Select each expression that has a value of 15 when x = 15.

Answer:

x=-8

Step-by-step explanation:

We are solving for the variable, x, so let us isolate all terms of x. Let us start by moving the numerical value 2 to the right side, thereby isolating the term 2x on the left:

2x= -18+2

2x=-16

So close! Let us divide both sides by 2 now:

x= -8

I hope this helps! Please let me know if you have any further questions :)

Answer:

-8

Step-by-step explanation:

Hey there

steps:

2x-2=-18

add 2 to both sides:

2x-2+2= -18+2

simplfy:

2x= -16

divide both sides by 3 :

[tex]\frac{2x}{2} = \frac{-16}{2}[/tex]

simplfy :

x = -8

Answer: d. 5(p + 1.5) = 12

Step-by-step explanation:

Viktor plays baseball for 1.5 hours per day. In 5 days therefore he would have played:

= 1.5 * 5 days

He also plays piano for p hours each day. In 5 days he would have played:

= 5 * p days of piano

If both of these combined is 12, the expression would be:

(1.5 * 5) + (5 * p) = 12

Factoring them using 5:

5 * (1.5 + p) = 12

5(1.5 + p) = 12

Answer:

[tex]x^{2} +y^{2} = 45[/tex]

Step-by-step explanation:

General Equation of circle is

[tex](x-x_1)^{2} +(y-y_1)^{2} = r^{2}[/tex]----------- (1)

Here

[tex](x_1, y_1)= (0, 0)[/tex]

Radius r is distance from origin (x1, y1) to point (x2, y2)=(-3, -6)

[tex]r=\sqrt{(x_2-x_1)^{2} + (y_2-y_1)^{2} }[/tex]

[tex]r= \sqrt{(-3-0)^{2} + (-6-0)^{2} }[/tex]

[tex]r= \sqrt{9+36}[/tex]

[tex]r=\sqrt{45}[/tex]

Substituting values in equation (1)

[tex](x-0)^{2} +(y-0)^{2} =( \sqrt{45})^{2}[/tex]

[tex]x^{2} +y^{2} = 45[/tex]

Distance cover in feet in one minute and one second are 5,016 feet and 83.6 feet

Given that;

Speed of car travelling = 57 mph

Find:

Distance cover in feet in one minute

Distance cover in feet in one second

Computation:

Speed of car travelling = 57 mph

Speed of car travelling in feet = 57 × 5280

Speed of car travelling in feet = 300,960 feet per hour

Distance cover in feet in one minute = 1 × [300,960 / 60]

Distance cover in feet in one minute = 5,016 feet

Distance cover in feet in one second = 1 × [5016 / 60]

Distance cover in feet in one second = 83.6 feet

Answer:

(13,3)

Step-by-step explanation:

The coordinates of V' after the transformation is: (13, 3)

The coordinate of V is given as:

V = (2,1)

The dilation rule is given as: D5.

So, we have:

V' = (2 * 5, 1 * 5)

Evaluate the product

V' = (10, 5)

Also, the translation rule is given as: (3,-2)

So, we have:

V' = (10 + 3, 5 -2)

Evaluate the sums

V' = (13, 3)

Hence, the coordinates of V' after the transformation is: (13, 3)

Answer:

y=4*10-1

y=39

you just need to replace the x with 10

The value of y, when x=10 is 39.

The given equation is y = 4x - 1.

We need to find the value of an equation for x=10.

Solving equations is computing the value of the unknown variable still balancing the equation on both sides. An equation is a condition on a variable such that two expressions in the variable have equal value. The value of the variable for which the equation is satisfied is said to be the solution of the equation.

Now, put x=10 in the given equation and simplify.

That is, y=4×10-1

⇒y=39

Therefore, the value of y, when x=10 is 39.

Answer:

The orange region has an area of 324m²

Step-by-step explanation:

You can calculate this by finding the area of the smaller white rectangle, and subtracting it from the larger orange rectangle.

The smaller rectangle has the dimensions 8m × 5m, giving us 40m².

The larger rectangle is 13m × 28m, giving us the area 364m²

So the orange area is equal to 364m² minus 40m², or 324m²

Answer:

324[tex]cm^{2}[/tex]

Step-by-step explanation:

The are of the shaded region is equal to the area of the big rectangle minus the area of the small rectangle. So the are of the shaded region can be found in a follwoing way

The are of the shaded region = Area of the big rectangle - Area of the small recatngle

The are of the shaded region = 13 x 28 - 5 x 8

The are of the shaded region = 364 - 40

The are of the shaded region = 324[tex]cm^{2}[/tex]
