Answer:

x=4

Step-by-step explanation:

Add six to both sides

x/4=1

Multiply by 4 on both sides

x=4

Regroup.

x/4 - 6 = -5

Add 6 to both sides

x/4 = -5 + 6

Simplify

x/4 = 1

Solve for x

x = 1×4

x = 4

Collect like terms and simplify

[tex]5x-x =50+26\\\\4x = 76[/tex]

Divide both sides of the equation by 4

[tex]\frac{4x}{4} = \frac{76}{4}[/tex]

Simplify

[tex]x=19[/tex]

Answer:

21

Step-by-step explanation:

The given equation is linear with two variables that will have zero solutions.

A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.

Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.

If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

Therefore, the given equation is linear with two variables that will have zero solutions.

Answer:

15 unites

Step-by-step explanation:

Given:

perimeter = 30 units

scale factor = 0.5

30 units * 0.50 = 15 units

The perimeter of the resulting triangle is 15 units.

The perimeter of the dilated triangle will be, 15 units.

Dilation means changing the size of an object without changing its shape.

Given that, The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, we need to find the perimeter of the resulting triangle,

Since, the triangle is with respect to origin by a scale factor of 0.5,

Therefore, the perimeter of the original triangle will be reduced by 0.5 units,

The perimeter of dilated triangle = 30 x 0.5 = 15

Hence, the perimeter of the dilated triangle will be, 15 units.

Answer:

y=150x+200

Step-by-step explanation:

Given that:

Week : ____ 0___ 1 ___ 2 ____3 _____4

Balance : __200_350 _ 500 _ 650 ___800

Amount had in savings account = $200 before starting the job

x = number of weeks spent working

y = account balance

Slope intercept formula :

y = mx + c

C = intercept ; value of y when x = 0 = 200

m = slope or gradient = change in salary per month (350 - 200 = 500 - 350 = 650 - 500 = 800 - 650 = 150

Hence,

y = 150x + 200

Answer:

10

Step-by-step explanation:

When we subtract a negative number, it's basically a double negative, kind of like how we don't use those in English. We want to turn that into a positive, and double negatives are positive.

So, instead of 7-(-3), we get 7+3, or 10

Answer:

10

Step-by-step explanation:

[remember: (+)(+) is (+) itself , (+)(-) is (-) , (-)(-) is (+) ]

(+7)-(-3)

⇒ +7+3

⇒ 10

Answer:

v = 22.5 miles/hour

Step-by-step explanation:

It is given that,

The speed of Penguins is 33 ft/s.

We need to convert the speed to miles per hour.

We know that, 1 mile = 5280 feet

Speed,

[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]

So, the speed of the Penguins is 22.5 miles/hour.

Answer: 1) D    2) B, A     3) A

Step-by-step explanation:

Domain is the x-values

Range is the y-values

Graph is a function if no x-values are duplicated

1) option D

  (3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)

   ↓       ↓       ↓        ↓          ↓

Domain: x = {1, 1, 8, -4, 2}   → No duplicates so it is a function.

  (3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)

       ↓       ↓       ↓          ↓        ↓

Range: y = {7, 0, 1, -3}    7 is a duplicate so only needs to be listed once

2) Domain = option B, Range = option A

x-values are between -5 (included = bracket) and +5 (not included = parentheses)

y-values are between -5 (included = bracket) and +5 (included = bracket)

3) option A

Domain: x = {1, 4, 5, 7, 9}   → 4 matches to both 5 and 7 so is NOT a function

Range: y = {3, 5, 7, 8}

Answer:

y= -2x-2

Step-by-step explanation:

All parallel lines have the same slope. So, the line we create must have a slope of -2. If we multiply the x value by -2, we can find b through an equation.

-4 would be x in this case because it's a point we pass.

So, our equation would be

y= -2(-4)+b

y=8+b

Now, we know that y is 8+b. We can find b by plugging in y=6, because those are the coordinates of P.

6=8+b

b=-2

Now we know that b is -2. We put this into the equation for the parallel line and get:

y=-2x-2
