Plot the intercepts to graph the equation. x+y=3
andrey2020 [161]

Answer:  You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Step-by-step explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3.  Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3  Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.

There are 364 first-grade students in Park Elementary School. If there are 26 more girls than boys, how many girls are there?
wlad13 [49]

Answer:

195

Step-by-step explanation:

If there are x boys, then there are x+26 girls. Hence, we write the equation,

x+(x+26)=364

Solve for x:    

        2x+26=364

            2x-338

             x=169

So there are 169+26 =195 girls

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that repr
NeX [460]

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y  and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.
