You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)
Answer:
it is f(x)=x^2+3x-2
Step-by-step explanation:
Answer:
w(t)=0.8t+17.9
Step-by-step explanation:
By reading the question thoroughly you can determine that w is the y axis/y values and t is the x axis/x values.
<em>First we need to find the slope, so we take two sets of coordinates so we can determine the slope. for this we use the following formula:</em>
<em /><em />
So now i am going to use the coordinates (1,18.7) and (2,19.5)
<em>Now i plug in the numbers:</em>
<em /><em />
<em>It is very important that the coordinates do not get mixed up at all and stay with the other value they belong with</em>
<u>Simplify:</u>
<u /> or 0.8/1
Since any number divided by one is itself, we have the slope.
<em>To determine the y intercept, we look at the graph, the x or t value is at 1, so all we have to do is subtract 0.8 from the y value where x=1:</em>
<u>Subtract:</u>
18.7-0.8=17.9
1-1=0
(0,17.9)
<u>Now that we have all of our components, we put the equation together like a puzzle</u>:
w(t)=0.8t+17.9
I hope this helps u pls give a brainliest and a thx ;)
Answer:
um try to type it out bc that made no sense
Step-by-step explanation:
Answer:
Daughter is 25, mother is 58
Step-by-step explanation:
Let m = age of mother now
Let d = age of daughter now
m - 14 = 4(d - 14)
m = 2(d + 4)
m - 14 = 4d - 56
m = 2d + 8
subtracting them gets
14 = -2d + 64
2d = 50.
d = 25
m = 58
