Answer:

[tex] y - 2 = -3(x - 2) [/tex]

Step-by-step explanation:

The equation of the line in point-slope form is given by the formula, [tex] y - b = m(x - a) [/tex], where,

(a, b) = coordinates of a point on the line.

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Given that after buying 2 lattes, she has $2 left, this represents a point on the line which is (a, b) = (2, 2). That is, when x = 2 lattes, y = $2.

Let's find the slope using the point (2, 2) and any other point on the line, say at x = 1, when y = 5, that's (1, 5).

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{1 - 2} [/tex]

[tex] = \frac{3}{-1} [/tex]

[tex] m = slope = -3 [/tex]

Plug m = -3, a = 2, and b = 2 into point-slope form.

[tex] y - b = m(x - a) [/tex]

[tex] y - 2 = -3(x - 2) [/tex]

Answer:

x = 15

Step-by-step explanation:

Step 1: Define

j(x) = -4/5x + 7

j(x) = -5

Step 2: Substitute and Evaluate

-5 = -4/5x + 7

-12 = -4/5x

x = 15

Answer:

x = - 4

Step-by-step explanation:

Given f(x) = - 6x + 4 and f(x) = 28, then equating

- 6x + 4 = 28 ( subtract 4 from both sides )

- 6x = 24 ( divide both sides by - 6 )

x = - 4

Answer:

[tex]m=\frac{-1}{2}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

[tex]m=\frac{-3-(-1)}{2-(-2)}[/tex]

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

[tex]m=\frac{-2}{4}[/tex]

[tex]m=\frac{-1}{2}[/tex]

-18x×3>x

Calculate the product

-54x>x

now we do the same thing only different way ok

-18x×3

Multiply a negative and a positive equals a negative:(-)x(+)=(-)

-(18×3)x

Multiply the numbers

-54x

now we do the same thing only different way ok

-54x>x

Move variable to the left hand side and change its sign

-54x-x>0

the same way only different way ok

-54x>x

Move variable to the left by adding its opposite to both sides

-54x-x>x-x

the sum of two opposites equals 0

-54x-x>0

Collect like terms

-55x>0

the same way only different way ok

-54x-x

If a negative term doesn't have a coefficient, it is considered that the coefficient is -1

-54x-1x

Collect like terms by calculating the sum or difference of their coefficients

(-54-1)x

Calculate the difference

-55x

now we do the same thing only different way ok

-54x-y>0

Collect like terms

-55x>0

Divide both sides of the inequality by -55 and flip the inequality sign

x<0

Now we do the same thing only different way ok

-55x>0

Divide both sides of the inequality by-55 and flip the inequality sign

-55x÷(-55)<0÷(-55)

any expression Divided by itself equals 1

x<0÷(-55)

0 Divided by any non-zero expression equals 0

Answer : x<0

Answer:

13 slices

Step-by-step explanation:

The pizza has 24 slices. To figure out what 1/8 of 24 is, divide 24 by 8. To figure out what 1/3 of 24 is, divide 24 by 3. 1/8 of 24 is 3, and 1/3 of 24 is 8.

3 + 8 = 11 (number of slices eaten)

24 - 11 = 13 (number of slices left)

Answer:

20%

Step-by-step explanation:

20% of 15 is 3.

(To check 3 x 5 = 15. 20 x 5 = 1.00)

3 +15 = 18.

Answer:

20% is the answer

Step-by-step explanation:

18-15=3 inches

3/15=20%

so +20% to 15 =18 inches

Let's see. What is a right isosceles triangle?

A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.

What is the formula for the area of an isosceles triangle?

When y = the identical side lengths of the triangle,

and A = area,

(y × y) ÷ 2 = A

Note: Remember to compute from left to right! :)

We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.

Now, we can plug-in our values!

(y × y) ÷ 2 = 128

(y × y) = 64

Now, we square root both sides!

y = √64

y = 8

The length of the identical sides of the triangle is 8 meters.

[tex]\large\underline{\underline{\red{\sf \blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]

Given that area of an isosceles triangle is 128m² .

And the triangle is right Angled ∆ .

So , the measure of sides along 90° that is perpendicular and the base will be equal .

Let us say that each of the equal sides is x .

Then , we can find the area of the triangle as ,

[tex]\boxed{\bf{\red{ Area_{triangle}=\dfrac{1}{2}\times(base)\times(height)}}}[/tex]

Now , here substitute the respective values ,

[tex]\implies \sf \dfrac{1}{2}\times(base)\times(height)=128m^2[/tex]

[tex]\sf\implies \dfrac{1}{2}\times x \times x = 128m^2[/tex]

[tex]\sf \implies \dfrac{x^2}{2}=128m^2[/tex]

[tex]\sf\implies x^2=128\times2 m^2[/tex]

[tex]\sf\implies x^2=256 m^2[/tex]

[tex]\sf\implies x=\sqrt{256m^2}[/tex]

[tex]\underline{\boxed{\red{\sf\longmapsto x=16m}}}[/tex]

Hence the value of value of identical side of the triangle is 16m .

Answer:

Step-by-step explanation:

Answer:

A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)

Step-by-step explanation:

the area of a triangle is half of its base times height.

the base and the height must be perpendicular to each other; so they would be 56 and 73.

56(73)/2=2044

the perimeter is the sum of all the sides

73+56+92=221

The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.

To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.

Area of a right-angled triangle:

The area of a triangle can be found using the formula:

A = (1/2) x base x height

Plugging these values into the formula, we get:

A = (1/2) x 73 cm x 56 cm

A = 2044 cm²

Therefore, the area of the right-angled triangle is 2044 cm².

Perimeter of a right-angled triangle:

The perimeter of a triangle is the sum of all its sides.

In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.

Perimeter = 73 cm + 92 cm + 56 cm

Perimeter = 221 cm

Therefore, the perimeter of the right-angled triangle is 221 cm.
