3x+y=2x+y because 4=4
x=0 because 3x-2x=1x or x and y-y=0
now substitute 0 for x to get y and y=4
the answer is D

Since 3x3⁢x does not contain the variable to solve for, move it to the right side of the equation by subtracting 3x3⁢x from both sides.y=−3x−4y=-3⁢x-4Use the slope-intercept form to find the slope and y-intercept.Tap for more steps...Slope: −3-3Y-Intercept: −4
Multiply −1 - 1 by −2 - 2 to get 2 2 . Multiply 4 4 by −1 - 1 to get −4 - 4 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m ⁢ x + b , where m m is the slope and b b is the y-intercept.

Yolanda’s sunflower plant was 64.34 centimeters tall in July.

Tomtit [17]

It would be 82.54 centimeters tall by the end of August so you would round it up so it would become 83 centimeters meaning that the estimate would be greater than the actual height because you would be rounding up to the nearest whole number not down.

Help,anyone can help me do quetion.

Answer:

(a) x = $128^{o}$

(b) x = $74^{o}$

Step-by-step explanation:

A. sum of angles in a polygon = (n - 2) 180

The polygon given is an irregular pentagon, where n = 5

So that;

sum of angles in a pentagon = (5 - 2) 180

= 3 x 180

= $540^{o}$

Thus,

x + 90 + 76 + 110 + 136 = $540^{o}$

x + 412 = $540^{o}$

x = $540^{o}$ - 412

x = $128^{o}$

B. The polygon given is an irregular pentagon, where n = 5.

Let the supplementary angle with angle 38 be represented by y,

y + 38 = 180

y = 180 - 38

= $142^{o}$

y = $142^{o}$

Let the supplementary angle with x be represented by z, so that;

z + 72 + 120 + 100 + 142 = $540^{o}$

z + 434 = $540^{o}$

z = $540^{o}$ - 434

= $106^{o}$

z = $106^{o}$

But, x + z = $180^{o}$

Then;

x + $106^{o}$ = $180^{o}$

x = $180^{o}$ - $106^{o}$

= $74^{o}$

x = $74^{o}$

Write an equation for the line that is parallel to y = −2x and passes through the point (0,7).

lesya [120]

Answer:

B. $\displaystyle y = -2x + 7$

Step-by-step explanation:

The y-intercept is given to us, which is $\displaystyle [0, 7],$ and Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so −2 remains the way it is.
