Answer:
a = 8
b ≠ 18
Step-by-step explanation:
y = 4x - 7
2y = ax + b
For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different
y = mx +b is the equation of a line where m is the slope and b is the y-intercept
Multiply the first equation by 2
2y = 8x - 14
2y = ax + b
So a has to equal 8
b can be anything except 14 (otherwise the lines would be the same)
9514 1404 393
Answer:
a = 8b ≠ -14Step-by-step explanation:
Multiply the first equation by 2 and you get ...
2y = 8x -14
Compare to the second equation ...
2y = ax +b
The pair of equations will have no solution if they describe parallel lines. That is, a = 8 and b ≠ -14.
__
For a ≠ 8, the lines will intersect and there will be one solution.
For a = 8 and b = -14, the lines will be coincident, and there will be infinite solutions.

Step-by-step explanation:
To multiply out brackets, you multiply the values within the bracket by the one outside one at a time.
For example, for the first one, you would do 2*a, which is 2a, then 2*3, which is 6. Since the 3 was positive, the answer would be 2a+6.

Answer:

Step-by-step explanation:
multiply 0 by 2 | 0 x 2 = 0
subtract 5 from 0 | 0 - 5 = -5
multiply 2 by 2 | 2 x 2 = 4
subtract 5 from 4 | 4 - 5 = -1
The table that represents the same linear relationship as the linear equation y = 2x - 5 is; Table A
What is the best table for the linear relationship?
The given equation is; y = 2x - 5
For the first table;
At x = 2, we have;
y = 2(2) - 5
y = -1
This and other values with input of x corresponds with the table.
For the second table;
At x = 2, we see that y = 1 instead of -1 and so this table is not correct.
For tables 3 and 4, we see that when we see that they both give the wrong values of y at x = 0 and so they are both wrong.

Answer:
let a, c represent costs for adults and children, respectively12c+3a=162; 8c+3a=122Step-by-step explanation:
You are asked only for the setup, not the solution.
I find it convenient to use variable names that remind me of what they stand for. Here, we're asked for the admission prices for adults and children, so 'a' and 'c' are convenient variables to represent those values.
Let a represent the admission price for an adult.
Let c represent the admission price for a child.
__
The first sentence gives a relation between the numbers and the total cost:
162 = 12c +3a
The second sentence gives a different relation:
122 = 8c +3a
These are the "system of equations."
_____
You aren't asked for the solution, but it is (a, c) = (14, 10). It can be found easily by subtracting the second equation from the first.
Mike pays $8,000 in property taxes, but receives a 28% tax deduction for it. What is Mike’s net expense for property taxes
Answer:
$5760
Step-by-step explanation:
Given data
Principal= $8,000
Tax= 28%
Let us compute 28% tax deduction
=28/100*8000
=0.28*8,000
=$2240
Hence the net expenses is
=8000 -2240
=$5760

In the xy-plane, the graph of which of the following equations is perpendicular to the graph of
the equation above?
•y=-3/2x-10 •y=-2/3x+10 •y=2/3x+10 •y=3/2x-10
The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.
What is the slope of any line?A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.
If two lines are perpendicular to each other then the product of their slope of them will be (-1).
⇒ m₁ ₓ m₂ = -1
The slope of line 2x + 3y = 10 will be -2/3
To be any line perpendicular whose slope m with the 2x + 3y = 10
⇒ -2/3 × m = -1
⇒ m = 3/2 so the slope of that line should be 3/2
Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

Q1x = 113° as alternate exterior angles are equalQ2Parallel lines have same slope
The given line y - 2x = 8, in slope-intercept form it is:
y = 2x + 8The slope is 2 and the first line has same slope.
Option A. y = 2x + 5Q3Supplementary angles sum to 180°°

180° - 132.6° = 47.4°ABCD is a rectangle that represents a park. The lines show all the paths in the park. The circular path is in the center of the rectangle and has a diameter of 15
Complete Question:
ABCD Is a rectangle that represents a park.
The lines show all the paths in the park.
The circular path is in the centre of the rectangle and has a diameter of 15m.
Calculate the shortest distance from A to C across the park,using only the lines shown.
*See attachment for the diagram showing the paths in the park.
Answer:
Shortest distance from A to C through the paths only = 102.9 m
Step-by-step explanation:
Length of park = 80 m
Width of park = 50 m
Diameter of the circular path in the center of the park = 15 m
Therefore:
Shortest distance between from A to C across the park if we're to follow only the lines showing the oaths would be = (length of diagonal AC - diameter of the circular path) + (½ of the circumference of the circular path)
✔️Use pythagorean theorem to find AC:
AC = √(80² + 50²) = √8,900
AC = 94.3398113 ≈ 94.34 m (nearest hundredth)
✔️Diameter of circular path = 15 m
✔️½ of the circumference of the circular path = ½(πd)
d = 15 m
½ of the circumference = ½(π*15) = 23.5619449 ≈ 23.56 m (nearest hundredth)
✔️Shortest distance = (94.34 - 15) + 23.56 = 79.34 + 23.56 = 102.9 m
