Rewrite the following equation in slope-intercept form.7x − 15y = –18
Answer:
Y = 7/15x + 6/5
Step-by-step explanation:
7x - 15y = -18
7x = 15y - 18
7x + 18 = 15y
7/15x + 6/5 = y
Hope this helps! Pls give brainliest!
We can convert the line 7x − 15y = –18 into slope-intercept form (y = mx + c) by making y the subject of the equation
7x - 15y = - 18
7x + 18 = 15y
⁷/₁₅ x + ¹⁸/₁₅ = y
∴ the slope-intercept form of 7x − 15y = –18 is y = ⁷/₁₅ x + ⁶/₅

Heba ate 1/12 of a box of cereal. Now the box is 3/4 full
What fraction of a full box was there before Heba ate?
Answer:
5/6
Step-by-step explanation:
1/12 + 3/4 = 9/12
9/12 + 1/12 = 10/12

hubsdgvgcsvya
The equation that shows that the total number of markers Mrs. Larsen gets y depends on the number of boxes she buys x, will be;
⇒ y = 8x
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.
Given that;
Mrs. Larsen wants to get some markers for her class.
She notices that they come in boxes of 8.
Now,
Let total number of markers = y
And, Number of boxes = x
Here, She notices that they come in boxes of 8.
So, We can formulate;
⇒ y = 8x
Thus, The equation that shows that the total number of markers Mrs. Larsen gets y depends on the number of boxes she buys x, will be;
⇒ y = 8x

what is the equation of the line that passes through the point(-5,-4) and has a slope of -3/5?
Answer:
y= mx+c
-4= -3/5(-5) + c
-4= -3/5 *-5+ c
-4=3+c
-4-3=c
-7=c
therefore the equation of the line is y=-3/5x-7
Step-by-step explanation:
the equation of a line is
y=mx +c
where y is the y coordinate
where m is the slope
where x is the x coordinate
where c is the y- intercept

A sample of gold has a mass of 579 g. The volume of the sample is 30 cm3. What is the density of the gold sample?
The density of the gold sample is 19.3g/cm³
Let the mass of the gold sample be represented by m
m = 579 g
Let the volume of the gold sample be represented by V
V = 30 cm³
Let the density of the gold sample be represented by ρ
The formula for the density is:
[tex]Density = \frac{Mass}{Volume}[/tex]
[tex]\rho = \frac{m}{V} \\\rho = \frac{579}{30} \\\rho = 19.3 g/cm^3[/tex]
The density of the gold sample is 19.3g/cm³

[tex] \cos( \frac{3\pi}{2} + \theta) \cos(2\pi + \theta) [ \cot( \frac{3\pi}{2} - \theta) + \cot(2\pi + \theta) ] = 1 [/tex]
Please solve this problem because tomorrow is my maths exam.
Explanation:
On taking LHS
Cos[(3π/2)+θ]Cos(2π+θ)[Cot{(3π/2)-θ}+Cot(2π+θ)]
We know that
π = 180°
2π = 2×180° = 360°
3π/2 = (3×180°)/2 = 540°/2 = 270°
Now
LHS becomes
Cos(270°+θ)Cos(360°+θ)[Cot(270°-θ)+Cot(360°+θ)]
We know that
Cos (270°+θ) = Sin θ
Cos (360°+θ) = Cos θ
Cot (270°-θ) = Tan θ
Cot (360°+θ) = Cot θ
→ Sin θ Cos θ [Tan θ + Cot θ]
→ Sinθ Cosθ[(Sinθ/Cosθ)+(Cosθ/Sinθ)]
→ Sinθ Cosθ[(Sin²θ+Cos²θ)/(SinθCosθ)]
→ Sin θ Cos θ [1/(Sin θ Cos θ)]
Since Sin²θ+Cos²θ = 1
→ (Sin θ Cos θ)/(Sin θ Cos θ)
→ 1
→ RHS
→ LHS = RHS
Hence, Proved.
Here are the formulae that I have used:
→ π = 180°
→ Cos (270°+θ) = Sin θ
→ Cos (360°+θ) = Cos θ
→ Cot (270°-θ) = Tan θ
→ Cot (360°+θ) = Cot θ
Here are the Trigonometric Identities that I have used:
→ Sin²θ+Cos²θ = 1

Please answer for last question
Step-by-step explanation:
since you know already that it is a linear equation with a constant change rate (slope), you don't know the equation itself yet ?
you found the change rate (slope).
it is x goes up by 2, and y goes down by 6.
the slope is the ratio y/x representing the y and x changes, and it is always the factor of x.
"down" or "left" means "-","up" or "right" means "+".
the slope here is therefore
-6/2 = -3/1 = -3
so, we know the line function looks like
y = -3x + b
to get b we use one of the x y pairs like (1. 4)
4 = -3×1 + b
7 = b
and the full line function is
y = -3x + 7

According to the calculations made, 28 students study both subjects, and 1/2 of the class studies biology but not physics.
Given that in a class of 80 students 3/4 study biology and 3/5 study physics, to determine, if each student studies at least one of the subjects, how many students study both subjects, and find the fraction of the class that study Biology but not physics, the following calculation must be performed:
Biology: 80 x 3/4 = X 80 x 0.75 = X 60 = X Physics: 80 x 3/5 = X 80 x 0.60 = X 48 = X 60 + 48 - 80 = X 108 - 80 = X 28 = XTherefore, 28 students study both subjects.
68 - 28 = 40 80 = 1 40 = 1/2Therefore, 1/2 of the class studies biology but not physics.
