Julio tested the point (4, –2) to see whether it is a solution to this system of equations.

–3x – 2y = –8,
y = 2x – 5

His work is shown below.

Negative 3 (4) minus 2 (negative 2) = negative 8. Negative 12 + 4 = negative 8. Negative 8 = negative 8. Therefore, (4, negative 2) is a solution to the system.

Did Julio verify the solution?
No. He substituted 4 and –2 for the wrong variables.
No. He did not check the point in the second equation.
No. He simplified the equation incorrectly.
Yes. He verified that (4, –2) is a solution to the system of equations.

Write an equation of the line that passes through the given points. ​(-1,7) and (3,-5)

Answers

Answer:

y=-3x+4

Step-by-step explanation:

First, let's find the slope (m)

(-1,7), and (3,-5)

the formula is: (y2-y1)/(x2-x1)

we can label the points.

x1=-1

y1=7

x2=3

y2=-5

substitute into the equation

m=(-5-7)/(3--1)

m=(-12)/4

m=-3

Now let's use the equation for point-slope form, which is y-y1=m(x-x1)

using the labeled points from above:

y-7=-3(x+1)

do distributive prop

y-7=-3x-3

add 7 to both sides

y=-3x+4

Angel and his 2 sisters shared 1/2 cup of baby carrots. How many cups did they each get?​

Answers

Answer:

1/6 cup

Step-by-step explanation:

1/2 is to be split evenly between 3 people (Angel and his 2 sisters) so our equation is

1/2 ÷ 3 = 1/6

So, they each get 1/6 cup of baby carrots

Answer:

[tex]\frac{1}{6}[/tex] cups each.

Step-by-step explanation:

There is 1/2 of a cup of baby carrots available.

Angel and his 2 sisters would mean that there are 3 of them in all. Divide 1/2 with 3:

[tex]\frac{\frac{1}{2}}{3} = \frac{1}{2} * \frac{1}{3}[/tex]

Multiply across:

[tex]\frac{1}{2} * \frac{1}{3} = \frac{1}{6}[/tex]

Each person received [tex]\frac{1}{6}[/tex] of a cup.

An osprey flying horizontally 100 feet above a lake spots a fish below. It tilts its flight path downward by 45°. If the osprey is diving at 45 mph, at what rate is its altitude changing (rounded to the nearest foot per second)?

Answers

Answer: the rate at which its altitude is changing is -47 ft/s

Step-by-step explanation:

Given that;

ds/dt = 45 mph =  45 × 5280/3600 = 66 ft/sec

no we have to determine dx/dt

so

cos∅ = dx/dt / ds/dt

cos45° = dx/dt / 66  

dx/dt = 0.7071 × 66

dx/dt = 46.6686 ≈ 47 ft/s ( as altitude is decreasing, its negative - )

so the rate at which its altitude is changing is -47 ft/s

Given that ABC~LMN
What is the length of AC?

Answers

Answer:

B. 12

Step-by-step explanation:

✔️Find the value of x

The side lengths of two similar triangles are always proportional.

Given that ∆ABC ~ ∆LMN, therefore:

[tex] \frac{AB}{LM} = \frac{AC}{LN} [/tex]

AB = 5

LM = 10

AC = x + 5

LN = 3x + 3

Plug in the values

[tex] \frac{5}{10} = \frac{x + 5}{3x + 3} [/tex]

Cross multiply

[tex] 5(3x + 3) = 10(x + 5) [/tex]

[tex] 15x + 15 = 10x + 50 [/tex] (distributive property)

Collect like terms

[tex] 15x - 10x = -15 + 50 [/tex]

[tex] 5x = 35 [/tex]

Divide both sides by 5

x = 7

✔️Find AC

AC = x + 5

Plug in the value of x

AC = 7 + 5

AC = 12
