Step-by-step explanation:
y = 3*x + 4
y = 3*x - 7
Each one of the above equations is the equation for a straight line.
The solution for such a system is the point P ( x₀ , y₀ ) which coordinates belong to both straight lines. According to this, there is only one solution for that system ( only one point of intersection). The intersection of a pair of straight lines either can occur or not depending on the slope of the lines, if they have the same slope they are parallel, then they did not touch each other ever. How can m, be identified in the straight line equation??, just by looking at the coefficient of x.
The two equations have slope 3 they are parallel then there is not a solution ( there is not a common point to both equations)
Answer:
Step-by-step explanation:
Here is a system of linear equations: y = 3x + 4 y = 3x - 7
On October 1, Gary’s bank balance was $130. During October, he made two
withdrawals and one deposit. At the end of the month, his bank balance was
$95. List two withdrawals and one deposit that would give this final balance.
Answer:
The first withdraw could be $30 the second could be $45 and the deposit could be $40
Step-by-step explanation:
130-30=100 100-45=55 95-55=40
130-30-45+40=95
The lengths of two sides of a triangle are given below. Write an inequality to represent the range of the lengths of the 3rd side.
4 and 10
9514 1404 393
Answer:
6 < x < 14
Step-by-step explanation:
The shortest the third side can be is the difference between the given sides:
10 -4 = 6
The longest the third side can be is the sum of the given sides:
10 +4 = 14
So the inequality for side length x is ...
6 < x < 14
__
More detail
These come from the triangle inequality, which requires ...
a + b > c; b + c > a; c + a > b
Filling in 4, 10, and x, these become ...
4 + 10 > x ⇒ 14 > x . . . from the sum of the two given sides10 + x > 4 ⇒ x > -6 . . . . . less restrictive than the nextx + 4 > 10 ⇒ x > 6 . . . from the difference of the two given sidesIn summary, 6 < x < 14.

Answer:
Its 6.71
Step-by-step explanation:
Because using the formula, a^2+b^2=c2.
so it’s 3^2+6^2=6.71!

Use the original price and the markdown to find the retail price.
Original price: $120; Markdown: 26%
Answer: $88.80
Step-by-step explanation:
26% = .26
120 * .26 = 31.2
120 - 31.2 = 88.8

The weight of Ms. Winters' car is 3,807 pounds. What is another way to express this weight? (1 T = 2,000 lb)
Answer:
Weight of Ms. Winter's car is 1.9035 tons
Step-by-step explanation:
Total weight of Ms. Winter's car = 3807 pounds
It has been given in the question that 2000 pounds = 1 ton
So we will use this conversion factor to express the weight in tons.
By using unitary method,
∵ 2000 pounds = 1 Ton
∴ 1 pound = [tex]\frac{1}{2000}[/tex] Ton
∴ 3807 pounds = [tex]\frac{3807}{2000}[/tex]
= 1.9035 Tons
Therefore, weight of Ms. Winter's car is 1.9035 tons.

whats an example of a quadratic equation that cannot be factored with a real solution?
Answer:
Step-by-step explanation:
The key here is the "discriminant." That's b^2 - 4ac, where a, b and c are the coefficients of the quadratic.
If the discriminant turns out to be positive, we have two real, different roots.
If the discriminant turns out to be zero, we have two real, equal roots.
Finally, if the discriminant turns out to be negative, we have two complex, different roots.
Just supposing that a = 1 and b = 2, the discriminant would be
2^2 - 4(1)c. Set this equal to 0 and solve for c: 4 - 4c = 0, or c = 1. If c is greater than 1, the discriminant will be negative and we will have two comlex, different roots.

Help how do I solve for x and y when they are they on the same corresponding side
Answer:
y = 33.94 mm
x = 19.80 mm
Step-by-step explanation:
Because AC = CB, then ∠ABC = 45°
cos ∠ABC = 24/y
cos 45° = 0.7071 = 24/y
y = 33.94 mm
EF/BC = x/y
14/24 = x/33.94
24x = 475.16
x = 19.80 mm

Step-by-step explanation:
I believe it is 75% sorry if I'm wrong
Answer:
83%
Step-by-step explanation:
original amount:3
final amount: 0.5
percent change= amount of change/original amount
amount of change = greater value-lesser value =3-0.5=2.5
percent change=2.5/3=0.83=83%
