2x-3y=3 5x+2y=17<br> how do i solve this?

Alina [70]

<span> 2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17) ...........15x+6y=51</span>........equation 2

adding equation 1 and equation 2;
19x=57
x=3

2x-3y=3
(2*3)-3y=3
6-3=3y
y=1

Help 0.06 is 10 times as much as

Ipatiy [6.2K]

Answer:

0.06 is 10 times as much as 0.006

Step-by-step explanation:

let the number be x

as per the condition 0.06 is 10 times as much as x.

Solve for x:

10 times as much as x represents as $10 \times x$

Then;

$0.06 = 10 \times x$ ......[1]

Division property of equality states that you divide the same number to both sides of an equation.

divide by 10 to both sides in equation [1];

$\frac{0.06}{10} = \frac{10x}{x}$

Simplify:

x = 0.006

Therefore, 0.06 is 10 times as much as 0.006

Find all solutions of the equation in the interval [0,2pi)

irinina [24]

Answer:

{π/4, 5π/4}

Step-by-step explanation:

Tan theta -1=0 could be rewritten as tan Ф = 1. The tangent function is 1 at Ф = π/4. As the period of the tangent function is π,

tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.

The solution set is {π/4, 5π/4}.

Select the correct inequality for the graph given

Kaylis [27]

Answer:

y<= 3x-1

Step-by-step explanation:

When it comes about inequalities, keep in mind the following

the < sign means that the regions is under whatever is to other side, and the > means that the region is above whatever is on the other side of the sign

So, we see for the graphic that there is a region below a line, this suggests us that there is a < sign implied

The other thing is that there is a convention in math, is the line is graphed using a dashed line, it meas that it is not part of the region, if the line is graphed using a solid line (a continued line) then the line is inside the region, hence there is a = sign implied.

So the answer is y<= 3x-1
