Answer:
x = 5
Step-by-step explanation:
given the equation
4x + 10 = 30 ( subtract 10 from both sides )
4x + 10 - 10 = 30 - 10 ( simplify both sides )
4x = 20 ( divide both sides by 4 )
x = , that is
x = 5
i just want to see if i got the correct answer my answer was
b=-15
Yes, the answer to the given maths solution is indeed is b = -15
3(-15) = -45
-45 + 9 = -36
-36 - 16 = -52
so b = -15
Hence, your initial answer is correct.

Answer:
yes, the answer is b = -15
Step-by-step explanation:
3(-15) = -45
-45 + 9 = -36
-36 - 16 = -52
so b = -15
Answer:
Option a is correct.
Step-by-step explanation:
We have been given the expression:
We will factorize the given quadratic equation:
Hence, the given equation is equivalent to (x+8)(x+3)
Hence, the graph will be equivalent to y=(x+8)(x+3)
Therefore, option a is correct.
Answer
The option B is the right answer because the vertex is (4,3)
Step-by-step explanation:
In the canonical equation of the parabola:
(X-h) ^ 2 = 4p (y-k)
The values (h, k) correspond to the coordinates (x, y) of the vertex.
In the definition of the problem it is said that the guideline of the parabola is the X axis, that is, the line Y = 0 and the focus is the point (4,6).
If the vertex were the point (4.6) the correct option would be option D
But the vertex is located at the midpoint of the segment defined by the focus points (4, 6) and the point (4, 0) that is on the parabola directrix. therefore, as the vertex is the point (4.3). the correct option is B.
B. Stretching
C. Shrinking
D. Reflecting
E. Translating
The answer choices which represent congruencetransformations are; Choice A; Rotating, Choice D; Reflecting and Choice E; Translating.
According to the task content; it follows that the answer choices which represent congruence transformations be identified.
Congruence transformations are simply characterized by the fact the size of the object undergoing transformation remains unchanged after transformation. Hence, such congruence transformations are as identified above.
