PLs help with this its urgent (due tomorrow)
Answer:
Step-by-step explanation:
we are given that 1 angle equals 27 and the other two are equal.
180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
What is 2x^2+9x-18 in vertex form?
Complete the square:
2x² + 9x - 18
2(x² + 9/2 x) - 18
2(x² + 9/2 x + 81/16 - 81/16) - 18
2(x² + 2 (9/4) x + (9/4)²) - 81/8 - 18
2(x + 9/4)² - 225/8
If you're not familiar with the method, the idea is to get a quadratic from the standard form
ax² + bx + c
into its vertex form
a (x - h)² + k
where (h, k) is the vertex of the parabola associated with the quadratic.
Expand the vertex form to get
a (x² - 2xh + h²) + k
ax² - 2ahx + ah² + k
For the two forms to be equivalent, we must have
-2ah = b
ah² + k = c
which means
h = -b/(2a)
k = c - ah² = c - b²/(4a)
In this case, a = 2, b = 9, and c = -18, so
h = -9/(2 • 2) = -9/4
k = 18 - 9²/(4 • 2) = -225/8

5x2 - 45=0
Quadratic formula
Answer:
x=3
Step-by-step explanation:
5x²-45=0 | +45
5x² = 45 | :5
x² = 9 | /9
x = 3
Answer:
x=3,x=-3
Step-by-step explanation:
Use the quadratic formula
where
a=5
b=0
c=-45
which means x=(0±30)/10
so you do (0+30)/10=3
and (0-30)/10=-3

The graph of a line contains point (3, 2) and has a slope of 4. What is the equation of the line?
A. x - 4y = 2
B. x - 4y = 10
C. 4x - y = 2
D. 4x - y = 10
Answer:C 4x-y=2
Step-by-step explanation:
The equation of the line that has a slope of 4 is 4x - y = 10.
Option D is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = 4.
The line contains (3, 2).
The equation of the line.
y = mx + c
m = 4
(3, 2) = (x, y)
2 = 4 x 3 + c
2 = 12 + c
c = 2 - 12
c = -10
Now,
y = 4x - 10
4x - y = 10
Thus,
The equation of the line is 4x - y = 10.
