Answer:

1. Evaluate 3y - 4 for y =5

3*(5)-4=15-4=11

2. 65 + x = 99 x = ?

65+x=99

x=99-65

x=34

3. Find the product. 38.7 *21

38.7*21=812.7

4. Which value satisfies the equation? 9x + 3 = 30

The right value for x would be:

9x+3=30

9x=30-3

9x=27

x=27/9=3

Which is a greater slope 3 or -4

castortr0y [4]

Answer:

3 is greater than -4, but the line with slope -4 is steeper than the line with slope 3.

Step-by-step explanation:

3 is greater than -4, so strictly speaking, a slope of 3 is greater than a slope of -4.

On the other hand, the steepness of a line depends on the absolute value of the slope.

|3| = 3

|-4| = 4

Since 4 > 3, the line with slope -4 is steeper than the line with slope 3.

Answer: 3 is greater than -4, but the line with slope -4 is steeper than the line with slope 3.

I need help<br> If you know this answer plz give it ta meh

Oksana_A [137]

Answer:

4.9 units

Step-by-step explanation:

We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.

a being 4, and b being 3.

We need to use the Pythagorean Theorem to solve this.

$a^2 + b^2 = c^2$

we can rewrite this as;

$4^2 + 3^2 = c^2\\$

Calculation time

15 + 9 = c

c = 24

Now we find the square root of each equation to determine what $c^2$ is.

$\sqrt{15}+\sqrt{9}=\sqrt{24}$

4 + 3 = 4.89897948557

Let's round that to the nearest tenth.

4.9 units

Hope this helped :)
