Answers
Answer:
Step-by-step explanation:
a. Gradient of A = 7/-7 = -1.
b. For line B, m = 3/1.5 = 2 and c = y-intercept = 3.
c. The line parallel to B will have the same gradient m = 2.
It also passes through (1, -1) so we use the point-slope form of the straight line
y - y1 = m(x - x1)
Here m = 2 and (x1, y1) = (1, -1) so
y - (-1) = 2(x - 1)
y = 2x - 2 - 1
y = 2x -3.

Ana angle measure 79.8 degrees less than the measure of it’s complementary angle what is the measure of each angle
Answers
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)

What is the inverse of the function f(x) = 2x – 10?
Answers
Answer:
f^-1(x) = (x+10) / 2
Step-by-step explanation:
sooo
f(x) = 2x - 10
y = 2x - 10
x = 2y - 10
x + 10 = 2y
y = (x + 10) / 2
f^-1(x) = (x+10) / 2
Answer:
[tex]f^{-1}(x)=\frac{x+10}{2}[/tex]
Step-by-step explanation:
[tex]f(x)=2x-10\\\\y=2x-10\\\\x=2y-10\\\\x+10=2y\\\\\frac{x+10}{2}=y\\ \\f^{-1}(x)=\frac{x+10}{2}[/tex]
As the two functions are inverses of each other, they will be symmetrical about the line [tex]y=x[/tex].

what is the density of object X if the mass is 100g with a volume of 6
Answers
Answer:
4.0 g/ml
Step-by-step explanation:
[tex] Volume_X [/tex] = water displaced by X
Water displaced by object X = Final fluid level - Original fluid level
Water displaced by object X = 90 ml - 65 ml = 25 ml
[tex] Volume_{X} = 25 ml [/tex]
Density of rock:
100 grams => 25 ml
x grams => 1 ml
Cross multiply
x*25 = 1*100
25x = 100
25x/25 = 100/25
x = 4
Density of object X = 4 g per 1 ml = 4.0 g/ml

Can someone explain how to get the answer to this question please.
Answers
Answer:
m∠2 is 55°
Step-by-step explanation:
Let us revise some facts in geometry
In any triangle, the sum of the measures of its angles is 180°If two line intersected at a point, then they formed two pairs of vertically opposite angles, the vertically opposite angles are equal in measuresWe will use these facts to solve our question
∵ ∠1 is an angle of a triangle
∴ m∠1 + 40° + 85° = 180° ⇒ 1st fact
→ Add the like terms in the left side
∴ m∠1 + 125° = 180°
→ Subtract 125° from both sides
∴ m∠1 + 125° - 125° = 180° - 125°
∴ m∠1 = 55°
∵ ∠1 and ∠2 formed from the intersecting of two lines
∴ ∠1 and ∠2 are vertically opposite angles
∴ m∠1 = m∠2 ⇒ 2nd fact
∵ m∠1 = 55°
∴ m∠2 = 55°

7) Find the base of a triangle whose height is 12cm, and area is 96cm? Your answer
Answers
Answer:
16 cm
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Substitute given information into the formula:
96= ½ ×base ×12
Simplify:
96= 6 ×base
Divide both sides by 6:
base= 96 ÷6
base= 16 cm
Answer:
16 cm[tex] \\ [/tex]
Step-by-step explanation:
It is given that, the height of a triangle is 12cm, and its area is 96cm² and we have to find the base of triangle.
[tex] \\ [/tex]
To find the base of the triangle, we have to know this formula :
[tex] \\ {\longrightarrow \pmb{\frak {\qquad \frac{1}{2} \times Base \times Height = Area_{(Triangle)} \:}}} \\ \\[/tex]
Now, substituting the values in the formula :
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{2} \times Base \times 12 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad \frac{1}{ \cancel2} \times Base \times \cancel{12 } = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad {1} \times Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base \times 6 = 96 \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad Base = \frac{96}{6} \:}}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\frak {\qquad Base = 16\:}}} \\ \\[/tex]

The sum of two numbers is 100; the first number is 12 less than the second number? What equation best represents the following
Answers
Answer:
Let the first number be f.
Let the second number be s.
f = s-12
f+s = 100
Substitute the f in the first equation for the second equation.
s-12+s = 100
2s-12 =100
2s = 112
s = 56
Therefore f = 56-12 = 44
The 2 numbers are 56 and 44.

what is the measure of 6?
explain why please
please anwser this asap.
Answers
Statement Reason
1. 3x + 7 = ∠2 (Vertically opposite angles)2. ∠2 = ∠5 (Corresponging angles)3. ∠5 = ∠6 (Vertically opposite angles)⇒ ∠2 = ∠5 = ∠6 = 3x + 7
Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.
Finding the value of x:
⇒ ∠6 + 4x + 5 = 180
⇒ 3x + 7 + 4x + 5 = 180
⇒ 7x + 12 = 180
⇒ 7x = 180 - 12
⇒ 7x = 168
⇒ 7x/7 = 168/7
⇒ x = 168/7 = 24
Now, substitute the value of x into the expression "3x + 7" to find ∠6.
Finding the measure of ∠6:
⇒ ∠6 = 3x + 7
⇒ ∠6 = 3(24) + 7
⇒ ∠6 = 72 + 7
⇒ ∠6 = 79°
