(a) find the value of the discriminant
(b) state the number and type of the roots (2 real, 2 imaginary/complex or 1 real).
√44
2 Real Roots
Step-by-step explanation:Looking at the image attached, the discriminant is the value under the square root.
In the equation given:
a = 1
b = -8
c = 5
The discriminant is therefore:
√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44
√44 is a positive number. Because it is positive, there must be 2 real roots.
If it were negative, there would be 2 imaginary roots.
If it were zero, there would be 1 real root.

If the start Time is 8:00 and the end time is 11:00.a.m,what is the elaped time? ?
Answer:
3 hours
Step-by-step explanation:
Use the graph to answer the following…
Answer:
slope = 2 because it goes up by 2 and across 1
10 = 2(1)+b
10=2+b
-2 -2
b = 8
y intercept = 8
equation: y = 2x+8
yes it is proportional because it has a constant rate of change or slope
y+4=-7(x-3)
can someone pls explain I'm so confused? In needs to be in slope int form
Answer:
so slop int form is y=mx+b
so start off by distributing the -7 to the x and -3
so that leave you with y+4=-7x+21
get it all on the same side
y-7x-17
Step-by-step explanation:
Answer:
y = m x + b .
y = − 7 x + 17

How many solutions does the equation 2 + 6(x - 4) = 3x - 18 + 3x have?
A)0
B)1
C)2
D) Infinite
Answer:
C because it's a quadratic equation and it can be solved by factorization and completing the square method and also general formula
Write an equation of the line with the given slope and y-intercept: m = 2, b = negative three-fourths a. y = negative 2 x + three-fourths b. y = 2 x minus three-fourths c. y = negative 2 x minus three-fourths d. y = 2 x + three-fourths
Answer:
y = 2x - 3/4 Answer b
Step-by-step explanation:
slope intercept form is
y = mx + b
m is the slope = 2
b is the y-intercept = -3/4
therefor
y = 2x - 3/4 Answer b

Find the value of X - triangle measurments
I WILL GIVE BRAINLIEST!
Answer:
x = 20Step-by-step explanation:
from how the sides are marked it is an equilateral triangle, to see it does not seem. assuming that it is equilateral it has 3 angles of 60 ° for which 4x - 20 = 60
4x - 20 = 60
4x = 80
x = 80 : 4
x = 20
-------------------
4 * 20 - 20 = 60°

La casa de Camilo está a 4 cuadras a la derecha de la casa de Andrés, la casa de Rodrigo está a 2 cuadras a la izquierda de la casa Camilo ¿Cuántas cuadras hay entre las casas de Andrés y Rodrigo?.
La casa de Rodrigo está dos cuadras a la derecha de la casa de Andrés.
En esta pregunta, debemos leer el enunciado y obtener las ecuaciones equivalentes antes de obtener su solución. En este caso tenemos las siguientes dos ecuaciones:
(i) La casa de Camilo está a 4 cuadras a la derecha de la casa de Andrés.
[tex]c - a = 4[/tex] (1)
(ii) La casa de Rodrigo está a 2 cuadras a la izquierda de la casa de Camilo.
[tex]r - c = -2[/tex] (2)
Si sumamos (1) con (2), entonces obtenemos la siguiente ecuación entre las casas de Andrés y Rodrigo:
[tex]r - a = 2[/tex]
En síntesis, la casa de Rodrigo está dos cuadras a la derecha de la casa de Andrés.

write down the value of
a) 740 × 233
b) 74 x 2.33
Answer:
a) 740 × 233 = 172420
