Use cross multiply method or use scientific calculator to find it by shift solve method

Answer:

T= 1

I= 5

R= 40

Step-by-step explanation:

T: 28/7 = 4 so you should divide 7 by 7 to get t

I: 12/4 is 3 so you should divide 20 by 4 to get I

R: 36/9 is 4 so multiply 10 times 4 to get R

Simplifies to:

2x+8=x+3

Let's solve your equation step-by-step.

2x+8=x+3

Step 1: Subtract x from both sides.

2x+8−x=x+3−x

x+8=3

Step 2: Subtract 8 from both sides.

x+8−8=3−8

x=−5

wish i could help bro bro.

Answer/step-by-step explanation:

Well, we first need to find out what 2.3 of $540 is.

540 x 2.3 = 1,242.

Now, we need to find what the yearly interest rate is over the course of four years.

1,242 x 4 = $4,968.

Therefore, Trey will have earned $4,968 after four years.

To complete this problem, we need to add this to his original balance, or $540.

4,968 + 540 = 5,508

Therefore, Trey would make a total of $5,508 after four years.

Hope this helps! :D

Answer:

140 Presenrs

Step-by-step explanation:

If Santa delivers 420 presents in 15 hours and to get to 5 hours you need to divide 15 to 3, so what you do to one number you must do to the other, so therefore divide 420 by 3 to get 140 presents in 5 hours.

Answer:

$28

Step-by-step explanation:

Emmet will walk 1. 6 miles if he makes 4 trips to the park

From the information given, we have that;

It is important to note that proportion is the mathematical comparison of two numbers or elements

If 0. 4 miles is equivalent to 1 trip

Then x miles is equivalent to 4 trips

cross multiply

x = 0 . 4 × 4

Multiply through

x = 1. 6 miles

Thus, Emmet will walk 1. 6 miles if he makes 4 trips to the park

Answer:

y = -3, r = 25/4

Step-by-step explanation:

4r+5y = 10

-1 - 8 = 3y <--- This can be simplified to:

-9 = 3y

-3 = y

Now we plug -3 into y in the first equation

4r + 5y = 10

4r + 5(-3) = 10

4r - 15 = 10

4r = 25

r = 25/4

Answer:

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Neither

Line 2 and Line 3: Neither

Step-by-step explanation:

We will write all lines in slope intercept form i.e [tex]y=mx+b[/tex]

where m is slope.

And check

a) If two lines are parallel they have same slope [tex]m_1=m_2[/tex]

b) If two lines are perpendicular they have opposite reciprocal slopes i.e [tex]m_1=-\frac{1}{m_2}[/tex]

Equation for Line 1: [tex]y=-\frac{4}{3}x-4[/tex]

Already in slope-intercept form

Slope for Line 1 m is: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex]

Equation for Line 2: [tex]6x-8y=-6[/tex]

Converting into slope-intercept form:

[tex]6x-8y=-6\\-8y=-6x-6\\y=\frac{-6x-6}{-8}\\y=\frac{-6x}{-8}+\frac{-6}{-8} \\y=\frac{3x}{4}+\frac{3}{4}[/tex]

Slope for Line 2 m is: [tex]\mathbf{m_2=\frac{3}{4}}[/tex]

Equation for Line 3: [tex]-4y=3x+7[/tex]

Converting into slope-intercept form:

[tex]-4y=3x+7\\y=-\frac{3}{4} -\frac{7}{4}[/tex]

Slope for Line 3 m is: [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]

Now, finding answers

Line 1 and Line 2

Checking their slopes: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex], [tex]\mathbf{m_2=\frac{3}{4}}[/tex]

Both lines are perpendicular because they have opposite reciprocal slopes

Line 1 and Line 3

Checking their slopes: [tex]\mathbf{m_1=-\frac{4}{3}}[/tex], [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]

Slopes are neither same, nor opposite reciprocal, so they are neither

Line 2 and Line 3

Checking their slopes: [tex]\mathbf{m_2=\frac{3}{4}}[/tex], [tex]\mathbf{m_3=-\frac{3}{4}}[/tex]

Slopes are neither same, nor opposite reciprocal, so they are neither

The answers are:

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Neither

Line 2 and Line 3: Neither

The equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).

The equation of a circle with center (h,k) and radius r is :

r² = (x−h)² + (y−k)²

Given that a circle with a center at (-1, 5) and a point on the circle is (4, 4).

Since the circle passes through points (4, 4),

So the radius (r) of the circle is the distance between points (-1, 5) and (4, 4).

⇒ r² = (-1−4)² + (5−4)² = 25 + 1

⇒ r = √26

The center of the circle is given as (h,k) = (-1, 5)

So the equation of the circle is

⇒ r² = (x − h)² + (y − k)²

Substitute the values of r, h, and k in the above equation,

⇒ 26 = (x − (-1))² + (y −5)²

⇒ 26 = (x + 1)² + (y −5)²

⇒ 26 = x² + 2x +1 + y² - 10y + 25

⇒  x² + y²+ 2x - 10y = 0

Hence, the equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).
