y= -3x + 1 and y= x - 3

Answers

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

Consider an equilateral triangle that is small enough to fit in your pocket. Now consider an equilateral triangle that is big enough to fill a movie screen! What must be true about the measure of each of the interior angles for these two triangles? Does the size of a triangle influence its angle measures? What about other polygons?

Answers

Answer:

Step-by-step explanation:

First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.

Second Question: No the size does not influence the size of the interior angle.

Third Question: That's true for all polygons. Size is not affect the interior angle size.

Given : A toy car is placed on the floor. Its movement details are given

Answers

Answer:

Given :  A toy car is placed on the floor. Its movement details are given

To find : Distance covered by Car & graph to be plotted

Solution:

Start from rest

u = 0  at  t = 0

Constant acceleration for 3 sec reaching velocity 4 m/s

V = U +at

=> 4 = 0 +  a(3)

=>a = 4/3  m/s²

Distance here  S = ut + (1/2)at²

S = 0 + (1/2)(4/3)3²

=> S = 6 m

deceleration of 0.5 m/s² for 4 sec

=> v = 4  - (0.5)4

=> v = 2 m/s

Distance here   =  4(4)  - (1/2) (0.5)4²

= 16 - 4

= 12 m

Total Distance = 6 + 12 = 18 m

Total Distance traveled by toy Car = 18 m

Answers

Answer:

Step-by-step explanation:

The amount of money Mary has left in her account is $ 45

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of money in Mary's account be = $ 120

The amount of money that gets deducted for each week = $ 5

Total number of weeks elapsed = 15 weeks

So , the equation will be

Total amount deducted after 15 weeks = number of weeks elapsed x amount of money that gets deducted for each week

Total amount deducted after 15 weeks = 15 x 5

                                                                 = $ 75

Therefore , the equation will be

The amount left in Mary's account = total amount of money in Mary's account - Total amount deducted after 15 weeks

The amount left in Mary's account = 120 - 75

                                                         = $ 45

Hence , The amount of money Mary has left in her account is $ 45

A right triangle with the side AB as a length of 35 cm and another side length BC with 12 cm. What is the hypotenuse length of the right triangle?

Answers

The formula to find the hypotenuse is a^2 + b^2 = c^2. Let’s call side AB, “a” and call side BC, “b”. Now “a” = 35 cm and “b” = 12 cm. Using the formula, you square (multiply the number by itself) “a” and “b” then add them together. This would look like 35^2 + 12^2 =c^2. When you do the multiplication it ends up as 1,225 + 144 = c^2. Add 1,225 and 144 together to get 1,369 = c^2. Last step is to square root both sides to get 37 = c. So the hypotenuse of this triangle would be 37.

to the nearest tenth of a meter.

Answers

Answer:

x = 7.4

Step-by-step explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4
