Which constants could each equation be multiplied by to eliminate the x-variable using addition in this system of equations? 2 x
Sever21 [200]

Answer:

3. The first equation can be multiplied by 3 and the second equation by 2.

Step-by-step explanation:

2 x + 3 y = 25 (1)

-3 x + 4 y = 22 (2)

Multiply equation (1) by 3 and (2) by 2.

3(2x) = 6x

2(-3x) = -6x

When you add the two equations, x will get cancelled last

On a coordinate plane, a line is drawn from point a to point b. point a is at (negative 8, negative 13) and point b is at (4, 11
vladimir2022 [97]

The coordinate for point P which is one-third the length of the line segment from a to b is (-4, -5)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Point a is at (-8, -13) and point b is at (4, 11). Hence the coordinates for point p(x, y) which is one-third the length of the line segment from a to b is:

x=\frac{1}{3}(4-(-8))+(-8)=-4\\ \\y=\frac{1}{3}(11-(-13))+(-13)=-5

The coordinate for point P which is one-third the length of the line segment from a to b is (-4, -5)

Parker reviews his homework before he turns it in. When he sees the equation 1.02 divided by 0.6= 0.17, he knows it is wrong. He
HACTEHA [7]

Answer:

The result of the division of a number by a fraction is larger than the fraction.

Step-by-step explanation:

Here,we note that value Parker divided by 0.6. =1.02

Written down result of the division = 1.02/0.6 = 0.17

However, since the numerator is 1.02, then the result of dividing it by a fraction should yield a higher number instead of 0.17

Therefore we check as follows

1.02/0.6 = 1.7

The error is apparently due to dividing 1.02 by 6 rather than 0.6
