Answer 1

Answer:

equation: y = -5/4xslope: -5/4point: (0, 0)

Step-by-step explanation:

The slope is found using the formula ...

m = (y2 -y1)/(x2 -x1)

m = (0 -5)/(0 -(-4)) = -5/4

slope = -5/4

The second point can be used to keep it simple.

point: (0, 0)

Point-slope equation:

y -0 = -5/4(x -0)

y = -5/4x . . . . . . . simplified

3x- 25 = 11x -5 + 2x

Please show working.

Answers

[tex]3x-25 =11x -5 +2x \\\\\implies 3x -25 = 13x-5\\\\\implies 13x -3x = 5-25\\\\\implies 10x = -20\\\\\implies x = -2[/tex]

Answer: x=-2.

Step by step:

3x-25=11x-5+2x

Combine like terms!

3x-25=(11x+2x)+(-5)

3x-25=13x+(-5)

3x-25=13x-5

Subtract 13x on both sides!

-10x-25=-5.

Add 25 to both sides.

-10x=20.

Divide both sides by -10.

x=-2.

The triangle below is isosceles. Find the length of side x in simplest radical form with
a rational denominator.
x
4

Answers

Answer:

4√2

Step-by-step explanation:

as it is an isosceles 2 sides will have the same side length so 4 and 4, therefore you can use pythagoras theorem to solve for x.

do 4²+4²=32 then square root this √32 which is equal to 4√2

The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2.

What is a triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

As per the given isosceles triangle.

The angles opposite to equal sides in the isosceles triangle will be the same.

And, The two sides of the isosceles triangle will be the same.

Both perpendicular sides' length = 4

By Pythagoras theorem,

x = √(4² + 4²)

x = √32 = 4√2

Hence "The two sides in the isosceles triangle will be the same thus the value of the third unequal side x will be 4√2".

d. n = 11 ÷ 5

e. n = 10

f. 20

Step-by-step explanation:

a. 5n = 30

n=30÷5

n=6

b. 3n-1 = 11

3n= 11 + 1

n = 12 ÷3

n=4

c. 4n + 7 = 15

4n = 15 - 7

n = 8 ÷ 4

n = 2

we know,

sum of all angles on a straight line is 180°.

so according to it,

x + 2x + 3x = 180

x = 180/6 = 30

x = 30°

therefore, value of x is 30°.

There are
r red marbles and g green marbles in a bag. When one red marble is removed and one green marble added, the ratio of red to green marbles is now 2:3 .

Subsequently, 6 red marbles and 4 green marbles are added, such that the ratio of red to green marbles is now 3:4.

What is the ratio of r to g? Your ratio must be in its simplest form.

Answers

The ratio of red marbles to green marbles, [tex]r:g=5:7[/tex]

The first sentence about what happens to the bag of marbles;

"When one red marble is removed and one green marble added, the ratio of red to green marbles is now 2:3"

Leads to the fractional equation

[tex]\frac{r-1}{g+1}=\frac{2}{3}[/tex]

After rearranging, we get equation (1) [tex]3r-2g=5[/tex]

The next sentence about what happens to the bag of marbles;

"Subsequently, 6 red marbles and 4 green marbles are added, such that the ratio of red to green marbles is now 3:4"

Leads to the fractional equation

[tex]\frac{r-1+6}{g+1+4}=\frac{3}{4}\implies \frac{r+5}{g+5}=\frac{3}{4}[/tex]

Since the first change to the bag was done without replacement. After rearranging, we get equation (2) [tex]4r-3g=-5[/tex]

So we need to solve the simultaneous equations for [tex]r[/tex] and [tex]g[/tex]

[tex]3r-2g=5\\4r-3g=-5[/tex]

Which gives [tex]r=25[/tex] and [tex]g=35[/tex]

Therefore, the ratio, [tex]r:g=25:35=5:7[/tex]
