Answer:
b and d
Step-by-step explanation:
The ways you can tell that there is no solution to a system of equations are:
B. The equations have the same slope and have different y-intercepts.D. The graph of the system shows parallel lines.A linear equation is represented as:
[tex]y = mx+c[/tex]
Where:
m represents the slopec represents the y-interceptWhen the equations in a system of linear equation has the same slope, then the equations are parallel, and they have no solution.
Hence, the true statements are (b) and (d)

In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc
Answer:
[tex]\angle BDC=80^{\circ}[/tex]
Step-by-step explanation:
We are given that
[tex]\angle ABC=69^{\circ}[/tex]
[tex]\angle ACB=31^{\circ}[/tex]
We have to find the angle BDC.
In triangle ABC
Sum of interior angles of triangle=180 degrees
[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]
[tex]69+31+\angle BAC=180[/tex]
[tex]100+\angle BAC=180[/tex]
[tex]\angle BAC=180-100[/tex]
[tex]\angle BAC=80^{\circ}[/tex]
[tex]\angle BAC=\angle BDC=80{\circ}[/tex]
Angles subtended on the same are ac are equal.

Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?
2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

a) Si el área de uno de los rectángulos
es de 156 cm2, ¿Cuáles son sus
dimensiones?
Answer:
El problema parece incompleto, asi que lo respondere en una forma general.
Sabemos que para un rectángulo de largo L y ancho W, el área se calcula como:
A = L*W
En este caso, sabemos que el área del rectángulo es:
A = 156cm^2
Entonces tenemos:
156cm^2 = L*W
No tenemos más información del rectángulo, entonces solo podemos llegar a algo como:
L = (156cm^2)/W
Que nos habla de la relación entre el largo y el ancho del rectángulo.

i need help i don understand i got b but it said it was wrong .
Answer:
b is 135 and c is 45.................thanks
Answer:
[tex]b=135\\c=45[/tex]
Step-by-step explanation:
The angle that measures 135 degrees and angle b are opposite angles. Opposite angles are congruent. Therefore, angle b=135.
[tex]b=135[/tex]
A straight line has an angle measure of 180 degrees. This means that 135+c would equal 180 degrees.
[tex]135+c=180[/tex]
Subtract both sides by 135
[tex]135+c-135=180-135\\c=45[/tex]

Write an expression that is the product of two factors and is equivalent to - 2x - 16.
Which expression is the product of two factors and is equivalent to - 2x - 16?
O A. -2x-1-15
OB. -2(x-8)
OC. (8x - 1)-(10x-15)
OD -2(X + 8)
Answer:
D
Step-by-step explanation:
Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.
Answer B does not work, as when it is multiplied out, we get -2x + 16.
When we find the product of D, we distribute the negative and get the correct product, -2x - 16

Answer:
formula
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Step-by-step explanation:
choose two point of A, let k(-2, -3) and l(1, 3)
[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]
choose two point of B, let c(0, 5) and d(5, 0)
[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]
Hence the gradient of A is

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answer:
it may be B but I think it's C
Step-by-step explanation:
not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides
Both triangles are congruent by (SAS) side-angle-side postulate.
The correct option is B.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.
Given,
Two triangles
ABC and DEC
AB = DE (Given)
BC = EC (Given)
∠ACB = ∠DCE (Vertical angles at intersection of DB and AE)
By, Side-Angle-side theorem of congruent triangles,
ΔABC ≅ΔDEC
Hence, by side-angle-side (SAS) postulate, both triangles are congruent.
