Answer:
D. 34 - 7
Step-by-step explanation:
7 less than 34 represents a subtraction expression (based off the word "less", this would immediately cut out all other answers that do not have a minus sign. Such as A, B, E, and F.
We are only left with C and D, let's look at the phrase again :
"7 less than 34"
The phrase insinuates that the answer is 7 values less than the original number 34.
Meaning that 7 must be subtracted, leaving us with D. 34 - 7
Answer:
The answer to your question is: y = -1/2 x + 3
Step-by-step explanation:
Data
slope = m = 2
y-intercept = 3
line l is ⊥
Process
1.- Calculate the slope of line l
l = - 1/ m
l = - 1 / 2
(m)(l) = (2)(-1/2)
= -1 As m x l is "-1" the lines are perpendicular
2.- Find the line of line l
Equation y - y1 = m (x - x1)
Point (0, 3)
y - 3 = - 1/2 (x - 0) Substitution
y - 3 = -1/2 x Simplification
y = -1/2 x + 3
Answer:
see explanation
Step-by-step explanation:
Using the Cosine rule
a² = b² + c² - 2abcosA ← Rearranging for cosA gives
cosA = 
(a)
let a = 10, b = 7, c = 8 and A = α, then
cosα = 
= 
= 
, thus
α = 
( ) ≈ 83° ( to the nearest degree )
(b)
let the angle opposite side 7 be x
Using the Sine rule
= 
( cross- multiply )
10sinx = 7sin83 ( divide both sides by 10 )
sinx = 
, thus
x = 
( ) = 44°
The third angle can be found using the sum of angles in a triangle
third angle = 180° - (83 + 44)° = 180° - 127° = 53°
The 3 angles are 83°, 44°, 53°

Answer:
1123
Step-by-step explanation:
23 * 45 = 1035
1035 + 96 = 1131
1131 - 8 = 1123
