Answer:

Step-by-step explanation:

x + 3y = 9 this can be rewritten to x = 9 - 3y

and substitute the equation to 2x - y = 4

it becomes

2 (9 - 3y) - y = 4

hope it helps

∫c<br> x sin y ds, C is the line segment from (0, 1) to (3, 5)

Mnenie [13.5K]

Parameterize the line segment $C$ by

$\mathbf r(t)=\langle x(t),y(t)\rangle=(1-t)\langle0,1\rangle+t\langle3,5\rangle=\langle3t,1+4t\rangle$

where $t\in[0,1]$ . Then

$\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt$
$\mathrm ds=\|\langle3,4\rangle\|\,\mathrm dt$
$\mathrm ds=5\,\mathrm dt$

So the integral is

$\displaystyle\int_Cx\sin y\,\mathrm ds=5\int_0^1x(t)\sin y(t)\,\mathrm dt$
$=\displaystyle5\int_0^13t\sin(1+4t)\,\mathrm dt$
$=\dfrac{15}{16}(\sin5-\sin-4\cos5)\approx-2.7516$

AB² = AC²+BC²

AB² = 9²+12²

AB²= 225

AB= 15

SinA = 12/15

A = Sin-¹(0.8)

M`A = 53°

M`B = 90- A = 90-53= 37°

Nora jogs 4 1/4miles on Monday. She jogs 1 1/2 fewer miles on Tuesday. Write and evaluate an addition expression to find how man

MakcuM [25]

Answer:

Equation: 4 1/4 + 1 3/4

Evaluation: 5 3/4

Step-by-step explanation:

So, Nora jobs 4 1/4 miles on Monday, which is 1 1/2 miles fewer than on Tuesday.

If this was 1.5 fewer miles, we need to add 1 1/2 and 4 1/4 to get our answer

We change the denominator on 1 1/2 to be 4. So, we multiply both sides by 2 and get 1 2/4

4 1/4 + 1 2/4 = 5 3/4
