x = 130° (exterior opposite angles)

y + x = 180° (linear pair of angles)

=> y + 130° = 180°

=> y = 180° - 130°

=> y = 50°

z = 100° (corresponding angles)

a = 100° (corresponding angles)

x + 100° = 180° (linear pair of angles)

=> x = 180° - 100°

=> x = 80°

y = x (interior opposite angles)

=> y = 80°

b = y (corresponding angles)

=> b = 80°

a = 112° (vertically opposite angles)

b = a (interior opposite angles)

=> b = 112°

x = 78° (vertically opposite angles)

x + y = 180° (interior angles on the same side of transversal)

=> 78° + y = 180°

=> y = 180° - 78°

=> y = 102°

f = 120° (vertically opposite angles)

e = 105° (vertically opposite angles)

c = 120° (corresponding angles)

d = 105° (corresponding angles)

a + d = 180° (linear pair of angles)

=> a + 105° = 180°

=> a = 180° - 105°

=> a = 75°

b + c = 180° (linear pair of angles)

=> b + 120° = 180°

=> b = 180° - 120°

=> b = 60°

Irina-Kira [14]

X = Ishaan
y = Christopher

3y = x
x = y + 14 Put the first equation into the second.
3y = y + 14
2y = 14
y = 7

Christopher is 7
Ishaan is 21

Which scenario best matches the inequality x > 3? A. Joanna needs to be in bed by 10 p.M. It's now just past 7 p.M. How many

goldfiish [28.3K]

Answer:

Step-by-step explanation:

If Ricardo started studying at 4 p.m and for sure will not stop until after 7 p.m, that means that he will be studying for 3 hours at least, and maybe even longer. So the time he will spend studying is at least 3 hours.

Therefore, x>3, where x is the time Ricardo will spend studying.

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

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