Answer:
y = 15/4x - 11/4
Step-by-step explanation:
Slope-intercept form of the line 15x - 4y = 11 is y = (15/4)y + 11/4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in slope-intercept form is y = mx + b.
∴ 15x − 4y = 11 can be written as - 4y = - 15x + 11 ⇒ y = (15/4)y + 11/4.

The variables a and b vary directly, and b=8 when a=2.
What is the direct variation equation that relates a and b?
A.
b=2a.
B.
b-4a
C
b=8a
D
b=16a
Answer: b= 4a
( This is the correct answer, which is supposed to be option b, but a negative sign was put instead of an equal sign, so you can change appropriately)
Step-by-step explanation:
Given that a and b vary directly, can be expressed as
a ∝ b
Introducing the constant of proportionality, k, we have that
a = kb
so when a= 2, b= 8 and the constant becomes
2 = k8
k = 2/8=1/ 4
a= 1/4b
Such that
b=4a

Sandra bought 4 pounds of sweet potatoes for $6.28. What is the cost per pound of the sweet potatoes?
Answer:
Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75
Answer:
$1.57
Step-by-step explanation:
What we know:
- There are 4 pounds of sweet potatoes
- 4 pounds of sweet potatoes cost $6.28
To find the cost per pound of sweet potatoes, divide $6.28 by 4.
6.28 ÷ 4
= $1.57
Therefore, the cost per pound of sweet potatoes is $1.57.

y = 6x - 24
y = -2x
=> 6x - 24 = -2x [We change the two sides of y = two equations x above]
=> 6x - 24 + 2x = 0
=> 8x = 24
=> x = 3
=> y = -2 x 3 = -6
=> The correct ans will be (3 , -6) [x is always placed before y]

Write a quadratic equation could some please help asap
Answer:
f(x) = x^2 + 3x + 2.
Step-by-step explanation:
The zeroes of the quadratic function are -1 and -2 so we can write it as:
f(x) = a(x + 1)(x + 2) where a is some constant.
Now, when x = 1, f(x) = 6 so
6 = a(1+1)(1+2)
6 = a*2*3 = 6a
a = 1.
So the function is f(x) = (x + 1)(x + 2) = x^2 + 3x + 2.

find find the slope and Y intercept of Y= 10x - 1/3
Answer:
slope: 10
y-intercept: -1/3
Step-by-step explanation:
slope-intercept form is y = mx + b where m = slope and b = y-intercept.
the equation you're given is y = 10x - 1/3, which just happens to be in slope-intercept form already and doesn't require you to solve for any unknown variables. all you have to do is identify the m (slope) value and the b (y-intercept) value! :)
let's begin by finding your equation's slope, which is represented by the variable m in slope-intercept form! keep in mind that slope-intercept form is y = mx + b.
y = 10x - 1/3
now we need to find your equation's y-intercept, which is represented by the variable b in slope-intercept form! again, keep in mind that slope-intercept form is y = mx + b.
y = 10x - 1/3
therefore, the slope is 10 and the y-intercept is -1/3. i hope this helps! have an amazing day <3

Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81
The coordinates of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
Answer:
of quadrilateral JKLM are: J: (1,-2) K: (13,4) L: (6,8) and M: (-2,4). Prove that JKLM is a trapezoid, but not an isosceles trapezoid
The required JKLM is a trapezoid, but as the two sides are equal so JKLM is an isosceles trapezoid.
What is a quadrilateral?A quadrilateral is a four-sided shape as given in the picture in question.
A quadrilateral is a trapezoid if exactly one pair of its opposite sides are parallel. To prove that JKLM is a trapezoid, we can find the slopes of its sides and check if exactly one pair of opposite sides have the same slope. The slope of a line passing through points (x₁, y₁) and (x₂, y₂) is given by (y₂ - y₁) / (x₂ - x₁).
The slope of JK is (4 - (-2)) / (13 - 1) = 6 / 12 = 1/2
The slope of KL is (8 - 4) / (6 - 13) = 4 / (-7) = -4/7
The slope of LM is (4 - (-2)) / (-2 - 6) = 6 / -8 = -3/4
The slope of MJ is (-2 - 4) / (1 - 13) = -6 / -12 = 1/2
Since JK and LM have different slopes, we can conclude that exactly one pair of opposite sides are parallel; thus, JKLM is a trapezoid.
To prove that JKLM is not an isosceles trapezoid, we need to show that none of its sides have equal length. The distance between two points (x₁, y₁) and (x₂, y₂) can be calculated using,
The distance formula = √((x₂ - x₁)² + (y₂ - y₁)²)
We can calculate the lengths of all four sides of JKLM and see if any of them are equal.
JK = √((13 - 1)² + (4 - (-2))²) = √(144 + 36) = √(180) = 6√(5)
KL = √((6 - 13)² + (8 - 4)²) = √(49 + 16) = √(65) = √65
LM = √((-2 - 6)² + (4 - (-2))²) = √(64 + 36) = √(100) = 10
MJ = √((1 - 13)² + (-2 - 4)²) = √(144 + 36) = √(180) = 6√(5)
Since two of the four sides are equal in length, JKLM is an isosceles trapezoid.

I’m a bit confused on how to solve this problem, and could use some help!
Answer:
Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!
