Answer:
5
Step-by-step explanation:
f(-5)=-(-5)^2 - 7(-5) - 5
f(-5)= -25 +35 - 5
f(-5) = -25 +30
f(-5) = 5
Answer:
the answer is confusing but you have to put it in as an equation and get and answer then you simplify that answer into a number sequence by rounding and estimating
Step-by-step explanation:
Answer: 56 degree
Step-by-Step Explanation:
Let measure of unknown angle be ‘x’
One angle = 68 degree
Sum of all angles is 180 => 68 + 2x = 180
Therefore,
68 + 2x = 180
2x = 180 - 68
2x = 112
x = 112/2
=> x = 56
Therefore, the measure of the missing angles is 56 degrees each.

Answer:
The values of x and y in the diagonals of the parallelogram are x=0 and y=5
Step-by-step explanation:
Given that ABCD is a parallelogram
And segment AC=4x+10
From the figure we have the diagonals AC=3x+y and BD=2x+y
By the property of parallelogram the diagonals are congruent
∴ we can equate the diagonals AC=BD
That is 3x+y=2x+y
3x+y-(2x+y)=2x+y-(2x+y)
3x+y-2x-y=2x+y-2x-y
x+0=0 ( by adding the like terms )
∴ x=0
Given that segment AC=4x+10
Substitute x=0 we have AC=4(0)+10
=0+10
=10
∴ AC=10
Now (3x+y)+(2x+y)=10
5x+2y=10
Substitute x=0, 5(0)+2y=10
2y=10

∴ y=5
∴ the values of x and y are x=0 and y=5
