<em>Answer:</em>

<em>In my opinion the answer is </em><em><u>y = 6</u></em>

<em>Step-by-step explanation:</em>

<em>We have two unknowns from the equation therefore, two equations are needed. These equations are: </em>

<em> </em>

<em>3x + y = 9  </em>

<em>y = –4x +10  </em>

<em> </em>

<em>To solve for y, we first substitute the second equation to the first one. </em>

<em>3x + –4x +10= 9  </em>

<em>x = 1 </em>

<em> </em>

<em>We substitute the value of x to either of the equations and solve for y. </em>

<em> </em>

<em>y = –4(1) +10  </em>

<em>y = 6</em>

Answer:

y=6

Step-by-step explanation:

3x + y = 9

y = -4x + 10

Substitute the value of y in the first equation:

3x + (-4x + 10) = 9

Apply the subtraction property of equality:

-x + 10 = 9

-x=-1

x=1

Substitute 1 for x in the given y equation

y = -4x + 10

y = -4(1)+ 10

y=6

marissa [1.9K]
To find the length of the altitude, we have to use the ratios of the similar sides.
Let the length of altitude=x
Ratio of sides:
\frac{x}{3} = \frac{27}{x}  \\&#10;Cross \ multiply \\&#10; x^{2} =81 \\&#10;Take \ square \ root.\\&#10; \sqrt{x^2}= \sqrt{81} \\&#10;x=9 \\
So length of altitude is 9 cm.

Answer: 9 cm

A quadrilateral has angles measuring 105°,80°and 45°.What is the measure of the fouth angle?​
valentina_108 [34]

The measurement of fourth angle is: 130°

Further explanation:

Let A, B, C and D be the four angles.

m∠A=105°

m∠B=80°

m∠C=45°

We know that the sum of interior angles of a quadrilateral is 360°

So,

m∠A+m∠B+m∠C+m∠D=360°

105°+80°+45°+m∠D=360°

230°+m∠D=360°

m∠D=360°-230°

m∠D=130°

The measurement of fourth angle is: 130°

Paul graphs the equation y = 2x where does the graph intersect the y axis
MakcuM [25]

Answer:

(0,0)

Step-by-step explanation:

Y = 2x is a <u>proportional</u> relationship because it follows the form y = kx, where k = constant of proportionality. Proportional relationships intersect the y-axis at (0,0), thus having a y-intercept of 0, but we usually don't write the 0.

Given the information above, y = 2x intersects the y-axis at (0,0), the origin.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
