Answer:
No Solutions
Step-by-step explanation:
The two lines never intersect
Answer:
A
Step-by-step explanation:
y = 5x + 6 → (1)
y - 5x = 7 ( add 5x to both sides )
y = 5x + 7 → (2)
Substitute y = 5x + 7 into (1)
5x + 7 = 5x + 6 ( subtract 7 from both sides )
5x = 5x - 1 ( subtract 5x from both sides )
0 = - 1 ← is False
This indicates the system has no solution
What is the value of 2/3(x-6)-Y when x = 9 and y = 5/6?
Replace x and y with the given values:
2/3(9-6) - 5/6
Simplify:
2/3(3) - 5/6
Multiply:
2 - 5/6
Subtract:
1 1/6
Answer 1 and 1/6
The required simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.
To find the value, substitute the given values of x and y into the expression:
2/3(x - 6) - y
= 2/3(9 - 6) - 5/6
= 2/3(3) - 5/6
= 2 - 5/6
To subtract fractions, you need a common denominator:
= 12/6 - 5/6
= 7/6
Therefore, the simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

A quadratic function y = f(x) is plotted on a graph and the vertex of
the resulting parabola is (3, -5). What is the vertex of the function
defined as g(x) = f(-x) + 3?
Answer:
the vertex is (0,3)
Step-by-step explanation:
using vertex form: y=a(x-h)^2+k you can find the vertex
h: the horizontal <----------->
and
k: the vertical |
so, there is no h, but there is a k, which is 3, so the answer is (0,3) I believe
Algebra one please help
Answer: a
Step-by-step explanation: In the picture
please give me a brainliest answer
Step-by-step explanation:
just look at the graph and check the typical "special" points.
e.g. when x = 0, and when y = 0, and maybe (depending on the curve) some other interesting ones.
so, what does the graph tell for x = 0 ?
it says y = 5.
that rules out C and D, because they would deliver y = 1/5 for x = 0.
so, it can only be A or B.
now, what does the graph tell us for y = 0 ?
ok, it tells us, x = 1.
that does not help us in this case, as both, A and B deliver y = 0 for x = 1
so, let's look at another good point. good points are points, where we can see pretty precisely their coordinates on the chart, and where these coordinates are even integer numbers.
I see e.g.
x = 2, and y = -5
let's try A
-5 = -5 × cubic root(2 - 1) = -5 × cubic root (1) = -5×1 = -5
so, -5 = -5, that is correct.
let's verify by checking also B
-5 = 5 × cubic root (1 - 2) = 5 × cubic root (-1) = 5×-1 = -5
-5 = -5, again, this is correct.
hmmmmm.
when we think about it, in fact, A and B are the same function (by the way, C and D are equal to each other too).
either your teacher made a mistake or tried to trick you.
A and B are both the right answer.
why ?
A (I only write "cr" for cubic root now)
y = -5 × cr(x - 1) = 5 × -1 × cr(x - 1) = 5 × cr((-1)³(x - 1)) =
= 5 × cr(-1 × (x - 1)) = 5 × cr(x×-1 - 1×-1) = 5 × cr(1 - x) = B
so, A and B are actually equal.
Which of the following is a function equivalent
[tex]f(x) = 4 {(1.8)}^{2x} [/tex]
a.
[tex]f(x) = 4 {(3.24)}^{x} [/tex]
b.

c.
[tex]f(x) = {12.96}^{x} [/tex]
d.
[tex]f(x) = {51.84}^{x} [/tex]
Answer:
The correct result would be f(x) = 4(3.24)x.

Genie is making cookies and brownies. Each cookie uses 8 grams of flour and each brownie uses 12 grams of flour. She wants to make more than 125 cookies and brownies altogether. If Genie has a total of 2,000 grams of flour, which system of inequalities models correctly the number of cookies, c, and brownies, b, she can make? ) C+b> 125 A) 8c + 12b s 2000 c+b2 125 8c + 12b s 2000 B) c+b< 125 C) 8c + 12b s 2000 c+bs 125 D) 8c + 12b s 2000
The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000
Let c represent the number of cookies and let b represent the number of brownies.
Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:
c + b ≥ 125 (1)
Also, Genie has a total of 2,000 grams of flour, hence:
8c + 12b ≤ 2000 (2)
Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Find the length of the third side. If necessary, round your the nearest tenth.
Answer:
24
Step-by-step explanation:
Use Pythagorean theorem,
base² + altitude² = hypotenuse²
7² + altitude² = 25²
altitude² = 25² - 7²
= 625 - 49
= 576
altitude = √576
altitude = 24
_________
[tex] \: [/tex]
b² = c² - a²
b² = 25² - 7²
b² = 625 - 49
b² = 576
b = √576

Step-by-step explanation:
shape BCD is an isosceles triangle meaning the base angles will be the same.
CA is a straight line meaning that it is 180
the sum of angles in a triangle always is 180
so
180-36= 144
to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.
144/2= 72
x=72
the angle just below y is also 72.
as CA is a straight line,
180-72= 108 giving you the answer for y
y= 108
so to make the answer clear
x= 72
y= 108

Write a possible polynomial function in factored form with roots 0, -2, and 7. Group of answer choices
f(x)=(x+1)(x+2)(x−7)
f(x)=x(x+2)(x−7)
f(x)=x(x−2)(x+7)
f(x)=(x+2)(x−7)
Answer:
2nd option
Step-by-step explanation:
Given x = a is a root of a polynomial function then (x - a) is a factor
Given roots are x = 0, x = - 2, x = 7 , then corresponding factors are
(x - 0) , (x - (- 2) ) , (x - 7) , that is
x , (x + 2) , (x - 7)
The polynomial function f(x) is then the product of the factors, so
f(x) = x(x + 2)(x - 7)
