-4x + 11y = 15 x=2y Solve for y and x

Mathematics
1 answer:
Stolb23 [73]3 years ago
8 0

Answer:

to find Y

-4x + 11y = 15

x - 2y = 0

.

equal= -3x + 9y= 15

since x=2y

-3(2y) + 9y = 15

-6y + 9y =15

3y = 15

y = 15/ 3

y = 5

.

to find x

using x=2y

since

y=5

,therefore

x= 2(5)

x= 10

Drag the tiles to the correct boxes to complete the pairs not all tiles will be used match each quadratic graph to its respectiv
ch4aika [34]

Answer:

Part 1) The function of the First graph is f(x)=(x-3)(x+1)

Part 2) The function of the Second graph is f(x)=-2(x-1)(x+3)

Part 3) The function of the Third graph is f(x)=0.5(x-6)(x+2)

See the attached figure

Step-by-step explanation:

we know that

The quadratic equation in factored form is equal to

f(x)=a(x-c)(x-d)

where

a is the leading coefficient

c and d are the roots or zeros of the function

Part 1) First graph

we know that

The solutions or zeros of the first graph are

x=-1 and x=3

The parabola open up, so the leading coefficient a is positive

The function is equal to

f(x)=a(x-3)(x+1)

Find the value of the coefficient a

The vertex is equal to the point (1,-4)

substitute and solve for a

-4=a(1-3)(1+1)

-4=a(-2)(2)

a=1

therefore

The function is equal to

f(x)=(x-3)(x+1)

Part 2) Second graph

we know that

The solutions or zeros of the first graph are

x=-3 and x=1

The parabola open down, so the leading coefficient a is negative

The function is equal to

f(x)=a(x-1)(x+3)

Find the value of the coefficient a

The vertex is equal to the point (-1,8)

substitute and solve for a

8=a(-1-1)(-1+3)

8=a(-2)(2)

a=-2

therefore

The function is equal to

f(x)=-2(x-1)(x+3)

Part 3) Third graph

we know that

The solutions or zeros of the first graph are

x=-2 and x=6

The parabola open up, so the leading coefficient a is positive

The function is equal to

f(x)=a(x-6)(x+2)

Find the value of the coefficient a

The vertex is equal to the point (2,-8)

substitute and solve for a

-8=a(2-6)(2+2)

-8=a(-4)(4)

a=0.5

therefore

The function is equal to

f(x)=0.5(x-6)(x+2)

Its only one math question show right steps then get brainliest and right answer ofc
valkas [14]

Step-by-step explanation:

equation.

2(m+10)=4(m−15)

(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)

2m+20=4m+−60

2m+20=4m−60

Step 2: Subtract 4m from both sides.

2m+20−4m=4m−60−4m

−2m+20=−60

Step 3: Subtract 20 from both sides.

−2m+20−20=−60−20

−2m=−80

Step 4: Divide both sides by -2.

−2m−/2=−80/−2

m=40

Two thirds of a number is 16 what is the number?
oee [108]

Answer:

x=24

Step-by-step explanation:

We can set up an equation:

2/3 * x = 16

Multiplying both sides by the reciprocal of 2/3 to isolate the variable, we get

3/2 * 2/3 * x = 16* 3/2

1*x=24

x=24
