If y=5x - 3 find the value of y when X = 0

1 answer:

8 0

Since we know y=5x - 3 and we know that x=0 then its a matter of plugging in what we know and simplifying. y=5 x 0 - 3 we need to remember the order of operations for this problem. PEMDAS parenthesis exponent multiply divide add subtrac. Since 5 time 0 is multiplication and multiplication comes before subtracting in the oder of operations we will solve that first. 5 times 0 equals 0 since anything times 0 is 0. All that's left is to subtract 3 which gives us y=-3 <span />

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .

$y-(-1)=-2 (x-5)$

$y+1=-2(x-5)$

This is the equation of the line with slope -2 that passes through (5,-1).

Find the value of Z.<br> A)7<br> B)9<br> C)11<br> D)12

Gala2k [10]

As per the isosceles triangle theorem, if the two base angles are congruent then the legs are also congruent, so we must set the two legs equal to each other:

2z - 15 = 9

Add 15 to both sides:

15 - 15 = 0
15 + 9 = 24

Divide 2 from each side:

2z = 24

2z/2 = z

24/2 = 12

z = 12

Hence, the answer would be D: z = 12

Quadratic equation

Murrr4er [49]

Answer:

Step-by-step explanation:

x - age of a son three years ago

3x - age of a father three years ago

x + 3 - age of the son now

3x + 3 - age of the father now

x + 3 + 5 - age of the son in five years time

3x + 3 + 5 - age of the father in five years time

in five years time, the father will be twice as old as his son, so:

3x + 3 + 5 = 2(x + 3 + 5)

3x + 8 = 2x + 16

3x - 2x = 16 - 8

x = 8

x + 3 + 4 - age of the son in four years time

8 + 3 + 4 = 15

3x + 3 + 4 - age of the father in four years time

3×8 + 3 + 4 = 31

the sum of their ages in four years time:

15 + 31 = 46
