What is the slope of a line perpendicular to the line that passes through (4, -3) and
(3-1)?
PLZ ANSWER ASAPPP
Answer:
1/2
Step-by-step explanation:
The slope of the points (4,-3) and (3,-1) is -2
The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2
heres how you'd find the initial slope of the points
(4, -3)
-1 +2
(3, -1)
Slope= rise/run= 2/-1= -2

Answer:
(2,10)
Step-by-step explanation:
so we can substitute the y = 5x into y = 6x - 2
so we would have
5x = 6x - 2
subtract 6x from both sides
-x = -2
remove the negative signs since they're on both sides
x = 2
so now we can substitute x = 2 into y = 5x
so we would get
y = 5(2)
y = 10
So the point will be (2,10)
Check:
y = 6x - 2
10 = 6(2) - 2
10 = 12 - 12
10 = 10
y = 5x
10 = 5(2)
10 = 10
Answer:
(2, 10)
Step-by-step explanation:
substitute the given value of y into the equation (y=5x)
6x-2 =5x
solve for x
"add" the -2 to the other side to leave the x by itself on one side
6x=5x+2
"subtract" the 5x to the other side to combine the x's
6x-5x=2
collect like terms
x=2
so you now have your x to solve for y
substitute the x into the equation (y=5x)
y=5(2)
simple
y=10
and there you have it!!

Find the diameter and radius of a circle with the area of 29
Answer:
Diameter:6.08
Radius=D/2=6.08/2=3.04
Step-by-step explanation:
Answer:
The radius is
[tex] \sqrt{29} [/tex]
The diameter is
[tex]2 \sqrt{29} [/tex]
Step-by-step explanation:
The area of the circle is represent as
[tex] a = \pi \times r {}^{2} [/tex]
Where r is the radius and a is the area. Since pi is a irrational number, we won't focus on doing nothing with that instead we just take the sqr root of both sides to find the r or radius.
[tex] \sqrt{29} [/tex]
Which is the radius and it cant be simplified so the radius is
[tex] \sqrt{29} [/tex]
The diameter is twice longer than the radius so we
[tex]2 \times \sqrt{29} [/tex]
Which is
[tex]2 \sqrt{29} [/tex]

{(2, 2), (§, 2). C.;2), (, 2)
I need help please !
Answer:
yes
Step-by-step explanation:
because although some of the other are missing to be a function, it has to have an element of x and of y, it does not matter that some do not have it with one of y and one of x is enough
And if you are talking about relation it is also because they comply with the rules

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If one marble is chosen at random, what is the probability that it will be blue?
The probability that the marble is blue is (blank)
. (Enter only the decimal.)
Answer:
0.2
Step-by-step explanation:
6+4+3+2=total no of marble
=15
no of blue marble 3
[tex] \frac{3}{15} \\ = \frac{1}{5 } \\ = 0.2[/tex]
The probability that the marble is blue is 1/5 or 0.2.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Red marbles= 6
Green marbles = 4
Blue marble = 3
Yellow marbles= 2
Total marbles= 15
So, the probability getting blue marble
= blue marble / total marble
= 3/15
= 1/5

The diagram shows a cuboid.

20 cm
What is the surface area of the cuboid?
Answer:
1160 cm^2
Step-by-step explanation:
Surface area=2(lw)+2(hl)+2(hw)
So, surface area=2(15x20)+2(8x15)+2(8x20)
=2(300)+2(120)+2(160)
=600+240+320
surface area=1160 cm^2.
The surface area of the cuboid is 1160 cm²
What is the surface area of cuboid?
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Length of the cuboid L = 15 cm
Width of the cuboid W = 20 cm
Height of the cuboid H = 8 cm
Surface Area of the cuboid = 2 ( LH + LW + HW )
Substituting the values of L , H and W in the equation , we get
Surface Area of the cuboid = 2 ( ( 15 x 8 ) + ( 15 x 20 ) + ( 20 x 8 ) )
So ,
Total surface area of the cuboid = 2 ( 120 + 300 + 160 ) cm²
= 2 ( 580 ) cm²
= 1160 cm²
Hence , the Total surface area of the cuboid is 1160 cm²

Step-by-step explanation:
The triangle is right angled meaning that one of the angles is 90⁰.
90+30+(9x-3)=180 (Angle sum property of a triangle)
120+9x-3=180

What is the missing side ?
Answer:
[tex]x=12[/tex]
Step-by-step explanation:
Method 1: Pythagorean Theorem
We can use the Pythagorean Theorem to solve for [tex]x[/tex]. The Pythagorean Theorem states that in a right triangle, the sum of the squares of the legs' side lengths is equal to the length of the hypotenuse squared. Simply put, [tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse. In this case, we know that [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex], so we get:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]x^{2} +9^{2} =15^{2}[/tex] (Substitute [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex] into [tex]a^{2} +b^{2} =c^{2}[/tex])
[tex]x^{2} +81 =225[/tex] (Simplify exponents)
[tex]x^{2} +81-81=225-81[/tex] (Subtract [tex]81[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]x^{2} =144[/tex] (Simplify)
[tex]\sqrt{x^{2}} =\sqrt{144}[/tex] (Take the square root of both sides)
[tex]x=12,x=-12[/tex] (Simplify, remember that each positive number has two square roots: a positive one and a negative one)
In the context of the situation, we know that [tex]x=-12[/tex] is an extraneous solution because a polygon cannot have negative side lengths. Therefore, the final answer is [tex]x=12[/tex].
Method 2: Pythagorean Triples
Method 1 works, but there's an easier way to find the value of [tex]x[/tex]. If we look at the given lengths of [tex]9[/tex] and [tex]15[/tex], we can observe that this triangle is a [tex]3-4-5[/tex] right triangle enlarged by a scale factor of [tex]3[/tex], because [tex]3*3=9[/tex] and [tex]5*3=15[/tex]. The only side length that's missing is the [tex]4[/tex]. Therefore, [tex]x=4*3=12[/tex]. Hope this helps!
