Answer:

23

Step-by-step explanation:

So, since angle 1 and angle 2 are complimentary, ( meaning that they will both add to equal 180 degrees), you can do what I did:

180-81=99

99+30=69

69/3=23

X=23

Xavier has $23.50 in his savings account. He deposits $35 every week. His mother also deposits $20 into the account every time X
svlad2 [7]
A. A coefficient is a constant multiplied with a variable. Example is 20 for 20c and 35 for 35w. A variable is expressed in numerical letters like cfor 20c and w for 35w. A constant is merely a number, like 23.50.

b. w = 12, c = 3; substitute these values to the given equation :
20c+35w+23.5 = ?
20(3)+35(12)+23.5 = $503.5

c. The expression would change for the term 20c. Instead of 20c,it would then be changed to 25c. Note that the equation was made from the problem statement. If one statement changes, then the mathematical terms would be affected. The rest of the other terms would remain as is.

Change the equation of the line to slope-intercept form. 6x + 2y =10 *
allsm [11]

Answer:

Solve for y.

Step-by-step explanation:

6x+2y=10

6x+2y-6x=10-6x  subtract 6x from both sides.

2y = -6x+10

2y/2 = -6x/2+10/2  divide each term by 2.

y = -3x+5

Hope this helps!

The sides of a triangle are given by the equations 4x-y-7=0,x+3y-31=0 and x+5y-7=0.determine the point of intersection of its al
Nezavi [6.7K]
Hello,

1)Let's call A=inter (4x-y-7=0, x+3y-31=0)
4x-y=7
x+3y=31
==>13x=52==>x=4
and y=4*4-7=9

A=(4;9)

 
2)Let's call B=inter (4x-y-7=0, x+5y-7=0)

4x-y=7
x+5y=7
==>21x=42
==>x=2 and y=4*2-7=1

B=(2,1)

3) Slope of BD: y=-x/3+31/3 ==> slope perpendicular=3

Line BD:y-1=3(x-2)==>y=3x+5

4) Slope AE: y=-x/5+7/5 ==>slope perpendicular=5
Line AE: y-9=5(x-4)==> y=5x-11

5) intersection (BD;AE):
y=5x-11
y=3x-5
==>2x=6==>x=3
and y=3*3-5=4
H=(3,4)
