Answer:
58
Step-by-step explanation:
Ok So do you see the right angle square that equals 90 so all you have to do is subtract 32 from 90 which is 58
For the function f(x) = x^2+10, find the equation of the tangent line at x=-8
2y+18=42
2y=24
y=12
Hope this helps!
Answer:
x =1 for the first problem
and for second question
Step-by-step explanation:
Let's solve your inequality step-by-step.
|2x+5|>0.5
Solve Absolute Value.
|2x+5|>0.5
We know either2x+5>0.5or2x+5<−0.5
2x+5>0.5(Possibility 1)
2x+5−5>0.5−5(Subtract 5 from both sides)
2x>−4.5
2x2>−4.52(Divide both sides by 2)
x>−2.25
2x+5<−0.5(Possibility 2)
2x+5−5<−0.5−5(Subtract 5 from both sides)
2x<−5.5
2x2<−5.52(Divide both sides by 2)
x<−2.75
Answer:
x>−2.25 or x<−2.75
The value of x is -2 and the value of y is -1.
Step-by-step explanation:
Step 1; The given equations are taken as
-3y -9x =21 or -9x -3y = 21, take this as equation 1
-18x +4y =32, take this as equation 2
Step 2; We multiply equation 1 with 2 and equation 2 with 1 so we can cancel out the variable x in both equations. By doing this we get
-18x -6y =42, take this as equation 3
-18x +4y =32, this is the same as equation 2
If we subtract 3 with 2, we cancel out the x variable and can calculate the value of y.
10y = -10 , y = -10/10 = -1
Step 3; Substituting this value of y in any of the previous equations we will get x's value. Here this value of y is substituted in equation 2.
-18x +4(-1) =32, -18x -4 = 32 , -18x = 36, x=-2.
So we have x = -2 and y = -1.
