Find the area of a triangle that has a base of 5 in and a height of 3 3/4 in

Answers

Answer 1

Answer: Remember:

$3(3)/(4)=(15)/(4)$

Area of a triangle

$A=(1)/(2).b.h\n \n A=(1)/(2)*5*(15)/(4)=(75)/(8)=9(3)/(8) \ in^2$

Answer 2

Answer: $Area= (bh)/(2) \n \n 5*3.75=18.75 \n \n (18.75)/(2) = 9.375 \n\n\boxed{9.375}$

For which function is the ordered pair (4, 12) not a solution?y = 3x
y = x + 8
y = 16 - x
y = 8 - x

Answers

It's D since 8 - 4 = 4, not 12.

Answer:

Y=8-x

So the answer is in fact D.

Percy solved the equation x2 + 7x + 12 = 12. His work is shown below. Is Percy correct? Explain.

Answers

Percy is not correct because he applied the zero product property to a factored expression that was not equal to 0. He should have subtracted 12 from both sides to get x2 + 7x = 0 before factoring. The correct solutions are 0 and -7

What does Percy's work look like?

What is the slope-intercept equation for the line below?

Answers

Answer: D

Step-by-step explanation:

If we look at the graph we can see that the line intercepts the y-axis at (0,-4), so the intercept must be -4.

If we use the rise-over-run formula for (0,-4) and (4,1) we would get:

$(1--4)/(4) \n\n=(5)/(4)$

Since the line is going upwards, the equation must be positive.

Therefore, the equation in slope-intercept form is y=5/4x-4.

Answer is D

First, we can eliminate option b and c because they are negative, and the line in the graph is goin up.
Then you count and get that the m is 5/4, put it together: y=5/4x-4
