Answer: 300

Step-by-step explanation: Math - 35X10-50

I may be wrong sorry!

Replace x with 10 in the given function.

We are seeking f(10).

f(10) = 35(10) - 50

f(10) = 350 - 50

f(10) = 300

Answer:

66 cm³

Step-by-step explanation:

From the diagram,

Volume of the prism(v) = Area of the base (A)×Height(h)

v = A×h............... Equation 1

But,

A = bh/2.................... Equation 2

Where b = base of the triangle, h = height of the triangular base.

Substitute equation 2 into equation 1

v = (bh/2)H.................... Equation 3

Also for the diagram,

Given; b = 3 cm, h = 4 cm, H = 11 cm

Substitute these values into equation 3

v = (3×4×11)/2

v = 132/2

v = 66 cm³

Answer:

y= 77

Step-by-step explanation:

Write down the equation for direct proportion.

y= kx, where k is a constant.

Find the value of k.

When x= 12, y= 84,

84= k(12)

12k= 84

k= 84 ÷12

k= 7

Substitute the value of k into the equation.

y= 7x

When x=11,

y= 7(11)

y= 77

Answer:

v = 1

Step-by-step explanation:

v -10= -9

Add 10 to each side

v -10+10= -9+10

v = 1

Answer:

A) x = 15

Step-by-step explanation:

4x - 30 = 2x

subtract 2x from each side of the equation:

2x - 30 = 0

add 30 to each side:

2x = 30

x = 15

Answer:

[tex] \displaystyle A) {15}^{ \circ} [/tex]

Step-by-step explanation:

remember that,

when a transversal crosses two parallel lines then the Alternate interior angles are equal that is being said

[tex] \displaystyle 4x - 30 = 2x[/tex]

cancel 2x from both sides:

[tex] \displaystyle 2x - 30 = 0[/tex]

add 30° to both sides:

[tex] \displaystyle 2x = 30[/tex]

divide both sides by 2:

[tex] \displaystyle x =15[/tex]

hence

our answer is A)

Answer:

I'm not religious, but thank you anyways.

The upside down "T" mean perpendicular to.

Perpendicular:

per·pen·dic·u·lar

/ˌpərpənˈdikyələr/

adjective

1.

at an angle of 90° to a given line, plane, or surface.

___________________________________________________________

Since the question is asking you which one has two perpendicular lines, it can be assumed that the picture on the left is the answer, since that is the only of the two pictures that have lines what appear perpendicular.

Step-by-step explanation:

270

Suppose Moosa is ( x ) years old ,

Thus Moosa's sister is ( 3x - 6 ) years old .

The sum of their ages is 30 :

( x ) + ( 3x - 6 ) = 30 ==》 4x - 6 = 30

==》 4x = 36

==》 x = 9

So Moosa is 9 years old .

Answer:

x + y = 3  (1)

55x + 40y = 135 (2)

Step-by-step explanation:

Since  x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,

x + y = 3  (1)

Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).

Since the total distance moved is 135 miles, we have

55x + 40y = 135 (2)

So, the system of linear equations that represent the situation is

x + y = 3  (1)

55x + 40y = 135 (2)

Answer:

2x + y = -2, x + 2y = 2

4x + y - 2z = 0, 2x+ 3z = 9 , -6x - 2y + z = 0

x + y = 4 , x - y = 2

Step-by-step explanation:

Answer:

x=2 and y=−5

Step-by-step explanation:

Let's solve your system by elimination.

7x−y=19;2x−3y=19

Multiply the first equation by -3,and multiply the second equation by 1.

−3(7x−y=19)

1(2x−3y=19)

Becomes:

−21x+3y=−57

2x−3y=19

Add these equations to eliminate y:

−19x=−38

Then solve−19x=−38for x:

−19x=−38

(Divide both sides by -19)

x=2

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

7x−y=19

Substitute2forxin7x−y=19:

(7)(2)−y=19

−y+14=19(Simplify both sides of the equation)

−y+14+−14=19+−14(Add -14 to both sides)

−y=5

y=-5
