Answer:
y= -1/2x+4
Step-by-step explanation:
slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.
Help , what is the measure of p
Answer:
Step-by-step explanation:
let angle p be x
x+27=56 degree (sum of two opposite interior angle is equal to the exterior angle formed)
x=56-27
x=29 degree
therefore p is 29 degree.

x==34,57
Answer:
Step-by-step explanation:
The roots of the quadratic equation below using the quadratic formula are option A. [-9 ± √105 ] / 6.
Given is a quadratic equation,
3x² + 9x - 2 = 0
Quadratic formula to find the roots of a general quadratic equation ax² + bx + c is,
x = [-b ± [tex]\sqrt{b^2-4ac}[/tex] ] / 2a
Here a = 3, b = 9 and c = -2.
Substituting the values,
x = [-9 ± [tex]\sqrt{9^2-(4)(3)(-2)}[/tex] ] / (2 × 3)
= [-9 ± [tex]\sqrt{81+24}[/tex] ] / 6
= [-9 ± √105 ] / 6
So the roots are [-9 ± √105 ] / 6.

Answer:
DE ≈ 16.1, ∠E ≈ 60.3°, ∠D ≈ 29.7°
Step-by-step explanation:
use pythagorean theorem:
DE² = 8² + 14² => DE = √8² + 14² ≈ 16.1
use inverse tangent function:
∠E = [tex]tan^{-1}[/tex](14/8) ≈ 60.3°
∠D = [tex]tan^{-1}[/tex](8/14) ≈ 29.7°
Answers:
side DE = 16.1 unitsangle E = 60.3 degreesangle D = 29.7 degreesThe "units" and "degrees" portions of the answers are likely to be left out.
===============================================
Explanation:
Since we have a right triangle, we can use the pythagorean theorem to find the hypotenuse DE
a^2+b^2 = c^2
c = sqrt(a^2+b^2)
c = sqrt(8^2+14^2)
c = 16.124515496597
c = 16.1 is the approximate length of side DE
----------------------------------
We'll use the tangent ratio to find angle E
tan(angle) = opposite/adjacent
tan(E) = FD/FE
tan(E) = 14/8
E = arctan(14/8)
E = 60.2551187030578
E = 60.3 degrees
The notation arctan is the same as inverse tangent. You should have a [tex]\tan^{-1}[/tex] button on your calculator to help compute the inverse tangent.
-------------------------------------
We could use the tangent ratio to solve for angle D, by noting that
tan(D) = 8/14
or we could use the idea that D+E = 90 which solves to D = 90-E
D = 90-E
D = 90-60.3
D = 29.7 degrees
Note how arctan(8/14) = 29.74488 which rounds to 29.7
What is the equation in point-slope form of the line passing through (−2, 1) and (4, 13)
Answer:
y = 2x + 5
Step-by-step explanation:
We have two points,
(-2,1) and
(4,13)
from which we can find the slope, m, where
m = (13-1)/(4--2) = 12/6 = 2
take any of the two points to form the point-slope form
y-y1 = m(x-x1)
y-13 = 2 (x-4)
y = 2x - 8 + 13 =2x+5
Check:
when x = -2, y = 2(-2)+5 = 1 checks.

Answer:
D
Step-by-step explanation:
Find the value of x and the value of y.
A. x = 6, y = 12√2
B. X = 9, y = 12
C. X= 6√3, y= 12
D. X= 6√2, y = 24
Answer:
C.
Step-by-step explanation:
x is bisecting the baseline (cutting it in 2 halves of 6).
the third angle in the main overall triangle is 60 degrees.
remember, all angles in a triangle always add up to 180 degrees.
so, 180 - 60 - 60 = 60.
that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.
=> y = 12
and now using Pythagoras to calculate the height (x) of the triangle :
y² = x² + 6² (remember, this side is only half the baseline)
12² = x² + 6²
144 = x² + 36
x² = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)

the area of a square is 4x^2+12x+9. Write an expression to represent the length of the side of the square.
Answer:
An expression to represent the length of the side of the square with an area of 4x^2+12x+9 in terms of x is 2x + 3
Step-by-step explanation:
all sides of a square are equal in length.
area of a square is the side length squared.
area a, side s, variable x.
a = 4x^2 + 12x + 9. s = ? x = ?
a = s^2.
a = 4x^2 + 12x + 9.
4x^2 + 12x + 9 = s^2.
x^2 + 3x + 9/4 = (s^2)/4.
factor x^2 + 3x + 9/4 = (s^2)/4.
(x + 3/2)(x + 3/2) = (s^2)/4.
(x + 3/2)^2 = (s^2)/4.
√((x + 3/2)^2) = √((s^2)/4).
take positive root.
x + 3/2 = s/2
solve for side s.
s/2 = x + 3/2
s = 2x + 3

Answer:
Hello! answer: 30
Step-by-step explanation:
Triangle area can be found be doing base × height × 1/2 or base × height ÷ 2
So...
12 × 5 = 60 60 ÷ 2 = 30 therefore the area is 30 hope that helps!
The area of the following right-angled triangle is 30 sq units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
By the concept of Pythagoras' theorem,
13² = 5² + h².
h² = 13² - 5².
h² = 144.
h = 12.
Now, We have the height and we can find the area of the triangle,
= (1/2)×5×12.
= 30 sq units.

Plan B: The bank gives you a 10% interest rate and compounds the interest every 6 months.
Final Account balance for Plan A: $
