Determine whether each expression represents the statement divide the sum 15 and 6 by the difference of 10 and 3.

iris [78.8K]

Answer:

$\frac{15+6}{10-3}$

Step-by-step explanation:

Sum of 15 and 6 = 15 + 6

Difference of 10 and 3 = 10 - 3

So, the expression is

$\frac {15 + 6}{10-3}$

This is the required expression.

Can someone help me pls? I don't understand how to find x and y

coldgirl [10]

(Y+40)+(x+2y)=180
3y+x=140

2x+(y+20)=180
2x+y=160

Simultaneous equation
3y+x=140
Y+2x=160
Solve for y
Y=24
3(24)+x=140
X=140-72=68

What does h(3.2) represent?

marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

$h(t)=-16t^{2} +28t+500$

For $x=3.2\ sec$

Find the value of h(t)

$h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters$

therefore

h(3.2) represent the height of the rock $3.2$ seconds after it is propelled

see the attached figure to better understand the problem

Suppose the roots of the equation 2x^2−5x−6=0 are α and β.Find the quadratic equation with roots 1/α and 1/β.

pochemuha

Answer:

6x² + 5x - 2 = 0

Step-by-step explanation:

Given

2x² - 5x - 6 = 0 ← in standard form

with a = 2, b = - 5, c = - 6, then

sum of roots α + β = - $\frac{b}{a}$ = $\frac{5}{2}$

product of roots = $\frac{c}{a}$ = - 3, then

sum of new roots = $\frac{1}{\alpha }$ + $\frac{1}{\beta }$

= $\frac{\beta+\alpha }{\alpha \beta }$

= $\frac{\frac{5}{2} }{-3}$ = - $\frac{5}{6}$

product of new roots = $\frac{1}{\alpha }$ × $\frac{1}{\beta }$

= $\frac{1}{\alpha\beta }$ = - $\frac{1}{3}$

Hence the required equation is

x² + $\frac{5}{6}$ x - $\frac{1}{3}$ = 0 or

6x² + 5x - 2 = 0 ( multiplying through by 6 )
