Answer:
Eva's age is 44 years
Step-by-step explanation:
Let
x ----> Brita's age
y ----> Eva's age
we know that
The sum or their ages 118
so
----> equation A
The difference in age between Brita and her daughter Eva is 30 years
so
----> equation B
Solve the system by elimination
Adds equation A and equation B
<em>Find the value of y</em>
substitute the value of x in any equation
therefore
Eva's age is 44 years
Answer: The constant is -4 cause it will never change from x or y value.
Step-by-step explanation:
To solve this question we need to add 1hr 30mins onto 7:00 am:
1 hour later would be 8:00 am
30 mins later would be 8:30 am
You will get to school at 8:30 am
Hope this helps!
64 different ways
what you do is take the number of different ways and multiply it by all of the other possibilities but since the only number is 8 you would do 8×8=64
Step-by-step explanation:
try the option shown in the attachment.
Finally,
in order to calculate the points E & F it is needed to solve the equations y=2*0+5 and 2x+5=0;
in order to calculate the vertex G it is needed to find x-coordinate:
x=(-4)/(2*1)=-2 and to substitute x=-2 into y=x²+4x-1 (y=-5).
