Answer:

\left \{ {{y=-1} \atop {x=2}} \right.

Step-by-step explanation:

\left \{ {{5x+4y=6} \atop {-2x-3y=-1}} \right.  \left \{ {{10x+8y=12} \atop {-10x-15y=-5}} \right. \left \{ {{-7y=7} \atop {-10x-15y=-5}} \right.  \left \{ {{y=-1} \atop {-10x-15y=-5}} \right.  \left \{ {{y=-1} \atop {-10x+15=-5}} \right. \left \{ {{y=-1} \atop {-10x=-20}} \right. => \left \{ {{y=-1} \atop {x=2}} \right.

A high school soccer goalie blocked the ball from going into the goal 4 out of 5 times. If the ball kicked toward the goal 25 ti
miskamm [114]
We can use a ratio expression to find the answer to this problem.

Set up the ratio.
4/5 = x/25
Multiply both sides by 25.
100/5 = x
Divide by 5.
20 = x
This means out of 25 times the ball is kicked toward the goal, the goalie will block it 20 times.

A linear function has a y-intercept of -12 and a slope of 3/2. What is the equation of the line?
Natali [406]

Answer:

y = (3/2)x - 12

Step-by-step explanation:

Recall that the general equation for a linear function may be written in slope-intercept form:

y = mx + b

where m = slope and b = y-intercept

In this case, it is given that slope = m = 3/2 and y-intercept = b = -12

substituting these values into the general equation:

y = (3/2)x + (-12)

or

y = (3/2)x - 12

4.07, 4.070, 4.70, 4.0700 what value is not equivalent.
larisa [96]
4.70, all the others can be simplified to 4.07 by taking away the zeroes after the 7 because they are not significant, The one before the 7 stays because it is significant as it is holding the tenths place value.
