Answer:
a) (0, 3.5)
b) (12, 11)
Step-by-step explanation:
The points through which the graph of the linear equation passes are;
(-4, 1) and (4, 6)
The slope of the equation of a straight line passing through points (x₁, y₁), and (x₂, y₂), 'm', is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
∴ The slope of the equation, m = (6 - 1)/(4 - (-4)) = 5/8 = 0.625
The equation of th line in point and slope form is therefore;
y - 1 = 0.625·(x - (-4))
∴ y = 0.625·(x - (-4)) + 1 = 0.625·x + 3.5
y = 0.625·x + 3.5
Therefore;
a) When x = 0, y = 0.625 × 0 + 3.5 = 3.5
∴ The point (0, 3.5) is a solution
b) When x = 12, we have, y = 0.625 × 12 + 3.5 = 11
∴ The point (12, 11) is a solution
However;
c) When x = 8, we have, y = 0.625 × 8 + 3.5 = 8.5
∴ The point (8, 5) is not a solution
d) When x = -6, we have, y = 0.625 × (-6) + 3.5 = -0.25
∴ The point (-6, 0) is not a solution
Therefore;
The points which are solutions are;
(0, 3.5) and (12, 11)
simplify 2/3(6x−1/6)+3x
Answer:
7x - 1/9
Step-by-step explanation:
2/3 (6x - 1/6) + 3x
12x/3 - 2/18 + 3x
4x - 1/9 + 3x
7x - 1/9
After simplifying, the value of expression is,
⇒ 7x - 1/9
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 2/3 (6x - 1/6) + 3x
Now, We can solve the expression as;
⇒ 2/3 (6x - 1/6) + 3x
⇒ 2/3 × 6x - 2/3 × 1/6 + 3x
⇒ 4x - 1/9 + 3x
⇒ 7x - 1/9

Answer:
A. 10 units
Step-by-step explanation:
The y-intercept of f(x) is f(0) = -9.
The y-intercept of g(x) is g(0) = g(1)/2 = 1.
The distance between these points is ...
1 -(-9) = 10 . . . units
__
We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.

Answer:
each apple is £ 1.80
Step-by-step explanation:
i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.
Then i took the remaining money and divided it by 2 to get how much each apple costs.
Answer:
1.80
Step-by-step explanation:
1) Price of Pears
[tex]1.30 * 7 = 9.10[/tex] formating: 1.30*7 = 9.10
2) Price of Apples
[tex]12.70 - 9.10 = 3.60[/tex] formating: 12.70-9.10 = 3.60
3) Price of Apples/Kg
[tex]\frac{3.60}{2} = 1.80[/tex] formating: 3.60/2 = 1.80

PLEASE HURRY!! A diver jumps off a high diving board that is 33 feet above the surface of the pool with an initial upward velocity of 6 feet per second. The height of the diver above the surface of the pool can be represented by the equation −16t2+6t+33=0
. How long will the diver be in the air, to the nearest hundredth of a second?
The diver will be in the air for approximately 0.78 seconds to the nearest hundredth of a second.
The equation that represents the height of the diver above the surface of the pool is given by:
h(t) = -16t² + 6t + 33
where t is the time in seconds and h(t) is the height of the diver above the surface of the pool in feet.
The diver will be in the air until he reaches the surface of the pool, which means that his height will be 0. Therefore, we can set h(t) equal to 0 and solve for t:
-16t² + 6t + 33 = 0
We can use the quadratic formula to solve for t:
t = (-b ± sqrt(b² - 4ac)) / 2a
where a = -16, b = 6, and c = 33.
Plugging in these values, we get:
t = (-6 ± sqrt(6² - 4(-16)(33))) / 2(-16)
t = (-6 ± sqrt(36 + 2112)) / (-32)
t = (-6 ± sqrt(2148)) / (-32)
Simplifying:
t = (-6 ± 46.34) / (-32)
So we have two solutions:
t = (-6 + 46.34) / (-32) ≈ 0.78 seconds
t = (-6 - 46.34) / (-32) ≈ 2.64 seconds
Since the diver cannot be in the air for a negative amount of time, we reject the second solution.

What is the length of the dotted line in the diagram below? Round to the nearest tenth.
Answer:
length of dotted diagonal line = 11
Step-by-step explanation:
Using the Pythagorean theorem:
length of rectangle² = 9² + 6² = 81 + 36 = 117
length of rectangle = √117 = 10.82
length of diagonal² = 2² + 10.82² = 4 + 117 = 121
