Evaluate a + 4 when a = 7

Asnwer for brainliest !!! <33

ANEK [815]

Answer:

24

Step-by-step explanation:

Let's do the smaller parts at the edge.

The formula for a triangle is 1/2bh

The base is 3 the height is 4

3 times 4 is 12

12 divided by 2 is 6

Since there are two of the same triangle on the edge both of the triangle's area is 6 which is 12

No for the upper triangle, the base is 6 and the height is 4

4 times 6 is 24

24 divided by 2 is 12

12 plus 12 is 24

The answer is

The area of the shaded parts of the triangle is 24 in^2

Hope this helps!

Solving systems by Substitution Homework y=x+4 y=x-3

zvonat [6]

There is no solution for this equation since they have the same slope, x/1. The only difference between these two is that their y intercepts are different meaning that they will be parallel lines that will never intersect among one other. For example, think of it as two separate lines that are have the same slope and never gain more distance/units from one another.

Solve:

To solve, you have to get one of this equations into a Ax+By=C equation form, standard equation. Let’s change y=x+4 into a standard equation.

We have to get x and y together and 4 as C.
So let’s subtract x from both sides;

y=x+4
-x -x
————————
-x+y=4

This is a standard equation.

Now let’s substitute.

take the standard equation and plug in y which is x+4 since there is a equation meaning it’s y=x+4

-x+(x+4)=4

Let’s simplify this mess.

-x+x equals 0. So we are left with 4=4.

Subtract 4 from both sides and we get 0=0

This means there is no solution. Hoped this helped.

Help PLEASE!! This is my last question of this QUIZ THAN I'LL BE FREE!!<br> 20 pts!!!!

EastWind [94]

Answer:

y=0.012x+0.65

Step-by-step explanation:

And again y=mx+c

we have 4 point given in the question

(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)

we can find the M ( gradient/Slope) by using 2 of them with the formula

I am using the first 2 (50,1.25) ( 100,1.85)

$\frac{y2-y1}{x2-x1}$

$\frac{1.85-1.25}{100-50} \\\frac{0.6}{50}$

which in decimal form is 0.012

with that cross out the first option as its wrong

now to find c, like in the previous two question, put the m, x and y in the equation and solve for C

I am gonna use the 3rd coordinates for this one (150,2.45)

2.45=0.012(150)+c

2.45=1.8+c

0=1.8-2.45+c

-c=-0.65

c=0.65

So our completed equation is y=0.012x+0.65

The third answer is correct :)
