When using substitution to solve this system of equations, what is the result of the first step?
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Hope this helps you
Answer:
Solve. Because now you have only one variable.

Answer:
A. 16°
Step-by-step explanation:
Angle E corresponds to angle N, the third angle in ∆MNO. Its measure is ...
∠N = 180° -∠M -∠O
∠N = 180° -99° -65°
∠N = ∠E = 16°

=cosA
solve the inequality 4x-1>15 but the > has a line under it .
Answer:
x ≥ 4
Step-by-step explanation:
Given the inequality 4x-1≥15
Add 1 to both sides
4x-1+1≥15+1
4x≥16
Divide both sides by 4
4x/4 ≥ 16/4
x ≥ 4
Hence the solution is x ≥ 4

Answer:
30
Step-by-step explanation:
you can turn it into 9>sqrt(n)>7 (you have to change the directions of the inequalities since 7>sqrt(n)>9 is just false since 7 is clearly smaller than 9)
81>n>49 since n can't be negative

Answer:
[tex] r = 6\sqrt{3} [/tex]
Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]
Multiply both sides by 36
[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]
[tex] 540 \pi = 5\pi * r^2[/tex]
Divide both sides by 5π
[tex] \frac{540 \pi}{5\pi} = \frac{5\pi * r^2}{5\pi} [/tex]
[tex] 108 = r^2 [/tex]
[tex] r = \sqrt{108} [/tex]
[tex] r = \sqrt{36*3} [/tex]
[tex] r = 6\sqrt{3} [/tex]

Fill in the blanks below in order to justify whether or not the mapping
shown represents a function.
first bank says , the mapping diagram above { represents } or does { NOT represent } a function since ..
blank 2 says { for each number } or { there is one number }
blank 3 says { set a the output } or { set b the input } or { set a the input } , and { set b the output } !
1) it's a function 2) for each number 3) set a input and set b output
to be a function, no ordered pairs should have same first coordinate, hence this is a function
Find the value of c so that (x+3) is a factor of the polynomial p(x). p(x)=x^3-4x^2+cx+33
Answer:
The value of c is -10.
Step-by-step explanation:
Since (x+3) is a factor of the polynomial p(x).
We have that:
x + 3 = 0 -> x = -3
So p(-3) = 0
Then
[tex]p(x) = x^3 - 4x^2 + cx + 33[/tex]
[tex](-3)^3 - 4(-3)^2 - 3c + 33 = 0[/tex]
[tex]-27 - 36 - 3c + 33 = 0[/tex]
[tex]3c = -30[/tex]
[tex]c = -\frac{30}{3}[/tex]
[tex]c = -10[/tex]
The value of c is -10.
