marshall27 [118]

<span>He bought 36 baseball cards. Since 3/4 of the 48 cards are baseball cards, you need to find 75% of 48, which is 36 cards. </span>

1.3z+1.5=5.4<br> Please find Z. You dont have to explain, unless you want to. Thankss

Usimov [2.4K]

Step-by-step explanation:

1.3z + 1.5 = 5.4

Make z the subject in the equation by making it stand alone, by so doing, the transferred figures will have a change in sign i.e if it's a negative sign that's gonna be transferred it will change into a positive sign and vice versa.

The equation will this be; 1.3z = -1.5 + 5.4

1.3z = 3.9

Divide both sides by the co-efficient of the unknown figure. In other words, you'll divide both sides by the number beside the unknown letter.

z = 3.

The question is in the picture

Hoochie [10]

Since you’re dealing with a linear equation in slope-intercept form, we know the equation is going to be in the form of y=mx+b.

Therefore, we need to find the slope (“m”) of the line (change in y/change in x), which is rise/run. We also need to find the y-intercept (“b.”)

1.) (0, -3) (1, -1)
We took two points from the line to find the slope. We will use the 2 coordinate pairs to find the slope.

2.) m=(y2-y1)/(x2-x1)
This is the slope “m” formula.

3.) m=( -1+3)/(1-0)
Input the coordinate values into the formula. The +3 you see is due to -(-3)=+3.

4.) m=2/1
We simplified the above formula.

5.) m=2
By division.

We now have the slope or “m.” M=2. Therefore, the equation rises 2 units and runs 1 unit.

Now, finding the y-intercept:

The y-intercept or “b” is where the line intersects the y-axis. It is the starting point of a linear equation.

To find the y-intercept, we need to figure out what the output is when the input is 0. We can see on the table in the picture that with an input of 0, the output is -3.

Therefore, b=-3. This is because an input of 0 means that there is no movement on the x-axis, so we can determine where the where the linear intercepts the y-axis.

Therefore, the equation is y=2x-3, where m=2 and b=-3.

That’s the answer: y=2x-3
