Answer:
d:15
Step-by-step explanation:
since the angles are equal to each other, then the sides must be equal to each other too
so...
3x+5=4X-10
15=x
The correct answer is A) a translation 2 units right and 4 units down.
Both of the reflections listed would keep the digits but change their signs and/or placement.
A translation 2 units right subtracts 2 from the x-coordinate. A translation 4 units down subtracts 4 from the y-coordinate. Comparing each pre-image point to its image, we can see that is what happened.
1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)
The union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
<h3>What is a set?</h3>
A set is simply a mathematical model for a collection of different things which could be elements or members.
Union of sets represented with '∪' is the combination of two sets without repetition
Intersection of sets represented with '∩' is the sum of elements common between the.
From the expression given, we have;
[-9,-4] U (-4, 19)
= { -4, -9 , 19}
[-9,-4] U (-4, 19)
= { -4}
Thus, the union and intersection of the sets is given as { -4, -9 , 19} and { -4} respectively.
