-45+18x is the answer
Hope this helped <3
Answer:
Step-by-step explanation:
it is hard to know exactly by eye balling the graph I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it
the dots on the line are at (-2, -6) and (2, 3) so we can find the slope m
in the y = mx + b line equation b is the y intercept
m = Δy/Δx = (y1 - y2) / (x1 - x2)
= (-6 - -3) / (-2 - 2)
= -3 / -4
m = 3/4
y = 3x/4 + y intercept which i can't dissern (read directly from the
graph, but we believe y = 0 when x is six
0 = 3(6)/4 + y intercept
-18/4 = 18/4 -18/4 + y intercept
-9/2 = y intercept
-4.5 = y intercept
y = 3x/4 - 9/2 i think exact number means NO FRACTIONS but that is whole number so let me gaggle it What are exact numbers? Gaggle indicates exact numbers are integers example 3 ft in a yard 12 eggs in a dozen
y = 3x/4 - 9/2 multiple both sides by 4
4y = 3x - 36/2
4y = 3x - 18 <------------------ FINAL ANSWER
Answer:
x = -1.5
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.2x + 1 = 1.6x + 3.1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 0.2x on both sides: 1 = 1.4x + 3.1
- Subtract 3.1 on both sides: -2.1 = 1.4x
- Divide both sides by 1.4: -1.5 = x
- Rewrite: x = -1.5
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitution: 0.2(-1.5) + 1 = 1.6(-1.5) + 3.1
- Multiply: -0.3 + 1 = -2.4 + 3.1
- Add: 0.7 = 0.7
C.) Add 5 more drops of blue food coloring and 1/2 teaspoon more of distilled vinegar
-34.44 +49.44 = 15
The highest recorded temperature was 15 degrees.
