Answer: Direction opens downward
Step-by-step explanation:
X-Intercept: (1/14,0),(-1/4,0)
Y-Intercept: (0,1)
Find the vertex using x= -b/2a
Plug it into the vertex form = y=a(x-h)^2 +k
H,K will identify the direction.
Answer:
(6, -4) does not fit with these two equations
Step-by-step explanation:
y = 8 - 2x
x + 3y = 12
fit (6, -4) into the equations
-4 = 8 - 2(6)
8 - 2(6) = 8 - 12 = -4
works for this one
6 + 3(-4) = 12
6 + 3(-4) = 6 - 12 = -6
doesnt work for this one
The complete statement is (d) Any rational root of f(x) is a factor of 9 divided by a factor of 12.
<h3>How to determine the rational roots?</h3>
The polynomial is given as:
12x^3 - 5x^2 + 6x + 9
The first term in the above equation is 12 i.e. 12x^3, while the last term is 9
To determine the possible rational roots, we divide the factors of the last term i.e. 12 by the factors of the first term i.e. 12
Hence, the complete statement is (d) Any rational root of f(x) is a factor of 9 divided by a factor of 12.

x+19= 26
x+19-19= 26-19
x= 7
Check answer by using substitution method
x+19= 26
7+19= 26
26= 26
Answer is x= 7 (D.)
Answer:
x=45/6
Step-by-step explanation:
2+7y=8. 7y=8-2. <u>7</u><u>y</u><u>=</u><u>6</u>
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
<em><u>f</u></em><em><u>u</u></em><em><u>r</u></em><em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u>r</u></em><em><u>.</u></em>
<em><u> </u></em>confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
