Answer:
Step-by-step explanation:
Let's solve for x.
5x−2y≤20
Step 1: Add 2y to both sides.
5x−2y+2y≤20+2y
5x≤2y+20
Step 2: Divide both sides by 5.
5x /5 ≤ 2y+20 /5
x≤ 2 /5 y+4
Answer:
x≤ 2 /5 y+4
Let's solve for y.
5x−2y≤20
Step 1: Add -5x to both sides.
5x−2y+−5x≤20+−5x
−2y≤−5x+20
Step 2: Divide both sides by -2.
−2y /−2 ≤ −5x+20
−2 y≥ 5 /2 x−10
Answer:
y≥ 5 /2 x−10

In the transformed quadratic function
vertex point is
g(x) = 3(x – 5)2 - 4 , the
O (5, 4)
O (3, -4)
o (-5, -4)
(5,-4)
Answer:
(5, -4)Step-by-step explanation:
f(x) = a(x - h)² + k ← the vertex form of quadratic function where vertex is: (h, k)
[tex]\left{\big{f(x)=a(x-h)^2+k}\atop \big{g(x)=3(x-5)^2-4}\right\}\implies a=3\,,\ \underline{h=5\,,\ k=-4}[/tex]

how do you solve this pls help!!!
Answer:
y = 1
x = -0.75
Step-by-step explanation:
The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.
21y - 1 = 4x + 23
21y - 24 = 4x
5.25y - 6 = x
21y - 1 = 4x + 23
21y = 4x + 24
y = 4/21(5.25 - 6) + 1.14
y = 1 - 1.14 + 1.14
y = 1
5.25(1) - 6 = x
-0.75 = x

Step-by-step explanation:
hi! we can start off by plugging in the number 9 for x in the equation.
f(x)=8x-11)
f(9)= 8(9)-11
= 72-11
=61

One solution to a quadratic equation is x = 1 + 8i. What is the other solution?
We'll assume the quadratic equation has real coefficients
Answer:
The other solution is x=1-8i.
Step-by-step explanation:
The Complex Conjugate Root Theorem
if P(x) is a polynomial in x with real coefficients, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).
The question does not specify if the quadratic equation has real coefficients, but we will assume that.
Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
Answer:
the answer would be x= 1-8i

The function
has the same amplitude as the function y = cos(x – 4) + 1.
The function
is a translation of the parent cosine function.
Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3
Step-by-step explanation: just took it
Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].
Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -
The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:
[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].

Identify the slope and y-intercept from the following equation.
Answer:
The slope is 2/5 and the y intercept is -4
Step-by-step explanation:
The slope is always the coefficient to x
Answer:
slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4

Problem 10
Answer: 80 degreesWork Shown: 80-0 = 80
You subtract the values on the protractor where the two angle arms line up.
============================================
Problem 11
Answer: 45 degreesWork Shown: 45-0 = 45
Same idea as problem 10
============================================
Problem 12
Answer: 83 degreesWork Shown: 128-45 = 83
Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.
============================================
Problem 13
Answer: 35 degreesExplanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
