−x+2y=3
A(1, 3)
B(1, 2)
C(-1, -3)
D(1, -3)
Answer:
B
Both systems can be sloved by susbituding (1,2)
Step-by-step explanation:
(1)- x−4y=−7
Substitute in the x and y values: 1 - 4 (2) = -7
Multiply the numbers : 1 - 8 = -7
Calculate the difference: -7 = -7
(2) - −x+2y=3
Substitute in the x and y values: -1 + 2 (2) = 3
Multiply the numbers : -1 + 4 = 3
Calculate the sum: 3 = 3
(5/9 multiplied by -4) + (3/4 multiplied by -6) is ? Please please help ill give brainiest!!
Answer:
- 6 13/18
Step-by-step explanation:
5/9 times -4 is -20 over 9 -20/9 -2 2/9
3/4 times -6 is -18 over 4 -18/4 -4 1/2
You need them to have a common denominator
so you can multiply the first answer by 4 and the second by 9.
You get -242/36 after a while
and then
you simplify.
You can multiply 36 six times into -242 so you get the whole number of 6 plus 216
242-216 is 26
26 over 36 is 13 over 18
-6 13/18
Find the value of x for which r || s.
Then find m<1 and m<2.
m<1 = 79- x
m<2 = 94- 2x
< means angle
Answer:
x=15
Step-by-step explanation:
79-15=64
94-30=64
The value of x for which r || s will be 15.
What are Parallel lines?
Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
Lines r and s are parallel to each other.
m ∠1 = 79 - x
m ∠2 = 94 - 2x
Since, Two lines r and s are parallel to each other.
Then, By definition of alternate angles of parallel lines;
m ∠1 = m ∠2
Now, Substitute the given values we get;
m ∠1 = m ∠2
79 - x = 94 - 2x
Subtract 79 both side,
79 - x - 79 = 94 - 2x - 79
- x = 15 - 2x
Add 2x both side,
- x + 2x = 15 - 2x + 2x
x = 15
Thus, The value of x is 15 for which r || s.

Function or not function please help I will give brainless
Answer:
It is a not a Function.
Because one number has two arrows pointing to two different numbers.
Answer:
No
Step-by-step explanation:
(the image is fuzzy so you can't really see the lines)
It seems that when x = 1, f(x) is both 4 and 5.
While two different x values can equal the same y value, one single x value cannot be equal to more than one value.
If this was a function that could be graph, there would be an extra dot at (1, 4) or (1, 5) since 1 is equal 4 or 5. This is why it is not a function.

What is the equation of this line?
Answer:
y= -5/4x + 6
Step-by-step explanation:
y= mx + b
m= -5/4 (rise over run/slope)
b= 6 (y-intercept)
-I hope this helps have a great day!
Answer:
y = -5/4(x)+6
Step-by-step explanation:
to find the equation of this line, we must first find the slope
We can write the equation of this line y = mx + b where m is the slope and b is the y-intercept
m = (y2-y1)/(x2-x1)
m = (-4-6)/(8-0)
m = -10/8
m = -5/4
b is the y intercept which is at 6
So the equation of the line is y = -5/4(x)+6
Given lines p and q are parallel, m<2 - (14x - 12), m<6 - (5y + 23), and m<8 - (8x + 27), solve for the values of x and y then solve for the measure of each angle
Answer:
x = 7.5
y = 14
m<1 = 87°
m<7 = 93°
Step-by-step explanation:
Given:
m<2 = (14x - 12),
m<6 = (5y + 23),
m<8 = (8x + 27)
m<2 + m<8 = 180° (consecutive exterior angles are supplementary)
(14x - 12) + (8x + 27) = 180 (substitution)
Solve for x
14x - 12 + 8x + 27 = 180
Collect like terms
22x + 15 = 180
Subtract 15 from each side
22x = 180 - 15
22x = 165
Divide both sides by 22
x = 7.5
m<2 = m<6 (corresponding angles are congruent)
(14x - 12) = (5y + 23) (substitution)
Plug in the value of x
14(7.5) - 12 = 5y + 23
105 - 12 = 5y + 23
93 = 5y + 23
Subtract 23 from each side
93 - 23 = 5y
70 = 5y
Divide both sides by 5
14 = y
y = 14
✅m<1 = m<8 (alternate exterior angles are congruent)
m<1 = (8x + 27) (substitution)
Plug in the value of x
m<1 = 8(7.5) + 27 = 87°
m<7 = m<2 (alternate exterior angles are congruent)
m<7 = (14x - 12) (substitution)
Plug in the value of x
m<7 = 14(7.5) - 12 = 93°
