Answer:

x=3, y=-1

Step-by-step explanation:

We know that lcm(7, 2)=14, so we need to multiply equation 1 by 2.

This gives 2(4x-7y)=2(19), which simplifies to 8x-14y=38.

We know that lcm(2, 7)=14, so we need to multiply equation 2 by 7.

This gives 7(3x-2y)=7(11), which simplifies to 21x-14y=77.

Aha! Now we have a path to the solution!

We can subtract the first equation from the second to eliminate y.

This gives (21x-14y)-(8x-14y)=(77)-(38), which simplifies to 13x=39.

We can then divide by 3 to obtain x=3!

Then, we plug x=3 into the second equation to get 3(3)-2y=11.

We can subtract 9 from both sides to get -2y=2.

We then divide by -2 to obtain y=-1.

So, x=3 and y=-1, and we're done!

Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?
kati45 [8]

Answer:

B

Step-by-step explanation:

Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.

What is the location of the point on the number line that is 2/5 of the way from A = -6 to B = 9
sammy [17]
The distance between is =|9|+|-6|=15.
We can find that
\frac{2}{5}  \times 15 = 6
So 2/5 of the AB segment is 6 distance points away from A at point C=0.

The ratios of the angles in ABC is 3:5:7. Find the<br> measure of the angles
zepelin [54]

Answer:

Step-by-step explanation:

If the ratio of triangle = 3:5:7

Total ratio = 3+5+7 = 15

The sum of angle in a triangle is 180°

1st angle= 3/15× 180 = 3 × 12 = 36°

2nd angle= 5/15 × 180 = 5 × 12 = 60°

3rd angle= 7/15 × 180 = 7 × 12 = 84°
