The slope-intercept equation for a straight line as - 3 x + 10.

Slope refers to a number that describes both the direction and the steepness of the line.

The slope-intercept equation for a straight line is given by:

y = m x + b;

where m = the slope and b = the y-intercept.

Here, we are given that:

m = slope = -3

y- intercept = b = 10

Put it in the equation y = m x + b, we get that:

y = (-3) x + 10

y = -3 x + 10.

Therefore, we get the slope-intercept equation for a straight line as - 3 x + 10.

PLSSS HELPPP I AM SO CONFUSED AND STUCH HOW TO THIS il mark you as brainlist its about volume and percents

Oliga [24]

First we find the volume of the triangular prism.

We find the area of the triangle, then we multiply that by the height.

So 7*6/2= 42/2=21

21*10= 210

Then if all the dimensions add another foot on to them then you get: 7, 8, and 11.

Then you do the same thing to find the area of this rectangular prism.

7*8/2=56/2=28

28*11= 308

Now, we calculate the growth from 210 to 308 in this proportion: 308/210=x/100

Solving it we get (cross multiplying):

210x=30800

x=146 2/3 or 146.66 percent increase.

I hope this helps!

Depending on a given set of conditions and the properties of triangles, any of these four outcomes is possible when constructing

Dennis_Churaev [7]

Answer:

Part A

the dotted line formes the thrid side of the triangle.

part B

The length is the unknon side increases while kepping the known side lenths fixed, measuremnt of anggle Z will increas. So, the tringle will not fir the given conditions anymore.

part c

If the length of he unknown side decrases while keeping h known side lengths fixed,the measure of angle will decrease so he tringle will not fit the given conditions anymore.

part D

You know the given conditions for the triangle are fixed you also know the unknown side length is fixed. What dose the this tell you angles adjacent to the unknown side.

part e

The given condiction are fixed and the unknown side lenghtis fixed, the angles adjacent to the unknown side must much also be fixed.

part f

Given two side lengths and the measurement of the angle between them, only one triangle can be constructed. Part G The length of the unknown side (c) is 9.76 centimeters

Isaac drove at an average speed of 49 mph over six hours. During the first three hours he drove at a speed that was 172 mph less

Over [174]

Issac drove the first three hours at 44 miles per hour.

Step-by-step explanation:

Given,

Average speed of Isaac = 49 mph

Let,

x be the speed during last three hours.

Speed during first three hours = 4x-172

Average = $\frac{Sum\ of\ terms}{No.\ of\ terms}$

$49=\frac{(4x-172)+x}{2}\\\\49=\frac{4x-172+x}{2}\\\\49=\frac{5x-172}{2}$

Multiplying both sides by 2

$49*2=\frac{5x-172}{2}*2\\98=5x-172\\98+172=5x\\270=5x\\5x=270$

Dividing both sides by 5

$\frac{5x}{5}=\frac{270}{5}\\x=54$

Speed during last three hours = x = 54 mph

Speed during first three hours = 4x-172 = 4(54)-172 = 216-172 = 44 mph

Issac drove the first three hours at 44 miles per hour.

Solve for x: -2x - 4> 8 (1 point)

UkoKoshka [18]

draw a line through the greater than sign then you start by added for to both sides so -4 + 4 is equal to 0 8 + 4 is equal to 12 so now -i -2 goes into 8 -6 * so that means X is greater than -6
