I think that can help :) wanna chat add me as frind
Hello there!
Before we answer the question, we must solve the equation first.
4x + 5 = 10
4x = 10 - 5
4x = 5
x = 5/4
Therefore,
The equation has one solution!
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
This is a right & isosceles triangle A =90° (Given) & AB = BC (given )
Apply Pythagoras
x² = 5(√2)² + 5(√2)² (since the 2 legs are equal)
x² = 5.2 + 5.2 Since (√2)² =2
x²=10 + 10 & x² = 20 & x=√(20) = 2√5 (the answer given are wrong.2√5 is the right answer)<u />
Answer: It might be C
Step-by-step explanation:
What vertices mean if you don't know fully:
The edges are the lines that make up the boundary of the shape. Each point where two straight edges intersect is a vertex. A triangle has three edges -- its three sides. It also has three vertices, which are each corner where two edges meet.
