Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by
- 7x + 2y = 14?
Answers
9514 1404 393
Answer:
D y +5 = -2/7(x -4)
Step-by-step explanation:
The point-slope form is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
You're given (h, k) = (4, -5), so the equation will be of the form ...
y +5 = m(x -4) . . . . for some slope m
This form eliminates the first two choices.
__
The slope of the given line is the coefficient of x when solved for y:
2y = 7x +14
y = 7/2x +7 . . . . slope is 7/2
The perpendicular line will have a slope that is the opposite reciprocal of this, ...
-2/7 . . . . slope of perpendicular line
This is the slope shown in choice D:
y +5 = -2/7(x -4)
D
Step-by-step explanation:
Given the inequality of x < 5, select all the
possible solutions that will make this inequality true.

If an item has an original price of $65, but is discounted 20%. What is the total cost after sales tax (.0825)?
Answers
Answer:56.29$
Step-by-step explanation:
65 x .80 = 52
52 x 1.0825 = 56.29
<Brainliest is appreciated!>
Answer:
$56.29
Step-by-step explanation:
Original price = $65
discount = 20%
hence discounted price = 100% - 20% = 80% of the original price
discounted price = 80% x $65 = $52
sales tax rate = 0.0825 (i.e 8.25%)
amount of sales tax paid
= 0.0825 x discounted price
= 0.0825 x $52
= $4.29
Final cost
= discounted price + sales tax
= $52 + $4.29
= $56.29

In triangle EFG, the measure of angle E is 97 and the
measure of angle Fis 15° What is the measure of angle G?
Answers
Every triangle’s angle measures add up to 180. So you add 97 and 15 which equals 112, and then you subtract 112 from 180. 180-112= 68 so that is your final answer. I hope this helps:)
By using triangle sum theorem in triangle EFG, measure of the unknown angle ∠G will be 68°.
Calculations for the measure of angles in a triangle:
Measures of the angles in a triangle has been given as,
m∠E = 97°
m∠F = 15°
By triangle sum theorem,
m∠E + m∠F + m∠G = 180° (Sum of interior angles of a triangle is 180°)
97° + 15° + m∠G = 180°
m∠G = 180 - 112
m∠G = 68°
Therefore, measure of the third angle (∠G) of ΔEFG will be 68°.

Answer:
A: (f∘g)(x) = x
B: (g∘f)(x) = x
C: the functions are inverses
Step-by-step explanation:
A: (f∘g)(x) = f(g(x)) = f(2x +14)
= 1/2(2x +14) -7 = x +7 -7 = x
(f∘g)(x) = x
__
B: (g∘f)(x) = g(f(x)) = g(1/2x -7)
= 2(1/2x -7) +14 = x -14 +14 = x
(g∘f)(x) = x
__
C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.

Across what line of reflection was the angle reflected in the coordinate plane below?
Answers
Answer:
Let us revise the reflection
If point (x , y) reflected across the x-axis, then its image is (x , -y)
If point (x , y) reflected across the y-axis, then its image is (-x , y)
If point (x , y) reflected across the line y = x, then its image is (y , x)
If point (x , y) reflected across the line y = -x, then its image is (-y , -x)
∵ Point A (-5 , 8) is reflected across the line y = x
∵ If point (x , y) reflected across the line y = x , then its image is (y , x)
∵ x = -5 and y = 8
- Switch x and y
∴ The image of point A is A' = (8 , -5)
1. Captain Salamander has 3 pet frogs called Dorris, Borris and Morris. He weighs them to check they are the right weight. However, the frogs will only be weighed two at a time! Dorris and Borris weigh 12lbs altogether. Borris and Morris weigh 16lbs altogether. Dorris and Morris weigh 14lbs altogether. How much does each frog weigh?
Answers
Answer:
Their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
Step-by-step explanation:
Let the weights of the frogs be:
Dorris = d
Borris = b
Morris = m
given:
d + b = 12 - - - (1)
b + m = 16 - - - (2)
d + m = 14 - - - (3)
from (3)
d + m = 14
m = 14 - d - - - (4)
putting the value of m into equation 2:
b + m = 16
b + (14 - d) = 16
b - d + 14 = 16
b - d = 16 - 14
b - d = 2
b = 2 + d - - - - (5)
putting the value of 'b' in equation 5 into equation (1)
d + b = 12 - - - (1)
where: b = 2 + d - - - (5)
∴ d + (2 + d ) = 12
d + d + 2 = 12
2d = 12 - 2
2d = 10
∴ d = 10 ÷ 2 = 5
d = 5
putting the value of 'd' into eqn (5)
b = 2 + d - - - - (5)
where d = 5
b = 2 + 5 = 7
b = 7 lbs
to find 'm', let us use eqn (3)
d + m = 14 - - - (3)
where d = 5
∴ 5 + m = 14
m = 14 - 5 = 9
m = 9 lbs
Therefore their weights are:
Dorris = 5 lbs
Borris = 7 lbs
Morris = 9 lbs
