Answer:
Y intercept will be -4.
Step-by-step explanation:
Here we are given our function as

We are asked to determine the y intercept.
The y intercept is the y ordinate of the coordinates of the point at which the graph of the function intersects the y axis.
Please note that the point at which graph cuts the y axis have x=0
Hence in order to determine y intercept we need to put x=0 in our function and solve it for y :

Putting x =0



subtracting both sides by 8

dividing both sides by 2
=-4
Answer:
x = 8.45
Step-by-step explanation:
5.4 + 0.2x = 7.09
Subtract 5.4 from both sides to leave 0.2x alone
0.2x = 1.69
Divide by 0.2 on both sides to isolate x
x = 1.69/0.2
x = 8.45
Short leg = ?
Long leg = 1/2x + 11
Hypotenuse = 2x + 1
For this you'd need to use the Pythagorean Theorem to find the short leg.
Pythagorean Theorem - a^2 + b^2 = c^2
The answer is 3.1 cm
Solution:
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
answer is base=3.1 cm
