 m²
The area of wall 4 = 11 m * 5.5 m = 44 m²
The sum of areas of the fall wall = area of wall 1 + area of wall 2 + area of wall 3 + area of wall 4
The sum of areas of the fall wall = 60.5 + 44 + 60.5 + 44 = 209 m²

Express 27 4/3 in simplest radical form
Answer:
3⁴
Step-by-step explanation:
Expressing in the simplest radical form means simplifying a radical so that there are no more square roots, cube roots, fourth roots etc.
It further means removing radicals in the denominator of a fraction.
Given
[tex]27^{4/3}[/tex]
this can be written as
[tex](\sqrt[3]{27} )^{4}[/tex]
This is simplified as;
(3)⁴

Find the solution of the system of equations
shown on the graph.
Answer:
(0,6)
Step-by-step explanation:
When a system of equations is graphed, the point at which the lines intersect is a solution to the system. Looking at the graph, we can see that the lines intersect at (0,6). Therefore, (0,6) is a solution to the system of equations.

y = -3x - 2
6x + 2y = -4
Answer:
Infinitely many solutions

Help me on this math problem please! I’ve been stuck on it for 15 mins now
Answer:
Step-by-step explanation:
P = perimeter = 114
P =2 * length +2* width
P = 2(2x - 3) + 2(x)
114 = 4x-6 + 2x
114 = 6x -6
19 = x -1
20 = x
check it
2( 2x -3)+2x = ?
4x -6 +2x=?
6x -6 = ?
6(20)-6 =?
120-6 = 114
yep this is correct
A line is perpendicular to y = 3x - 8
and intersects the point (2,2).
What is the equation of this
perpendicular line?
Since the line is perpendicular, we know that the slope is reciprocal and negative to the other one.
So,
y = -4x + b
We want to find the y-intersect (b) so substitute the intersected points and solve for it.
2 = -4(2) + b
2 = -8 + b
2 + 8 = b
10 = b
So the complete equation would be:
y = -4x + 10

In the figure, point C is the midpoint of (A/E) Use the figure to answer the questions.
Avery says that AbC /DeC by the ASA congruence postulate. Do you agree or disagree Explain?
Suppose it is also known that point C is also the midpoint of (B/D Which postulate or theorem can be used to prove that aBC/DeC? Justify your answer.
Answer:
Disagree ΔABC ≅ ΔDEC by ASA butt by SAS
Step-by-step explanation:
point C is the midpoint of (A/E), C is also the midpoint of (B/D )
BC = CD and AC = CE
∠BCA = ∠ECD
ΔABC ≅ ΔDEC by SAS not by ASA

Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Part B: 3,12,8
Answer:
A yes, B no
Step-by-step explanation:
The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.
A Given 21, 18, 17 , then
21 + 18 = 39 > 17
21 + 17 = 38 > 18
18 + 17 = 35 > 21
Thus the triangle could exist
B Given 3, 12, 8 , then
3 + 12 = 9 > 8
3 + 8 = 11 < 12 ← fails the test
Thus the triangle does not exist
