Answer:
true
Step-by-step explanation:
Answer:
x = -2
y = 5
Step-by-step explanation:
2x - 3y = -19 ---------------------------(I)
7x+ 7y = 21 -----------------------------(II)
Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x
(I)*7 14x - 21y = - 133
(II)* 3 <u> 21x + 21y = 63 </u> {Now add}
35x = -70
x = -70/35
x = - 2
Plug in x = - 2 in equation (I)
2*(-2) - 3y = -19
-4 - 3y = -19
-3y = -19 + 4
-3y = -15
y = -15/-3
y = 5

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
A pumpkin pie recipe says to bake the pie at 425°F for 15 minutes, and then to adjust the temperature down to 350°F for 45 additional minutes.
The function P(t) gives the oven temperature setting t, in degrees Fahrenheit, t minutes after the pie is placed in the oven.
Diego discovers that the temperature inside the oven is always 25 degrees warmer than the oven’s temperature setting.
The function B gives the actual temperature of Diego’s oven.
If P(30) = 350. Then the corresponding point on the function B will be
The temperature function can be written as

The value of t = 30 lies in the interval of 15 < t ≤ 60.
After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.
