A line passes through the points (4, 6) and (8, 7). What is its equation in point-slope form?
Answer:
y - 6 = 1/4(x - 4).
Step-by-step explanation:
The slope m = (7-6)/(8-4) = 1/4
y - y1 = m(x - x1)
Using the point (4, 6)
y - 6 = 1/4(x - 4) (answer)
The equation of line passes through the points (4, 6) and (8, 7) will be;
⇒ y = 1/4x + 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 6) and (8, 7).
Now,
Since, The equation of line passes through the points (4, 6) and (8, 7) .
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 6) / (8 - 4)
m = 1 / 4
m = 1/4
Thus, The equation of line with slope 1/4 is,
⇒ y - 6 = 1/4 (x - 4)
⇒ 4 (y - 6) = x - 4
⇒ 4y - 24 = x - 4
⇒ 4y = x - 4 + 24
⇒ 4y = x + 20
⇒ y = 1/4x + 5
Therefore, The equation of line passes through the points (4, 6) and
(8, 7) will be;
⇒ y = 1/4x + 5

Can you please help me I need to pass for my basketball game Tuesday please help if I don’t pass i can’t play !!
Answer:
x = 17
Step-by-step explanation:
The two given angles are supplementary angles, but also all angles on a straight light must add up to 180°:
3x + 14 + 7x - 4 = 180
Add like terms
3x + 7x + 14 - 4 = 180
10x + 10 = 180
Subtract 10 from both sides to isolate 10x:
10x + 10 - 10 = 180 - 10
10x = 170
Divide both sides by 10:
10x ÷ 10 = 170 ÷ 10
x = 17

22% of what number is 24.2
Answer:110
Step-by-step explanation:
24.2/x = 22/100
Where x is the number we are looking for
cross multiply
24.2*100 = 2420
22*x=22x
22x=2420
22x/22=2420/22
x= 110
so 24.2 is 22% of 110
Answer:
If 22% × 110 = 24.2 => Divide 24.2 by 110And see if we get as a result: 22% Note: Multiply a number by the fraction 100/100, and its value doesn't change.

What are the roots of the function f(x) = x2 + 2x – 1? a. x = ± √ _ 2 b. x = − 1 ± √ _ 2 c. x = 2 ± √ _ 2 d. x = 1 ± √ _ 2
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2

Incase you didn't get the notification on your other post.
Answer:
It's D)
C is incorrect because the constant is + 1, not - 8
A is incorrect because the f doesn't go up by 2 for every x value
B is incorrect because 2/3 * 2 would be 4/3 which is 1 1/3, which is wrong because g goes up by 2 every x.
D is correct because f goes up by 1/3, and the y-intercept is 1 (Where the line meets when the x-axis is 0) and 1/3 * 6x is 6x/3 which is 2x, then add the y-intercept to the equation, which should be 2x + 1

Janelle has a refrigerator magnet of the
painting that is 3.5 cm wide. What is the
length of the magnet?
Answer:
the length of the magnet is 5cm
Step-by-step explanation:
first convert the feet into inches: 2ft 6in=30in, 1ft 9in=21in
then convert inches into centimeters (times by 2.5): 30*2.5=75cm 21*2.5=52.5
then divide 52.5 by 3.5 to get a proportion: 52.5/3.5=15
then divide 75 by 15: 75/15=5cm
help meeeee pleaseeeeeeeeeeeee
Answer:
a) 92 m
b) 74 cm
Step-by-step explanation:
a)
2(length) + 2(width) = perimeter
2(x) + 2(73) = 330 m
2x + 146 = 330
2x = 184
x = 92 m
b)
length * width = area
85 * x = 6290 cm²
85x = 6290
x = 74 cm

Answer:
B) 2,000.
Step-by-step explanation:
As the mean is 6000 the total number of students = 5*6000
= 30,000.
If graduates are excluded we have 4*7000 = 28,000 students.
So the number at graduate level
= 30,000 - 28,000
= 2,000.

Answer:
D.
Step-by-step explanation:
An excluded value often comes from a zero in the denominator.
Set each denominator equal to zero creating an equation in x. If there is a solution to the equation, then there are excluded values. If the equation has no solution, then there are no excluded values.
A.

Answer:
x = 20
Step-by-step explanation:
these 3 angles form a straight line, which is 180°
3x + 80 + 2x = 180
5x + 80 = 180
5x = 100
x = 20
1st ∡ = 3(20) or 60°
3rd ∡ = 2(20) or 40°
Answer:
20
step by step explanation:
this angle is an angle on a straight line; which means, it is 180 degrees.. so :-
2x + 3x + 80 = 180 ( sum of the angles on a straight line is 180 ) < this is the theorum that has to be written
5x + 80 = 180n it became 5x coz u have to add the like terms
5x = 180 - 80 u have to subject the 5x
5x ÷ 5 = 100 ÷5 u need to cancel the 5... so since 5 is multiplied to X , to cancel it we need to divide it
x = 20
2x = 40 (20 × 2)
3x = 60 (20×3)

What is the zero of the function represented by this graph?
Answer:
Step-by-step explanation:
The easiest way to answer your question is to graph it. I've enclosed a graph for you. The answer to the question as it is asked is y ≥ 2.
The answer to your question (which is a much more interesting question) is that there is no 0. A zero of a function must touch or intersect the x axis.

the ratio of calamansi and pomelo trees in jacintos farm is 8:5. how many trees of each kind are there if there are 793 trees in his farm?
The number of trees calamansi have is 488 trees. The number of tree pomelo trees have in Jacintos farm is 305 trees
From the given information, we learnt that:
The ratio of the calamansi and pomelo trees in Jacintos farm = 8:5
If the total number of the ratio = 8 + 5 = 13
The proportion of the calamansi can be estimated as:
= (8/13) × 793
= 488 trees
The proportion of pomelo trees is:
= (5/13) × 793
= 305 trees
Therefore, we can conclude that the number of trees calamansi have is 488 trees and the number of tree pomelo trees have in Jacintos farm is 305 trees.
